The particular version of the Library -with which the Combined Work was made is also called the "Linked -Version". - -The "Minimal Corresponding Source" for a Combined Work means the -Corresponding Source for the Combined Work, excluding any source code -for portions of the Combined Work that, considered in isolation, are -based on the Application, and not on the Linked Version. - -The "Corresponding Application Code" for a Combined Work means the -object code and/or source code for the Application, including any data -and utility programs needed for reproducing the Combined Work from the -Application, but excluding the System Libraries of the Combined Work. - -##### 1. Exception to Section 3 of the GNU GPL. - -You may convey a covered work under sections 3 and 4 of this License -without being bound by section 3 of the GNU GPL. - -##### 2.

Object Code Incorporating Material from Library Header Files. - -The object code form of an Application may incorporate material from a -header file that is part of the Library. You may convey such object -code under terms of your choice, provided that, if the incorporated -material is not limited to numerical parameters, data structure -layouts and accessors, or small macros, inline functions and templates -(ten or fewer lines in length), you do both of the following: - -- a) Give prominent notice with each copy of the object code that - the Library is used in it and that the Library and its use are - covered by this License. -- b) Accompany the object code with a copy of the GNU GPL and this - license document. - -##### 4. Combined Works. - -You may convey a Combined Work under terms of your choice that, taken -together, effectively do not restrict modification of the portions of -the Library contained in the Combined Work and reverse engineering for -debugging such modifications, if you also do each of the following: - -- a) Give prominent notice with each copy of the Combined Work that - the Library is used in it and that the Library and its use are - covered by this License. -- b) Accompany the Combined Work with a copy of the GNU GPL and this - license document. -- c) For a Combined Work that displays copyright notices during - execution, include the copyright notice for the Library among - these notices, as well as a reference directing the user to the - copies of the GNU GPL and this license document. -- d) Do one of the following: - - 0) Convey the Minimal Corresponding Source under the terms of - this License, and the Corresponding Application Code in a form - suitable for, and under terms that permit, the user to - recombine or relink the Application with a modified version of - the Linked Version to produce a modified Combined Work, in the - manner specified by section 6 of the GNU GPL for conveying - Corresponding Source. - - 1) Use a suitable shared library mechanism for linking with - the Library.

statement of acceptance of any version is -permanent authorization for you to choose that version for the -Library. \ No newline at end of file diff --git a/backend.go b/backend.go index

Our General Public Licenses are designed to make sure that you -have the freedom to distribute copies of free software (and charge for -them if you wish), that you receive source code or can get it if you -want it, that you can change the software or use pieces of it in new -free programs, and that you know you can do these things. - -Developers that use our General Public Licenses protect your rights -with two steps: (1) assert copyright on the software, and (2) offer -you this License which gives you legal permission to copy, distribute -and/or modify the software. - -A secondary benefit of defending all users' freedom is that -improvements made in alternate versions of the program, if they -receive widespread use, become available for other developers to -incorporate. Many developers of free software are heartened and -encouraged by the resulting cooperation. However, in the case of -software used on network servers, this result may fail to come about. -The GNU General Public License permits making a modified version and -letting the public access it on a server without ever releasing its -source code to the public. - -The GNU Affero General Public License is designed specifically to -ensure that, in such cases, the modified source code becomes available -to the community. It requires the operator of a network server to -provide the source code of the modified version running there to the -users of that server. Therefore, public use of a modified version, on -a publicly accessible server, gives the public access to the source -code of the modified version. - -An older license, called the Affero General Public License and -published by Affero, was designed to accomplish similar goals. This is -a different license, not a version of the Affero GPL, but Affero has -released a new version of the Affero GPL which permits relicensing -under this license. - -The precise terms and conditions for copying, distribution and -modification follow. - -## TERMS AND CONDITIONS - -### 0. Definitions. - -"This License" refers to version 3 of the GNU Affero General Public -License. - -"Copyright" also means copyright-like laws that apply to other kinds -of works, such as semiconductor masks. - -"The Program" refers to any copyrightable work licensed under this -License. Each licensee is addressed as "you". "Licensees" and -"recipients" may be individuals or organizations. - -To "modify" a work means to copy from or adapt all or part of the work -in a fashion requiring copyright permission, other than the making of -an exact copy. The resulting work is called a "modified version" of -the earlier work or a work "based on" the earlier work. - -A "covered work" means either the unmodified Program or a work based -on the Program. - -To "propagate" a work means to do anything with it that, without -permission, would make you directly or secondarily liable for -infringement under applicable copyright law, except executing it on a -computer or modifying a private copy. Propagation includes copying, -distribution (with or without modification), making available to the -public, and in some countries other activities as well. - -To "convey" a work means any kind of propagation that enables other -parties to make or receive copies. Mere interaction with a user -through a computer network, with no transfer of a copy, is not -conveying. - -An interactive user interface displays "Appropriate Legal Notices" to -the extent that it includes a convenient and prominently visible -feature that (1) displays an appropriate copyright notice, and (2) -tells the user that there is no warranty for the work (except to the -extent that warranties are provided), that licensees may convey the -work under this License, and how to view a copy of this License. If -the interface presents a list of user commands or options, such as a -menu, a prominent item in the list meets this criterion. - -### 1. Source Code. - -The "source code" for a work means the preferred form of the work for -making modifications to it. "Object code" means any non-source form of -a work. - -A "Standard Interface" means an interface that either is an official -standard defined by a recognized standards body, or, in the case of -interfaces specified for a particular programming language, one that -is widely used among developers working in that language. - -The "System Libraries" of an executable work include anything, other -than the work as a whole, that (a) is included in the normal form of -packaging a Major Component, but which is not part of that Major -Component, and (b) serves only to enable use of the work with that -Major Component, or to implement a Standard Interface for which an -implementation is available to the public in source code form. A -"Major Component", in this context, means a major essential component -(kernel, window system, and so on) of the specific operating system -(if any) on which the executable work runs, or a compiler used to -produce the work, or an object code interpreter used to run it. - -The "Corresponding Source" for a work in object code form means all -the source code needed to generate, install, and (for an executable -work) run the object code and to modify the work, including scripts to -control those activities. However, it does not include the work's -System Libraries, or general-purpose tools or generally available free -programs which are used unmodified in performing those activities but -which are not part of the work. For example, Corresponding Source -includes interface definition files associated with source files for -the work, and the source code for shared libraries and dynamically -linked subprograms that the work is specifically designed to require, -such as by intimate data communication or control flow between those -subprograms and other parts of the work. - -The Corresponding Source need not include anything that users can -regenerate automatically from other parts of the Corresponding Source. - -The Corresponding Source for a work in source code form is that same -work. - -### 2. Basic Permissions. - -All rights granted under this License are granted for the term of -copyright on the Program, and are irrevocable provided the stated -conditions are met. This License explicitly affirms your unlimited -permission to run the unmodified Program. The output from running a -covered work is covered by this License only if the output, given its -content, constitutes a covered work. This License acknowledges your -rights of fair use or other equivalent, as provided by copyright law. - -You may make, run and propagate covered works that you do not convey, -without conditions so long as your license otherwise remains in force. -You may convey covered works to others for the sole purpose of having -them make modifications exclusively for you, or provide you with -facilities for running those works, provided that you comply with the -terms of this License in conveying all material for which you do not -control copyright. Those thus making or running the covered works for -you must do so exclusively on your behalf, under your direction and -control, on terms that prohibit them from making any copies of your -copyrighted material outside their relationship with you. - -Conveying under any other circumstances is permitted solely under the -conditions stated below. Sublicensing is not allowed; section 10 makes -it unnecessary. - -### 3. Protecting Users' Legal Rights From Anti-Circumvention Law. - -No covered work shall be deemed part of an effective technological -measure under any applicable law fulfilling obligations under article -11 of the WIPO copyright treaty adopted on 20 December 1996, or -similar laws prohibiting or restricting circumvention of such -measures. - -When you convey a covered work, you waive any legal power to forbid -circumvention of technological measures to the extent such -circumvention is effected by exercising rights under this License with -respect to the covered work, and you disclaim any intention to limit -operation or modification of the work as a means of enforcing, against -the work's users, your or third parties' legal rights to forbid -circumvention of technological measures. - -### 4. Conveying Verbatim Copies. - -You may convey verbatim copies of the Program's source code as you -receive it, in any medium, provided that you conspicuously and -appropriately publish on each copy an appropriate copyright notice; -keep intact all notices stating that this License and any -non-permissive terms added in accord with section 7 apply to the code; -keep intact all notices of the absence of any warranty; and give all -recipients a copy of this License along with the Program. - -You may charge any price or no price for each copy that you convey, -and you may offer support or warranty protection for a fee. - -### 5. Conveying Modified Source Versions. - -You may convey a work based on the Program, or the modifications to -produce it from the Program, in the form of source code under the -terms of section 4, provided that you also meet all of these -conditions: - -- a) The work must carry prominent notices stating that you modified - it, and giving a relevant date. -- b) The work must carry prominent notices stating that it is - released under this License and any conditions added under - section 7. This requirement modifies the requirement in section 4 - to "keep intact all notices". -- c) You must license the entire work, as a whole, under this - License to anyone who comes into possession of a copy. This - License will therefore apply, along with any applicable section 7 - additional terms, to the whole of the work, and all its parts, - regardless of how they are packaged. This License gives no - permission to license the work in any other way, but it does not - invalidate such permission if you have separately received it. -- d) If the work has interactive user interfaces, each must display - Appropriate Legal Notices; however, if the Program has interactive - interfaces that do not display Appropriate Legal Notices, your - work need not make them do so. - -A compilation of a covered work with other separate and independent -works, which are not by their nature extensions of the covered work, -and which are not combined with it such as to form a larger program, -in or on a volume of a storage or distribution medium, is called an -"aggregate" if the compilation and its resulting copyright are not -used to limit the access or legal rights of the compilation's users -beyond what the individual works permit. Inclusion of a covered work -in an aggregate does not cause this License to apply to the other -parts of the aggregate. - -### 6. Conveying Non-Source Forms. - -You may convey a covered work in object code form under the terms of -sections 4 and 5, provided that you also convey the machine-readable -Corresponding Source under the terms of this License, in one of these -ways: - -- a) Convey the object code in, or embodied in, a physical product - (including a physical distribution medium), accompanied by the - Corresponding Source fixed on a durable physical medium - customarily used for software interchange. -- b) Convey the object code in, or embodied in, a physical product - (including a physical distribution medium), accompanied by a - written offer, valid for at least three years and valid for as - long as you offer spare parts or customer support for that product - model, to give anyone who possesses the object code either (1) a - copy of the Corresponding Source for all the software in the - product that is covered by this License, on a durable physical - medium customarily used for software interchange, for a price no - more than your reasonable cost of physically performing this - conveying of source, or (2) access to copy the Corresponding - Source from a network server at no charge. -- c) Convey individual copies of the object code with a copy of the - written offer to provide the Corresponding Source. This - alternative is allowed only occasionally and noncommercially, and - only if you received the object code with such an offer, in accord - with subsection 6b. -- d) Convey the object code by offering access from a designated - place (gratis or for a charge), and offer equivalent access to the - Corresponding Source in the same way through the same place at no - further charge. You need not require recipients to copy the - Corresponding Source along with the object code. If the place to - copy the object code is a network server, the Corresponding Source - may be on a different server (operated by you or a third party) - that supports equivalent copying facilities, provided you maintain - clear directions next to the object code saying where to find the - Corresponding Source. Regardless of what server hosts the - Corresponding Source, you remain obligated to ensure that it is - available for as long as needed to satisfy these requirements. -- e) Convey the object code using peer-to-peer transmission, - provided you inform other peers where the object code and - Corresponding Source of the work are being offered to the general - public at no charge under subsection 6d. - -A separable portion of the object code, whose source code is excluded -from the Corresponding Source as a System Library, need not be -included in conveying the object code work. - -A "User Product" is either (1) a "consumer product", which means any -tangible personal property which is normally used for personal, -family, or household purposes, or (2) anything designed or sold for -incorporation into a dwelling. In determining whether a product is a -consumer product, doubtful cases shall be resolved in favor of -coverage. For a particular product received by a particular user, -"normally used" refers to a typical or common use of that class of -product, regardless of the status of the particular user or of the way -in which the particular user actually uses, or expects or is expected -to use, the product. A product is a consumer product regardless of -whether the product has substantial commercial, industrial or -non-consumer uses, unless such uses represent the only significant -mode of use of the product. - -"Installation Information" for a User Product means any methods, -procedures, authorization keys, or other information required to -install and execute modified versions of a covered work in that User -Product from a modified version of its Corresponding Source. The -information must suffice to ensure that the continued functioning of -the modified object code is in no case prevented or interfered with -solely because modification has been made. - -If you convey an object code work under this section in, or with, or -specifically for use in, a User Product, and the conveying occurs as -part of a transaction in which the right of possession and use of the -User Product is transferred to the recipient in perpetuity or for a -fixed term (regardless of how the transaction is characterized), the -Corresponding Source conveyed under this section must be accompanied -by the Installation Information. But this requirement does not apply -if neither you nor any third party retains the ability to install -modified object code on the User Product (for example, the work has -been installed in ROM). - -The requirement to provide Installation Information does not include a -requirement to continue to provide support service, warranty, or -updates for a work that has been modified or installed by the -recipient, or for the User Product in which it has been modified or -installed. Access to a network may be denied when the modification -itself materially and adversely affects the operation of the network -or violates the rules and protocols for communication across the -network. - -Corresponding Source conveyed, and Installation Information provided, -in accord with this section must be in a format that is publicly -documented (and with an implementation available to the public in -source code form), and must require no special password or key for -unpacking, reading or copying. - -### 7. Additional Terms. - -"Additional permissions" are terms that supplement the terms of this -License by making exceptions from one or more of its conditions. -Additional permissions that are applicable to the entire Program shall -be treated as though they were included in this License, to the extent -that they are valid under applicable law. If additional permissions -apply only to part of the Program, that part may be used separately -under those permissions, but the entire Program remains governed by -this License without regard to the additional permissions. - -When you convey a copy of a covered work, you may at your option -remove any additional permissions from that copy, or from any part of -it. (Additional permissions may be written to require their own -removal in certain cases when you modify the work.) You may place -additional permissions on material, added by you to a covered work, -for which you have or can give appropriate copyright permission. - -Notwithstanding any other provision of this License, for material you -add to a covered work, you may (if authorized by the copyright holders -of that material) supplement the terms of this License with terms: - -- a) Disclaiming warranty or limiting liability differently from the - terms of sections 15 and 16 of this License; or -- b) Requiring preservation of specified reasonable legal notices or - author attributions in that material or in the Appropriate Legal - Notices displayed by works containing it; or -- c) Prohibiting misrepresentation of the origin of that material, - or requiring that modified versions of such material be marked in - reasonable ways as different from the original version; or -- d) Limiting the use for publicity purposes of names of licensors - or authors of the material; or -- e) Declining to grant rights under trademark law for use of some - trade names, trademarks, or service marks; or -- f) Requiring indemnification of licensors and authors of that - material by anyone who conveys the material (or modified versions - of it) with contractual assumptions of liability to the recipient, - for any liability that these contractual assumptions directly - impose on those licensors and authors. - -All other non-permissive additional terms are considered "further -restrictions" within the meaning of section 10. If the Program as you -received it, or any part of it, contains a notice stating that it is -governed by this License along with a term that is a further -restriction, you may remove that term. If a license document contains -a further restriction but permits relicensing or conveying under this -License, you may add to a covered work material governed by the terms -of that license document, provided that the further restriction does -not survive such relicensing or conveying. - -If you add terms to a covered work in accord with this section, you -must place, in the relevant source files, a statement of the -additional terms that apply to those files, or a notice indicating -where to find the applicable terms. - -Additional terms, permissive or non-permissive, may be stated in the -form of a separately written license, or stated as exceptions; the -above requirements apply either way. - -### 8. Termination. - -You may not propagate or modify a covered work except as expressly -provided under this License. Any attempt otherwise to propagate or -modify it is void, and will automatically terminate your rights under -this License (including any patent licenses granted under the third -paragraph of section 11). - -However, if you cease all violation of this License, then your license -from a particular copyright holder is reinstated (a) provisionally, -unless and until the copyright holder explicitly and finally -terminates your license, and (b) permanently, if the copyright holder -fails to notify you of the violation by some reasonable means prior to -60 days after the cessation. - -Moreover, your license from a particular copyright holder is -reinstated permanently if the copyright holder notifies you of the -violation by some reasonable means, this is the first time you have -received notice of violation of this License (for any work) from that -copyright holder, and you cure the violation prior to 30 days after -your receipt of the notice. - -Termination of your rights under this section does not terminate the -licenses of parties who have received copies or rights from you under -this License. If your rights have been terminated and not permanently -reinstated, you do not qualify to receive new licenses for the same -material under section 10. - -### 9. Acceptance Not Required for Having Copies. - -You are not required to accept this License in order to receive or run -a copy of the Program. Ancillary propagation of a covered work -occurring solely as a consequence of using peer-to-peer transmission -to receive a copy likewise does not require acceptance. However, -nothing other than this License grants you permission to propagate or -modify any covered work. These actions infringe copyright if you do -not accept this License. Therefore, by modifying or propagating a -covered work, you indicate your acceptance of this License to do so. - -### 10. Automatic Licensing of Downstream Recipients. - -Each time you convey a covered work, the recipient automatically -receives a license from the original licensors, to run, modify and -propagate that work, subject to this License. You are not responsible -for enforcing compliance by third parties with this License. - -An "entity transaction" is a transaction transferring control of an -organization, or substantially all assets of one, or subdividing an -organization, or merging organizations. If propagation of a covered -work results from an entity transaction, each party to that -transaction who receives a copy of the work also receives whatever -licenses to the work the party's predecessor in interest had or could -give under the previous paragraph, plus a right to possession of the -Corresponding Source of the work from the predecessor in interest, if -the predecessor has it or can get it with reasonable efforts. - -You may not impose any further restrictions on the exercise of the -rights granted or affirmed under this License. For example, you may -not impose a license fee, royalty, or other charge for exercise of -rights granted under this License, and you may not initiate litigation -(including a cross-claim or counterclaim in a lawsuit) alleging that -any patent claim is infringed by making, using, selling, offering for -sale, or importing the Program or any portion of it. - -### 11. Patents. - -A "contributor" is a copyright holder who authorizes use under this -License of the Program or a work on which the Program is based. The -work thus licensed is called the contributor's "contributor version". - -A contributor's "essential patent claims" are all patent claims owned -or controlled by the contributor, whether already acquired or -hereafter acquired, that would be infringed by some manner, permitted -by this License, of making, using, or selling its contributor version, -but do not include claims that would be infringed only as a -consequence of further modification of the contributor version. For -purposes of this definition, "control" includes the right to grant -patent sublicenses in a manner consistent with the requirements of -this License. - -Each contributor grants you a non-exclusive, worldwide, royalty-free -patent license under the contributor's essential patent claims, to -make, use, sell, offer for sale, import and otherwise run, modify and -propagate the contents of its contributor version. - -In the following three paragraphs, a "patent license" is any express -agreement or commitment, however denominated, not to enforce a patent -(such as an express permission to practice a patent or covenant not to -sue for patent infringement). To "grant" such a patent license to a -party means to make such an agreement or commitment not to enforce a -patent against the party. - -If you convey a covered work, knowingly relying on a patent license, -and the Corresponding Source of the work is not available for anyone -to copy, free of charge and under the terms of this License, through a -publicly available network server or other readily accessible means, -then you must either (1) cause the Corresponding Source to be so -available, or (2) arrange to deprive yourself of the benefit of the -patent license for this particular work, or (3) arrange, in a manner -consistent with the requirements of this License, to extend the patent -license to downstream recipients. "Knowingly relying" means you have -actual knowledge that, but for the patent license, your conveying the -covered work in a country, or your recipient's use of the covered work -in a country, would infringe one or more identifiable patents in that -country that you have reason to believe are valid. - -If, pursuant to or in connection with a single transaction or -arrangement, you convey, or propagate by procuring conveyance of, a -covered work, and grant a patent license to some of the parties -receiving the covered work authorizing them to use, propagate, modify -or convey a specific copy of the covered work, then the patent license -you grant is automatically extended to all recipients of the covered -work and works based on it. - -A patent license is "discriminatory" if it does not include within the -scope of its coverage, prohibits the exercise of, or is conditioned on -the non-exercise of one or more of the rights that are specifically -granted under this License. You may not convey a covered work if you -are a party to an arrangement with a third party that is in the -business of distributing software, under which you make payment to the -third party based on the extent of your activity of conveying the -work, and under which the third party grants, to any of the parties -who would receive the covered work from you, a discriminatory patent -license (a) in connection with copies of the covered work conveyed by -you (or copies made from those copies), or (b) primarily for and in -connection with specific products or compilations that contain the -covered work, unless you entered into that arrangement, or that patent -license was granted, prior to 28 March 2007. - -Nothing in this License shall be construed as excluding or limiting -any implied license or other defenses to infringement that may -otherwise be available to you under applicable patent law. - -### 12. No Surrender of Others' Freedom. - -If conditions are imposed on you (whether by court order, agreement or -otherwise) that contradict the conditions of this License, they do not -excuse you from the conditions of this License. If you cannot convey a -covered work so as to satisfy simultaneously your obligations under -this License and any other pertinent obligations, then as a -consequence you may not convey it at all. For example, if you agree to -terms that obligate you to collect a royalty for further conveying -from those to whom you convey the Program, the only way you could -satisfy both those terms and this License would be to refrain entirely -from conveying the Program. - -### 13. Remote Network Interaction; Use with the GNU General Public License. - -Notwithstanding any other provision of this License, if you modify the -Program, your modified version must prominently offer all users -interacting with it remotely through a computer network (if your -version supports such interaction) an opportunity to receive the -Corresponding Source of your version by providing access to the -Corresponding Source from a network server at no charge, through some -standard or customary means of facilitating copying of software. This -Corresponding Source shall include the Corresponding Source for any -work covered by version 3 of the GNU General Public License that is -incorporated pursuant to the following paragraph. - -Notwithstanding any other provision of this License, you have -permission to link or combine any covered work with a work licensed -under version 3 of the GNU General Public License into a single -combined work, and to convey the resulting work. The terms of this -License will continue to apply to the part which is the covered work, -but the work with which it is combined will remain governed by version -3 of the GNU General Public License. - -### 14. Revised Versions of this License. - -The Free Software Foundation may publish revised and/or new versions -of the GNU Affero General Public License from time to time. Such new -versions will be similar in spirit to the present version, but may -differ in detail to address new problems or concerns. - -Each version is given a distinguishing version number. If the Program -specifies that a certain numbered version of the GNU Affero General -Public License "or any later version" applies to it, you have the -option of following the terms and conditions either of that numbered -version or of any later version published by the Free Software -Foundation. If the Program does not specify a version number of the -GNU Affero General Public License, you may choose any version ever -published by the Free Software Foundation. - -If the Program specifies that a proxy can decide which future versions -of the GNU Affero General Public License can be used, that proxy's -public statement of acceptance of a version permanently authorizes you -to choose that version for the Program. - -Later license versions may give you additional or different -permissions. However, no additional obligations are imposed on any -author or copyright holder as a result of your choosing to follow a -later version. - -### 15. Disclaimer of Warranty. - -THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY -APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT -HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT -WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT -LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR -A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND -PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE -DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR -CORRECTION. - -### 16. Limitation of Liability. - -IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING -WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR -CONVEYS THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, -INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES -ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT -NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR -LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM -TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER -PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. - -### 17. Interpretation of Sections 15 and 16. - -If the disclaimer of warranty and limitation of liability provided -above cannot be given local legal effect according to their terms, -reviewing courts shall apply local law that most closely approximates -an absolute waiver of all civil liability in connection with the -Program, unless a warranty or assumption of liability accompanies a -copy of the Program in return for a fee. - -END OF TERMS AND CONDITIONS - -## How to Apply These Terms to Your New Programs - -If you develop a new program, and you want it to be of the greatest -possible use to the public, the best way to achieve this is to make it -free software which everyone can redistribute and change under these -terms. - -To do so, attach the following notices to the program. It is safest to -attach them to the start of each source file to most effectively state -the exclusion of warranty; and each file should have at least the -"copyright" line and a pointer to where the full notice is found. - - - Copyright (C) - - This program is free software: you can redistribute it and/or modify - it under the terms of the GNU Affero General Public License as - published by the Free Software Foundation, either version 3 of the - License, or (at your option) any later version. - - This program is distributed in the hope that it will be useful, - but WITHOUT ANY WARRANTY; without even the implied warranty of - MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the - GNU Affero General Public License for more details. - - You should have received a copy of the GNU Affero General Public License - along with this program. If not, see . - -Also add information on how to contact you by electronic and paper -mail. - -If your software can interact with users remotely through a computer -network, you should also make sure that it provides a way for users to -get its source.

Kittemail

-

Kittemail is a free, open-source email service that respects your privacy.

- Open Kittemail -

Is it free?

-

Yes! Kittemail is free to use, and always will be.

-

You are allowed, by default, 25MB of storage. If you need any more, we will consider increasing your storage limit (chances are increased if , it isn't free to us to run this service :P).

-

What about email aliases?

-

Kittemail supports email aliases! Contact us if you would like to set up an email alias.

-

Due to this being in... beta, we currently do not automate this process. We will get back to you as soon as possible.

-

What about security?

-

Kittemail is secure, we hope...

-

Note: Kittemail is still in development. Please report any issues to our issue tracker.

Signed up!

-

Amazing! You've signed up for Kittemail. Now, let's get you set up.

-

Let's open up your email client and get you started.

-

IMAP/SMTP settings

-

Most modern email clients will automatically detect these settings, but if you need them, here they are:

-
    -
  • Username: Loading...
    • -
  • Password: Loading...
    • -
  • IMAP server: mail.ailur.dev OR mail.cta.social (both work)
    • -
  • IMAP port: 993
    • -
  • IMAP security: SSL/TLS
    • -
  • IMAP auth method: Normal password
    • -
  • SMTP server: mail.ailur.dev OR mail.cta.social (both work)
    • -
  • SMTP port: 465
    • -
  • SMTP security: SSL/TLS
    • -
  • SMTP auth method: Normal password
    • -
-

Webmail

-

Due to security concerns, we do not have a webmail client. We recommend using a desktop email client, such as Thunderbird, or a mobile email client, such as K-9 Mail.

-

The "security concerns" are that due to the nature of webmail, it is impossible to not store a plaintext copy of your email password. This has been mitigated using our email-specific login-code system, but most webmail clients would not support this, and it is inexcusable for a user to have to perform the hack we use for desktop email clients on an integrated webmail client.

-

Thank you for understanding.
