DOUGA - LICENSE AGREEMENT AND TERMS OF USE
Last updated: August 2, 2026

--------------------------------------------------------------------
 The short version
--------------------------------------------------------------------

  - Douga is free to use. Every feature works without a license key.
    Exports from an unlicensed copy carry a small Douga mark, and
    that's the only difference.
  - Everything you make with Douga is yours. All of it, always, no
    matter which version you use. Douga claims no rights over your
    work and asks for no credit.
  - A license key removes the export mark. A personal key covers an
    individual's own work, paid commissions and freelance included;
    the commercial key is for studios and companies.
  - Your key has your name and email signed into it. Keep it to
    yourself.
  - Douga is in beta and is provided as-is, with no warranty. Save
    often and keep backups of work you care about.

The full terms below are the agreement; the summary above is just a
summary.

--------------------------------------------------------------------
 The full terms
--------------------------------------------------------------------

1. WHO THIS IS BETWEEN

   This agreement is between you and Kei Hoag, the developer of
   Douga ("the developer"). By installing or using Douga you accept
   these terms. If you don't accept them, don't use the software.

2. THE SOFTWARE

   Douga is a 2D animation application for Windows. You may download
   it from the official page and use it free of charge, for any
   purpose, personal or commercial, for as long as you like. Every
   feature is enabled in the free version.

   Frames exported from an unlicensed copy carry a small Douga mark.
   The mark identifies the software, not you, and does not limit
   what you may do with your exports.

3. YOUR WORK IS YOURS

   Everything you create with Douga - every drawing, frame, and
   animation - belongs entirely to you. The developer claims no
   ownership of it, no license to it, and no credit for it. You may
   use, publish, and sell your work freely, whether or not you own
   a license key.

4. LICENSE KEYS

   A license key is issued to one person, with that person's name
   and email signed into it. You may use your key on any number of
   computers that are yours. A key may not be shared, published,
   resold, or transferred to someone else.

   There are two kinds of key:

   a. PERSONAL. For an individual buying with their own money and
      working on their own behalf. Removes the export mark from
      everything you make as that individual - hobby projects,
      studies, portfolio pieces, commissions, freelance work, and
      work you sell.

   b. COMMERCIAL. For organizations. If a studio, company, or other
      organization pays for the seat, or the copy is used for an
      organization's own productions, this is the license it needs.
      It removes the export mark for all work in any context. An
      organization that would rather not buy seats can still use
      the free version - the mark is the only difference.

   Keys are verified inside the app, offline. There is no activation
   server and no phone-home.

5. WHAT YOU MAY NOT DO

   You may not:

   a. share or publish a license key, or use a key issued to someone
      else;
   b. remove, disable, or bypass the export mark or the license
      check, or distribute copies of Douga modified to do so;
   c. create, forge, or sell license keys;
   d. redistribute Douga itself as your own or bundle it with other
      products without permission - link people to the official page
      instead, so they always get the current build.

6. BETA SOFTWARE

   Douga is in beta. It is stable enough to ship but it will have
   bugs, and a bug in an animation program can cost you work. Save
   often, and keep backups of anything you care about.

7. NO WARRANTY

   THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND,
   EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES
   OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND
   NONINFRINGEMENT. THE DEVELOPER DOES NOT WARRANT THAT THE SOFTWARE
   WILL BE ERROR-FREE OR UNINTERRUPTED, OR THAT DEFECTS WILL BE
   CORRECTED.

8. LIMITATION OF LIABILITY

   TO THE MAXIMUM EXTENT PERMITTED BY LAW, THE DEVELOPER SHALL NOT
   BE LIABLE FOR ANY DAMAGES ARISING OUT OF THE USE OF, OR INABILITY
   TO USE, THE SOFTWARE - INCLUDING LOST WORK, LOST DATA, LOST
   PROFITS, OR ANY INDIRECT, INCIDENTAL, SPECIAL, OR CONSEQUENTIAL
   DAMAGES - EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
   THE DEVELOPER'S TOTAL LIABILITY UNDER THIS AGREEMENT SHALL NOT
   EXCEED THE AMOUNT YOU PAID FOR YOUR LICENSE, IF ANY.

   Some jurisdictions do not allow certain warranty disclaimers or
   liability limits; where that is the case, the above apply to the
   fullest extent the law allows.

9. PRIVACY

   Douga has no accounts, no telemetry, and no analytics, and the
   application itself opens no network connections. The optional
   update-check plugin, if you choose to install it, asks the
   download page for the latest version number and sends nothing
   about you or your machine. Purchases are handled by the store you
   bought from, under that store's own terms and privacy policy.

10. REFUNDS

   Purchases are made through the store page (itch.io) and refunds
   are handled there, under the store's policies. If something is
   wrong, get in touch - see section 13.

11. TERMINATION

   Your license key's rights end if you materially breach this
   agreement (for example, by sharing your key or distributing a
   version with the mark bypassed). Sections 3, 7, 8, and 12 survive
   termination; your ownership of your own work is never affected.

12. THIRD-PARTY SOFTWARE

   Douga includes the following third-party components:

   - Dear ImGui, copyright (c) 2014-2026 Omar Cornut, used under
     the MIT License (reproduced below).
   - stb_image and stb_image_write by Sean Barrett, public domain.
   - TweetNaCl by Daniel J. Bernstein et al., public domain.

   The optional pose reference packs contain Eadweard Muybridge's
   motion studies from the 1880s, which are in the public domain.
   Video import and export use an ffmpeg installed and controlled
   by you; Douga does not include or distribute ffmpeg.

   The MIT License (for Dear ImGui):

     Permission is hereby granted, free of charge, to any person
     obtaining a copy of this software and associated documentation
     files (the "Software"), to deal in the Software without
     restriction, including without limitation the rights to use,
     copy, modify, merge, publish, distribute, sublicense, and/or
     sell copies of the Software, and to permit persons to whom the
     Software is furnished to do so, subject to the following
     conditions:

     The above copyright notice and this permission notice shall be
     included in all copies or substantial portions of the Software.

     THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND,
     EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES
     OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND
     NONINFRINGEMENT. IN NO EVENT SHALL THE AUTHORS OR COPYRIGHT
     HOLDERS BE LIABLE FOR ANY CLAIM, DAMAGES OR OTHER LIABILITY,
     WHETHER IN AN ACTION OF CONTRACT, TORT OR OTHERWISE, ARISING
     FROM, OUT OF OR IN CONNECTION WITH THE SOFTWARE OR THE USE OR
     OTHER DEALINGS IN THE SOFTWARE.

13. GENERAL

   If any part of this agreement is found unenforceable, the rest
   remains in effect. This is the entire agreement about the
   software between you and the developer. New versions of Douga
   may ship with updated terms, which apply to those versions.

   Questions, problems, or refund trouble: contact@douga.app, or
   the community board on the Douga page on itch.io
   (keihoag.itch.io/douga) - both reach the developer.
