Stroke Sustainable Use License
Version 1.0

Copyright (c) 2026 Nischal Dahal and Stroke contributors

Applies to stroke-web: the Stroke website, the licence service, the payment
integration, and the free AI proxy.

-------------------------------------------------------------------------------

Plain-English summary (not legally binding — the terms below govern):

  - You CAN read, audit, modify and build this source, and run it yourself for
    development, testing, or to satisfy yourself about what the service does
    with your data.
  - You CANNOT sell it, rebrand it, or run it as a service for other people.
  - You CANNOT use it to issue Stroke licences, or to stand up an alternative
    activation, update, or distribution endpoint for Stroke.
  - The official service runs at stroke.click.

This is the same licence as the Stroke desktop application, deliberately. This
repository is the service that issues and validates the licences that fund
Stroke, and takes payment. A backend on freer terms than the product it licenses
would be an open invitation to strip the gating and reroute the clients.

Terms

1. Grant. Subject to the conditions below, you are granted a worldwide,
   royalty-free, non-exclusive, non-transferable license to use, copy, modify,
   and create derivative works of this software, and to distribute copies of
   it, in source or compiled form, for any Permitted Purpose.

2. Permitted Purposes. A Permitted Purpose is any use EXCEPT:

   a. selling the software, charging any fee for it, or including it in a
      product or bundle that is sold or licensed for a fee;

   b. providing the software to third parties as a hosted, managed, or
      embedded service, whether paid or as part of a paid offering;

   c. distributing the software, modified or unmodified, under a different
      name or brand, or in a way that suggests it is your own product;

   d. operating it, in whole or in part, as a licence-issuing, licence-
      validating, activation, update, or distribution endpoint for Stroke, or
      configuring any Stroke build to use such an endpoint other than the
      official one. (You may run it locally for development, testing, and
      contribution.)

3. Conditions. Any copy or substantial portion you distribute must retain this
   license text, the copyright notice above, and a link to the official
   repository. Modified copies must be clearly marked as modified.

   other trademarks of the copyright holder.

6. Contributions. Unless you and the copyright holder agree otherwise in
   writing, contributions you submit to the official repository may be
   distributed under this license.

7. Termination. Your rights under this license end automatically if you
   breach it. Rights are reinstated if the breach is fully cured within 30
   days of you becoming aware of it, unless the copyright holder notifies you
   otherwise.

8. Warranty and liability. THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY
   OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE
