OPENWORTHY SOFTWARE LICENCE

Copyright (c) 2026 The OpenWorthy Authors. All rights reserved.

This licence is an agreement between you and the authors of OpenWorthy
("we", "us") about your use of the OpenWorthy software, including its
desktop app, command-line program, installers, container images and updates
(the "Software"). By installing or using the Software you accept these
terms. If you do not accept them, do not install or use it.

1. WHAT YOU MAY DO

   We grant you a non-exclusive, non-transferable, worldwide licence to
   install and use the Software, for personal or business purposes, on any
   number of computers that you own or control.

2. FREE AND PRO

   The Software's Free features may be used without payment.

   Its Pro features need a valid licence key, issued by us when you buy Pro.
   A Pro licence covers every version line of the Software that began on or
   before the date shown in your licence, including every later fix
   released for those lines, for as long as you use them. A founder licence
   covers every version, for the life of OpenWorthy. The pricing page on
   our website describes the plans in detail.

3. WHAT YOU MAY NOT DO

   You may not, and may not help others to:
   (a) move, change, disable or circumvent the licence-key check, or modify
       the Software to give access to Pro features without a valid key;
   (b) copy, modify, adapt or create derivative works of the Software,
       except as needed to install and use it;
   (c) reverse engineer, decompile or disassemble the Software, except to
       the extent that applicable law permits this despite this term;
   (d) sell, rent, lend, sublicense or distribute the Software, or offer it
       as a service to others, except by passing on our unmodified official
       installers and download links; or
   (e) share, publish or sell licence keys.

4. THIRD-PARTY SOFTWARE

   The Software includes open-source components, listed with their licences
   in THIRD_PARTY_NOTICES.txt. Those components are licensed to you under
   their own licences, which prevail over this licence for those components.

5. YOUR DATA

   The Software runs on your computer. It reads the headers of your email
   directly from your mail provider and stores what it learns only on your
   computer. Nothing about you or your mail is sent to us. The Software
   checks for updates by downloading a public file from our website, which
   you can switch off. Buying Pro takes place in your web browser on our
   payment provider's pages, under their terms and privacy policy.

6. UPDATES AND SUPPORT

   We may release updates to fix problems or add features. Fixes are
   released for the newest version line; security fixes are also released
   for the previous version line for twelve months after the newest line
   begins. Pro and founder licences include support by email.

7. IF OPENWORTHY IS DISCONTINUED

   If we stop developing OpenWorthy, we will publish a final release in
   which every Pro feature is available without a licence key.

8. PURCHASES, RENEWALS AND REFUNDS

   Pro is sold by our reseller, Paddle, who is the merchant of record for
   every purchase. Prices, renewals, cancellation and refunds are governed
   by the terms shown at checkout and on our website. Cancelling a renewal
   never removes what you have already paid for (section 2).

9. NO WARRANTY

   The Software is provided "as is", without warranty of any kind, express
   or implied, including warranties of merchantability, fitness for a
   particular purpose and non-infringement. The Software adds and removes
   its own marker on your email and never deletes or moves messages, but
   you are responsible for your own backups and for how you use it.

10. LIMITATION OF LIABILITY

    To the fullest extent permitted by law, we are not liable for any
    indirect, incidental, special or consequential damages, or for loss of
    data, profits or business, arising from the Software or this licence.
    Our total liability for any claim is limited to the amount you paid us
    for the Software in the twelve months before the claim. Nothing in this
    licence limits liability that cannot be limited by law, or your rights
    as a consumer that cannot be waived.

11. ENDING THIS LICENCE

    This licence ends automatically if you break its terms. When it ends
    you must stop using the Software and delete your copies. Sections 4
    and 9 to 12 continue to apply.

12. GENERAL

    If any part of this licence is found unenforceable, the rest remains in
    effect. This licence is the whole agreement between you and us about the
    Software, alongside any terms you accept when buying Pro. We may publish
    a new version of this licence with a new version of the Software; the
    licence shipped with each version applies to that version.
