Popback — End User Licence Agreement

Last updated 29 May 2026

Agreement

This End User Licence Agreement (the "Agreement") is a legal agreement between you ("you") and the developer of Popback ("we", "us", or "Popback") for the Popback software application (the "Software"). By installing or using the Software, you agree to be bound by this Agreement. If you do not agree, do not install or use the Software.

1. Licence

We grant you a personal, non-exclusive, non-transferable, revocable licence to install and use the Software on Mac computers that you own or control, for your own personal or internal business use, in accordance with this Agreement.

2. Restrictions

You may not: (a) copy, distribute, resell, rent, lease, sub-licence, or lend the Software; (b) modify, adapt, translate, reverse-engineer, decompile, or disassemble the Software, except where this restriction is prohibited by law; (c) remove or alter any copyright, trademark, or other proprietary notices; or (d) use the Software in any way that breaks applicable law.

3. Ownership

The Software is licensed, not sold. We and our licensors retain all right, title, and interest in and to the Software, including all intellectual property rights in it. This Agreement grants you no rights to our trademarks, branding, or name.

4. What Popback does — and what it cannot guarantee

Popback hides and restores windows by working alongside macOS and other applications. Because it depends on macOS and on software made by other developers, its behaviour cannot be guaranteed. In particular, and without limitation, you acknowledge and accept that:

• a snoozed window may not return at the expected time, may return changed, or may not return at all;
• the snooze controls — including the Popback bar — may not appear, may appear late, or may behave inconsistently;
• pending Popbacks are cleared if you shut down, restart, or log out of your Mac, if you quit Popback, or if the relevant application is quit or closed;
• updates to macOS, or to other applications, may change, impair, or break Popback's functionality at any time;
• the Software may contain errors or defects.

Popback is a convenience tool. It is not a backup system and it is not a guarantee that any window, document, or piece of work will be preserved or recovered. You remain responsible for saving your own work.

5. Disclaimer of warranties

THE SOFTWARE IS PROVIDED "AS IS" AND "AS AVAILABLE", WITHOUT WARRANTY OF ANY KIND, WHETHER EXPRESS, IMPLIED, OR STATUTORY. TO THE MAXIMUM EXTENT PERMITTED BY LAW, WE DISCLAIM ALL WARRANTIES, INCLUDING ANY IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, RELIABILITY, ACCURACY, QUIET ENJOYMENT, AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE SOFTWARE WILL BE UNINTERRUPTED, ERROR-FREE, OR SECURE, OR THAT IT WILL BE COMPATIBLE WITH ANY PARTICULAR VERSION OF macOS OR WITH ANY OTHER SOFTWARE.

6. macOS compatibility and future updates

Popback is supported only on the versions of macOS stated as compatible at the time of your purchase. Because Popback works alongside macOS, future updates to macOS — major or minor — may at any time change, impair, or completely stop Popback from working, with or without warning, and outside of our control.

While we intend to maintain Popback and to release updates that restore or improve compatibility, we do not guarantee that we will do so, nor that any fix will be provided within any particular timeframe, or at all. You accept that a future macOS update may render Popback partially or wholly non-functional, and you agree that this does not entitle you to any refund beyond what is required by law or offered by the store you purchased from, and does not give rise to any claim against us. If continued compatibility is essential to you, do not update macOS until you have confirmed that a compatible version of Popback is available.

7. Purchases and refunds

Popback is sold through third-party stores (for example Lemon Squeezy and Gumroad). Your purchase is a transaction with that store, and refunds, billing, taxes, and cancellations are governed by that store's terms and refund policy, together with any rights you have under applicable consumer law. We are not the seller of record for those transactions and do not separately process payments or refunds. Any refund request should be made to the store you purchased from. Nothing here removes or limits any non-waivable rights you have as a consumer.

8. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, IN NO EVENT WILL WE BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR EXEMPLARY DAMAGES, OR FOR ANY LOSS OF DATA, LOSS OF WORK, LOST OR UNRECOVERABLE WINDOWS, MISSED OR FAILED POPBACKS, LOSS OF PROFITS, LOSS OF GOODWILL, OR BUSINESS INTERRUPTION, ARISING OUT OF OR RELATING TO YOUR USE OF — OR INABILITY TO USE — THE SOFTWARE, EVEN IF WE HAVE BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES, AND REGARDLESS OF THE LEGAL THEORY ON WHICH THE CLAIM IS BASED.

TO THE MAXIMUM EXTENT PERMITTED BY LAW, OUR TOTAL AGGREGATE LIABILITY TO YOU FOR ALL CLAIMS RELATING TO THE SOFTWARE WILL NOT EXCEED THE AMOUNT YOU ACTUALLY PAID FOR THE SOFTWARE.

Nothing in this Agreement excludes or limits any liability that cannot be excluded or limited under applicable law — including, in some jurisdictions, liability for death or personal injury caused by negligence, or for fraud or fraudulent misrepresentation. This Agreement does not affect any mandatory legal rights you have as a consumer that cannot be waived.

9. Your responsibilities

You are responsible for using the Software in line with this Agreement and applicable law, for keeping your own backups, for saving your own work, and for the consequences of any reliance you place on the Software.

10. Termination

This Agreement applies until terminated. It terminates automatically, without notice, if you breach any part of it. On termination you must stop using the Software and remove it from your devices. Sections 3, 4, 5, 6, 7, 8, 9, 11, and 12 survive termination.

11. Updates and changes

We may release updates to the Software, and we may revise this Agreement from time to time. Where we revise it, the updated Agreement will be made available within the app and at www.popback.co.uk. Your continued use of the Software after a revised Agreement is made available constitutes your acceptance of the revised terms.

12. Governing law

This Agreement is governed by the laws of England and Wales, and you agree to the exclusive jurisdiction of the courts of England and Wales — without prejudice to any mandatory consumer-protection rights you have under the laws of your country of residence.

13. General

If any provision of this Agreement is found to be unenforceable, the remaining provisions remain in full force and effect. This Agreement is the entire agreement between you and us regarding the Software and supersedes any prior understanding.
