Terms of Use

Last updated: 29 October 2026

In short: Tuck is free, open-source software. You may use, study, change and share it under the GNU GPL v3. It comes without warranty, and you remain responsible for what you copy and paste.

1. Who we are

Tuck and tuckshelf.app are provided by Vladyslav Korobka (trading as Promin), Zimmerstrasse 95, 10117 Berlin, Germany. See the imprint for full contact details.

2. Software licence

The Tuck source code is licensed under the GNU General Public License v3.0. That licence governs your rights to use, copy, modify and distribute the software, and these terms do not limit them.

If you download Tuck from Apple's App Store, Apple's Standard Licensed Application End User License Agreement also applies to that copy. Apple is not responsible for Tuck or its support.

3. Using Tuck

Tuck saves what you copy. Use its exclusion settings for apps that handle passwords or other sensitive data, and check what you sync to iCloud Drive.
You are responsible for content you copy, store, sync and paste with Tuck, and for complying with the rules of the apps and services you use it with.
Don't use Tuck to break the law or other people's rights.

4. Warranty and liability

Tuck is provided free of charge and “as is”. As set out in sections 15 and 16 of the GPL v3, there is no warranty to the extent permitted by law.

Under German law, we are liable without limitation for damage caused intentionally or through gross negligence, for injury to life, body or health, and under the Product Liability Act. For slight negligence we are liable only for breach of an essential contractual obligation, limited to the typical, foreseeable damage. As the software is provided free of charge (a gift under §§ 521, 524 BGB), our liability is otherwise limited to intent and gross negligence. Keep backups of anything important.

5. The website

We keep tuckshelf.app accurate but cannot guarantee it is complete, current or always available. Links to other sites are provided for convenience; their operators are responsible for their content.

6. Trademarks

“Tuck” and the Tuck logo identify this project. The GPL does not grant rights to use them for modified versions; please give your fork its own name and icon. Apple, Mac, iPhone and iCloud are trademarks of Apple Inc.

7. Changes and law

We may update these terms when the apps or website change; the date above shows the current version. German law applies, except where the mandatory consumer protection law of your country of residence gives you more protection.
