1. Acceptance
By installing or using Hourglass (the project name is Clepsydra; "the app"), published by Michał Daniel Dobrzański ("we", "us"), you agree to these terms. If you do not agree, do not use the app.
2. The service
The app is an hourglass-style countdown timer with a simulated sand animation and optional alarm notifications. It works offline, requires no account, and has no paid features.
3. License to use
We grant you a personal, non-exclusive, non-transferable, revocable license to use the app on devices you own or control, subject to the rules of the store you obtained it from (Google Play or the Apple App Store). You may not redistribute, sell, or sublicense the app itself.
4. Do not rely on it for critical timing
The app is a convenience timer. Operating systems may delay, silence, or suppress alarms and notifications (battery savers, Focus/Do Not Disturb modes, forced app stops, powered-off devices, denied notification permissions). Do not use the app where missing or late alerts could cause harm — including medical, safety, professional, or other critical timing purposes.
5. No warranty
The app is provided "as is" and "as available", without warranties of any kind, express or implied, including merchantability, fitness for a particular purpose, accuracy, and non-infringement. We do not warrant that the app will be uninterrupted or error-free.
6. Limitation of liability
To the maximum extent permitted by applicable law, we shall not be liable for any indirect, incidental, special, consequential, or punitive damages, or for any loss of data, profits, or opportunities, arising from or related to your use of (or inability to use) the app. Where liability cannot be excluded, it is limited to the amount you paid for the app (the app is free, so: zero), or the minimum amount required by law. Nothing in these terms excludes liability that cannot be excluded by law, including under consumer-protection rules in your country.
7. Intellectual property
The app, its design, and its content are our property or used under license. The project's source code is available on GitHub; its use is governed by the license stated in that repository.
8. Privacy
The app uses privacy-respecting anonymous usage analytics (no advertising ID) and collects no other data. See the Privacy Policy for details.
9. Changes to the app or these terms
We may update the app or these terms at any time. Material changes will be reflected on this page with a new effective date. Continuing to use the app after a change means you accept the updated terms.
10. Termination
You can stop using the app at any time by uninstalling it. We may discontinue the app or its distribution at any time.
11. Governing law
These terms are governed by the laws of Poland, without prejudice to any mandatory consumer protections of the country in which you reside.
