Terms of use for Tidelle

Last updated: 5 November 2026. The German version counts; this translation is for convenience. Deutsche Fassung

1. Who offers this and what it covers

These terms cover the app Tidelle, offered by Patrick Schad; the full address is in the legal notice. Contact: hi@tidelle.app. They are addressed to the adult who installs the app or buys in it.

2. What the app is

Tidelle works with no account and no login. What the app saves stays on your device, unless you choose a backup folder yourself. Details are in the privacy policy.

3. Cost

The app is free to download. More content or features are unlocked by a one-time in-app purchase, never a subscription. You see the price in the store before you buy.

4. Buying, restoring and refunds

Payment runs through the App Store or Google Play, and their terms also apply to it. A purchase belongs to your store account: you bring it back with the app's restore purchases option. It doesn't move between the App Store and Google Play. You request refunds from the store you bought in. If you bought on Google Play and it has been more than 48 hours, write to us.

5. Your legal rights

These terms don't affect your statutory consumer rights, including withdrawal and warranty.

6. What you may do with the app

You may use the app for yourself and your family. You may not resell it, and you may not change or take it apart unless the law expressly allows you to. The rights in the app and its content stay with the provider.

7. Updates

The app keeps developing, so content and features can change. We provide the updates needed to use the app and keep it secure, within the legal framework. We won't take away what you bought through an update without good reason.

8. Backing up your data

Because everything is on your device, we can't restore it for you. It can be lost when you delete the app or change device, unless you back it up yourself.

9. Liability

We're fully liable for intent and gross negligence, for injury to life, body or health, and under the German Product Liability Act. For slight negligence we're liable only if an essential contractual duty is breached, and then only for foreseeable, typical damage. Otherwise liability is excluded.

10. Changes

If these terms change, the new version appears on this page. For purchases already made, they don't change your rights without your consent.

11. Law and disputes

German law applies. Mandatory consumer protection rules of the country you live in are not affected. We don't take part in dispute resolution before a consumer arbitration board.

Tidelle

Tidelle estimates from your own entries when your next period and fertile window may be. These are estimates and they can be wrong. Tidelle is not a contraceptive and is not suitable for preventing or planning a pregnancy. It gives no medical advice and makes no diagnoses. For questions about your health, contact a medical professional. Reminders, such as for the pill, can fail if the device doesn't deliver them, so don't rely on them alone.
