Fasting Timer Privacy Policy
Last updated: 2026-10-10 (version 5.0 of the app)
This policy explains what information the Fasting Timer app ("the app") for iPhone collects, why, and what choices you have. The app is published by Endurance Apptitude ("we", "us").
The short version
- Your fasting data stays on your device. Your fasts, plan, water and weight logs are stored only on your iPhone. We never receive them.
- Apple Health is optional. If you turn it on, the app saves the weight and water you log to Apple Health and reads your latest weight. Health data never leaves your device through us and is never used for advertising.
- We use anonymous analytics (Google Firebase Analytics) to understand how the app is used, for example which screens are opened or whether a fast was completed.
- We process purchases through RevenueCat, using an anonymous identifier, to know whether you have Premium.
- We have no accounts, no ads and no tracking across other companies' apps or websites. We do not sell your data.
1. Information that stays on your device
| Data | Where it lives | Do we receive it? |
|---|---|---|
| Fasts: start and end times, plan, goal | Your iPhone | No |
| Running fast (also shared with the app's widgets and Live Activity) | Your iPhone | No |
| Water intake per day, weight entries, goal weight | Your iPhone | No |
| Settings: notifications, units, onboarding answers (goal, experience) | Your iPhone | No |
- Data is kept in the app's local storage on your iPhone. The app has no server of its own and does not use iCloud sync.
- Notifications (fast complete, one hour left, stage alerts, daily reminder) are scheduled locally on your iPhone.
- CSV export (Premium) creates a file on your device that you choose where to share.
- Deleting the app deletes this data.
2. Apple Health (optional, Premium)
If you turn on Apple Health in Settings and grant permission:
- the app writes the weight and water you log in the app to Apple Health;
- the app reads your most recent weight from Apple Health to keep your weight chart up to date.
Health data is used only to provide these features. It is not sent to us, not shared with third parties, not used for advertising or marketing, and not stored in iCloud by the app. You can revoke access at any time in the Health app (Sharing → Apps → Fasting Timer).
3. Analytics (Google Firebase Analytics)
We use Firebase Analytics to learn how the app is used and improve it. It collects app events (for example "fast started", "paywall shown", "onboarding completed"), the plan chosen, whether a goal was reached, device and OS information, country and an app-instance identifier. It does not receive your fasting times, water, weight or Health data. Analytics data is not linked to your identity and is not used to track you across apps.
4. Purchases (RevenueCat and Apple)
Purchases are processed by Apple. We use RevenueCat to check whether you have an active Premium subscription or lifetime purchase. RevenueCat receives an anonymous app user ID, purchase receipts and the device's country. We never see your name, email or payment details.
5. Children
The app is not directed to children under 13 and we do not knowingly collect information from them. Fasting is not recommended for people under 18 without medical guidance.
6. Medical disclaimer
The app is not a medical device. Fasting stages are general information, not medical advice. Talk to your doctor before fasting, especially if you are pregnant or breastfeeding, have diabetes or another medical condition, or take medication.
7. Your choices
- Turn notifications, the Live Activity and Apple Health on or off in the app's Settings or in iOS Settings.
- Delete your data by deleting the app.
- Manage or cancel your subscription in your App Store account settings.
If we change how the app handles data, we will update this page and the "Last updated" date above.
