Effective date: 29 October 2026 · Last updated: 29 October 2026
PhaseBell ("the app", "we") is an interval timer. We designed it to collect as little as possible: no ads, no account and no tracking. Your workouts stay on your device.
1. Data stored on your device only
- Your workouts (names, phases, durations, colours, sound set), your workout history (start time, duration, rounds, pauses) and your settings (sounds, theme, language, privacy choices).
- A temporary audio file for a running workout.
- Nothing is synced and we keep no copy. Your own iOS or iCloud device backup may include it. Deleting the app deletes it; the History tab can be cleared at any time.
2. Data that leaves your device
| Data | When | Recipient and purpose |
|---|---|---|
| Purchase record for the optional Lifetime Premium (product, dates, receipt token), app version, device type, OS version, locale and currency, tied to a random anonymous ID generated on your device | When you buy or restore, and when the app re-checks Premium at launch | RevenueCat, Inc. (USA), purchase processor; Apple or Google (depending on your device) processes the payment. Used to unlock and restore Premium. |
| Crash reports: stack trace, device model, OS and app version, locale, free memory and disk, and a random installation ID | Only when the app crashes. Sent by default; you can switch this off in Settings → Privacy | Google Firebase Crashlytics. Used to find and fix crashes. |
| Usage events: onboarding completed, paywall viewed, purchase started, succeeded or failed, restore completed, workout completed (duration range only) with device and app metadata and the installation ID | Only if you agree on the consent screen or switch it on in Settings → Privacy (off by default) | Google Firebase Analytics. Used to learn which features are used. |
We do not collect your name, e-mail, phone number, contacts, photos, microphone input, location, health or fitness measurements, or advertising identifiers. The app shows no ads and does not track you across apps or websites, so there is no tracking prompt. Google may derive an approximate region from the connection's IP address when events are sent; ad personalization and Google Signals are disabled.
3. Permissions
- Background audio is used only so workout sounds keep playing with the screen locked; the app does not record audio.
- No microphone, camera, location, contacts or photos access.
4. Legal basis (GDPR / KVKK)
Purchase processing is necessary to provide the purchase you request (GDPR Art. 6(1)(b)). Crash reports are sent on the basis of our legitimate interest in keeping the app stable (Art. 6(1)(f)) and you can switch them off at any time. Usage events are sent only with your consent (Art. 6(1)(a)), which you can withdraw in Settings.
5. Retention
Data on your device stays until you delete it or the app. Purchase records are kept as long as needed to honour your lifetime purchase and for legal and accounting duties; you can request deletion of the anonymous record by e-mail (the purchase stays with your Apple ID or Google account). Firebase retains event data for the minimum period configured (2 months) and crash data for 90 days.
6. Your rights
- Access, rectification and erasure: your workouts are in the app; for purchase, crash or usage records write to us and we will act on it.
- Switch off crash reports and usage statistics at any time: Settings → Privacy.
- Complain to your data-protection authority (in Türkiye: KVKK Kurumu).
7. Children
The app is not directed at children under 13 and requests no personal data.
8. Not medical advice
PhaseBell is a timer. It gives no medical, fitness or training advice. Exercise within your limits and consult a professional if unsure.
9. Changes
We will post any change on this page and update the date above.
