Privacy Policy (TimerCoach)

1. What We Collect (and What We Don’t)

Data TimerCoach does not ask you for

TimerCoach does not ask for your name, email address, phone number, precise location, or advertising identifier (IDFA) in the app. Usage data is not linked to a TimerCoach account and is not used to track you across apps or websites.

Usage analytics (TelemetryDeck)

TimerCoach sends usage events to TelemetryDeck to help improve the app. In its default mode, the SDK creates a pseudonymous identifier for this app installation and hashes it on the device before transmission. It remains recognizable for that installation but does not contain your name or a TimerCoach account ID. Apple classifies this as “Device ID” used for analytics.

Analytics may include:

• The pseudonymous, hashed identifier for this app installation
• App events/actions defined by us (e.g., “Timer Started”, “Settings Opened”)
• A timestamp rounded to the nearest hour
• Device metadata such as operating system, app and build versions, and device type
• Limited event values such as fixed workout categories, interval and round counts, coarse duration/progress values, and technical status or error messages; not workout names, heart rate, calories, Spotify playlist URIs, or Spotify access tokens

IP addresses: TelemetryDeck states that IP addresses are never stored on TelemetryDeck servers (neither in the database nor in log files).

Retention: TelemetryDeck’s current Privacy FAQ says active retention depends on the plan. Events may then be moved to cold storage. TelemetryDeck currently has no fixed deletion schedule for cold-storage events; it expects deletion after 7 to 10 years but does not guarantee a date. See TelemetryDeck’s Privacy FAQ.

2. Local Data Storage

Custom workouts, settings, and regular workout history are stored locally in the app and are not synchronized to TimerCoach servers. Delete workout history in Settings using “Reset Statistics”; delete custom workout templates from the workout list. This does not delete records in Apple Health. Spotify access tokens are stored separately in the iOS Keychain.

3. HealthKit and Apple Health

If you select an Apple workout activity for a workout and grant HealthKit permission, TimerCoach can start a matching workout session on your paired Apple Watch. Apple Health can save the completed workout. During the workout, TimerCoach may read heart rate and active calories from HealthKit and display them live on Apple Watch and iPhone. Without a selected activity or permission, the interval timer continues to work; Health recording and live values may be unavailable.

TimerCoach does not save heart rate or calorie summaries in its workout history, or send HealthKit values to TelemetryDeck, Spotify, or TimerCoach servers. Manage permissions in Apple’s Health app. Delete Health records separately in Apple Health; resetting TimerCoach statistics does not delete them.

4. Camera Use (Camera Mirror)

TimerCoach requests access to your device’s camera only for the Smart Overlay feature (for visual self-observation of your form during workouts).

• On-device processing: the camera feed is processed in real time on your device
• No recording: no video or images are recorded, saved, or transmitted
• No third-party access: camera data is not shared with third parties

5. Third-Party Services

Spotify (optional and experimental): The integration is off by default. To reveal it, tap the “Settings” title seven times in quick succession. Then open “Music” and enable Spotify control. If you connect Spotify, you authorize the connection with Spotify. TimerCoach can read your playlists so you can choose one for a workout; the selected playlist URI is stored locally with that workout template. The Spotify access token is stored in the iOS Keychain. Turning the integration off stops its use but does not automatically delete the token. You can revoke access in your Spotify account settings; if Spotify rejects the token as invalid, TimerCoach deletes it from Keychain. Spotify processes the connection under its Privacy Policy. The timer works without Spotify.

TelemetryDeck receives the pseudonymous analytics described above. See TelemetryDeck’s privacy information.

6. When You Contact Us

If you contact us by email, we will process the information you provide (e.g., your email address and message content) solely to respond to your request and provide support.

7. Children’s Privacy

TimerCoach is not directed to children under the age of 13. We do not knowingly collect personal information from children.

8. Changes to This Privacy Policy

We may update this Privacy Policy from time to time. We will post the updated policy on this page and update the “Last updated” date.
