Stridenome Privacy Policy
Effective date: October 28, 2026
Stridenome is a cadence metronome for runners. It is made by an independent developer. This policy says what the app does with your data.
Short version: Stridenome does not collect your data. It has no accounts, no ads, no analytics and no tracking. It does not send your data to me or to any other company. The app keeps its data on your device.
Distance, pace and timing are estimates
Stridenome measures distance and time from the sensors in your iPhone. These values are approximations. They can be wrong.
- GPS distance. The app adds the distance between GPS location readings. It ignores readings that are not accurate (worse than about 20 meters) and readings that imply an impossible speed. Buildings, trees, tunnels and weak signal can make the distance too long or too short.
- Pedometer distance. If GPS is not available, or if you turn off Precise Location, the app uses the step-based distance from your iPhone's motion sensors. This is less accurate, and it depends on your stride.
- Time and pace. The app uses your iPhone's clock. Time that you pause is not counted. Pace comes from the measured distance and time, so it has the same error as the distance.
- Run Together. The two phones estimate the difference between their clocks. The start and the Run/Walk switches can differ by a small amount.
- Cadence. The click plays at the tempo that you choose. The measured cadence comes from your step count and is also an estimate.
Do not use Stridenome for medical, safety, race-timing or training decisions that need exact numbers. It is not a medical device. It does not give medical advice.
Data the app uses
| Data | Why the app uses it | Where it goes |
|---|---|---|
| Location (precise, only while you run) | To measure distance for announcements and your run log | Stays on your device. The app does not store your route. It keeps only the distance. |
| Motion & Fitness data (pedometer) | To measure distance when GPS is not available | Stays on your device |
| Apple Health: step count and height (read only, with your permission) | To show your measured cadence and to suggest a starting cadence | Stays on your device. The app never writes to Health. |
| Run log (dates, tempo, distance, pace, preset names, and a partner's name if you used Run Together) | To show your history | Stored on your device only |
| Settings and presets | To remember your choices | Stored on your device only |
The app asks for each permission when it needs it. You can say no. The app still works. For example, if you refuse location, it uses the pedometer.
Run Together
Run Together links two phones that are near each other. It uses your local network (Wi-Fi or peer-to-peer) and Bonjour. The phones send each other only a runner name, the app build number, the tempo and interval settings, and start and timing messages. This data goes directly between the two phones. It does not go to a server. The app stores your partner's name in your run log.
Health data
The app reads Health data only to run its features. It never uses Health data for advertising, marketing or data mining. It does not share Health data with anyone. It does not store Health data in iCloud.
Sharing, tracking and third parties
The app has no third-party code that collects data. It does not share your data with anyone. It does not track you across other apps or websites.
Keeping and deleting your data
The app keeps your data on your device until you delete it. To remove the data, delete the app. This removes the run log, presets and settings. You can change or remove each permission at any time in iOS Settings (Privacy & Security, and the Health app).
Children
Stridenome is not directed at children under 13. It does not collect data from anyone.
Changes
If this policy changes, I will update this page and the effective date.
