Ergmate: privacy
Last updated 7 October 2026
Ergmate connects to the Bluetooth monitor of a rowing machine and records your workouts. It is a small Android app I build on my own
(com.growingpeas.rowing on Google Play). This page says what it keeps, what leaves
your phone, and why it asks for each permission. The controller is Lawrenza SRL,
trading as Growing Peas; full details are on the legal notice.
What leaves your phone
- Nothing, unless you export a workout yourself. There is no server to send it to.
- Purchases. The Pro upgrade is a one-time purchase handled by Google Play. Google processes the payment under its own privacy policy; I receive no card details, only the order record Google shares with every developer (order number, product, price and country).
There is no account, no sign-in, no analytics, no advertising, no crash reporting and no server of mine. The app contains no third-party tracking code.
What stays on your phone
- Your workouts: time, distance, stroke rate, power, calories, splits and stroke-by-stroke data.
- Heart rate, when your monitor or chest strap provides it. It is fitness data and it stays on the phone.
- TCX and CSV files you export (Pro) are handed to the app you pick in the Android share sheet; what happens next is up to that app.
Android cloud backup is switched off for this app. If you move to a new phone with Android's device-to-device transfer, your workouts come along; nothing is sent to your Google account.
Permissions
- Nearby devices (Bluetooth): to connect to the rowing monitor; declared as never used to find your location.
- Notifications and foreground service: keeps the connection to the monitor alive if you switch apps during a workout; stop it from the notification.
- Internet: used only by Google Play for the purchase.
The app never asks for your location, your contacts or your files.
Limits of use
Heart-rate figures and zones are a training guide, not medical advice. Ergmate is not a medical device. It is not affiliated with or endorsed by Concept2.
Deleting your data
Everything is on your phone, so you delete it there: in the app, or with Settings, Apps, Ergmate, Storage, Clear storage, or by uninstalling. I hold no copy to delete. Files you exported or shared stay where you put them.
Children
The app is not directed at children under 13.
