About the app
PeakPing is an Android app that displays real-time GPS elevation and accuracy data. The source code is available under the GPLv3 license.
What data is processed?
Location data (GPS)
PeakPing requests access to your precise location (ACCESS_FINE_LOCATION). The app reads exclusively from your device’s hardware GPS chip, no wifi- or mobile network-based location is used. The following data is processed:
- Latitude and longitude
- Altitude above sea level
- Horizontal and vertical accuracy
- Number of GPS satellites used
All this data stays locally on your device. It is not sent to the developer or any external server.
Barometer sensor
If your device has a barometer sensor, the app reads atmospheric pressure to provide smoother altitude readings between GPS fixes. This data is only processed in memory and is never stored or
transmitted.
Reverse geocoding (place name)
To display a place name (“City, Country”) alongside your location, the app uses Android’s built-in Geocoder API. This API may use Google’s geocoding servers. Please refer to https://policies.google.com/privacy for more information on how Google processes this data.
Saved locations (pins)
When you save a location, the following data is stored locally in your device’s app storage (SharedPreferences):
- Latitude and longitude
- Elevation
- Place name
- Timestamp of saving
- Your chosen label
This data does not leave your device. You can delete saved locations at any time from within the app. App settings Your theme preference (dark/light/system) and unit system (metric/imperial) are stored locally in SharedPreferences. No other settings are tracked.

- The app does not transmit location or sensor data to the developer
- The app contains no advertisements
- The app contains no third-party analytics or crash reporting
- The app does not use cookies or tracking technologies
- The app does not create accounts and does not require registration
