NavSatCat — Privacy Policy
Wear OS navigation-satellite cataloguer · Last updated 1 September 2026, 12:31 EDT
What this application is for. NavSatCat is built for internal use, development and testing by Frost IT Solutions. It is not sold, not distributed publicly, and has no user base beyond its own developers — the data it reads is our own, from our own device. This policy is published openly alongside our other applications to meet Google's OAuth publishing requirements.
NavSatCat contains no analytics, no advertising, no tracking and no third-party SDKs. It transmits nothing, to anyone.
What NavSatCat reads
It is a diagnostic tool for the device's own satellite receiver. It registers for raw GNSS measurements and reports what the receiver is tracking:
- Per-satellite constellation, identifier and carrier frequency band
- Signal strength (C/N0) and baseband signal strength
- Pseudorange rate, accumulated delta range state and tracking state
- Receiver capability flags reported by the operating system
- Position fix accuracy and satellite count
The purpose is to establish what the hardware can do — which constellations and frequency bands it tracks, and whether carrier-phase measurements are usable. It is a hardware characterisation tool, not a navigation application.
Location
NavSatCat requests ACCESS_FINE_LOCATION and genuinely uses it.
Raw satellite measurements are only delivered while an active positioning
session is running, so the application requests location updates in order to
keep the receiver engaged.
It reports fix accuracy and satellite counts. It does not record or store coordinates, and it has nowhere to send them.
Where the data goes
Nowhere. Measurements are written to the Android system log on the device, where they can be read over a developer debugging connection by someone with physical access to the watch and developer mode enabled.
The application writes no files of its own, holds no network permission, and has no upload feature. The system log is a rotating buffer managed by the operating system, and its contents are overwritten as it fills.
Google account access
None. NavSatCat does not sign in to any account and does not use any Google API.
Retention and deletion
Nothing is retained by the application. The system log rotates on its own and is cleared on reboot; uninstalling the application leaves nothing behind.
