What we actually store about you
No marketing pitch — this is the full inventory of everything Trail-Safe puts in its database when you use the watch app and the dashboard. If it isn't on this list, we don't have it.
Google account
- Google subject ID (the stable
sub) - E-mail address
- Display name (first + last)
From Google Sign-In so we know which account a fix belongs to.
Location fixes
- Latitude, longitude, altitude, accuracy
- Timestamp (UTC)
- Optional heart rate (bpm)
- Session ID grouping fixes into one trail
So we can draw your route on the map.
Watch metadata
- Device model (e.g.
Pixel Watch 2) - Random device + session identifiers
- Heartbeat "ping" frames (no coordinates)
So the dashboard knows whether your watch is currently online.
SOS signals
- SOS flag
- Last known position at the moment SOS was raised
So your contacts can see where you triggered SOS from.
Subscription state
- Google Play purchase token (server-side only)
- Current entitlement (plan, expiry)
- Real-Time Developer Notification events from Play
So premium features unlock for the right account. We never see your card number — Google handles payment.
Operational logs
- Request counts, error traces, latency
- Source IP (rotated after 30 days)
So we can keep the service up and fix bugs.
