Trust Center
Your data, in plain English.
Detectorists guard their spots. So here is exactly what SweepTrack stores, what stays on your phone, what leaves it and why, and what you control. No policy fog.
On your device first
Your sessions, finds, and their locations live on your phone, not on our servers.
No ads, no ad trackers
No advertising, no third-party advertising trackers, and we never sell your data.
Diagnostics are opt-in
Crash and usage diagnostics are off by default, anonymized, and coordinate-scrubbed when you turn them on.
Backups only you can open
A backup writes to your own Google Drive, which the app can't read. Add a passphrase and it's AES-256 encrypted on your phone before it uploads.
Where every piece of data goes.
One row per feature. If a row says data leaves your phone, it says exactly where and why.
| Feature | Data used | Where it's stored | Shared with | Retention | Your control |
|---|---|---|---|---|---|
| Sessions & GPS tracks | Your location and the path you walk | On your device (plus your Google Drive if you turn on backup) | No one; a Drive backup lives in your own account | Until you delete it | Export or delete anytime |
| Finds, photos, video, audio | The find details and media you log | On your device (plus backup) | No one | Until you delete it | Edit, delete, or export |
| Radar live group | Your live position, only while you're in a group with the app open | A temporary group on our server | Only people who joined with your code | The group expires in about 12 hours; your entry is removed the moment you leave | Leave, or pause sharing with ghost mode |
| Radar saved spots | Coordinates you save for yourself | On your device only | No one | Until you delete them | Private to you, never shared |
| Map overlays | The map images you import | On your device (plus backup) | No one | Until you delete them | Delete anytime |
| Weather, tide & forecast | An approximate location, per request | Not stored by us | The weather provider (Open-Meteo) and NOAA for tides, to return the forecast | Per request | Skip the forecast and tide tools to send nothing |
| Diagnostics (optional) | Anonymized, coordinate-scrubbed crash and usage data | Off until you turn it on | The diagnostics provider, without your identity | Per the provider's policy | Stays off by default; toggle in Settings |
| Billing | None for the core app; purchases go through Google Play | Per Google's policy | Manage in Google Play |
What the Google Play labels mean.
The app's Google Play listing carries a Data safety section because a few features send data off your phone by design. Radar shares your live position with the group you join. The forecast and tide tools ask a weather provider for data by location. Optional diagnostics, when you switch them on, send anonymized crash and usage data.
That is the whole of it. Your finds and their locations stay on your device, nothing is sold, and nothing feeds advertising. If a Play label looks broader than what you read here, it is covering those specific, optional flows.
You're in control.
Export your data to GPX, KML, CSV, or JSON anytime. Delete any session, find, waypoint, or overlay. Leave a Radar group with one tap. Keep diagnostics off for good.
