The short version
- No account, no sign-up, no ads and no tracking cookies.
- Your detections and location never leave your device.
- We count page views with cookie-free, privacy-friendly analytics (Vercel Web Analytics). It records only anonymous visit counts such as the page, country and browser type. It never receives your Bluetooth or location data.
- You can delete everything with one button.
What is stored, and why
| Data | Why | How long |
|---|---|---|
| Broadcast content and signal strength of tracker-type devices (AirTag/Find My, SmartTag, Tile, Chipolo), and the time | To recognise the same tracker again | Until you delete it. One-off passers-by are removed after 24 hours |
| Your position at each sighting, rounded to about 10 metres, and your route | To count different places | Until you delete it. The last 1,500 route points |
| Your settings | To remember your thresholds | Until cleared |
What is not collected
Your name, contacts, phone number, your phone's own Bluetooth address, the names of other Bluetooth devices, or anything from headphones, watches or TVs. Location is read only while a scan is running and stops when you stop scanning.
Storage and sharing
Data is saved in your browser's local storage on your phone or computer. We do not receive it. If you use Export, the file contains your location history, so keep it private.
Delete your data
Open the scanner, go to Settings → Delete everything. Clearing your browser's site data does the same.
