Who we are
This policy covers Find Air Lite: Device Finder for Android (package app.web.devicefinder), published by developer Trung-Hieu Tran. Contact: trunghieu4121993@gmail.com.
Summary
Find Air Lite measures the Bluetooth signal of devices near you and shows it as a relative closeness percentage. Everything runs on your phone. There is no account and no Find Air server. Device names, Bluetooth addresses, saved devices and signal history never leave your phone. We use anonymous usage statistics and crash reports, which you can turn off, and the free app shows ads. We do not sell personal data.
Permissions we use
- Nearby devices (Bluetooth scan and connect): listening for Bluetooth signals around you, and starting pairing when you tap Pair device. On Android 12 and later the scan is declared as never used to derive your location.
- Location (Android 11 and earlier only): older Android versions require it before any Bluetooth scan. The app never reads, stores or uploads your location and never shows anything on a map.
- Vibration: the optional hot/cold haptic feedback while locating.
Data stored on your device
Devices you save (with any name you give them) and up to 24 hours of signal history, recorded only while the app is open, are kept in the app's private storage. Clear the history in Settings › Clear signal history, remove a saved device in the app, or uninstall the app to remove all of it.
Analytics and crash reports
The app uses Google Firebase Analytics and Firebase Crashlytics to count anonymous events, such as a scan started, a device located, the Pro screen shown or a purchase completed, and to report crashes. These events contain only device types and numbers — never device names, Bluetooth addresses or location. You can turn both off at any time in Settings › Share usage statistics.
Ads
The free version shows occasional full-screen ads from Google AdMob, with Unity Ads as a fallback. The first time you open the app it asks whether ads may be personalised, and you can change that answer under Settings › Personalised ads. Google and Unity may collect device identifiers, including the advertising identifier, and data about how you interact with ads, as described in Google's policy and Unity's privacy policy. Find Air Pro removes ads.
Purchases
Purchases are processed by Google Play. We receive only the purchase status needed to unlock Pro, never your payment details.

Children
The app is not directed to children under 13, and we do not knowingly collect data from children.
