Owlmakers ("the developer") respects the privacy of everyone who uses Data Usage ("the app"). This policy explains how the app handles information.
To show WiFi, mobile and tethering data usage and per-app usage, the app uses Android's Usage access (usage statistics) permission, which you turn on yourself in system settings.
Android requires location permission to show the connected WiFi name and nearby WiFi networks.
The following is stored only on your device and is not sent anywhere.
| Item | Details |
|---|---|
| Plan settings | Monthly data limit, tethering limit, cycle start day, alert percentage |
| Speed test history | Download/upload speed, latency, data used by the test, WiFi name |
| App settings | Theme, language, notification settings, apps excluded from stats |
Uninstalling the app deletes this information.
The speed test contacts M-Lab (Measurement Lab, a non-profit internet measurement project) public servers only when you tap Start.
The app shows a Google AdMob banner at the top of the screen to stay free.
The app collects anonymous usage statistics to learn which features are actually used.
The ongoing notification (current speed, today's usage) and limit alerts are created on the device. You can turn notifications off in settings.
This app uses Google's Firebase Cloud Messaging (FCM) to receive announcements and notices sent by the developer. When you open the app, Google assigns an FCM installation ID (registration token) to this installation; the app does not send or store this value on the developer's servers. The app subscribes to notification topics for the app name and your display language, and Google processes that subscription. A notification goes with the same content to every user of the same app and language and carries no personal data. On Android 13+ the notification permission is requested only when you tap the in-app notice line or the settings row, and you can use every other feature without allowing it. You can turn notifications off at any time in the device's Settings → Apps → Notifications, and you stop receiving them when you uninstall the app.
The app is not directed at children under 14 and does not knowingly collect children's personal information.
The app has no accounts or sign-up, so the developer keeps no personal information about you. You can delete everything on the device at any time by uninstalling the app.
