TV Size Distance Calculator (“the app”) works out the best viewing distance for a screen size, or the screen size for a viewing distance, for 720p, 1080p, 4K and 8K, with screen dimensions, viewing angle and a room diagram. This policy explains what the app does with data.
The sizes and distances you enter are calculated on your device. The app stores only your preferences — language, resolution and unit system — and keeps no history. Your unit system is suggested from your device’s region setting, not from your location.
If Android backup is turned on for your Google account, Android may include the app’s stored data in that backup. You can turn backup off in Android settings.
Advertising. The app shows banner and full-screen ads from Google AdMob, with Meta Audience Network as a mediation partner. To select and measure ads, these providers may collect your device’s advertising ID, your IP address and the approximate location it implies, and device, app and ad-interaction information. In the European Economic Area, the United Kingdom and other regions where it is required, the app asks for your choice through Google’s User Messaging Platform before any ad is requested, and you can change it at any time from Privacy options in the app, which appears where it is required.

Analytics. The app uses Google Analytics for Firebase to see which features are used. Events record which calculation ran, the resolution, the unit system, and the screen size or distance rounded into a broad range (for example “55–64 inches”) — never the exact value you typed. Firebase also records some information automatically: an app-instance identifier, the device model, the operating-system and app versions, the app language, and an approximate country derived from your IP address, along with standard events such as the first open and the start of a session.
Crash reporting. Firebase Crashlytics receives a report when the app crashes: the error and stack trace, the device model, the operating-system and app versions, and an installation identifier.
Notifications. The app can receive occasional announcements through Firebase
Cloud Messaging. Android asks for notification permission after your first calculation in a session. If you allow notifications, the app subscribes this installation to a
general topic (all_users), and messages go to everyone subscribed to it — the
app does not target individual devices. Firebase may register a messaging token for the
installation; the token identifies the installation, not you. Turning notifications off in Android settings stops them.
The app is not directed at children under 13 and does not knowingly collect personal information from them.
