OneTrail is a single-player puzzle game. This policy explains, in plain language, what happens to your data when you use the app.
OneTrail itself does not collect any personal data. There are no accounts and no analytics. The app shows ads between levels through Google AdMob, which — like almost every ad network — uses a device advertising identifier to serve and measure those ads. See "Advertising" below for details.
The app saves two small pieces of information directly on your device, using the operating system's standard local storage (never sent anywhere):
That's the entire footprint OneTrail's own code creates. Nothing else is read, recorded, or stored by the app itself.
OneTrail shows interstitial ads between levels (never during a puzzle, and never more than one every 90 seconds) through Google AdMob. OneTrail does not request tracking permission and does not access your device's advertising identifier, so ads are served on a non-personalized, contextual basis. To serve and measure these ads, AdMob may still collect general technical data such as device type, OS version, and approximate (IP-based) region.
This data is collected by Google, not by OneTrail directly, and is governed by Google's Privacy Policy. OneTrail contains no other third-party SDKs, analytics, or trackers.
OneTrail contains no user-generated content, chat, or in-app purchases, and OneTrail's own code collects no personal data from anyone, including children. If your app listing targets children, configure AdMob's child-directed treatment / ad content settings accordingly in your AdMob account.
If this policy ever changes, the update will be posted on this page with a revised date above.
