Privacy Policy
Last updated: 28 August 2026
This policy applies to mobile apps published by Earthling Studio ("we", "us", "our apps"). Not every practice below applies to every app — each section says what it covers and only applies if your app actually uses that feature.
No account, no personal profile
Our apps do not require sign-in and do not ask for your name, email, or any personal profile information. Where an app stores content locally (such as reference data or your preferences), that data stays on your device and is not tied to your identity.
Analytics and crash reporting
Where an app uses them, we rely on Firebase Analytics and Firebase Crashlytics (Google) to understand how the app is used and to diagnose crashes. This can include device information, app version, general usage events (like which screens are opened), and crash logs. See Firebase's privacy policy.
Advertising
Where an app shows ads, they are served by Google AdMob. Depending on the consent choice you make when prompted, ads may be personalized (using an advertising identifier) or non-personalized. On iOS, personalized ads additionally require your permission under Apple's App Tracking Transparency framework — you can change this at any time in your device's Settings → Privacy & Security → Tracking. Apps that show ads also let you revisit your ad consent choice from within the app's own settings. See Google's advertising privacy policy.
Purchases
Where an app offers in-app purchases or subscriptions (for example, to remove ads), purchases are processed by Apple's App Store or Google Play, and purchase state is managed through RevenueCat, which receives an anonymous identifier and your purchase receipt to verify entitlement — no payment details (card numbers, etc.) ever pass through the app or RevenueCat. See RevenueCat's privacy policy.
Data sharing
Data described above, where collected, is shared only with the service providers named in this policy (Google/Firebase/AdMob, RevenueCat, and Apple/Google as the app store operator) to provide analytics, crash reporting, advertising, and purchase functionality. It is never sold.
Children
Our apps are not directed at children and do not knowingly collect data from children.
Changes to this policy
If this policy changes, the "Last updated" date above will be revised.
