Police Rank Up Privacy Policy

Effective date: August 26, 2026

1. Overview

Police Rank Up (the "App") is provided by Zero One Studio. This policy explains what information the App handles and how.

2. Information we collect

Advertising identifiers — To serve ads and manage their frequency, advertising identifiers (IDFA / Ad ID) and coarse device information may be shared with ad providers. Apps that request iOS App Tracking Transparency use the identifier for ad personalization only if you allow it; apps that do not request it show non-personalized ads only.
Account identifiers — We store an account identifier needed to provide the service. If you use social sign-in, we receive an identifier and email address from that provider.
User-entered content — Content you enter in the app (lists, records, nicknames, etc.) is stored to provide app features.
Purchase history — We check purchase history to process payments and restore purchases. Payment details such as card numbers are handled by the App Store / Google Play and are never stored by the studio.
Device info · push tokens — We store your device model and push token to deliver push notifications and refresh widgets.

Game progress (ranks, board, currencies, records) is stored on your device and automatically backed up to the cloud (Supabase, Seoul region) in case you change or reinstall your device. The backup starts with an anonymous guest account created by the app, with no email or name; if you choose, you can link it to your Google account in Settings (we then receive the account identifier and email Google provides). Settings → Delete account removes your cloud account and save immediately. Google AdMob processes the advertising identifier and device information to show ads. Payments are handled by Google Play; the app keeps only transaction IDs in the save to prevent double grants — the studio never receives card or other payment details. The app is not directed at children under 13 (store target age 13+).

3. How we use it

Collected information is used only to provide app features, diagnose errors, and serve ads. We do not profile users for identification and never sell data to third parties.

4. Third-party services

The App uses the services below; each service's own privacy policy also applies.

Google AdMob
Supabase
Google Sign-In
Google Play billing

About ads

The App shows ads through Google AdMob. Ad providers may use advertising identifiers to show relevant ads. On iOS, the advertising identifier is used only if you allow the tracking permission the App requests; declining does not limit your use of the App.

You can turn off ad personalization or reset your advertising identifier in your device settings. Google's ad policies are available at policies.google.com/technologies/ads.

Retention and deletion

Data stored on your device is deleted when you delete the App. To request deletion of data stored on our servers, contact us at the email below.

Children's privacy

The App is not directed at children under 14 and does not knowingly collect personal information from children.
