Privacy Policy
Princess Underground (Maybe)
Last updated: October 12, 2026. If this English version and the Japanese version differ, the Japanese version prevails.
1. Information stored in the app
The app saves your game records (the name you enter, score, depth reached, play date and number of revives) only on your device. This information is never sent to the developer's servers. Deleting the app also deletes your records.
2. Advertising
The app uses Google AdMob, an advertising service provided by Google LLC. To serve ads, measure their performance and prevent fraud, Google may collect and use the following information:
- Advertising identifier (IDFA), only if you allow "Allow Apps to Request to Track"
- Device information such as IP address, device model and iOS version
- Ad interactions such as views and taps, and approximate location (estimated from your IP address)
You can choose whether to allow tracking on the prompt shown the first time you open the app. To change it later, go to Settings → Privacy & Security → Tracking. Even if you don't allow tracking, all features of the app remain available (the ads you see may differ).
For how Google handles this information, see:
3. Your choices in US states with privacy laws
If you are in a US state with a consumer privacy law (such as California), you can opt out of the "sale" or "sharing" of your personal information for interest-based advertising. Tap "Privacy settings" on the title screen and choose "Don't sell or share my data". You can change this choice at any time from the same button.
4. Co-op play (communication with nearby devices)
Co-op play uses Apple's MultipeerConnectivity to communicate directly with nearby devices over Wi-Fi and Bluetooth. Only the name you enter and the information needed to play (such as character positions and gold changes) is exchanged. It never goes through a server on the internet, and the developer does not receive this information.
5. Sharing with third parties
The developer does not sell, provide or disclose your information to third parties (except for the collection by the advertising service described in section 2).
6. Changes to this policy
This policy may be updated when necessary. Changes take effect when they are posted on this page.
