Privacy Policy
Last updated: 2026
Shadow Grid ("the app") is developed by Lê Đình Phúc. This policy explains what data the app collects and how it's used.
Data we collect
- Anonymous account identifier. The app creates an anonymous Firebase Authentication identity to support the leaderboard feature. No email, phone number, or real name is required or collected.
- Leaderboard data. If you set a username and avatar, that username, avatar choice, and your level-completion score are stored and shown publicly on the in-app leaderboard.
- Advertising data. The app shows ads via Google AdMob, which may collect device identifiers (such as the IDFA, subject to your App Tracking Transparency choice) and usage data to serve and measure ads. See Google's privacy policy for details: policies.google.com/privacy.
- Purchase data. In-app purchases (such as Remove Ads) are processed entirely by Apple's App Store / StoreKit. We do not receive or store your payment details.
Data we don't collect
We don't collect your name, contact details, or precise location, and we don't require account sign-up.
Data deletion
To delete your leaderboard entry or ask about any data associated with your anonymous ID, email us at edwardlauv@gmail.com.
Children's privacy
Shadow Grid does not knowingly collect personal information from children beyond the anonymous, non-identifying data described above.
