Privacy policy

Last updated: 2026-10-13

This policy explains how the Block Street Cup app (developed by Nguyen Duc Thanh) handles your information. In short: we do not collect, sell or share your personal data.

1. Data stored on your device

So that you can keep your progress, the app stores the following on your device only: the display name you choose, your player colour, level, match stats, achievements and settings. This data is not sent to any server of ours.

2. Game Center / Google Play Games

If you choose to sign in to Game Center / Google Play Games, the sign-in is handled by Apple / Google. The app only receives your player ID and display name, to show them in the game, post scores to the leaderboard and unlock achievements. This data is processed under the privacy policy of Apple / Google. Signing in is optional — you can play the whole game without it.

3. In-app coin purchases

Coin packs are paid for with your App Store / Google Play account. We never receive or store your card details, payment account or identity; the app only receives a transaction ID so it can add the right number of coins once. Your coin balance and items are stored on your device.

4. What we don't do

• No account, email address or phone number is required.
• No ads, and no analytics or tracking tools.
• No access to your location, contacts, photos, microphone or camera.
• We do not sell or share your data with third parties.

5. Children

The app is suitable for all ages and does not knowingly collect personal information from anyone, including children. Coin purchases must be confirmed in your App Store / Google Play account; parents can restrict purchases in the device settings.

6. Deleting your data

You can delete all data stored on your device at any time in Profile › Delete data on this device, or by uninstalling the app. Game Center / Google Play Games data is managed in your Apple / Google account settings.

7. Changes to this policy

If this policy changes, we will update this page and the date above.
