This Privacy Policy describes how we collect, use, store, and share information when you use the Google Play edition of Brain Training Challenge. This edition is separate from our China TapTap edition and uses different servers and account systems.

1. Summary

We do not require TapTap login or a social account to play.
We create a guest device account so cloud save and leaderboards can work.
Game data for this edition is stored on our overseas API at api.triworklab.com (separate from our China servers).
Rewarded ads (Google AdMob) may be offered; when enabled, Google’s ad SDK and consent tools apply.
Optional Sign in with Google may be added in a future update to restore progress on a new device.

2. Information we collect

2.1 Guest device account & game services

To provide cloud save, leaderboards, visit profiles (outfit / training-room snapshots), and abuse protection, we process:

A pseudonymous device identifier generated and stored on your device (not your raw hardware serial).
A server-side account id and display nickname you choose in-game.
Gameplay and progress data (scores, ranks, settings, wardrobe ownership, daily progress, boss clears, etc.) stored as game save data.
Leaderboard entries (score, nickname, equipped cosmetics metadata).
Visit/home layout metadata you choose to publish (cosmetic ids and layout numbers — not private photos).
Basic technical data: app version, platform, IP address, request timestamps, and error logs for security and reliability.

Legal bases (EEA/UK where applicable): performance of the game service you request; legitimate interests in securing and operating online features.

2.2 Advertising (when enabled)

If you watch a rewarded ad, Google AdMob may process:

Advertising ID (GAID) where available
Device and app information, IP address, ad interaction data

In the European Economic Area, the United Kingdom, and other regions where required, we use Google’s User Messaging Platform (UMP) to collect or record ad consent before serving personalized ads.

Google’s privacy information: Google Privacy Policy, AdMob & user data.

2.3 Optional Google Sign-In (future)

If you choose to sign in with Google in a future version, we may receive your Google account id, email (if shared by Google), and display name to link your guest progress to a recoverable account. Sign-in will remain optional.

2.4 What we do not collect in this edition

No TapTap login, real-name anti-addiction flow, or TapTap cloud save
No precise GPS location
No access to contacts, SMS, call logs, or photo library for core gameplay

5. Storage, retention & location

Guest account and save data for this edition are stored on servers in Ireland (AWS eu-west-1) where possible. We retain data while your account is active and as needed to operate leaderboards and prevent abuse, then delete or anonymize when no longer required unless law requires longer retention.

6. Sharing

We do not sell your personal information. We share data only with service providers listed above, when required by law, or to protect users and our service.

Leaderboards and visit features show information you choose to make visible (nickname, scores, equipped cosmetics, room layout).

7. Your choices & rights

Delete local data: clear app storage or uninstall the app on your device.
Request cloud deletion: email us with your in-game nickname and approximate registration time; we will verify and delete guest cloud data where feasible.
Advertising: reset or limit your advertising ID in Android settings; use UMP consent choices when shown.
EEA/UK rights: access, rectification, erasure, restriction, portability, and objection — contact us at the email below. You may lodge a complaint with your local supervisory authority.

8. Children

The game offers age-based difficulty bands but is directed to a general audience 13+ on Google Play and is not designed primarily for children under 13. If you believe a child under 13 provided personal information without parental consent, contact us and we will delete it.

9. Security

We use HTTPS for API traffic, access controls on servers, and pseudonymous identifiers instead of raw device hardware ids where possible.

10. International transfers

If you use the app outside the EU, your information may be processed in Ireland and other countries where our providers operate, with appropriate safeguards where required.

11. Changes

We may update this policy. Material changes will be reflected by updating the date above. Continued use after changes means you accept the updated policy.
