LumiBlock Privacy Policy
Last updated: 12 November 2026
LumiBlock: Crystal Puzzle ("LumiBlock", "the game") is provided by Techone Digital. You can play offline without a LumiBlock account. Progress, settings and in-game items are stored on your device. To remove this local data, clear the app's storage or uninstall the game. LumiBlock is intended for players aged 13 and older and does not ask for or store a date of birth.
Rewarded advertising
You can choose to watch a video for an in-game reward. Ads are shown only when you ask for one and never interrupt a game. Videos are provided by Google AdMob, which may process IP addresses, approximate location inferred from IP addresses, app and ad interactions, diagnostics, and device or account identifiers to deliver and measure ads and prevent fraud.
iPhone: the game may ask permission to track you across other companies' apps and websites (App Tracking Transparency). If you choose "Ask App Not to Track", the advertising identifier is not used. Android: the app does not request the advertising ID permission.
Where required by law, a consent message appears before ads load. You can review your choices later under Ad privacy choices in Settings, when it is shown. The game plays the same whichever you choose.
Gameplay analytics
LumiBlock uses GameAnalytics to understand how the game performs and to improve it. It receives gameplay events such as session and level activity, scores, currency and item activity, rewarded video events, and purchase events. The SDK may process a generated identifier, IP address, and app and device information. You can turn off future analytics submissions in Settings under Anonymous stats. See GameAnalytics' Privacy Notice.
Purchases
Purchases are processed by Apple (App Store) on iPhone and by Google Play on Android. LumiBlock receives product and transaction information to deliver and restore purchases. We do not receive your card or payment details. Apple's and Google's own privacy policies explain how they handle that information.
Game Center and Google Play Games
Leaderboards and achievements are optional. On iPhone they use Apple Game Center; on Android they use Google Play Games. LumiBlock sends your scores and achievement progress to that service. Apple or Google handles sign-in and your profile, and leaderboard visibility follows your Game Center or Play Games settings. See Apple's Privacy Policy and Google's Privacy Policy.
What we do not do
- We do not require an account, email address or phone number to play.
- We do not sell your personal information.
- We do not run our own servers that store your game progress; there is no cloud save.
Your choices and requests
You can manage ad choices where shown and delete local data by clearing the app's storage or uninstalling. For requests about information associated with LumiBlock, contact us at the address below.
