LUMIS (the game and this website, lumisgalaxy.com) is created and operated by Giga Sher, an independent developer based in Tbilisi, Georgia.
This website does not collect, store or transmit any personal data. Mini-game scores and your language preference are saved only locally in your own browser (localStorage) and never leave your device. We use no tracking cookies, no analytics and no advertising.
The LUMIS mobile game is available on Google Play and the App Store. It is free to play, has no accounts and no sign-in: your progress โ levels, scores, upgrades and settings โ is stored only on your own device. We run no servers of our own, so we never receive, see or store your personal data.
The game is supported by advertising served through Google AdMob (rewarded and interstitial ads). To deliver, cap and measure those ads, Google may process your device's advertising identifier โ the Advertising ID on Android, the IDFA on iOS โ along with technical information such as device model, approximate region and how an ad was interacted with. How Google handles this is described in Google's Privacy Policy (policies.google.com/privacy). We do not sell, share or transfer user data to anyone else.
On iPhone and iPad the game asks for your permission through Apple's App Tracking Transparency prompt before that identifier may be used for tracking. If you decline, the game remains fully playable and you still see ads โ they are simply not personalised. You can change your answer at any time in Settings โบ Privacy & Security โบ Tracking.
In the European Economic Area, the United Kingdom and Switzerland, a consent dialog from Google's User Messaging Platform appears before any ad loads, and your choice there decides whether personalised ads may be shown.
The Android version includes the RevenueCat SDK, which keeps track of whether a purchase has been made. When it runs it creates an anonymous identifier for that installation and contacts RevenueCat's servers; it never receives your name, email address or payment details โ payment is handled entirely by Google Play. The iOS version has no in-app purchases and does not use this SDK. In-game unlocks are earned by watching a rewarded ad instead.
LUMIS is not directed at young children, and the age rating shown on each store listing applies. We do not knowingly collect any data from children โ in fact we collect no personal data from anyone. If you are a parent or guardian with a question about this, please write to us.
You can reset or delete your advertising identifier at any time: on Android in Settings โบ Google โบ Ads, and on iOS in Settings โบ Privacy & Security โบ Tracking.
Because every piece of game data lives on your own device, uninstalling the game removes all of it completely. There is nothing held on our side for us to hand over or erase.
