Read the bend. Keep the glow.
Lumizig is a single-player maze runner. Choose Easy, Medium or Hard, then start a run. Your runner moves automatically. Swipe or tap an arrow to queue a direction; the runner turns when an opening permits it. Collect crystals for bonus points and avoid the walls.
Include your device model, operating system, app version/build, difficulty and what happened. A screenshot or short recording may help, but remove personal or unrelated information before sending it. Never send passwords or account credentials. No game account is needed.
Quick answers
Check Crystal sound in Settings, your device volume and Silent Mode. Use Preview chime to test it.
Switching apps, opening Settings or changing the screen size can pause a run. Choose Keep running when ready.
Completed-run personal bests are saved on the device, separately for each difficulty. They are not an online leaderboard and do not sync through a game account. An unfinished run is not restored after the app is terminated.
Yes. The optional Apple licence link requires an internet connection, but gameplay does not.
Product-specific notice
Last updated:
Lumizig version 1.0
This notice describes Lumizig version 1.0, the offline arcade maze game published by Ahmed Hamed. It describes the game separately from the Industrial Technology Study Studio website.
Lumizig does not collect or transmit personal information to the developer through the game. It requires no account and includes no advertising, tracking, analytics, in-app purchases, hosted gameplay service or runtime AI service.
The app saves the selected difficulty, the completed-run personal best for each difficulty and the crystal sound preference in local app preferences. A small migration flag preserves score records from earlier versions. The game does not send these records to a server or provide its own cloud synchronisation. An unfinished run is not saved across app termination. Device backups or restoration may affect local records under the operating system’s controls.
The crystal collection sound is generated locally. The app does not record audio or request access to the microphone, contacts, photos or location.
The operating system, App Store, device backups and diagnostics operate under Apple’s terms and your device settings. The optional Standard EULA link opens Apple’s website, whose privacy practices apply there. The game does not transfer your score or settings through that link. Website hosting and email services may process ordinary connection or security information when you visit this website or contact support; that is separate from in-game collection.
If you voluntarily email help@ahmedhamed.com, your email address and the information you include are used to respond to the enquiry. Please send only information needed to explain the problem. To ask about information you have sent to support, contact the same address. This support correspondence is separate from data handled by the installed game.
This notice should be updated if the app’s features or data practices change. The current version will be published with its revision date.
