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. Gameplay does not require an internet connection. Opening the support website, full online privacy policy or Apple licence link, and sending support email, require connectivity.
Product-specific notice
Last updated:
This notice describes Lumizig, 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.
Scores and settings remain in local app preferences until the app’s data is removed. On iPhone or iPad, use Delete App rather than Offload App to remove the installed app and its local data. Offloading may retain app data. Backups may retain older copies or restore records; manage those copies using your device and backup settings. The developer has no server copy of your scores or settings and cannot remotely delete records on your device.
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.
We retain support emails and their attachments for up to 12 months after an enquiry is closed, then delete them from our active support records. We may retain information longer where required by law. Any retained information is limited to that purpose.
To request deletion of information you have sent to support, or to withdraw permission for further optional use of it, email help@ahmedhamed.com with the subject “Lumizig privacy request”. Please use the address you originally contacted us from where possible and identify the enquiry. Do not send passwords or identity documents. We may ask for minimal information needed to verify the request. Deletion does not undo replies already sent or remove copies you hold yourself. You can continue playing without contacting support or sharing personal information.
This notice should be updated if the app’s features or data practices change. The current version will be published with its revision date.
