Effective Date: July 8, 2026
At LumaLattice, we are committed to protecting your privacy. This Privacy Policy describes how we collect, use, and process information when you use our mobile application (the "App").
We believe in data minimization. The App collects information under the following categories:
Device Information: We may collect generic, non-personally identifiable technical information (such as operating system version and basic device model) solely for analyzing system stability, crashes, and optimizing core application performance.
Local Storage Progress: All game data, including completed sudoku grids, challenge records, recipes, and observation notes, is stored entirely locally on your device. We do not upload your personal gaming progress to external cloud servers.
To help us maintain and improve system stability, you may be prompted to grant tracking authorization on your device. The information retrieved via this permission is restricted to diagnosing software crashes and optimizing the local app performance. We do not sell your personal data or tracking records to third-party ad brokers.
We do not sell, rent, trade, or otherwise transfer your personal data or usage details to external entities. Any collected device stability logs are shared only with analytics services that conform to industry privacy standards and are used exclusively to fix application defects.
Since your gameplay data is preserved strictly within your device's local database sandboxed sandbox, the security of your game progress is guaranteed by the iOS device security framework. We recommend keeping your system updated to ensure optimal local protection.
