TECHNICAL AUDIT · ZERO-TRACKING
Zero-Tracking Privacy & Offline Architecture
Omitted Internet Permission
Unlike games that claim "offline mode" while continuing to run background syncs, nook games completely omits android.permission.INTERNET from its manifest. The operating system kernel enforces that zero network traffic can be generated.
On-Device localStorage Persistence
Game states, move histories, and unlocked achievements are saved directly with on-device localStorage persistence. Resumption takes under 16ms, allowing seamless task switching without memory loss.
Battery & Thermal Conservation
With no ad SDK bidding wars, analytics pings, or telemetry listeners, CPU cores sleep immediately after user input rendering. Plays for hours with virtually imperceptible battery impact.
