GrapheneOS

TAS Score: S3/3 — D4/5 — A3 / T2 D4 not D5: limited to Pixel devices only (Q8 — hardware dependency).

Brief Description

Hardened Android-based mobile OS focused on privacy and security. No Google services by default — optional sandboxed Google Play available for app compatibility. Verified boot, hardened memory allocator, network and sensor permissions per-app.

Architectural Role

Base operating system layer — mobile. Foundation for the entire mobile autonomous stack.

Technical Autonomy

  • Works without internet (fully functional offline)
  • Stores data locally (everything on-device, encrypted)
  • Does not require external accounts (no Google account needed)
  • Allows data export (standard Android backup, file access)
  • Provides offline updates (OTA or sideload)
