CalyxOS

TAS Score: S3/3 — D4/5 — A3 / T2 D4 not D5: microG provides partial Google compatibility — some telemetry possible (Q4).

Brief Description

Privacy-focused Android OS with microG for basic Google service compatibility. Easier transition from stock Android than GrapheneOS — F-Droid and Aurora Store pre-installed. Supports Pixel and select Fairphone/Motorola devices.

Architectural Role

Base operating system layer — mobile. Includes microG for push notifications and location services without full Google Play Services.

Technical Autonomy

  • Stores data locally (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)
