FairEmail
TAS Score: S3/3 — D5/5 — A3 / T2
Brief Description
Full-featured Android email client. No tracking, no ads, no cloud dependency. Works with any IMAP/POP3 provider. Privacy-focused with built-in encryption support (PGP, S/MIME).
Architectural Role
Client-side application layer — email. Connects to any standard email server. No proprietary backend.
Technical Autonomy
- Works without internet (cached emails available offline)
- Stores data locally (on-device database)
- Does not require external accounts (works with any email provider)
- Allows data export (standard email protocols — messages stay on server)
- Provides offline updates (F-Droid, GitHub APK)
