SimpleX Chat
What it's for
An encrypted messenger with no account, no number and no identifier. You connect by sharing a link or QR code.
Why it matters
By design, even the servers can’t know who talks to whom. It’s currently the strongest option against metadata correlation.
For whom & when
Pseudonymous accounts, sensitive contacts, high-risk. A bit younger than Signal, with a few rough edges.
Install & use
Install from simplex.chat (F-Droid, Google Play, App Store or APK).
Pick a local display name (never your real name: it stays on your device).
To add a contact, share a one-time invitation link or a QR code.
- Turn on the passcode lock, and (advanced) configure your own SMP servers.
