No Face, No Name, No Number, No SIM card, No Internet! Berty is a messenger that doesn’t require any of your personal data or network connection (using Bluetooth Low Energy BLE). All conversations are encrypted with end-to-end encryption, in a fully distributed network.
It is a peer-to-peer messenger with no servers, no cloud - your data is only stored on the device where Berty is installed and used. No one would be able to access the data or shut the app down, not even the developers.
Being P2P, it means the IP address needs to be available to route messaging, but their site explains a bit about how they've tried to mask this. Whilst Briar is an excellent alternative, it is still Android only. The closest alternative is maybe Jami, but it lacks a non-Internet Bluetooth alternative if I recall correctly. Interestingly, Berty also can use Airdrop (iOS to iOS) and Android's Nearby as alternative protocols.
You can share your details and add contacts via a QR code, public key, or an invite link. It is currently available on both iOS and Android, with desktop clients to follow.
