DeepyChat uses the Signal Protocol so your messages are encrypted on your device before they reach our servers. We cannot read them. Nobody can.
Why DeepyChat
Every architectural decision was made to minimise what we know about you.
Double Ratchet + X3DH. Your private keys never leave your device. Messages are encrypted before they're sent.
We store ciphertext blobs and conversation IDs — nothing that reveals who said what, when, or how often.
Set any conversation to auto-delete. Timers run client-side — expiry is enforced even if you're offline.
Sender keys mean group messages are as fast as 1:1. Every member's device holds their own decryption keys.
Attachments are encrypted client-side before upload. Files are stored in R2 as opaque blobs — unreadable without your key.
Join via personal invite links. No phone number required. No account recovery means no backdoor into your messages.
Your password is never stored in plaintext. Keys are generated on your device.
