Encrypted mail and chat, from Tor Browser
Private.Ki runs its own onion service. Open it in Tor Browser and the connection stays inside the Tor network the whole way, which hides your network address from us.

Read it character by character the first time, then keep it as a bookmark. An address that differs by a single letter is a different service run by someone else.
Encryption first. With or without Tor, every mail between Private.Ki users, every chat and every group is encrypted end to end on your device. No one can read it, including us.* How the encryption works →
At a glance
What Private.Ki hides on its own
- Message bodies and attachments — encrypted on your device
- Your private key and your passphrase — never transmitted
- Your password — the OPAQUE protocol never sends it
- Reactions, timers, unsend and destroy instructions — encrypted too
What Tor adds
- Your IP address at connection time — the connection reaches us from inside the Tor network
- Your approximate location, which follows from the IP
- Which network you are on — home, office, hotel
How to use it
- Open Tor Browser and type the onion address above. The whole route stays inside the Tor network, from the browser to our server: the connection passes no exit node, and no public name server is ever asked where you are going.
- Sign in as usual — the OPAQUE handshake and DPoP‑bound session work over Tor unchanged.
- Expect the first load to be slower than on a direct connection.
- Real‑time delivery uses a WebSocket, which works over Tor.
- Keep Tor Browser's default security level unless you know why you are changing it. JavaScript is required — it is where the encryption happens.
- app.privateki.net also opens in Tor Browser, and your mail is just as encrypted there. The onion address is the one that keeps the entire route inside Tor.
What Tor does not change
Who you write to, and when, is still visible to our server — that is how delivery works, and we publish that list. Tor hides where you are; Private.Ki hides what you said. Together they cover most of what an ordinary email provider can see about you.
