Your conversations,
end-to-end encrypted.
Private messaging, groups, calls and calendar — backed by your mindlog identity. Nothing travels in the clear, everything stays yours.
No trust required
What the server sees, and what it does not
An encrypted service that stays vague about metadata is asking you to take its word for it. Here is the precise answer.
What it carries
Who writes to whom, and when. That metadata is needed to deliver a message — no messenger avoids it, so we say so plainly.
What it cannot read
Content, attachments, voice notes. It holds only opaque blobs: the keys live in your browser, never on it.
What never crosses it
The audio and video of your calls: it goes straight from one browser to the other. The server only relays signalling.
A message’s journey
Encrypted with you, opaque everywhere else
The message is encrypted before it leaves your browser and only becomes readable again at its destination. In between, the server carries something it cannot open — then erases it.
Conversation
Messaging that keeps nothing
Read receipts, reactions, disappearing timers and read-once messages — none of it readable on the server.
- 60-digit safety number to verify who you are talking to
- Per-conversation timer, down to 5 minutes
- Read-once messages, erased once revealed
- Attachments and voice notes encrypted client-side
Groups
Together, without giving anything up
Groups use sender keys: every message is signed, and the key rotates as soon as a member is removed. The server only knows who belongs.
- ECDSA P-256 signature per message, against forgery
- Key rotation when a member is removed
- Attachments encrypted in groups too
Calendar
Book a meeting without a middleman
Set availability day by day, with a general rule and exceptions. A visitor picks a free slot and leaves you a request.
- Fifteen-minute, half-hour or hourly slots
- Slots already taken are greyed out
- You accept or decline — nobody else
