# Lauki - full reference

> Lauki is a messaging app with a mind of its own. You chat with friends, family and groups like any messenger, and Lauki, an AI assistant who lives in the app, takes care of the rest when you talk to him.

Short version: https://staging.lauki.chat/llms.txt

## What Lauki is

Lauki is a messenger for iPhone, Android and the web. Direct chats, group chats, photos, videos, voice notes and calls work the way they do in any messenger. The difference is Lauki himself: an AI account that sits in the app as a contact. Write to him in your direct chat, or tag @lauki, reply to him or say his name in any other chat, and he answers, looks things up, brings back an earlier message, or gets a task done.

Sign in with your phone number. A computer signs in by showing a QR code your phone scans and approves.

## When Lauki reads a message

- Your direct chat with Lauki: he reads everything you send him.
- Groups: once someone adds him he sees every message there until a member removes him; a group he is not in, he never sees.
- Direct chats between people: he never sees them, and tagging @lauki there does nothing. He also opens a message when you ask him to bring something back.
- Groups: the chat shows a notice when Lauki is turned on, and members can turn him off from the group's settings.

## Privacy and security (verbatim from https://staging.lauki.chat/privacy)

"Your messages are encrypted in transit and at rest, and we hold the keys. Lauki is not end-to-end encrypted. Every message travels to us over an encrypted connection and is stored in our database as ciphertext. Our server holds the keys, opens a message when someone with the right to see it asks, and writes every open to a log nobody can edit. That means the operator of Lauki can read your messages."

"Lauki's AI providers keep nothing: zero data retention — what you send is not stored by them and not used to train their models."

"Lauki is his own entity. The notes and memory he keeps about you live in a private container of his own, outside the chat database. As of today our admins can access that container. Ask him and he will tell you what he holds, or forget it."

"Every open of a message or file on the server writes one line: who asked, which chat, why, when. The table refuses edits and deletes, so the record exists before the reader finishes reading, and nobody can tidy it up."

## Your data

- Download everything: Settings, then Download my data, gives you one file with your profile, chats and every message you can see.
- Delete everything: deleting your account wipes your keys, sessions, devices and identity. What Lauki remembers about you is deleted with the account.
- Memory: what Lauki holds about you is shown in the app, read only, under Settings. Changing or clearing it goes through him.
