## What Merlin tells a chat

When Merlin joins a chat, it posts a message saying it's an AI, that it saves every message, that voice notes are transcribed, and where the privacy notice is.

## What Merlin keeps

- Every message in the chats it's in, with reactions and edits
- The text of files people send. The files themselves stay on the chat app.
- Each chat's memory and files
- Your email, name, picture, plan and timezone

Messages are kept until someone deletes them. Your data isn't sold, used for ads, or used to train AI.

## Who can see what

- People in a chat can ask Merlin about anything said in that chat.
- In your direct messages, Merlin can search all of your chats. In a group, it only searches your other chats if you turned that on for yourself, and it asks you each time.
- Other people can only use your apps as far as you allow in each chat. See [Connected apps](https://atmerlin.com/docs/connected-apps).

## Opting out

Anyone in a chat can type `/forget me`, with or without an account. Merlin deletes their messages in that chat and stops saving new ones.

## Deleting your data

- Unlink a chat app on Home to delete everything kept from that account.
- Unlink a connected app to delete everything Merlin had from it.
- Delete a chat from your archive after Merlin has left it.
- Download your data or delete your account in Settings.

Linked apps and synced logins are stored encrypted.
