Privacy and security

Who can read my chats and hear my calls?

Only you and the people in the chat or call can read and hear what you send and say. Not even we can.

What’s end-to-end encrypted

  • Chats: text, photos, videos, voice messages, files and moments, in groups too. A group’s photo and description as well.
  • Calls and video calls: also in group rooms. Our server only forwards packets it can’t open. Nothing is recorded.
  • Notifications: the server only sends “New message”. Your iPhone fills in the text. In groups the notification only shows who is writing; you read the text in the app.

The server sees who writes to whom and when, but not what. It keeps messages encrypted until they’re delivered, files until the message expires, each for at most 30 days. Scheduled messages wait until their time.

What isn’t end-to-end encrypted

Communities: posts are encrypted in transit and on the server, but not end-to-end.

Compare the security code

With the security code you check that nobody is in between.

  1. Open the chat and tap the name at the top.
  2. Under Encryption, tap Security Code.
  3. Compare the 12 groups of numbers, ideally when you see each other.
  4. If they match, turn on Mark as Verified.

In a call, you’ll find the code under ••• › Compare Security Code.

Note: If the code changes, the chat shows it. This happens when someone has a new iPhone.

When someone reports

If someone reports a chat and includes messages, we see exactly those, at most 5. See Report someone.
