Are chats end-to-end encrypted?

No. Chats are encrypted in transit (TLS) and at rest. They are not end-to-end encrypted, because human reviewers and automated systems (including OpenAI moderation) read messages, photos, video frames, and voice to keep the product 18+ and to stop abuse. If you want a channel we cannot see, rizzed is the wrong app. This is disclosed in Terms and Privacy on purpose.
