oChat is a messenger you can walk into. Sign in with Apple or Google in one tap — no phone number, no SMS code, no password to make up — and you are writing. The same account works on iPhone and on Mac. Your one-to-one chats and groups are end-to-end encrypted with Apple's own CryptoKit. Keys are set up on that first sign-in, so there is nothing to switch on. AND YOU CAN CHECK IT In a one-to-one chat, compare a fingerprint face to face — eight pictures, a 60-digit number, or the QR code you show each other — and the chat is marked verified. If that key changes later, a warning appears above the message field. Chats with our support team are not end-to-end encrypted, and the app says so on that screen. INSIDE • Chats and groups, with invite links you can revoke one by one. New members can get recent history from the person who added them. • Replies, edits, reactions, pinned messages, an archive and notes to yourself. • Photos, video, files, voice messages and video notes, encrypted on your device before they are uploaded. • A chat list that opens with no connection; an unsent message waits in the outbox and goes on its own. • Your chat history lives on your device. Our server holds a message only until your devices receive it, 30 days at most, and there are no cloud backups. To move to a new iPhone or Mac, enter a 6-digit code on your old one and your history comes straight across. • Notifications with no text in them: the push preview is encrypted, and our server cannot read it. • Privacy settings that work both ways, a Devices screen that closes any other session, plus reports, blocks and moderation labels. • 47 languages, a dark theme, links that open inside the app. PLANS Messaging, groups, encryption and opening any media sent to you are free. Premium is a monthly subscription. It adds sending media — photos, video, files, voice messages and video notes — and what else it includes is shown on the subscription screen in the app. A subscription renews automatically unless auto-renew is turned off at least 24 hours before the end of the current period. Manage or cancel it in your App Store account settings.
