## What is graygate?

graygate is an end-to-end encrypted messenger built for privacy. Messages are encrypted on your device before they are sent, and the server can only relay ciphertext. It gives people a way to talk safely even where free expression is suppressed.

WHAT THE SERVER DOES NOT KNOW
• Your private key is created on your device and never leaves the iOS Keychain.
• Room keys are derived from the room password on each device. The server holds only a hash to check whether the password is correct.
• Encrypted messages wait on the server for at most 14 days so the recipient can pick them up. Once delivered, they are deleted immediately.
• Push notifications carry no content, no sender and no room name. Only the fact that something new arrived.

LEFT OUT ON PURPOSE
• No read receipts. Delivery is the last thing reported.
• No online or typing indicators.
• No cloud backup. Conversations live on your device only.
• No ads, no analytics, no phone number, no social login.

PROTECTION ON THE DEVICE
• App lock with Face ID, or an app PIN on devices without biometrics.
• Content is hidden in the app switcher, and a screenshot taken inside a room is announced to that room.
• Auto-delete per room: 1, 7 or 30 days.
• Key fingerprint check: compare 12 words and a group of digits to catch a server that tries to swap keys in the middle.

ROOMS
• One-to-one chats, group rooms, and channels where an admin posts and members reply with comments.
• Photos and videos are encrypted the same way as text. Videos are saved to your album rather than played inside the app.
• Removing a member always rotates the room key, so they cannot read anything that follows.

GOOD TO KNOW
• graygate is invite-only. You need an invite code from an existing user to create an account.
• If you switch devices, your past conversations do not follow you. That is by design.
• A 12-word recovery phrase resets your password and app PIN. It does not bring back past conversations.
• Who joined which room, and when a device connected, is stored on the server. Per-message forward secrecy is not provided.
• You must be at least 16 years old to use graygate.
