Help across the network

Open the app, choose Register, pick a username and password, enter your invite code, and accept the Terms of Use. KocaX Messenger is invite-based to keep the network safe — ask an existing member for a code, or request one by emailing us.

Tap the gold + button, choose New chat, and enter your contact's exact username. Usernames are exact and never listed publicly to protect everyone's privacy, so ask your contact for theirs. Tap Start chat and send your first encrypted message. To create a group, use New group instead.

Yes. Your messages and files are locked on your device before they're sent, and only you and the person you're chatting with hold the key to unlock them. Because we don't hold those keys, we don't have the readable content of your messages to hand over. We never sell your data, show ads, or track you. (For the technically curious: authenticated P-256 ECDH, HKDF-SHA-256, AES-256-GCM, and an independent Double Ratchet implementation.)

Open a chat, tap the timer next to the message box, and choose how long messages should last — from view-once and 5 seconds up to 24 hours. New messages in that chat delete themselves automatically after the chosen time.

Open the chat, tap the ⚙ menu, and choose Block or Report. Blocking removes the contact and stops all messages from them. Reports go to our safety team, which acts on violations within 24 hours. KocaX Messenger has a zero-tolerance policy for abuse.

Your account is protected by your password and a personal master key. Keep your master key safe: because your data is end-to-end encrypted, we cannot reset it for you. Log in with your username, password and master key on any device to restore access.

Email info@kocaexpress.com from the address linked to your request, or use the in-app profile options, and we will remove your account and associated data.
