Ant Messenger is open-source, secure, and virus-free encrypted communication software. Every installer is officially signed.

These system messages are routine security warnings and do not indicate a problem with the software:

• Windows: click “Run anyway”
• macOS: allow “Anywhere,” or Control-click the app to open it
• Android: allow apps from “Unknown sources”

• Confirm that the device system version meets the minimum requirements
• Restart the phone or computer
• Close unnecessary background apps to free memory
• Reinstall the latest version
• Disable blocking by antivirus or security software

This is caused by the macOS security mechanism and does not mean the file is damaged:

• Open “System Settings → Privacy & Security”
• Find the blocked system software notice
• Click “Open Anyway”
• Alternatively, Control-click the app icon to open it

Ant Messenger supports anonymous use and does not require a phone number to be linked.

You can:

• Register with an account name and password
• Hide your phone number
• Leave out real personal information
• Use the service completely anonymously

The platform does not collect, upload, or disclose users’ private information.

• Check that the phone number is correct
• Check spam messages or the blocked-message folder
• Switch networks and request the code again
• Wait 60 seconds before trying again
• Make sure the number has not been restricted by the platform

Common causes and solutions:

• Incorrect password → recover your password
• Network problem → switch between Wi‑Fi and mobile data
• Outdated version → update to the latest version
• Account protection is active → contact official support
• Multi-device conflict → sign out on other devices and log in again

For account security, the desktop version (Windows/macOS) uses QR-code login by default.

QR-code login helps:

• Prevent password leaks
• Prevent account theft
• Synchronize encryption keys automatically
• Keep messages encrypted throughout the process

Click “Forgot Password” on the login page and follow these steps:

• Enter your account name or phone number
• Obtain a verification code
• Set a new password
• Complete the reset

Ant Messenger uses financial-grade end-to-end encryption (E2EE):

• Messages are encrypted locally before being sent
• The server cannot decrypt any content
• International-standard encryption algorithms are used
• The open-source code can be audited independently

It is one of the most secure communication encryption solutions currently available.

End-to-end encryption means that only the sender and recipient can decrypt the messages.

This means:

• The server cannot view them
• Third parties cannot eavesdrop on them
• Network operators cannot monitor them
• No one can break the encryption

Your messages belong entirely to you.

Ant Messenger does not store messages in plaintext and does not monitor users’ chat content.

All messages use:

• Local encryption
• Encrypted transmission
• Encrypted storage
• No backdoors, surveillance, or uploading

In the chat window, go to Settings in the upper-right corner → Privacy Protection:

• Self-destruct: messages are destroyed automatically after viewing
• Two-way deletion: messages are deleted for both parties at the same time
• Anti-screenshot: prevents the other party from taking screenshots or screen recordings
• Trace-free messages: no local record is created

Yes. Go to:

• Me → Settings → Privacy
• Turn off “Find me by phone number”
• Hide the phone-number display
• Enable friend verification

Ant Messenger supports multiple devices online at the same time:

• Log in simultaneously on a phone, computer, and tablet
• Synchronize encrypted chat history in real time
• Synchronize file messages across devices
• Synchronize account status globally

Ways to restore chat history:

• Enable encrypted cloud backup
• Log in to the same account for automatic synchronization
• Restore from a local backup
• Restore by synchronizing from the desktop client

All records are stored in encrypted form and are completely secure.

• Make sure both devices are logged in to the same account
• Keep the network connection working normally
• Update to the latest version
• Log out and log in again
• Disable background power-saving restrictions
