Support

Sentrix is the secure, end-to-end encrypted messaging and calling app of the Counter Terrorism Department (CTD). Accounts are issued by CTD to authorised personnel only; there is no public sign-up.

Contact

• Officers: contact your CTD IT administrator first. They manage accounts, sign-in, groups and devices.
• Technical support: the IntelXOne support team at sentrix-support@clerint.org. Include your service number, your device model and the app version (Settings → About). Never send a password, PIN or recovery code by email.

Getting the app

• iPhone: install Sentrix from the App Store. Requires iOS 17 or later.
• Android: install Sentrix from Google Play, or download it from this server's download page.

Signing in

• Tap Sign in with SSO and sign in with your CTD Identity account and second factor.
• If you have forgotten your password or lost your second factor, your CTD IT administrator can reset it. Support staff will never ask for your password.

Lost or replaced phone

• Report a lost or stolen phone to your CTD administrator immediately, so the device can be removed from your account.
• Moving to a new phone: use Settings → Backup & Transfer on the old phone to move your data securely.

Common questions

• Why can't I take screenshots? Screen capture protection is set by CTD policy to protect sensitive conversations.
• I'm not receiving notifications. Check that notifications are allowed for Sentrix in the phone's Settings, and that Focus or Do Not Disturb is off.
• Calls don't connect. Check your internet connection and that Sentrix has microphone (and, for video, camera) permission.

Reporting a security issue

If you believe your account or a device has been compromised, contact your CTD administrator at once. To report a vulnerability in the app or service, email sentrix-support@clerint.org.
