SecureLink Talk

SecureLink Talk is an app for encrypted calls and messages within a closed group of people who work together. The administrator of the service creates your account and sends you a personal invitation. Nobody else can sign up in the app, and strangers cannot find you. FEATURES • Calls encrypted directly between the phones. At the start of a call you can compare a short security word with the other person. • Messages, group conversations and attachments (documents, photos) encrypted on the phone. The server only delivers them and cannot read them. • Messages disappear by themselves 7 days after they are read; you can make the time shorter. • Location and other hidden data are removed from photos before they are sent. • Lock the app with Face ID or your passcode. • Calls ring even when the app is closed. • Block a contact and report an inappropriate message to the administrator. ENCRYPTION Calls and messages are protected by a combination of proven and post-quantum cryptography, so that intercepted communication cannot be decrypted in the future either. Encryption cannot be switched off. PRIVACY No ads, no analytics, no tracking. The server keeps no call history and cannot read your messages. See the privacy policy for details. The app is open source (GPLv3); the source code is publicly available.
