 <p>We only recommend instant messenger programs or apps that support <a href="https://en.wikipedia.org/wiki/End-to-end_encryption">end-to-end encryption (E2EE)</a>. When E2EE is used, all transmissions (messages, voice, video, etc.) are encrypted <strong>before</strong> they are sent from your device. E2EE protects both the authenticity and confidentiality of the transmission as they pass through any part of the network (servers, etc.).</p>
