Send encrypted texts, voice messages, photos, and make calls — all protected by military-grade encryption.
Every message is encrypted before it leaves your device. Even we can't read your conversations.
Record and send voice messages instantly. They vanish when you want them to.
Audio and video calls with end-to-end encryption. No logs, no records.
Set messages to disappear after 1 hour, 24 hours, or 7 days. Leave no trace.
Share photos that only your contact can see — fully encrypted, never stored in plain sight.
The app locks automatically when you leave. Your secret stays secret, always.
Silens uses military-grade end-to-end encryption. Messages are encrypted on your device before sending. Even our servers only see scrambled data — impossible to decode without your private key, which never leaves your phone.
Join thousands of people who chose to keep their conversations private.
