Secure messaging and privacy
All text and media messages are protected with point-to-point encryption. Only you and your contact can read the information you send or receive.
Messages self-destruct by timer
Messages automatically self-destruct and can never be recovered. Set the timer for self-destruction and stay confident your message is deleted from both handsets - forever.
Encrypted file transfer
Send and receive sensitive information safely. Sicher heavily encrypts text messages, documents and media files and never stores them on servers.
Safe login with passcode
Create a passcode upon first launch and use your phone number to log into the service. Your passcode is encrypted and there's no tool to hack it. None of your personal data is stored on Sicher servers.
Free chat and media sharing on-the-go
Exchange messages and media for free. No upfront cost, no annoying ads, no subscription fees. Sicher is free and unlimited.
Collaborate and talk in groups
Collaborate on projects with team members and take part in group discussions. Create encrypted chats to discuss issues and share files.
No open data in Push notifications
Push notifications tell you about new messages but don't show what the messages are about. This protects your privacy and makes mobile messaging even more secure.
