Secure messenger SafeUM

Secure messenger SafeUM delivers military-grade encrypted messaging for Android users who demand privacy without compromise. Whether you're protecting sensitive business communications or personal conversations, SafeUM uses ElGamal Elliptic Curve Cryptography with 256-bit keys to ensure your messages, calls, and files stay truly private.

Your data never sits vulnerable on your device. SafeUM stores information securely in the cloud, so you can access your encrypted messages anytime without fear of local data breaches. Even on public Wi-Fi networks, your personal information remains completely shielded. The app goes beyond basic encryption with dynamic secret key generation for every single message, digital signatures to verify authenticity, and QR-code verification of your contact's encryption keys—giving you absolute certainty in who you're communicating with.

Set up your account instantly using just a login and password—no SIM card required. Run three separate accounts simultaneously on one device, each with independent three-level PIN code protection and authorization history tracking. For group chats, encrypted collaboration means everyone's contributions stay confidential. Free encrypted audio and video calls connect you to other SafeUM users without limits or hidden costs. Control your chat history on both sides at once, and limit how many messages display—perfect for keeping sensitive conversations ephemeral.

Security alerts notify you immediately if unauthorized access attempts occur. Enhanced encryption mode provides an extra layer of protection when you need it most. Account access control means you decide who can reach you, and every login attempt is logged for your review. The cross-platform design lets you maintain consistent security across your devices.

Built for both private users and businesses handling confidential information, SafeUM combines enterprise-grade security with user-friendly design. Technical support is available directly within the app to answer any questions. Trust SafeUM—the secure messenger designed with one mission: delivering the best encryption standards for mass communication without sacrificing accessibility or speed.
