Secure messenger SafeUM for Android download

Secure, no-cost messaging with SafeUM

SafeUM is a free messaging service designed to keep conversations private while remaining easy to use. The app runs on multiple platforms and encrypts data with strong cryptography so messages cannot be read by third parties during transit.

Strong encryption and privacy measures

Messages are protected using 256-bit encryption applied before they leave your device, so only the intended recipient can decrypt and read them. Connections are secured end-to-end, and the platform provides options for anonymous communication, including a private mobile number you can assign to your account.

Virtual phone numbers and calling

SafeUM lets you obtain anonymous mobile numbers from a selection of countries. You can register a number inside the app and add credit using a debit or credit card; payments are processed through a trusted payment gateway. Outgoing calls use your in-app number, while incoming international calls to those numbers are accepted without charge.

Suitable for professional use

The service supports business use — teams can exchange messages securely across different operating systems without needing specialized IT expertise. Companies can also acquire mobile numbers through the same in-app process, making it straightforward to provide secure communications for employees.
