Users' information security is a primary task of secure instant messenger SafeUM, that's why we implemented a reliable method of generating security keys. When you first log in the app, you can generate encryption keys based on the Passphrase.

Only the copy of your Public key is stored on our servers, as it's needed  for authentication and verification of your interlocutor. Private key is never sent to SafeUM servers, it's located in the  RAM of your device and is erased when you reboot or turn off  your device. If your interlocutor changes his security keys, you'll  get auto notification and will be able to decide whether or not to continue talking.

Isn't it possible to talk to Windows' owners and ask them to develop WinPhone further? 
But... We did not call them. Windows Phone is their product. They decide - whether to make it better or to kill it.
As they chose "to kill" - we stopped upgrading/supporting/thinking about/... WinPhone app too. 
Life is beautiful but volatile.   

WinPhone interface design is totally different from other platforms. SafeUM secure messenger has been developed taking into account this operating system requirements and its Metro design.

Our convenient user menu is superimposed over the multi-touch technology which makes the application so quick it simply slides under your fingers.

SafeUM  bright original design looks special in WinPhone turning the Love Tiles in bright, contrasting labels. This operating system is considered to be the golden mean between iOS and Android. We used that when creating the menu logic and interface usability.

Android is the world's most popular mobile platform. We have finished developing the mobile version application.

We designed a clear and easy-to-use interface allowing you to multitask without switching screens.

The application is easy to configure – that will require very little time. Our messenger has been tested on many different devices to find the best color schemes and create a convenient user menu. We took user habits into account and made our application navigation as comfortable and functional as possible. You can customize the menu to your needs just by clicking on one single page.  

The team of developers and designers working on SafeUM secure messenger is ready to present interface options for one of the most popular platforms - iOS.

Given the characteristics of the platform, usability has been thought through to minute detail and application design has been adapted to better suit all iOS features and functionality. Easy-to-use menu of the mobile version allows to customize the application according to your personal needs for the security level and anonymity. You can use the application more comfortably with the auto-rotation feature.

At the moment we are at one of the most important stages of our product development – the choice and implementation of encryption algorithms. The main goal of SafeUM secure messenger is its users' personal data and correspondence safety.

The primary task of  SafeUM is to protect privacy, information and data integrity of our users.

We used symmetric and asymmetric cryptography and El Gamal Public key encryption as basic ones. We want to make security a core idea surrounded by other messenger features. We also would like to give you the opportunity to control the security levels on your own.

When we started developing our messenger we already had its clear architecture and infrastructure in our minds. Design was also greatly discussed.

We decided to design the application interface in a measured, stylish and original way taking into account recent trends in the evolution of shapes and colors.

We finally chose contrast design having selected from the range of calm colors which are not hard on the eyes. When constructing the messenger architecture special attention was paid to its usability. All our buttons are quite informative, elements are clear and functionality helps to solve problems in a quick and easy way.
