Kisapp Smart Ephemeral and Encrypted Instant Messaging App.

We’ve developed a ground-breaking, patent-pending technology to provide people around the world with a maximum level of security and a unique instant messaging experience. As we strongly believe messages do not have to live forever and you shouldn’t have to worry about your information falling into the wrong hands, our revolutionary algorithm sets up an optimal timer before self-destruction for every message you receive, allowing you to focus on what’s really important: keeping in touch with the people you care about.

Preserving Your Privacy

We’ve designed Kisapp to preserve your privacy. Unlike most other messaging services, our users fully own their conversations and we will never monetize their personal data in any way whatsoever. Your messages are your business, not ours. Your communications are protected by our self-destruction algorithm along with multilayers of end-to-end encryption. Once a message is gone, deletion is instantly synchronized across all your devices, and our technology ensures it cannot be forensically recovered from any device.
We do not scan your communications and we have no way of decrypting your data. The only key able to decrypt your messages, your private key, is lodged in a place of your device that nobody can gain access to. We have also set up a strict policy regarding screenshots. Should any screenshot be made by one of your contacts, you would be notified immediately with a copy of the screenshot, and the account of the user would be blocked indefinitely after several attempts.

We place our users' privacy at the forefront of our mission. Period.

Kisapp Breakthroughs

Even though a few companies have approached encryption and self-destruction,
we take great pride in having created the very first truly smart ephemeral mechanism exclusively for Kisapp.

  • Smart ephemeral

    Depending on the content of your message, the in-app algorithm sets up an optimal self-destruction timer, and you can switch between 3 speeds of deletion whenever you want.


    Ultra secured communications using multiple layers of encryption. Not a single piece of information is transiting in clear. Your private key never leaves your phone.


    Kisapp is designed to ensure the utmost confidentiality. Access to the app is protected by a password authentification or by using Apple's Touch ID. Nobody but you can enter Kisapp.


    We strongly believe that great security should not compromise speed. That’s why we’ve made Kisapp one of the fastest and most reliable IM apps ever.


    Your account will be instantly synchronized throughout your different devices. A message gone on the iPhone, is a message gone forever, everywhere.


    Switch to our night mode automatically when it’s dark or anytime you want, and enjoy an elegant redesigned interface that is extremely comfortable in low light conditions.

Even though a few apps have approached encryption and self-destruction, the proposed solutions are so far perfectible and come at the high cost of an impoverished user experience.

Simple, as your right to privacy.
