What is an atSign?


An atSign is your digital identity. It ensures that your data is 100% owned and controlled by you.

What can I do with my atSign?

At the moment, you can pair your atSign with any app on the atPlatform (the underlying technology behind atSigns) to enable the app to access, but not store, your data. The number of things you can do with your atSign will increase as more and more of these atPlatform apps are built.

While we wait for the rest of the Internet to catch up, you can get ahead of the game by downloading the first batch of recently launched apps. These include atmospherePro, an end-to-end encrypted file sharing app, and atBuzz, an entirely new and private way to connect with others, and more.

Discover these atPlatform apps here.
