Encryptr is simple and easy to use. It stores your sensitive data - like passwords, credit card data, PINs, or access codes - in the cloud. However, because it was built on the zero-knowledge Crypton framework, Encryptr ensures that only the user - not the app's developers, cloud storage provider, or any third party - has the ability to access or read the confidential information.
Encryptr only ever encrypts or decrypts your data locally on your device. No plain text is ever sent to the server, not even your passphrase. This is what zero-knowledge means.
You don't even need to hand over any personal data to register. The app only requires a username and a passphrase. It doesn't require your email address or your name. Nothing.
Encryptr is free, and completely open source. This includes Crypton.
Being cross-platform, it allows users to securely access their confidential data from a single account - across Android, Windows, or Mac OS X - from the cloud no matter where they are.
