Your data is encrypted before leaving your computer to the Internet. And the encryption key based on your login-passward pair doesnt leave your browser.
So the only way to get access to your data is to know your login-passoword. Even if our servers are hacked or someone sniffs your traffic - hackers will get only the encrypted data - to decrypt it they need to know your login-password.
That is why we have no "password reset" option - we cant decrypt your data if you forget your password.
If you got a friend from security industry – ask him to check how our web service work – he will confirm it.
