How is it possible that no one (including SMSee staff) can read my messages/contacts?
Data is encrypted on your devices (mobile phones, tablets and web browser) with your secret key before it is sent to our servers. SMSee servers then send that encrypted data back to your other devices and they are the ones that can only decrypt it because they poses same secret key. Since secret key is stored only on your devices (mobile phones, tablets and web browsers) there is no way we can decrypt your data and see the content.
