!Locker

Encrypt and lock your personal data such as personal life information, private user documents, financial information such as accounts, transactions, reports, credit card information, bank account details etc.
It encrypts the data using your encryption key and lock the access using your user account created on registration.
We never save your encryption key on our server, so the content will be encrypted from your device using the key provided and sent to the server as encrypted text over SSL.
Only the encrypted data is stored in our server, and the key for encryption is on your side, so the data is totally secured. And one thing you have to keep in mind is that "never forgot is the encryption key". This will be required whenever you install the app on a new device. You can change the encryption key at any point of time.
The encryption key will be saved only in your device, so if you install the software on a new device, you have to update the encryption key to access the details.
