The mobile Tresor is a secure tool for saving sensitive information into your phone.
You can store your PINs, logins, passwords, secret contacts and text notes in Tresor. The sensitive information is then encrypted using strong AES symmetric cipher.
This version of Tresor is for all phones. There is also an extended version for phones with Bluetooth support. Its name is Tresor Blue and it is available on Nokia Softwaremarket too.
Tresor Blue can backup and restore the encrypted data by Bluetooth connection. Therefore, you do not lose your data even if you lose your phone, buy a new phone, or perform a firmware flash.
