It is generally good security practice to have a PIN code lock on your phone.
Secure Your Device
In future releases of the Salvanote app, every time your smart phone enters ‘lock mode’ (ie the screen ‘turns black’), or it goes to screen saver, or the phone is turned off or restarts, access to Salvanote will end and commence again by entry of a PIN code chosen at start up (or via a fingerprint verification for devices that support this). However, until this feature is fully rolled out, access to the app will be by username and password. This obtains a login “token” which Salvanote will remember, even if the smart-phone is turned off and on again. To close the app in order to prevent unauthorised use you must log out. So if you do not log out and you have no security for your smartphone then anyone who gains access to your phone will be able to read your messages in Salvanote.
Therefore in order to secure the content of messages on your phone, it is important that you implement one or both of the following practices:
- Have a PIN code lock on your device to prevent unauthorised use.
- Logout of the app when finished using it (tap “Sign Out” from the menu).

For Android, this Google article explains the process of setting a PIN code (which they call a “screen lock”) on your Android device.
