Files saved on your computer or mobile phone should be encrypted to keep them safe.
To enable encryption for Windows computers: see How to Enable BitLocker (for WIndows 10). See Windows 7 instructions here.
To enable encryption on your iPhone/Android: see our blog post on Device Security: scroll down to the section on iPhone, and just below that on Android.
Also, your computer or device should be password protected. Enabling encryption will force you to add a password to unlock your device (if it is not already password protected). Password and encryption work together, as explained here.
