About Just1 Password

→ Concept Neither the master password nor any other password is stored. Your passwords are mathematically generated on demand, from information only you know (master password, stored in your head 😉). → Why? If your computer or another password management tool's database is hacked, you can lose/give away all your passwords ! 🔐 PRIVACY POLICY Neither Just1 Password nor its authors collect any information about the use of Just1 Password. Just1 Password stores your settings (site name and email addresses) locally on your device. This information is never transferred by Just1 Password. Your browser may collect data about your usage. Please refer to your provider's policy for details. In addition, if you have enabled data synchronisation in your browser, your browser may transfer and store this data on a synchronisation server.
