How it works

Polycred makes email privacy easier than ever before

Sign up to websites by generating email aliases. Send and receive emails using your personal email inbox. Emails sent to your alias simply appear in your email inbox, and your email replies are seamlessly relayed back to the sender. Your personal email address will never be shown to any sender or recipient, they will only see your alias.

Generate on sign up

Click the Polycred icon on email fields on a website's sign-up page to generate an email alias. All emails from this website will be sent to your alias which will appear in your personal inbox. Polycred will never reveal your personal email address to a website. Polycred is also compatible with password managers.

Log in to websites

Polycred remembers which generated email aliases belong to which websites, and will conveniently auto-fill log in forms for you.

Stay protected

If you are receiving spam or suspect a website has leaked your generated email alias you can disable or delete it with a single click. By using a unique alias on each website Polycred protects you against hackers and social engineering attacks.
