Bunsin is a browser extension for Chrome that serves as an add-on for the privacy-centric smartphone app of the same name. With Bunsin, users can create their own "Bunshin" (currently limited to email addresses).

By utilizing Bunshin, users can protect their privacy and detect/block unauthorized third-party usage or information leaks.

One of the key features of Bunshin is the ability to generate multiple temporary email addresses that can be forwarded to your main email address. This not only allows for easy identification of the source of unwanted emails but also enables users to block any suspicious senders.

Have you ever hesitated to provide your email address during registration because you were unsure how it would be used? Or have you received emails from unknown sources, wondering how they obtained your email address? With Bunshin, these concerns can be resolved.

By generating unique Bunshin emails for different services or registrations, users can easily manage their online presence. And when a Bunshin email is no longer needed, it can be easily deleted.

Furthermore, Bunshin helps users detect leaks or unauthorized sharing of their email addresses. If you receive an email on your Bunshin address that was only registered with Service A, but it's from Service B, you'll know that Service A might have leaked or shared your information.

Finally, Bunshin also helps prevent tracking. By using different Bunshin email addresses for different registrations, users can minimize the risk of being tracked across various online platforms.
