Have I Been Pwned
haveibeenpwned.com
Tells you which data breaches your email address has turned up in
justdeleteme.xyz
A directory of the direct links for deleting your account on hundreds of sites.
Every entry is a service, a colour-coded difficulty rating from easy to impossible, and a link straight to the page that closes the account — plus notes when the only route is emailing support or ringing them. It exists because deletion is deliberately buried, and finding the page is most of the work. Start here when you are cleaning up after a breach notification.
Questions
Works the moment the page loads. No account, no email, no trial. It is a community-maintained list, so a link can point at a page a company has since moved or removed.
Yes. JustDeleteMe sends your input to its own servers to process it. That is fine for public material; for anything containing personal data, use one of the on-device tools instead.
