Every tab you were protecting — banking, email, work — is open to anyone who picks up your device. Putting that back takes about thirty seconds.
Chrome, Edge or Firefox — pick yours here. Or tell us what went wrong first.
Pick whatever applies. We'll tell you straight away whether it was something you could have fixed — and we read every one of these.
Goes straight to the developer. No mailing list, no follow-up spam.
The two things people usually move to instead are a separate browser profile or a tab manager. Neither is built to keep one tab shut while you keep working in the others.

“Usually the extension lets you right in on other tab lockers, but this one always asks for your pin, making it my favorite one.”

Locksy has no servers, no accounts and no analytics. It made zero network requests while it was installed, so nothing about your tabs ever left the machine you're reading this on.
Only a PBKDF2-SHA256 hash at 600,000 rounds — roughly twice the 2023 OWASP recommendation — with a random salt unique to your install. It can't be turned back into your password by us or anyone else.
A lock unloads the page rather than covering it, and the extension is what reopens it. Reinstalling protects you from here on, but it can't bring back a session that was locked at the moment you uninstalled.
The full detail is in How your data is handled — or read our privacy policy.
If you left because of a problem, we'd still like to fix it — whether you come back or not.
