About Locksy
A free, open-source browser extension built to give you complete control over your tab privacy. No compromises, no tracking, no cost.
Why Locksy Exists
Locksy was born out of a simple yet urgent need: protecting sensitive browser tabs on shared computers. Whether you're a student in a library, an employee in an open office, or a parent sharing a family computer — there's always a risk of someone seeing tabs you'd rather keep private.
Existing solutions were either too complex, charged money for basic features, or collected user data. Locksy set out to be different: 100% free, completely offline, and privacy-first from day one.
Today, Locksy protects thousands of users across Chrome, Edge, Firefox, Brave, Opera, Vivaldi, and more — all while keeping your data entirely on your device.
What We Stand For

Full transparency. The entire codebase is public on GitHub so anyone can audit, verify, and contribute.
Free Forever
No premium tiers, no subscriptions, no ads in the extension. Locksy is and always will be completely free.
Zero Compromise
