Clear, fair, and transparent rules for using Locksy. No hidden catches.
By installing, accessing, or using the Locksy browser extension ("the Extension") or visiting the Locksy website ("the Website") at locksy.dev, you agree to be bound by these Terms of Service ("Terms").
If you do not agree to these Terms, please do not use the Extension or Website. We reserve the right to update these Terms at any time, and continued use after changes constitutes acceptance of the revised Terms.
Locksy is a browser extension that provides password-based tab protection for all major browsers, including Chrome, Edge, Firefox, Brave, Opera, and Vivaldi. It is available in a Free Core version with an optional lifetime Pro upgrade.
The Extension allows users to lock browser tabs with a master password, set auto-lock timers, schedule locking periods, lock entire domains, use biometric authentication (via WebAuthn/FIDO2), right-click context menus for quick locking, stealth mode to disguise locked tabs, and toggle between light and dark themes.
All data processing occurs entirely on the user's device. No personal data, passwords, or browsing activity is transmitted to any external server.
There are no age or geographic restrictions for using Locksy. The Extension is available to anyone with a supported web browser. No account creation or personal information is required.
Locksy is proprietary software. You are granted a non-exclusive, personal, non-transferable, revocable license to use the Extension for your personal, non-commercial security purposes subject to these Terms.
You MAY NOT: lease, rent, redistribute, sell, or modify the Extension; attempt to reverse-engineer, decompile, or bypass the extension's security features; or misrepresent the origin of the software.
While the extension's source code is proprietary, Locksy is built with strict privacy constraints. No personal data, passwords, or browsing activity is ever transmitted to any external server.
Users can verify that no network requests are initiated by the extension by auditing network activity logs locally using their browser's built-in developer tools.
THE EXTENSION IS PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTIES OF ANY KIND, EITHER EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT.
While we strive to provide robust tab protection using industry-standard cryptographic methods (PBKDF2 with 600,000 iterations), we do not guarantee that the Extension will be error-free, uninterrupted, or completely secure against all possible attack vectors.
You acknowledge that no software can provide absolute security, and you use the Extension at your own risk.
To the maximum extent permitted by applicable law, the developer(s) of Locksy shall not be liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of profits or data, arising out of or related to your use of the Extension or Website.
This includes, but is not limited to, any data loss resulting from forgotten passwords (which cannot be recovered due to the zero-knowledge architecture), browser compatibility issues, or interactions with other extensions or browser updates.
Locksy will never charge you. No premium tiers, no subscriptions, no paywalls.
All your data belongs to you and stays on your device. We never access or transmit it.
Remove the Extension at any time. All locally stored data is automatically deleted.
Source code is public. Audit, inspect, and verify every claim we make.

These Terms shall be governed by and construed in accordance with applicable laws. Any disputes arising from or relating to these Terms or the use of Locksy shall be resolved through good-faith negotiation first, and if necessary, through appropriate legal channels.
If any provision of these Terms is found to be unenforceable, the remaining provisions will continue in full force and effect.
