Focus Lock Privacy Policy

Last updated: June 25, 2025

Focus Lock is a Chrome extension that helps you block distracting websites for a fixed period of time. Your privacy matters. This policy explains what information the extension handles and how it is stored.

Summary

Focus Lock stores all data locally on your device. The extension does not collect, transmit, sell, or share your personal information with any server or third party.

Information stored locally

When you use Focus Lock, the following data is saved in your browser using chrome.storage.local:

• Domain names you choose to block (for example, netflix.com)
• Block start and expiry timestamps
• An optional reason or note you enter when creating a block
• Internal identifiers used to manage blocking rules

This information stays on your computer and is used only to enforce blocks and show remaining time in the extension popup and blocked page.

What we do not collect

• No browsing history beyond the domains you explicitly block
• No account information — Focus Lock does not require sign-in
• No analytics, telemetry, or crash reporting
• No data sent to external servers

Permissions

Focus Lock requests Chrome permissions solely to provide blocking functionality:

• declarativeNetRequest — redirects navigation to blocked domains before pages load
• storage — saves your active blocks and expiry times on your device
• alarms — removes blocks automatically when their timer expires
• tabs — supports redirect behavior when a blocked site is opened
• Host access (<all_urls>) — required so blocking rules can apply to any website you choose to lock

Data retention and deletion

Block entries are removed automatically when their timer expires. You can also remove all extension data at any time by uninstalling Focus Lock or clearing the extension’s storage from Chrome’s extension settings.

Children’s privacy

Focus Lock is not directed at children under 13, and we do not knowingly collect information from anyone.

If this policy changes, the updated version will be published at this page with a revised “Last updated” date.
