Privacy Policy

Last updated: April 2026

Locktab is a browser extension that locks any tab behind a blurred overlay for instant privacy. We take privacy seriously — which is why we made this easy: we collect absolutely nothing.

What data we collect

None. Locktab does not collect, transmit, or store any personal data on any external server. Ever.

What stays on your device

The extension stores the following data locally in your browser using chrome.storage.local:

Your list of auto-locked domains, your chosen unlock mode (drag or password), your overlay strength preference, your auto-relock and lock-on-blur settings, a SHA-256 hash of your password (if you set one), an access log of unlock attempts (last 50 entries), and a tamper detection flag.

Your install date is also stored in chrome.storage.sync so it can survive an uninstall/reinstall (if you are signed into Chrome). This is used solely to detect whether the extension was reinstalled — no other data is synced.

None of this data is ever transmitted anywhere. It never leaves your device and is never accessible to us or any third party.

Permissions we request

tabs — needed to read the current tab's URL so we can show the correct domain in the popup and apply auto-lock rules.

storage — needed to save your auto-lock list and settings locally on your device.

activeTab — needed to inject the lock overlay into the current tab when you click the extension.

scripting — needed to inject the lock overlay into tabs that were open before the extension was installed.

Third parties

There are no third-party analytics, trackers, or advertising SDKs in Locktab. The extension makes no outbound network requests.

Changes

If this policy ever changes, we'll update the date above and post it here.
