Tabseq is a passcode-based website blocker (a “focus guard”) for Google
Chrome. This policy explains what data the extension handles and how.
The short version: Tabseq does not collect, transmit, sell, or share
any personal data. It has no servers, no analytics, and makes no network requests.
Everything it stores stays on your own device.
What Tabseq stores (on your device only)
Tabseq saves your settings using Chrome’s local storage (chrome.storage.local)
on your computer:
A one-way hash (SHA-256) of your passcode — never your actual passcode.
An optional second “redirect” PIN hash and the destination URL you choose for it.
The list of websites you choose to lock, and your selected lock mode.
Your optional schedule, attempt limit, and lockout duration.
Short-lived unlock and lockout timers used to enforce your locks.
This information never leaves your device and is used solely to make the blocker work.
What Tabseq does not do
Does not collect personal or sensitive information.
Does not read, store, or transmit the content of the web pages you visit.
Does not track or record your browsing history.
Does not use analytics, advertising, or any third-party services.
Does not send any data to the developer or to anyone else.
Does not sell or share your data — there is no data to sell.
Permissions and why they are needed
tabs — to read the current tab’s address in the popup, redirect a
tab to the passcode screen when a locked site is opened, and clear a tab’s temporary
unlock when it closes.
storage — to save the settings listed above locally on your device.
webNavigation — to detect navigation to a website so it can be checked
against your lock list before the page loads.
alarms — to run a periodic local cleanup of expired unlock/lockout
timers.
Host access (all sites) — because you can lock any website you choose,
the extension must be able to recognize and intercept navigation to any URL on your
personal lock list. URLs are only compared locally and are never recorded or sent anywhere.
Data retention and deletion
Your settings remain on your device until you change them, clear the extension’s storage,
or uninstall Tabseq. Uninstalling the extension removes all of its stored data.
Children’s privacy
Tabseq does not knowingly collect data from anyone, including children.
