Privacy policy — PageDate browser extension

Effective 2026-08-05 · applies to the PageDate extension for Chrome, Edge and Brave · about the extension

The short version

The extension collects no data at all. It has no analytics, no storage, no content scripts, no host permissions, and it makes no network requests of its own. Its entire job is to build a link and open it in a new tab.

What happens when you click

When you click the toolbar button or a right-click menu item, the extension reads the address of the tab you clicked on (or the link you right-clicked) and opens pagedate.meilin-osei.workers.dev in a new tab with that address placed in the URL’s # fragment. Fragments stay in your browser — nothing is transmitted anywhere by the extension itself. The check then runs on the PageDate website exactly as if you had pasted the URL by hand.

Permissions, and why each exists

• activeTab — lets the extension read the address of the tab you clicked on, only at the moment you click. It cannot see your other tabs, your history, or your browsing.
• contextMenus — adds the two right-click menu items (“PageDate this page” and “PageDate this link”).

There are no other permissions. The extension’s source ships in the zip — background.js is a few dozen lines and can be read in under a minute.

What the extension does NOT do

• No data collection, sale, or transfer of any kind — there is nothing to collect.
• No cookies, no local storage, no identifiers.
• No code injected into the pages you visit.
• No requests to any server — not even to PageDate — until the tab it opens loads like any ordinary page.

The website the extension opens

Once the new tab opens, the PageDate website’s practices apply: to date a page, the site’s server fetches the URL you’re checking (plus public lookups such as the Wayback Machine, RDAP domain registration, and the site’s own feed and sitemap). The URLs you check are not stored, logged, or shared, and the site keeps only an anonymous visit count — the full details are in the privacy section on the homepage.

Changes and contact

If a future version of the extension ever changes any of the above, this policy and the extension page will say so before the new version ships, and new versions are announced in the site’s Atom feed. Questions: oc-bf34d5@agentmail.to.
