SEO Evidence Lab

This policy explains what SEO Evidence Lab, a Chrome extension for auditing technical SEO, does with your information. It is short, because the extension is built so that there is very little to explain.

SEO Evidence Lab is developed and published by Mad Max Labs. In this policy, we and us mean Mad Max Labs, and the extension means the SEO Evidence Lab Chrome extension.

The extension runs entirely in your browser. It has no account, no sign-in, and no Mad Max Labs server behind it. The pages it scans and the evidence it collects stay on your device, and this policy names the only network requests it ever makes.

Last updated 16 July 2026

The short version

If you read nothing else:

  • The extension examines a page only when you press Scan page on it. It holds no standing access to your browsing and does nothing in the background.
  • Scan results are stored locally in your browser's extension storage, on your device. We never receive them; we operate no server that could.
  • Its only network requests go to the website you are scanning: one repeat request for the page's own HTML and one request for that site's robots.txt file.
  • There is no advertising, no analytics, and no tracking, and we do not sell or share your data. We never hold it in the first place.

What the extension reads, and when

Chrome treats the content of the pages you visit as sensitive user data, and it is right to. The extension is therefore built around Chrome's activeTab permission, which grants access to a single tab, only after you act. Until you press Scan page, the extension cannot read the page in front of you.

When you do press Scan page, three collections happen, all scoped to that one page:

  • It reads the rendered document in that tab: the title, meta tags, headings, links, images, and structured data of the page your browser has built after scripts ran.
  • It asks that page to fetch its own URL one more time, to capture the raw HTML the server sends before any script runs. This is an ordinary same-origin request from the same tab, carrying the same cookies your browser would send for any load of that page, and it goes only to the site itself.
  • It fetches that site's /robots.txt file to evaluate crawler policy. This request is deliberately sent without cookies, so the extension sees the file the way a crawler would.

Both requests travel directly from your browser to the site you are scanning. Nothing about the scan, the URL, or the result is sent to Mad Max Labs or to anyone else.

What it stores, and for how long

Each completed scan is saved into Chrome's local extension storage so the History view can compare a page against its earlier runs. History is bounded: the extension keeps at most 25 scans within a fixed storage budget of about 4 MB, and older runs are dropped as new ones arrive.

This storage lives on your device only. It does not sync through your Google account, we cannot read it, and it is deleted when you clear history from the panel or uninstall the extension.

What leaves your device

In one place, the complete list:

  • The repeat page request and the robots.txt request described above, both sent to the website you are scanning, at the moment you scan it.
  • If you click an Official source link in the AI access view, your browser opens that documentation page in a new tab, exactly as any link would.
  • Reports you export as Markdown or JSON are files you save yourself. The extension writes them to your device and sends them nowhere.

That is the whole list. The extension makes no other network requests, and no request of any kind reaches Mad Max Labs.

Permissions, and why each one

The extension requests four Chrome permissions:

  • activeTab: to read the page in the tab where you pressed Scan page. One tab, only after you act, only until you navigate away.
  • scripting: to run the collector inside that page. This is the mechanism that gathers the rendered evidence and performs the two requests above.
  • sidePanel: to show its interface in Chrome's side panel next to the page, rather than in a pop-up that closes when you click away.
  • storage: to keep scan history on your device, as described above.

It requests no host permissions and no access to your browsing history, cookies, downloads, or bookmarks. What it reaches is always one page, at your instruction.

What the extension does not do

Some things are easier to state plainly:

  • No analytics, telemetry, or usage tracking of any kind. We do not know who installed the extension, what you scan, or how often.
  • No advertising.
  • No account and no sign-in.
  • No reading of tabs you have not scanned, and no scanning in the background.
  • No selling, renting, or trading of data. We hold none to trade.

If you install the extension from the Chrome Web Store, Google shows us aggregated statistics such as install counts and ratings. That is a store platform service, it does not identify you, and the extension's own code reports nothing.

Chrome Web Store Limited Use

The use of information received from Google APIs will adhere to the Chrome Web Store User Data Policy, including the Limited Use requirements.
