OARS by Knov.ai · Browser extension

Privacy Policy

Last updated: June 3, 2026

OARS by Knov.ai ("the extension") is a toolbar extension that scans the website you are currently viewing for agent-readiness signals and displays the results. This policy explains exactly what the extension does and does not do with data.

What the extension accesses

When you click the OARS toolbar icon, the extension:

  • Reads the current tab's URL and page content signals (Schema.org JSON-LD, heading structure, canonical link) directly in your browser.
  • Reads the response headers of the page you navigated to (e.g. HSTS, CSP, Content-Signal, Link), in observational mode only.
  • Fetches public files from the website you are viewing — /robots.txt, /llms.txt, and standard /.well-known/* discovery files — to check which agent-readiness signals are present.

All of the above happens locally in your browser and is shown only to you.

What is sent off your device

The extension makes one request to a third party: it sends the hostname of the site you are currently viewing (for example, example.com) to the Knov.ai directory API at knov.ai/api/directory/:domain to look up that site's public OARS directory listing. No other information is included with this request — it is not associated with your identity, account, or browsing history.

No other data is transmitted anywhere.

What the extension does NOT do

  • It does not collect, store, or transmit personally identifiable information.
  • It does not track your browsing history or build a profile of your activity.
  • It does not collect page content, form data, credentials, or cookies.
  • It does not use analytics, advertising, or third-party trackers.
  • It does not sell or share any data with third parties.

Data storage

Scan results are cached temporarily using chrome.storage.session so that reopening the popup on the same site is fast. This cache exists only for the current browser session and is cleared automatically; nothing is written to long-term storage or sent to any server.

Permissions

The extension requests activeTab, scripting, storage, webRequest, and host access to http://*/* and https://*/*. These are used solely to scan the site you are actively viewing when you click the icon. Broad host access is required only because you may run a check on any website; the extension contacts only the site you are currently on (plus the single Knov.ai directory lookup described above).

Changes

If this policy changes, the "Last updated" date above will be revised.
