Privacy Policy

Last updated: 25 May 2026

Short version

BotLens does not collect, store, or transmit any personal data. Everything happens locally in your browser.

What BotLens accesses

When you open the BotLens popup on a page, the extension:

• Reads the active tab's URL, meta tags, headings, image alt text, and DOM size.
• Fetches the site's /robots.txt file and the raw HTML of the current page in order to compare it with the rendered DOM.

All of this happens inside your browser. None of the data leaves your machine.

What BotLens does not do

• No analytics, telemetry, or crash reporting.
• No external servers — BotLens has no backend.
• No cookies, no user accounts, no advertising.
• No selling or sharing of data, because no data is collected.

Permissions explained

• activeTab / scripting — needed to read the page you are currently viewing when you click the BotLens icon.
• host permissions (all URLs) — needed to fetch robots.txt and the raw HTML of the active page for comparison. This permission is only exercised when you actively trigger analysis.
