Privacy Policy

Last updated: 23 September 2026

Short version

The BotLens Chrome extension collects no data. Everything happens locally in your browser. This marketing website uses a self-hosted, privacy-friendly analytics tool (Umami) to count anonymous page views. No cookies, no personal data.

The BotLens extension

What it 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 the extension does not do

• No analytics, telemetry, or crash reporting.
• No external servers. The extension 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.

That is the whole list. BotLens requests no host permissions. The robots.txt file and the raw HTML are fetched from inside the page you are analyzing, from that page's own site, so the extension needs no access to any other site.

This website (botlens.iamjarl.com)

The marketing site you are reading now uses Umami, a privacy-friendly, open-source analytics tool self-hosted on umami-iamjarl.vercel.app. Umami is loaded via a single <script defer> tag.

What Umami collects

• Page URL and title
• Referrer (the site you came from)
• Browser, operating system, and device type
• Approximate country (derived from IP, then IP is discarded)
• Anonymous, daily-rotating session hash

What Umami does not do

• No cookies
• No cross-site tracking
• No fingerprinting
• No personal data (name, email, precise location, IP) is stored
• No data shared with third parties

The analytics data is used solely to understand how many people visit the site and which pages are useful. Under GDPR, Umami's default configuration is generally considered exempt from cookie-consent requirements because it stores no identifiers on your device.

Opt out

If you prefer not to be counted, any of the following blocks Umami cleanly: enabling your browser's Do Not Track / Global Privacy Control setting (respected by Umami), using an ad-blocker like uBlock Origin, or blocking umami-iamjarl.vercel.app at DNS level.
