Answers to common questions about the Lumotraq extension: privacy and data, supported browsers, how the measurement works and how to reach out.
Questions about the Lumotraq extension. For how we measure, see the methodology; for plans, see pricing; for the full data policy, see the privacy policy.
The extension detects the ads and trackers a page loads, on your device, to estimate their footprint. We don't build a profile of your browsing and we don't collect personal data. Before you create an account, only anonymous, aggregate measurements are processed — for example, how many ads were seen and their estimated CO₂ — and the specific sites you visit are not sent. Full per-domain history is only stored once you've signed up and given consent.
By default Lumotraq only measures — it shows the carbon footprint of the ads you see without changing the page. Blocking is a separate mode you can switch on if you want it.
Chrome, Microsoft Edge, Firefox, Brave and other Chromium-based browsers. It's live in the Chrome Web Store, Microsoft Edge Add-ons and Firefox Add-ons; Brave installs it from the Chrome Web Store.
Yes. Our backend runs in an EU region and our product analytics use an EU-based service, routed through our own lumotraq.com domain.
They measure different things. The extension measures your own live browsing session with ads actually loaded, while the Ad-Carbon Index estimates a site from a single cold homepage visit. Both are correct for what they measure, so they won't match.
Lumotraq shows a compact popup by default. In Settings you can switch it to open the full side panel when you click the toolbar icon.
No. That's a standard notice Chrome shows some users for newer extensions, and only to people who have turned on Enhanced Safe Browsing. It clears over time as our verified-publisher status builds. Your data and the extension's behaviour are unaffected.
Yes. Use the "Add this domain" request on our Ad-Carbon Index page. Requests are logged and reviewed for the next update, and the most-requested domains are prioritised.
You can pause measurement any time from the extension without uninstalling, or remove it entirely from your browser's Extensions menu like any other extension.
