Data sources & takedown

Funnelens is built on unique, structured data. This page explains where that data comes from and how to ask us to remove content.

1. Where the data comes from

• Ads: primarily the official Meta Ad Library API, which publishes public ad-transparency data.
• Funnels / landing pages: we follow the link behind an ad to capture public page content (screenshot, headline, offer) and measure page speed.

2. How we collect responsibly

• We prefer official APIs over scraping wherever one exists.
• We respect robots.txt, rate limits, and each site’s terms when capturing pages.
• We store only what is needed to provide the Service.

3. No affiliation with Meta

Funnelens is an independent product and is not affiliated with, sponsored by, or endorsed by Meta. References to Meta and the Meta Ad Library are for identification only.

4. Takedown requests

If you are an advertiser or site owner and would like content relating to you removed, email info@ddbros.cz with the relevant URL(s) or ad reference. We will review and respond promptly.

5. Our own analytics

For our own product analytics we use PostHog, configured privacy-first: EU-hosted, anonymous (we never identify visitors), no advertising cookies (browser localStorage only), Do Not Track respected. We capture page views, product events, and session replays with all typed input masked, so nothing you type is recorded. No personally identifiable information is collected. We also use Vercel Web Analytics for aggregate, cookieless visitor and page-view counts. See our Privacy Policy for details.
