Medium severity
Share 𝕏 Share in Share 🔒 PDF

What it is

Cloudflare automatically collects your IP address, browser type, and browsing behavior not just when you use Cloudflare's own products, but also when you visit any website that uses Cloudflare's infrastructure — even if you've never heard of Cloudflare.

Consumer impact (what this means for users)

Your IP address and browsing metadata are collected by Cloudflare every time you visit a website that uses Cloudflare's network, creating a data footprint with a company you may never have knowingly interacted with.

Why it matters (compliance & risk perspective)

Because Cloudflare handles a significant portion of global internet traffic, this passive collection affects an enormous number of people who have no direct relationship with Cloudflare and may be unaware their data is being collected.

View original clause language
When you visit our websites or use our Services, we and our third-party service providers may collect certain information automatically. This includes information such as your Internet Protocol (IP) address, browser type, Internet Service Provider (ISP), referring/exit pages, operating system, date/time stamp, and clickstream data. We also collect this type of information when users visit websites of our customers who use our Services, as part of providing those Services.

Institutional analysis (Compliance & legal intelligence)

REGULATORY FRAMEWORK: Automatic collection of IP addresses and browsing data constitutes processing of personal data under GDPR Art. 4(1) and requires a lawful basis under Art. 6. The ePrivacy Directive (2002/58/EC) and its national implementations govern use of tracking technologies and require consent in most EU jurisdictions. CCPA §1798.140(o) defines 'personal information' to include IP addresses and browsing history, triggering disclosure and opt-out obligations. FTC Act Section 5 applies to any deceptive omissions about the scope of data collection.
