Before purchasing or subscribing to Claude, check whether the current browser, system region, and network exit show an obvious inconsistency. Browser fingerprint signals are calculated locally. The public-IP check requires a request to this site's Cloudflare Worker.

What the browser can see
A webpage can read the browser’s inherited time zone, languages, locale, user agent, and some font signals. It cannot read all system information available to Claude Code or know Anthropic’s actual decision rules.
Why the score is only a reference
This page combines several weak signals into a 0–100 score. Font and user-agent detection can be affected by privacy browsers, compatibility modes, and system updates, so the score locates inconsistencies; it does not predict an account outcome.
What to know before scanning
How to interpret the result
The score on this page is a heuristic assessment based on signals visible to the browser. It is not an official risk decision from Anthropic or Claude. One matching signal does not mean an account will necessarily be restricted. Consistent account details, device settings, and network exits usually matter more than reaching a particular score.
If the network check identifies a proxy, data-center address, or high-risk exit, continue with the Proxy-Service Reviews and VPN Selection Guide and decide whether to change networks based on routing, risk history, and your use case.
