✏️ Privacy Policy
Last updated: 2026-07-03
ip-check.leeguoo.com ("this site") is an IP purity / network-risk self-check tool. This policy explains what it collects, uses and protects when you visit. Using the site means you agree to these practices.
Information we process
- The IP you check: by default your own egress IP (ASN, organization and approximate location provided by the Cloudflare edge); when you pass
?ip=, the IP you entered. - Access logs & device info: browser type, referrer, time, approximate location — for security, rate-limiting and troubleshooting.
- Cookies & local storage: for analytics, advertising, and remembering your visitor identifier (below).
- API-key usage: when you sign in via account.leeguoo.com and use an API key, we record that key's daily request count for quota — not request contents.
How IP data is used
- Only to produce this check's result and to rate-limit — never to profile or persistently track you.
- For arbitrary
?ip=lookups, the IP is sent to Team Cymru (DNS-over-HTTPS) and public sources like ipapi.is / ip-api.com to obtain ASN and reputation data. - Results are cached per IP for up to ~1 hour to reduce repeat calls to upstream sources.
Third-party advertising (Google AdSense)
- This site uses Google AdSense. Third-party vendors including Google use cookies to serve ads based on your visits to this and other sites.
- Manage or opt out of personalized ads at Google Ads Settings, or opt out of some vendors at aboutads.info.
- See Google Privacy & Terms for how Google uses data on partner sites.
Analytics
This site uses first-party analytics and Google Analytics to understand usage. These collect anonymized data (page views, dwell time) via cookies and are not used to identify you personally.
Use of information
We use information only to operate and improve the site, secure and rate-limit it, provide API quota, and serve and measure ads. We do not sell your personal information.
Your choices
- Clear or disable cookies in your browser; some features may then not work.
- Opt out of personalized ads via the links above.
- To delete API keys or usage tied to your account, contact us at the email below.
