Privacy Policy

When you run a check, the address you enter is sent to our servers on Cloudflare, which request that address and return the result to your browser.

• The URLs and results are not saved to a database or linked to you.
• Browser-only tools — URL parser and encoder, query string parser, slug generator, UTM builder, URL cleaner, SEO URL checker, SERP and meta tag previews, the redirect rule, robots.txt, hreflang and schema generators, the QR code generator, and keyword analysis of pasted text — run entirely on your device and send nothing to us.
• For a WHOIS lookup, the domain name you enter is sent to IANA, to find the responsible registry, and to that domain registry's public RDAP service.
• For a DNS propagation check, the domain name is sent to twelve public DNS resolvers (Cloudflare, Google, Cisco OpenDNS, NextDNS, Control D, AdGuard, DNS.SB, dnsforge.de, LibreDNS, IIJ, AliDNS, DNSPod).
• The What Is My IP tool shows you your IP address and the approximate location Cloudflare derives from it; your browser may also ask Cloudflare’s public trace service (1.1.1.1 or www.cloudflare.com) for your address. Nothing is stored.
• Private and internal network addresses are rejected and never requested.
• For a DNS lookup, the domain name you enter is sent to Cloudflare’s public DNS resolver (1.1.1.1) to retrieve its records.
• For a Core Web Vitals check, the URL you enter is sent to Google’s PageSpeed Insights service, which loads the page and returns its performance data. Google’s privacy policy applies to that request.

If you create a shared report, the check results — including the URLs, status codes and response headers — are stored in Cloudflare KV under a random link and deleted automatically after 7 days. Anyone with the link can open the report during that time, so don’t share reports for URLs that contain passwords or access tokens.

When you request a page preview, the URL is passed to the preview source configured for the site: the page’s own Open Graph image, Cloudflare Browser Rendering, Microlink, ScreenshotOne or ScreenshotAPI. Generated previews may be reused for up to 24 hours.

When you use the contact form we store your name, email address, subject, message, the page language, the time of submission and your IP address in a Cloudflare D1 database. We use this only to reply to you and to prevent abuse of the form. Submissions are deleted automatically within 7 days; you can ask us to delete yours sooner at hello@urlscheck.com.

To protect the service, your IP address is used to apply per-minute request limits and is shared with Cloudflare Turnstile, which checks that requests come from a person rather than a bot. This is not used to build a profile of you.

We use Google Analytics to measure how the site is used, for example which pages and tools are visited. Google Analytics sets cookies such as _ga and collects usage data including your IP address and information about your device and browser. See Google’s privacy policy for details.

• Your light or dark theme choice is saved in your browser’s local storage and never leaves your device.
• You can block or delete cookies at any time in your browser settings.

Depending on where you live, you may have the right to access, correct or delete your personal data, to restrict or object to its processing, and to data portability. To exercise these rights, write to hello@urlscheck.com. You also have the right to lodge a complaint with a data protection authority.

We update this policy when the service changes. The date at the top shows the latest revision.
