Privacy and scan data

Updated September 8, 2026. AI Crawler Checker is a no-login public URL scanner. This page explains the scan request, browser sharing, site analytics, and operational data. We do not send scans to an AI model or publish a public report database.

What you submit

When you run a scan, your browser sends the URL to our scan endpoint. Our server requests that public page, robots.txt, up to three public Sitemap declarations plus /sitemap.xml, and optional /llms.txt and /llms-full.txt. Public redirects or sitemap declarations can lead to other domains. Those destination sites receive our request and may log it. No browser login cookies or credentials are forwarded to the target.

Reports, links, and clipboard

The application returns the report to your browser with a no-store response and has no saved-report database. New share links keep the target in the URL fragment after #; anyone you share the full link with can see it and rerun the scan. Your browser history may retain the link. Older query-string share links still work and their query is included in the initial request to our host. “Copy full report” and fix-copy buttons write to your clipboard only when you use them.

Google Analytics

This site loads Google Analytics 4 to understand page usage and scanner interactions. Google may use analytics cookies and process browser/device information, approximate location, page visits, referral information, and events such as scan start, completion, failure, and copying a report. Our scan events include the tool mode, result category, and issue count; they do not include the submitted target URL or fetched page content. We configure page location and referrer without query strings or fragments, and disable Google Signals and advertising personalization signals in the tag configuration.

Google’s processing is described in how Google uses information from sites that use its services. You can block analytics using browser controls or the Google Analytics opt-out add-on. The scanner does not require analytics to run. No advertising code is currently installed on this site.

Operational data

Hosting and network providers may process request URLs, IP addresses, timestamps, status codes, and errors to deliver and protect the service. The scan endpoint uses an in-memory IP-based request counter with a ten-minute rate-limit window; that is not a promise that all infrastructure logs expire after ten minutes. Provider log retention is governed by their service settings and policies. We do not claim that visiting or scanning is anonymous to our hosting and analytics providers.

Use public URLs

Submit only URLs intended for public access. Do not include credentials, access tokens, secret links, or personal information in the URL. The scanner blocks recognized private/local hosts, limits response sizes and redirects, and does not log in or bypass access controls. Learn more about the service.
