Privacy Policy
Last updated September 14, 2026
Overview
This policy explains what information ExtFoundry collects on extfoundry.com (this website), how it is used, and who it is shared with. It does not cover the individual Chrome extensions or apps we build — each one has its own privacy policy, linked from its Chrome Web Store or App Store listing and, where applicable, its own product page.
Information We Collect
On extfoundry.com, we collect:
- Standard analytics via Google Analytics — pages viewed, approximate location (derived from IP address), device and browser type, and referring site.
- Free tool input — if you use a free tool such as the AI Visibility Checker or Website Image Size Checker, we process the URL you submit to generate your result. Aggregate, non-personal results (the domain scanned and the public technical findings) may be stored to power the tool's own history and rate-limiting features.
- IP address — used transiently to apply rate limits on free tools and to deduplicate anonymous page-view counts. We do not build profiles from it or retain it long-term tied to an identity.
We do not require account creation, passwords, or payment information to use this website, and we do not run forms that collect personal details such as your name or email address.
Cookies
Google Analytics sets cookies to distinguish visitors and measure site usage. You can block or delete these through your browser settings; the site continues to function normally without them.
Third-Party Services
- Google Analytics — website usage analytics. See Google's privacy policy.
- Cloudflare — hosting, content delivery, and security for this website.
Individual apps (for example, an iOS app using Google AdMob for ads) may use additional third-party services — see that app's own Support & Privacy Policy page for details.
Data Retention
Analytics data is retained according to Google Analytics' standard retention settings. Free-tool scan results are kept only as long as needed to power the tool's own features and are not linked to your identity.
Children's Privacy
This website is not directed at children under 13, and we do not knowingly collect personal information from children.
Changes to This Policy
We may update this policy as the website or its tools change. The "Last updated" date above reflects the most recent revision.
