Privacy Policy

What we collect, what we don't, and how third-party services like Google Analytics and Google AdSense are used on this site.

Last updated: August 19, 2026

CommonDataSets ("we," "us," or "this site") is an independent, non-commercial-in-purpose project that publishes publicly available university admissions data. This Privacy Policy explains what information is collected when you visit the site, how it's used, and what choices you have. We do not require an account to use this site, and we do not knowingly collect names, email addresses, or other information that directly identifies you.

Information We Collect

We collect two categories of information:

  • Automatically collected usage data — through Google Analytics, we receive standard technical information such as your approximate location (derived from IP address), browser and device type, pages viewed, referring site, and time spent on the site. This data is aggregated and is not used by us to identify you individually.
  • Locally stored preferences — features like Favorites and recently viewed schools are saved using your browser's local storage. This information stays on your device; it is never transmitted to us or stored on our servers. Clearing your browser data removes it.

We do not operate user accounts, do not collect payment information, and do not knowingly collect sensitive personal information of any kind.

Cookies & Similar Technologies

This site uses cookies and similar technologies placed by us and by the third-party services described below. Cookies are small text files stored on your device that allow a site or service to recognize your browser across visits. You can disable cookies through your browser settings, though some site functionality may not work as intended if you do.

Third-Party Services

We rely on the following third-party services, each of which may set its own cookies and process data under its own privacy policy:

  • Google Analytics — measures site traffic and usage patterns so we can understand how the site is used and improve it.
  • Google AdSense — displays advertising on this site and may use cookies to personalize the ads you see based on your visits here and to other sites. Google's own privacy practices for this data are described at policies.google.com/technologies/partner-sites.
  • Google Fonts — page text is rendered using fonts served from Google's font infrastructure, which involves your browser requesting font files directly from Google.
  • Supabase — our backend data service, used to serve the university admissions data shown on this site. It does not collect personal information on our behalf beyond standard technical request logs (such as IP address and timestamp) common to any web infrastructure provider.

Advertising & Your Choices

You can opt out of personalized advertising from Google by visiting Google Ad Settings, and you can opt out of personalized advertising from other participating companies through the Digital Advertising Alliance's opt-out page. Most browsers also let you block or delete cookies directly in their settings.

How We Use Information

Aggregated analytics data is used only to understand how the site is used and to guide improvements — for example, which schools or comparison features are most useful to visitors. We do not sell personal information, and we do not share data with third parties beyond the service providers named above, except where required by law.

Data Retention

Analytics data is retained according to Google Analytics' standard retention settings. Locally stored favorites and history remain in your browser indefinitely until you clear your browser data or remove them yourself; we have no access to this information and no ability to delete it on your behalf.

Children's Privacy

This site is not directed at children under 13, and we do not knowingly collect personal information from children under 13. If you believe a child has provided us with personal information, please contact us so we can address it.

International Visitors

This site is operated from the United States. If you access the site from outside the United States, your information may be processed in the United States and other countries where our service providers operate, which may have different data protection laws than your home jurisdiction.

Your Rights

Depending on where you live, you may have rights under applicable law (such as the GDPR or CCPA) to request access to, correction of, or deletion of personal information we hold about you, or to opt out of certain data processing. Because we do not collect directly identifying information ourselves, most such requests are best directed to the third-party service in question (for example, Google) using the tools linked above. You're welcome to contact us as well, and we'll assist where we're able to.

Changes to This Policy

We may update this Privacy Policy from time to time as the site or the services it relies on change. The "Last updated" date at the top of this page reflects the most recent revision. Continued use of the site after a change means you accept the updated policy.
