What we collect. And what we don't.

What we do NOT collect

• Accounts, logins, or profiles. You never create an account to use the site.
• Cookies. DataGym.io sets no first-party tracking cookies.
• Personally identifiable information. No names, emails, individual IPs, or browser fingerprints.
• Cross-site tracking. We do not sell or share data with ad networks.

What our analytics provider sees

We use Plausible Analytics, a privacy-friendly analytics tool hosted in the European Union. Plausible records aggregate visit data; pageviews, country (not city), device type, browser, and the site that referred you.

This data is anonymous. No individual visitor is identifiable. Plausible does not use cookies and does not build cross-site profiles.

What stays in your browser

Some features save data in your browser's localStorage. For example, your theme choice (light or dark) and progress on path checklists.

This information stays on your device. It does not leave the browser. Clearing the site's data in your browser removes everything.

External labs

Some labs (like the Analytics Engineering Quest) run on their own domains. The same principles on this page apply to every DataGym.io property; no cookies, no accounts, no personal data.

When you click a link to a third-party site, that site's privacy policy applies, not ours.
