Information we collect
Calculators run locally in your browser; we do not require accounts for standard tools. We may receive aggregated analytics and advertising data as described below.
Cookies & similar technologies
We and our partners use cookies and similar technologies to measure traffic, remember preferences (such as language), and serve ads. You can control cookies through your browser settings.
Google AdSense
We use Google AdSense to display advertisements. Google and its partners may use cookies to serve ads based on your prior visits to this or other websites. You may opt out of personalized advertising by visiting Google Ads Settings or aboutads.info.
Analytics
We may use analytics services (including Google Search Console and similar tools) to understand how visitors find and use our pages. These services typically collect device, browser, and page-view data in aggregated form.
Third-party links
Our site links to related calculators and external resources. Third-party sites have their own privacy policies.
Children
Class-Run is not directed at children under 13. We do not knowingly collect personal information from children.
Data retention & security
We apply reasonable technical measures for a static website. No method of transmission over the Internet is 100% secure.

Depending on your region (including GDPR and CCPA), you may have rights to access, correct, or delete personal data held by processors we use. Contact us via the site operator channels you use for Class-Run support.
