Information you provide

The site has no user accounts, comments, newsletter form, or on-site contact form. Browser tools calculate locally and do not intentionally transmit their entries to the publisher.

Server logs

The hosting provider may process standard technical logs such as IP address, requested page, date and time, browser information, referring page, and error information for security, operation, and aggregate analysis.

Google advertising

Third-party vendors, including Google, may use cookies, web beacons, IP addresses, or other identifiers to serve, measure, and personalize advertising. Google’s use of advertising cookies enables Google and its partners to serve ads based on visits to this and other sites. Visitors may manage personalized advertising through Google Ads Settings and other controls made available by advertising providers.

Consent messages

Where required, a consent management platform may request choices concerning cookies, local storage, advertising personalization, and data processing. Google requires a certified CMP integrated with the IAB Transparency and Consent Framework for personalized advertising traffic in the EEA, UK, and Switzerland.

External links

Linked websites have their own privacy practices. The publisher does not control them.

Children

The site is general-audience educational content and does not knowingly request personal information from children.
