Information we collect directly
None through accounts or forms. There is no login, no registration, no comment system, and no contact form. The calculators on this site (statistics, slope, linear equations) run entirely in your browser; the numbers you type are never sent to our servers or stored.
If you email us, we receive your address and message and keep them only as long as needed to respond.
Information collected automatically
Server logs
Our hosting provider (Vercel) records standard request logs, which may include IP address, browser type, referring page, and the pages requested, for security and reliability. These logs are retained for a limited period and are not used to identify individuals.
Google Analytics
When enabled, we use Google Analytics 4 to understand which pages are read and how visitors arrive. Analytics uses cookies and similar identifiers to distinguish sessions and collects data such as pages viewed, approximate location derived from IP, device and browser type. IP addresses are not logged or stored by Google Analytics 4. You can opt out with the Google Analytics opt-out browser add-on.
Advertising: Google AdSense
This site displays ads served by Google AdSense. Google and its partners are third-party vendors that use cookies, web beacons, and similar technologies to serve ads based on your prior visits to this website and other websites. In particular:
- Google uses the DoubleClick / DART cookie and related identifiers to serve ads and measure their performance.
- Ads may be personalized based on your interests as inferred from browsing activity across sites, unless you have disabled ad personalization.
- Third-party vendors, including Google, may collect your IP address and information about your device and browser in the course of serving ads.
You can control this:
- Opt out of personalized advertising by Google at Google Ads Settings.
- Opt out of many third-party vendors' personalized ads at aboutads.info/choices (US) or youronlinechoices.eu (EU).
- Block or delete cookies in your browser settings. The site remains fully usable without cookies.

Visitors in the EEA, UK, and Switzerland
Where required by law, a consent message is shown before personalized ads are served, using Google's certified consent management messaging delivered with the ad script. You can change your choice from the privacy link shown to visitors in those regions. Non-personalized ads may still use cookies for frequency capping, fraud prevention, and aggregate reporting.
Children
This site is written for students, parents, and teachers. Some pages are useful to students under 13. We do not knowingly collect personal information from anyone, and we do not run accounts or forms that would allow a child to submit it. The site is directed at a general audience of students, parents, and teachers rather than at children under 13. If you believe a child has sent us personal information by email, contact us and we will delete it.
