Privacy
Your course scores are calculated in your browser. No school login or student name is needed.
Visits and tool actions
The site does not send calculator entries or page visits to an analytics service.
Scores and temporary storage
Calculator entries live in the open page. Choosing a connected tool puts only the needed values in session storage in this tab. The receiving tool reads and removes that handoff. Closing the tab clears it. There is no automatic permanent save.
A CSV download is created in your browser and saved wherever you choose. Copying a result puts that text on your clipboard. Hosting services may record request paths, IP addresses and browser information when serving pages.
Fonts and other websites
The fonts are served with this site, so opening a calculator does not request fonts from Google. Links to school policies open their own websites, whose privacy practices apply.
Contact information
The site does not accept contact messages or collect contact details.
