Privacy policy

What these pages do

Both calculators are static pages. The arithmetic runs in your browser. Grades, percents, and other numbers you type stay on that page in your browser. This site does not send those numbers to a server, and it does not ask you to create an account.

What is not used today

Today these pages do not use analytics, cookies, advertising, or third-party services. They do not load an ad script, a measurement script, or a font or script from another site. The only files they load are this site’s own HTML, stylesheet, and calculator script.

Because nothing is collected, there is no profile, no stored history of your calculations, and no personal information for this site to sell or share.

If advertising is enabled later

Advertising is not enabled. This section applies only if Google advertising, including Google AdSense, is turned on later. It does not describe anything these pages do today.

If that happens, Google and its advertising partners may set or read cookies and use similar storage to show ads, limit how often you see an ad, and measure whether an ad was viewed. Google describes those cookies and the data they can collect in its own advertising and privacy policies. Those practices would apply only while such a service is actually enabled on these pages. Turning advertising on would also require this policy to be updated so it no longer says advertising is off.

Children

The calculators do not ask for a name, an email address, or any other contact detail. They are not a service that collects personal information from children.

Changes

If this site later adds analytics, cookies, advertising, or another third-party service, this page will be updated to say so. Until that change is written here, the “not used today” section is the one that matches the pages.
