Privacy policy

Last updated 9 October 2026.

The numbers you type

The calculators run in your browser. What you type into them is not sent to us, stored or logged, and it is gone when you close the page.

What we collect when you visit

Our web host keeps standard server logs: IP address, browser, the page requested and the time. They are used to keep the site secure and to find errors, and are deleted on the host's normal schedule.

Cookies

The site does not set any cookies at the moment. If we add analytics or advertising, this section will list the services and how to opt out.

You can block or delete cookies in your browser settings. Every calculator works the same without them.

Links to other sites

Some pages link to Shopify, Amazon, Etsy, fee schedules or our own apps. Those sites have their own privacy policies, and we do not control what they collect.

Children

This site is not meant for children under 13, and we do not knowingly collect their data.

Changes

If this policy changes, the date at the top changes with it.
