Privacy Policy

Last updated: August 2026

Your calculations stay on your device. Every calculator on this site runs entirely in your browser. The numbers you type — your salary, your loan balance, your home price — are never transmitted to, seen by, or stored on our servers. We could not look them up if we wanted to.

We don't ask who you are. There are no accounts, no sign-ups, no newsletter box, and no contact forms. We don't collect your name or email address, and we don't sell or share data about you with anyone.

Analytics. We use Google Analytics 4 to understand how the site is used — which calculators people open, which guides they read, and whether they found us through a search engine. To do that, Google sets cookies in your browser and collects your IP address, device and browser type, the pages you visit, and an approximate location derived from that IP address. We see this as anonymous, aggregated reporting; we cannot use it to identify you personally, and it never includes the numbers you enter into a calculator. Google's own handling of this data is covered by the Google Privacy Policy. If you'd rather not be counted at all, Google publishes a browser opt-out add-on.

Advertising. This site displays ads served by Google AdSense. Google and its partner vendors may use cookies to serve ads based on your prior visits to this or other websites. You can review or turn off personalized advertising at My Ad Center, and opt out of third-party vendor cookies at aboutads.info.

Your choices. You can block or delete cookies in your browser settings at any time. Doing so will not break any calculator on this site — every one of them works with cookies and scripts from Google blocked entirely.

Children. This site is meant for a general adult audience and is not directed at children under 13. We don't knowingly collect information from them.

No advice. All calculators are for education and estimation only and do not constitute financial, tax, investment, or legal advice. Consult a qualified professional for decisions about your specific situation.

Questions or changes. If this policy changes we'll update the date at the top of this page. You can reach us through our Etsy shop.
