Privacy Policy
Last updated: July 2026
The short version
Everything you type into our calculators stays in your browser — it is never sent to our servers or stored anywhere. The site uses cookies only for advertising and basic analytics, described below.
Calculator inputs
All calculations run entirely in your browser using JavaScript. Salary figures, loan amounts, property prices and any other numbers you enter are not transmitted to us, logged, or shared with anyone.

Analytics
We may use privacy-respecting, aggregate analytics (page views, referrers, country) to understand which calculators are useful. This data is not used to identify individuals.
If you email us, we keep the correspondence only to respond to it. We don't add you to any list, and we never sell or share your address.
Data we do not collect
No accounts, no sign-ups, no forms that store data, no calculator inputs. We do not knowingly collect any information from children.
