Privacy Policy

Last updated: July 2026

This policy explains what information FinCalc Lab ("we", "this site") collects when you visit, and how it is used.

The short version

  • Everything you type into our calculators stays in your browser. We never receive it.
  • We do not require accounts and do not collect names, emails or financial details.
  • Like most websites, we use advertising and basic analytics, which rely on cookies you can control.

Calculator inputs

All calculators on this site run entirely in your browser using JavaScript. The values you enter — incomes, debts, savings, prices — are processed on your device and are never transmitted to, stored on, or visible to our servers.

Analytics

We may use privacy-respecting analytics to understand aggregate traffic: which pages are visited, from which country, on what kind of device. This data is aggregated and cannot be used by us to identify you personally.

Advertising and cookies

This site is supported by advertising, including Google AdSense.

  • Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this or other websites.
  • Google's use of advertising cookies enables it and its partners to serve ads based on your visits to this site and/or other sites on the Internet.
  • You may opt out of personalized advertising by visiting Google Ads Settings. You can also opt out of some third-party cookies via www.aboutads.info.

Depending on your region (for example the EEA or UK), you may be shown a consent banner allowing you to accept or reject non-essential cookies before they are set.

We do not sell, rent or trade any personal information. We have no personal information to sell.

Articles may link to external sites we consider reputable. We are not responsible for their content or privacy practices.
