Privacy policy

The short version: your calculator inputs stay on your device.

Last updated November 15, 2026.

Calculator inputs

All calculations run in your browser. The numbers you enter are not sent to or stored on our servers. If you use the copy link button, your inputs are written into that link so the result can be reopened. Anyone you send the link to will see those numbers.

Data stored on your device

The site saves a few preferences in your browser's local storage: your theme choice, your chosen currency and your answer to the analytics notice. They never leave your device, and you can clear them in your browser settings.

Analytics

We use Google Analytics 4 and Microsoft Clarity to understand which pages are used and where people get stuck. Both run without analytics cookies until you choose Allow in the notice. If you allow them, they set cookies and collect usage data such as pages viewed, approximate location, device type, and clicks and scrolling. Clarity may record how a page is used; calculator inputs are masked. We do not use advertising cookies, and we do not sell personal data.

You can change your mind at any time by clearing this site's data in your browser, which brings the notice back. See the privacy information published by Google and Microsoft for how they process data.

Hosting

The site is served by Cloudflare, which processes technical data such as IP addresses to deliver pages and protect against abuse.

Your rights

Depending on where you live, you may have the right to access, correct or delete personal data, or to object to its use. We hold no account data about visitors. For any request, email hello@capitalcalculators.com.

Children

The site is not directed at children under 13 and does not knowingly collect their data.

Changes

If this policy changes, the new version will be posted on this page with a new date.
