Privacy Policy

Last updated: September 2026

Short version

CalcKit calculators run entirely in your browser. We don't create accounts, and we don't receive or store the numbers you type into calculators.

What we store

• Local storage on your device: your theme preference (dark/light mode) and recent calculation history. This never leaves your device and you can delete it via your browser settings.
• Standard web logs: our hosting provider may log basic technical data (IP address, pages visited) for security and debugging.

Cookies & advertising

We may display ads (e.g. Google AdSense). Ad providers may use cookies to show relevant ads and measure performance. You can opt out of personalised advertising in your Google ad settings or via your browser's cookie controls.

Third parties

The currency converter fetches exchange rates from public rate APIs. Your conversion amounts are sent only as part of that rate request pattern (amounts are computed locally); no personal data is shared.

Children

CalcKit is a general-audience utility site not directed at children under 13.
