Privacy Policy

All calculations run locally in your browser. The values you enter (prices, salaries, balances, hours) are not sent to our servers.

For convenience, the calculators may remember your last values and your theme preference by saving them only in your browser's local storage. That information never leaves your device, and you can erase it by clearing the site's data in your browser.

If you write to us through the contact form, your name, email and message are sent via FormSubmit, a third-party service that delivers them to our inbox. That service processes the submission under its own terms and privacy policy.

We use your email only to reply to you. We do not add it to any list, we do not send you promotions and we do not share it with third parties.

We may collect aggregate, anonymous usage metrics — such as which tools are used most and from what kind of device — to improve the site. These metrics do not include the values you type and do not identify you personally.

The site is funded by advertising. Ad providers, such as Google AdSense, may use cookies or device identifiers to serve ads and measure their performance, including personalized ads under their own policies.

You can limit personalized advertising from your Google account's ad settings or your browser, and block third-party cookies in your browser settings.

Some pages may link to external sites. We don't control the privacy practices of those sites; review their policies when you visit them.

If this policy changes, we will update this page. For privacy questions, write to us from the contact page.
