Privacy Policy

This policy explains what data Calc Garden collects and how it is used. The short version: we keep things minimal. There are no user accounts, and the numbers you enter into our calculators stay on your device.

Calculations run in your browser

Every calculator on Calc Garden runs entirely client-side. The values you type are processed in your browser to produce a result. We do not send those values to a server, and we do not store them. When you close or refresh the page, the inputs are gone.

Personal data we collect

We do not ask you to create an account, and we do not collect names, email addresses or other personal information through the calculators. If you choose to email us, we will only use your message and contact details to reply to you.

Advertising cookies

We use Google AdSense to display ads, which helps keep the calculators free. Google and its partners may use cookies and similar technologies to serve ads based on your prior visits to this and other websites. You can control personalised advertising in your Google Ads Settings, and you can learn how Google uses data when you use our site in the Google partner sites policy.

Analytics

If analytics are enabled, we may use privacy-conscious tools such as Google Analytics and Microsoft Clarity to understand which calculators are used and how pages perform. These tools collect aggregate, non-identifying usage data such as page views and device type, and they may set cookies to do so. They do not receive the values you enter into calculators.

Cookies, advertising & analytics

Calc Garden uses cookies and browser local storage for two purposes: advertising and analytics. For advertising we use Google AdSense, which may set cookies to serve and measure ads. For analytics we use Google Analytics, Microsoft Clarity and Vercel Web Analytics to understand which calculators are popular and how pages perform. These tools may set their own cookies and collect aggregate, non-identifying usage data such as page views, device type and approximate location.

We also record anonymous first-party usage events of our own, such as which calculator a page opened and that a calculation was run. These events contain no personal data and no raw IP address, are not tied to any account, and are never linked back to a specific person. They do not include the values you type into a calculator.

When you first visit, a cookie-consent banner lets you accept or decline personalised advertising. We use Google Consent Mode v2, so until you accept, ads are served in a non-personalised mode. Your choice is stored in your browser's local storage. You can withdraw consent at any time by clearing this site's cookies and local storage in your browser, which makes the banner appear again on your next visit. You can also control personalised advertising in your Google Ads Settings and read how Google uses data in its partner sites policy.

Affiliate links

Some pages may include links to third-party products or services marked as recommended tools. A few of these are affiliate links, which means that if you sign up or buy through one, we may earn a commission at no extra cost to you. This never changes the result a calculator produces, and we only suggest tools we consider relevant to the calculation on the page.

Your choices

You can block or delete cookies in your browser settings at any time. Doing so will not affect the calculators, since they do not rely on cookies to work. Clearing this site's cookies and local storage also withdraws your advertising consent, as described above.
