Privacy Policy

⌨️ Data you enter into tools

Age, dates, and times you type into our calculators are processed locally in your web browser using JavaScript. This information is never transmitted to our servers, stored in a database, or shared with anyone.

🍪 Cookies

We use the following cookies and browser storage:

• Theme preference: stored in your browser's local storage on your device, not in a cookie.
• Google Analytics 4 cookies: _ga and _ga_<container-id>, set by Google Analytics to measure visits (see Analytics below).
• Advertising cookies: none today, because the site currently shows no ads. If advertising is added in future, the ad provider may set its own cookies.

You can control cookies through your browser settings, and you can opt out of Google Analytics at the Google Analytics opt-out page (tools.google.com/dlpage/gaoptout).

📢 Advertising

This site currently shows no advertising. If advertising is added in future, it may be served through Google AdSense. Google's use of advertising cookies would then enable it and its partners to serve ads based on your visit to this site and other sites on the internet. Learn more in Google's Privacy and Terms.

📊 Analytics

We use Google Analytics 4 (Measurement ID G-Q6NE2Q4XTM) to understand which tools are popular, so we know what to improve. Google Analytics sets first-party cookies and collects visit data such as pages viewed, browser and device information, and approximate location, and sends it to Google. You can opt out at tools.google.com/dlpage/gaoptout.

🧒 Children's privacy

Our tools are general-purpose and do not target children specifically. The dates and times you enter into the tools are processed only in your browser and are not collected by us. Google Analytics visit data is handled as described in the Analytics section above.

🔄 Changes to this policy

If this policy changes, we will update the date at the top of this page. Continued use of the site after changes means you accept the updated policy.
