Calculators Labs is a free tool for running calculations. We do not require accounts, email addresses, or any personal information to use this site. This page explains what data passes through the site and how it is handled.
1. Calculator Inputs
When you type numbers into a calculator, that data is processed entirely in your browser using JavaScript. Calculator inputs and results are not sent to our servers, not stored in a database, and not associated with you in any way. Once you close or navigate away from the page, that data is gone.
2. Analytics
We use Google Analytics to understand how visitors use the site — which calculators are used, how long pages are visited, and where traffic comes from. This data is aggregated and anonymous. We cannot identify individual visitors from analytics data.
Google Analytics sets cookies in your browser to distinguish sessions. You can opt out by installing the Google Analytics Opt-out Browser Add-on, or by using your browser's privacy or incognito mode.
3. Advertising
To keep this site free, we show ads through Google AdSense. Google may use cookies to serve ads based on your prior visits to this and other websites. This is called interest-based advertising.
You can control or opt out of personalised advertising through Google's ad settings or through the Network Advertising Initiative opt-out page.
If you prefer not to receive personalised ads, these opt-out tools will tell Google and its partners to stop using your browsing history for ad targeting. You will still see ads, but they will be less tailored to your interests.
4. Cookies
This site uses cookies set by Google Analytics and Google AdSense. We do not set any first-party cookies ourselves beyond what the browser requires to serve the page.
You can manage or delete cookies through your browser settings. Blocking all cookies may affect analytics reporting but will not break the calculators — all calculation logic runs without cookies.
5. Server Logs
Like most web servers, our hosting infrastructure logs basic technical information when a page is requested: the page URL, timestamp, browser type, and approximate geographic region derived from IP address. These logs are used for diagnosing errors and monitoring site health. We do not use server logs to track individual visitors.
6. Third-Party Links
Some calculator pages link to external resources such as reference materials or related tools. Once you leave Calculators Labs, this privacy policy no longer applies. We recommend reviewing the privacy policy of any external site you visit.
7. Children
Calculators Labs is intended for general use including students and educators. We do not knowingly collect personal information from children under 13. Because the site requires no account and collects no personal data directly, there is nothing specific for children to submit.
8. Changes to This Policy
If we add new features that change how data is handled, we will update this page and revise the "Last Updated" date at the top. Continued use of the site after a policy update constitutes acceptance of the revised terms.
