This Privacy Policy explains how Calculators Cafe ("we", "us", "our"), operating the website at calculators.cafe, handles information when you visit our website. Using our site means you agree to the practices described here. Please also read our Terms of Use.
1. The short version
- You do not need an account to use any calculator.
- We do not ask for, collect or store your name, email address or any personal details when you use a calculator.
- All calculations happen in your own web browser — your numbers are never sent to our server.
- Like most websites, we use cookies and analytics to understand how the site is used and to show advertising.
2. Information we collect automatically
When you visit Calculators Cafe, standard technical information may be collected automatically by our web server and by third-party analytics tools. This can include your IP address, browser type and version, device type, operating system, pages visited, time spent on pages and the website that referred you. This data is aggregated and used to keep the site secure, diagnose problems and understand which calculators people find useful.
3. Cookies
A cookie is a small text file stored on your device by your browser. We and our partners use cookies to remember your preferences, measure site traffic and deliver and measure advertisements. You can disable cookies in your browser settings, but some parts of the site may then work differently. Cookies set by us are not used to collect personal information about you.
4. Advertising and Google AdSense
We display advertisements served by third parties, including Google AdSense, to keep the site free. Google and its partners may use advertising cookies (for example the DoubleClick cookie) to serve ads based on your prior visits to this and other websites. Third-party vendors, including Google, use cookies to serve ads on our site.
- Personalised ads: Google may use your browsing history to show you ads that are more relevant to you.
- Opting out: You can opt out of personalised advertising by visiting Google Ads Settings, or learn more at aboutads.info.
Please note that opting out of personalised advertising does not remove ads — it simply means the ads you see will not be based on your interests.
5. Where calculations happen
Every calculator on this site runs in your browser using JavaScript. The figures you enter are processed locally on your device and are not transmitted to, or stored by, our servers.
6. Third-party links
Pages on our site may link to other websites (for example, our advertiser links or Google's opt-out pages). We are not responsible for the privacy practices or content of those third-party sites, and we encourage you to read their privacy policies.
7. Data retention and security
We keep aggregated analytics and server logs only for as long as is needed for the purposes described above. While no method of transmission over the internet is completely secure, we take reasonable measures to protect our website and the limited information it processes.
8. Children's privacy
Calculators Cafe is a general audience website and is not directed at children under the age of 13. We do not knowingly collect personal information from children. If you believe a child has provided us with personal information, please contact us and we will remove it.
9. Changes to this policy
We may update this Privacy Policy from time to time. Any changes will be posted on this page with an updated revision date at the top, so please check back occasionally.
