Privacy Policy
Last updated: November 14, 2026
1. What we collect
We do not ask for your name, email address or any other personal information, and you do not need an account. The numbers, dates and times you enter are processed only in your browser and are not sent to us. If you email us, we use your email address and message only to reply.
2. Information stored on your device
The basic and scientific calculators keep your last five calculations in your browser's local storage. This stays on your device and is never sent to us. Your language choice is kept in a small cookie named "lang", which is sent to this site with your requests and used only to open the page in the language you picked; it does not identify you. You can delete both at any time by clearing your browser's site data.
3. Advertising and cookies
We use Google AdSense to show ads. Google and its partners may use cookies or similar technologies to show ads based on your visits to this and other websites. You can turn off personalized ads at My Ad Center, and learn more at How Google uses information from sites that use its services. You can also opt out of some third-party vendors' cookies at aboutads.info. Visitors in the European Economic Area, the United Kingdom and Switzerland are asked for consent before personalized ads are shown.
4. Hosting and server logs
The site is hosted on Cloudflare. As with most websites, our host automatically processes technical information such as IP addresses and browser type to deliver pages and protect the site from attacks. Fonts are loaded from jsDelivr, which also receives your IP address when it delivers them.
5. Children
The site is for general audiences and does not knowingly collect personal information from children.
6. Your privacy rights (US, UK and EU)
- We don't sell your information. We do not sell or share your personal information for money. However, under some US state laws, the advertising cookies described in section 3 may count as a "sale" or "sharing" of personal information. You can opt out of this at any time by turning off personalized ads using the links in section 3.
- California residents. Under the California Consumer Privacy Act, as amended by the California Privacy Rights Act (CCPA/CPRA), you have the right to know what personal information is collected about you, to ask us to delete it, and to opt out of its sale or sharing. To make a request, email us at the address in section 8. We will not treat you differently for using these rights. Because we do not keep information that identifies you, we may have little or nothing to provide or delete; information held by Google can also be managed directly with Google. Residents of other US states with similar laws can make the same requests.
- Children under 13. In line with the US Children's Online Privacy Protection Act (COPPA), this site is not directed to children under 13, and we do not knowingly collect their personal information. If you believe a child has given us personal information, email us and we will delete it.
- UK and EU visitors. Under the GDPR and the UK GDPR, you have the right to access, correct and delete your personal data and to object to its processing. You can contact us at the address in section 8, and you also have the right to complain to your local data protection authority (in the UK, the Information Commissioner's Office).
