This Privacy Policy explains how Calculators4.com ("we", "us") handles information when you use our website. By using the site, you agree to the practices described here.
Calculator inputs stay on your device
Our calculators run entirely in your browser. The numbers and details you enter are processed locally and are not transmitted to or stored on our servers. We do not ask you to create an account and do not collect names, email addresses, or financial information through the calculators themselves.
Information collected automatically
Like most websites, we and our service providers may automatically collect limited technical information such as your IP address, browser type, device type, pages visited, and referring site. This is used to operate the site, understand aggregate usage, and improve our tools.
Cookies and similar technologies
We and third parties use cookies and similar technologies to remember preferences, measure traffic, and serve advertising. You can control or delete cookies through your browser settings; disabling them may affect some functionality.
Advertising
We may use third-party advertising companies, including Google, to serve ads when you visit the site. These companies may use cookies and device identifiers to show ads based on your visits to this and other websites.
- Google's use of advertising cookies enables it and its partners to serve ads based on your visits. You can opt out of personalized advertising by visiting Google Ads Settings.
- You can opt out of personalized ads from many vendors at aboutads.info/choices or youronlinechoices.eu.
Analytics
We may use privacy-respecting analytics to understand aggregate, anonymized usage (for example, which calculators are most popular). This data does not identify you personally.
Your privacy rights (GDPR / CCPA)
Depending on where you live, you may have rights to access, correct, or delete personal information we hold about you, or to opt out of the "sale" or sharing of personal information. Because we do not collect personal information through our calculators, most requests relate to advertising cookies, which you can manage using the opt-out links above. To make a request, contact us.
Children's privacy
Calculators4.com is intended for a general audience and is not directed to children under 13. We do not knowingly collect personal information from children.
Changes to this policy
We may update this Privacy Policy from time to time. Material changes will be reflected by updating the "Last updated" date above.
