This Privacy Policy explains how DateCalculatorFree ("we", "us", "this site") handles information when you use DateCalculatorFree's date-calculation tools. We built this site to need as little of your data as possible.
The dates and numbers you enter into the calculators are processed entirely in your browser using JavaScript and are never transmitted to, or stored on, our servers. We do not require or request an account, email address, or any personally identifying information to use the calculators.
Like most websites, our hosting and analytics provider may automatically log standard technical information, such as your approximate location (derived from IP address), browser type, device type, and pages visited, for the purpose of operating and securing the site and understanding aggregate usage.
This site may display advertisements served by Google AdSense. Google, as a third-party vendor, uses cookies — including the DoubleClick DART cookie — to serve ads based on a visitor's prior visits to this and other websites. Google's use of advertising cookies enables it and its partners to serve ads based on your visit to this site and/or other sites on the Internet.
Our advertising and analytics partners may operate their own privacy policies covering how they use information collected through cookies. We encourage you to review those third parties' privacy policies for more detailed information.
This site is not directed at children under the age of 13, and we do not knowingly collect personal information from children. If you believe a child has provided us with personal information, please contact us so we can address it.
Depending on where you live, you may have rights to access, correct, or request deletion of personal data held about you, and to object to or restrict certain processing, including personalised advertising. Because DateCalculatorFree's calculators don't collect personal data directly, most such requests will relate to advertising or analytics cookies — use the opt-out links above, or contact us with any questions.
We do not retain the dates you enter into any calculator. Aggregate, non-identifying analytics data may be retained by our analytics provider according to their own retention policies.
We may update this Privacy Policy from time to time. Changes take effect when posted on this page, and the "Last updated" date above will reflect the most recent revision.
Questions about this policy can be sent via the contact page.
