Privacy policy

Last updated October 24, 2026

The short version

You do not need an account to use DayReckon, and the dates you type are calculated in your own browser. They are not sent to us. When you change a calculator, the page address updates with your inputs so you can bookmark or share the result; that address stays in your browser unless you share it.

Information collected automatically

Like most websites, our hosting provider (Cloudflare) processes basic technical information when you load a page, such as your IP address, browser type and the page requested, in order to deliver the site and protect it from abuse. We may use aggregated, anonymous statistics about which pages are visited to decide what to improve.

Advertising and cookies

We use Google AdSense to show advertisements, which keep the site free. Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this website or other websites. Google’s use of advertising cookies enables it and its partners to serve ads to you based on your visits to this and other sites on the internet.

You can opt out of personalized advertising by visiting Google Ads Settings, or opt out of some third-party vendors’ use of cookies at aboutads.info. To learn how Google uses information from sites that use its services, see How Google uses information from sites or apps that use our services.

Where advertising is shown, visitors in the European Economic Area, the United Kingdom and Switzerland are asked for consent before personalized ads are used, through a consent message that meets Google’s requirements.

Your choices

You can block or delete cookies in your browser settings. The calculators keep working without cookies.

Children

This site is meant for a general audience and is not directed at children under 13. We do not knowingly collect personal information from children.

Changes and contact

If this policy changes, we will update this page and the date above. Questions about privacy can be sent through our contact page.
