Privacy Policy

Last updated: September 4, 2026

1. Information We Collect

You can use the site without creating an account or submitting personal details. Calculator inputs are processed in your browser and are not submitted as calculation requests. Like every website, our hosting and content-delivery providers receive technical request information such as IP address, browser details, requested URL, and timestamps so they can deliver and protect the site.

Some tools can create a shareable link. When you create or open one, its selected dates, times, title, or settings are encoded in the URL and are therefore visible to anyone who receives the link and to the systems that deliver the page. Do not place sensitive information in a countdown title or shareable URL.

2. Cookies

Your dark-mode preference is saved in your browser's localStorage. Google AdSense may use cookies or similar storage to display and measure advertisements, subject to your choices. Where required, Google provides the consent controls used for those choices. We do not use Google Analytics or Facebook Pixel. See Section 3 for the analytics service we do use.

3. Third-Party Services

Google AdSense — we use Google AdSense to display advertisements. Google may use cookies and web beacons to serve ads based on your prior visits to this or other websites. You can learn more by visitingGoogle's Privacy Policy, and you can opt out of personalized advertising viaGoogle Ads Settings.

Umami Analytics (self-hosted) — we use a self-hosted instance of Umami at stats.admk.com to understand page-level traffic, referrers, countries, browsers, and device types. It is configured without analytics cookies and with URL query strings excluded, so values placed in shareable links are not included in analytics page URLs. The resulting reports are used in aggregate and are not used for cross-site advertising profiles.

4. Data Storage

Ordinary calculations are performed locally in your browser using JavaScript and are not saved to an account or calculator database. Shareable links are the exception described in Section 1: their settings travel as part of the URL when the link is opened. Technical server, CDN, analytics, and advertising data may be retained according to operational needs and the applicable provider policies.

5. Children's Privacy

Our website is not directed at children under the age of 13, and we do not knowingly request personal information from children. Visitors should not put a child's personal information into a countdown title or other shareable URL.

6. Changes to This Policy

We may update this Privacy Policy from time to time to reflect changes in our practices or for legal, regulatory, or operational reasons. When we make changes, we will update the "Last updated" date at the top of this page. We encourage you to review this policy periodically.
