Privacy Policy

D-Day Calculator (the "Service") respects your privacy and processes only the minimum information described below.

1. Information we collect

The Service works without an account or login. The titles and dates you enter are calculated only in your browser and are not sent to our server. D-days you save are kept in your browser’s local storage on your device (up to 10), and you can delete them at any time. When you copy a card link, the title, date and card style are written into the link itself and are shared only with the people you send it to.

2. Cookies and similar technologies

The Service may use cookies and your browser’s local storage to remember your language and saved D-days, to show ads and to understand how the Service is used. You can refuse or delete them in your browser settings; some features may not work as expected if you do.

3. Advertising (Google AdSense)

The Service shows ads through Google AdSense. Google and its partners may use cookies to serve ads based on your previous visits to this and other websites. You can learn more and change your preferences in Google Ad Settings.

4. Statistics

To improve the Service we may use Google Analytics (GA4) and our own aggregate counters that keep only daily totals per language (page views, calculations, star ratings). Your titles and dates are never part of these counts, and none of this identifies you personally.

5. Contact

If you have any questions about this Privacy Policy, please contact the site operator.

6. Effective date

This policy is effective as of October 17, 2026.
