Website analytics

On our production website, we use Vercel Web Analytics to understand which public pages people visit and improve the experience. It reports aggregate visits, referring websites, approximate location and browser/device information without analytics cookies.

We remove all query parameters and fragments from page-view URLs before sending them. City-specific timing paths are grouped by tool so their city and date are not sent. Embedded widgets, CMS, authentication and API pages are excluded. We do not send birth details, form answers, passwords, authenticator codes or custom events to analytics.

See Vercel’s analytics privacy information for its visitor identification and data handling.

Preferences on your device

The app saves your selected place, calendar and theme in your browser. Its offline cache stores app files and supported calendar data. Clearing this website’s browser storage removes these saved preferences and downloaded files.

Sharing and calendar reminders

Reminders are prepared locally as a calendar file. You choose whether to download and import it; your calendar provider then handles the imported events. Copy and share controls act only when you use them. Public timing cards include their city and date. Embedded web widgets show public calculations and do not request location permission or collect birth details.

Signing in and publishing

Sign-in uses security cookies. The private publishing desk stores content in our GitHub repository and requires administrator authentication. Do not include sensitive personal information in public posts.
