Data we use and why
Browsing this site and adding the calendar subscription currently require no account or email address.
Cloudflare hosts this site. To deliver pages and protect the site, its servers may receive your IP address, request time, URL, and browser information. Our region API uses Cloudflare's country code only to choose which consent notice to show. Its response is not cached, and we do not store that code in a site database.
When Cloudflare Web Analytics is enabled, Cloudflare receives site use data such as the page URL, referring URL, and browser information to report aggregate traffic. It does not use analytics cookies.
Once a GA4 property is configured, this site loads Google Analytics 4. It may receive page view events, page URLs and titles, referring URLs, and browser and device information to help us understand readership and improve the site. Analytics storage is denied by default; Google may still receive cookieless signals when you decline. Analytics cookies are allowed only after you agree. We do not use advertising cookies, Google Signals, or personalized ads.
Cookies and browser storage
| Name | Purpose | Retention |
|---|---|---|
| _ga | Google Analytics distinguishes browsers | Up to about 2 years, subject to Google settings and browser limits |
| _ga_* | Google Analytics maintains session state | Up to about 2 years, subject to Google settings and browser limits |
These analytics cookies apply only when GA4 is configured and you agree. Cloudflare Web Analytics sets no analytics cookie. We also keep hb-analytics-consent (your choice) and hb-theme (your color preference) in localStorage until you change them or clear site data.
