Sky Shard (skyshard.day) is a static, single-page tool. There is no account system, no server-side database, and nothing you do on this site is sent to us or stored on any server we control.
If you turn on a 🔔 reminder for a shard eruption, reset, or Traveling Spirit departure, that preference — and the browser's notification permission — is stored only in your browser's local storage. It never leaves your device and we have no way to see it.
Reminders use your browser's native Notification API. They only fire while this site is open in a tab — this is not a push service, and no data about your subscriptions is transmitted anywhere.
This page loads fonts from Google Fonts (fonts.googleapis.com / fonts.gstatic.com), which means your browser makes a direct request to Google's servers to fetch them — Google's own privacy policy governs that request.
We use Google Analytics (GA4) to see aggregate traffic — things like page views and rough visitor counts — so we can tell if the site is useful. Google Analytics uses cookies and collects data such as your IP address (which Google may use to approximate your general location), browser and device type, and pages visited. It does not receive your shard/reset/Traveling Spirit notification preferences, since those never leave your device. See Google's Privacy Policy for how Google handles this data. We don't run any other analytics, ads, or tracking scripts on this site at this time.
