Privacy Policy

What we store

D4BossTimer has no accounts and no server-side database. The world boss timer keeps a few preferences in your browser's localStorage only: notification and sound settings, alert lead time, 12/24-hour clock, time zone, and your weekly Grand Cache check-marks. This data never leaves your device and is deleted when you clear site data.

Notifications

Browser notifications are optional and only enabled when you click "Notify me" and accept the browser prompt. They are generated locally by the page; we do not run a push server.

Advertising

The site reserves space for third-party advertisements (for example Adsterra). When ads are enabled, the ad network may set cookies or collect usage data under its own privacy policy. We do not share any data we store with ad networks, because we store none on our side.

Analytics

Hosting-level, cookie-free traffic statistics may be collected by our hosting provider (Cloudflare).
