Privacy

What BLACKOUT DESK collects and how it handles your data.

Data Collection

  • BLACKOUT DESK runs entirely locally on your machine.
  • No user data, IP addresses, or browsing behavior is collected or transmitted.
  • The connectivity check runs in your browser and results stay local.
  • Push notification subscriptions are stored locally in your SQLite database only.

External Requests

  • The ingestion worker fetches public data from IODA, Cloudflare Radar (if configured), and public status pages.
  • The local connectivity check pings well-known public endpoints (Google, Cloudflare, Apple, Microsoft) using no-cors mode — no identifying information is sent.
  • All fetched data is stored locally in SQLite.

Offline Snapshots

The "Save offline snapshot" feature stores dashboard state in your browser's localStorage. This data never leaves your device.
