KEKW Blocker is a Twitch-focused browser extension. It does not require an account and does not collect, sell, or share user data for analytics, advertising, profiling, or resale.

To perform its core function, the extension processes Twitch page and player data locally in the browser, including Twitch page URLs, channel identifiers, player state, media playlist responses, and request metadata needed to request backup streams and recover playback.

The extension transmits only the data necessary to function:
- requests to Twitch endpoints used for playback and recovery
- requests to Twitch media playlist endpoints used to compare and switch stream variants
- periodic requests to a signed remote configuration file hosted at dorquex-ctrl.github.io

The extension stores the following locally in browser storage:
- user options
- global enabled or disabled state
- cached signed remote configuration
- temporary runtime-learned Twitch request values used for recovery
- learned backup-player ranking data

The extension does not include analytics, telemetry, crash reporting, advertising SDKs, payment processing, or account creation.

As part of normal HTTPS requests, Twitch and the remote configuration host may receive standard network metadata such as IP address, user agent, and request timing, subject to their own privacy policies.
