Privacy Policy

June 19, 2026

1. Absolute Privacy Commitment

BlockX is built from the ground up to be a privacy-first tool. It operates exclusively as a local browser utility. We do not collect, monitor, log, scrape, or transmit any tracking records, network traffic data, or personally identifiable information.

2. Local Storage & Rules Execution

Any configurations you create—including custom domain blocklists, explicit keyword filtering strings, and operational toggles are saved strictly on your local machine using the browser's native sandboxed storage API.

Network filtering actions are evaluated directly by your browser's internal engine via the native declarativeNetRequest API. No data or request streams are ever transmitted to external servers or third-party analytical systems.

3. Third-Party Data Transference

Because BlockX does not collect or access your personal data, no information is ever captured, processed, sold, commercialized, or transferred to third-party entities, advertisement networks, or data brokers.
