Black Mirror Browser (the "Extension") is a Chrome extension by kinoshita studio. It opens BMBoard (an infinite‑canvas blackboard at bmboard.studio) as a browser side panel, and adds a right‑click menu to send images and text to the board. This page explains what data the Extension touches.
The Extension does not collect, transmit, sell, or share any personal data. There is no analytics, no tracking, no account, no server run by us.
