Is Celonis Task Mining Browser Extension safe?

Low risk

Celonis Task Mining captures clicks, clipboard text, and form input on every page and sends them to a local desktop client over a WebSocket.

The extension's content script watches every page you visit for clicks, double-clicks, copy/cut/paste, text selections, and changes to non-password form fields, and can also pull specific page elements using admin-defined selectors delivered from the desktop app. Each captured event is passed to the background service worker, which forwards it over a local WebSocket connection (ws://127.0.0.1:8080) to the Celonis Task Mining desktop client whenever recording is enabled - a setting the extension turns on by default each time it starts. Password fields are excluded from the captured values.
