This Extension does NOT collect ANY User Specific Data.
for example: email-addresses, passwords, names, URLs of pages you visit.

This Extension does NOT create a user profile from your activity.

This Extension ONLY runs on the domain *.soundcloud.com/*

However the Extension sends information about the tracks downloaded.
(this is required for its main task: adding meta data to the downloaded tracks).

In certain instances the names of the Soundcloud artist profiles you visit will be sent to the server.
