The open-source software is now collecting user data for "app analytics" and "improving our app" as well as "for legal enforcement."

Muse Group is collecting details about users' operating system version, processor, country based on IP address, crash reports and non-fatal error codes and messages. According to the policy, processing that data is in the "legitimate interest" of the company "to offer and ensure the proper functioning of the app."

The data it collects on law enforcement grounds is more vague. The policy says Muse Group will capture "data necessary for law enforcement, litigation and authorities' requests (if any)." It may share personal data with "any competent law enforcement body, regulatory, government agency, court or other third party where we believe disclosure is necessary." Data may be shared with potential buyers too.

To be short - software sends parts of all audio files for recognition and mark any file that has copyright owner. After this they sell this information in big batches to such owners to allow them to get big money from them. Main target for attacks are firms and individual workers with significant income who can use file without authorization or with wrong license. Before it was impossible to track this if you do not upload result to big online platform, but now offline software will track all of your actions and sell all this info to anyone who will pay for it.
