Is my music used to train AI models?

No. Your music is never used to train any AI model, ours or anyone else's.

When you turn on AI tagging, Songbox listens to a track only to describe it, then discards it. Analysing a track and training a model are two different things:

• Training is when a model studies huge amounts of music and permanently absorbs it.
• Analysis is when a finished model listens to one track and simply reports what it hears.

Songbox only ever does the second. Your track is never added to a training set, never used to improve a model, and never kept by the AI once its tags are written.
