"if you wish to opt out of future collection of voice samples, you may do so by disabling voice-related features in the BoldVoice app. Please note that this may limit the functionality of certain services."

Yeah, I can opt out. By not using any voice-related feature in their voice training app.

If you're still actively using the app, the voice will be retained and processed so that you can receive instant feedback, and also so that you receive additional personalized practice items and video lessons based on your speech needs. If you don't want the samples saved "in perpetuity", you can request them to be deleted once you decide that you're done with the application. Hope this helps!
