What Info does producer collect?

Remember that this is only true if you are on the free tier of JUCE. GPL and paid for licenses don’t phone home - you can simply disable it in the Projucer.

In your case, where you have “very protected (IP) code”, you are not allowed to use the GPL license.

Also, we are very open about this - this was all discussed at great lengths in other forum posts.
