This linked post doesn't say anything about Google Calendar.

It's not necessarily that I doubt you, it's just that the press release is pretty specific that consumer GMail isn't going to be used for ad customization from now on, and it seems like if it was everything in G-Suite that would be mentioned somewhere.

I don't suppose there's a list Google maintains anywhere online that shows which of their own products they use to aid with ad targeting?
