How do privacy and app permisions relate?

[TsengSR]

How is the claim of data privacy relating to the permissions asked in the app itself on app store??

Like "everything is stored locally" vs

Why is data shared with other companies and organizations, if the data is supposedly stored locally on the phone only?

Also why does the app need to collect email? Developer communication can't be, for that you'd provide a link (with YOUR Email) and it opens in your favorite mail app where the sender it sent from. There is no technical need why the app needs access to email at all!

Would love to hear why these are required and in contrast to the claims that everything is stored locally and your plans to address these and remove the permissions in question.
