iPhone Analytics Data - Unable to delete

I have the following questions relating to iPhones Analytics Data and my privacy.

1. What applications, websites, web browsers and third-parties can access my Analytics Data when all options (‘Share iPhone Analytics’ , ‘Improve Siri and Dictation’ , and ‘Share iCloud Analytics’) have been turned off (as shown in attached image below)?

2 . What iPhone stored Analytical Data can be used to:

a. Identify myself

b. Monitor my activity and interactions with others

c. Identify my location

d. Be used to correlate information to identify myself specifically or implicitly?

3 . Is any of the iPhones stored Analytical Data accessed/transferred/uploaded/saved to Apple (or it’s subsidiaries), or any other application, program, or third-party when I connect my phone to any of Apple’s applications (iTunes inclusive)?

4 . How do I delete all iPhone Analytical Data on my iPhone without having to connect to iTunes or any other application without having to do a complete phone reset?

Apple markets itself about users having ‘control of what you share’ (https://www.apple.com/au/privacy/control/) and I hope they are willing to honour this statement.
