To any iOS users worried about Niantic banning their account if they ask for a refund:
I found an old reply from Apple to an app developer asking if they could get a user's information after a refund - this basically confirms Apple DOES NOT provide that info when requested:

"Thank you for following up with me regarding the refund transaction data.
We will not be able to provide you with the refund transaction data you have requested as it is not a feature or benefit provided to you per the contracts you have agreed to.
To view your paid applications contract and review your membership benefits, please access the contracts, tax and banking module within iTunes Connect:
http://itunesconnect.apple.com
If you are not happy with large refunds, you may want to consider adjusting the price of your in-app purchases as we will not be able to provide you with the refund transaction data in the future."
