Concerned about Outgoing network connections

I read Budget Flow’s Privacy Policy but I still have questions.

These are the 4 connections that Budget Flow is trying to access:

1. googleapis.com > ???? [privacy page says firebase remote config / crash]

2. crashlytics.com > crash data?

3. budget-flow.app > ????

4. revenuecat.com > verification of purchase

RevenueCat is a payment service provided by RevenueCat, Inc. The service allows the Owner to monitor and analyze the User and their purchase history and can be used to keep track of User behavior.

Usage Data: Information collected automatically through this Application (or third-party services employed in this Application), which can include: the IP addresses or domain names of the computers utilized by the Users who use this Application,

I am not suggesting anything nefarious, but the app contains obviously personal details like purchases so I would ask this of any app.

Why can’t we have an option to turn off all of this extraneous data? I just want the app to communicate to iCloud for sync and that’s it. I wish the user had more control over this as it will for sure turn some privacy-minded folks away from the app.
