Tracking Transparency - clarification on when asking for permission is not required

We're building a modern analytics tool for mobile apps.

I personally applause to iOS 14 privacy changes but on the same hand, I'm a little bit worried about opt-in system for tracking as early surveys suggests most users won't opt-in.
We'd love to build a tool that both respects privacy in Apple's spirit and gives developers a broad perspective on their business performance.

I'd love to hear more clarification on cases where we don't have to ask for permission for "tracking"?

Here are a few of gray area cases.

Case 1

Do we need to ask for "tracking permission" if:
1) user's activity data is uploaded to the 3rd party analytics tool
2) users can be identified with email and/or identifiers
3) BUT it's only used for developer's business analytics and is NOT SOLD OR USED for advertising?

In that case, 3rd party is solely providing a product to persist and analyze the data on developers behalf and it's not selling that data to anyone.

Case 2

Do we need to ask for "tracking permission" if:
1) user's activity data is uploaded to the 3rd party analytics tool
2) BUT we're only using anonymous identifiers generated on-device that can't be linked to the device?
For example, we generate a new UUID on first app launch and use it to "identify" the user. No ID for Vendor is used.
