How to delete Health data in iCloud only? So, I've decided not to store my health data in iCloud anymore, for various reasons. I just want to have it on my iPhone and on my iPhone backup on my Mac.
Here's what I have tried so far:
So I turned off Health in iCloud on my iPhone and hoped it would delete all the Health data from my iCloud account. It didn't though, here's a screenshot:

It seems like it only stopped backing up new data but the old data remains online.
So I tried to delete it via the iCloud settings on my Mac, which gives me this prompt:

(Note: There is no Health folder in Finder iCloud Drive).
Is it safe to click delete or will it also wipe all my data from my iPhone and Apple Watch Health apps?
And if this operation deletes it everywhere, where can I delete it on iCloud only?
Health Syncing in iCloud will not appear in iCloud Backups or in iCloud Drive. It is stored directly in iCloud rather than in iCloud Drive or other sub-service.
If you turn off the Health switch on your phone, then you have disconnected the local Health repository from the cloud. You can safely delete your Cloud health data after doing this.
Health data is stored End-to-End encrypted, unlike backups. The article you linked to refers to iCloud Backups, a different system. When you turn off the Health switch, it will start backing Health up to the non-end-to-end encrypted iCloud Backup. You must also turn off the Health feature in iCloud Backup to avoid this.

The phrasing on the Mac is different and likely flawed. The same delete button you've shown on the phone makes it clear that you're only deleting it in iCloud, not per-device.
