How do I stop Health from recording my data?

When I tap on the app icons, both Health and Fitness apps are at the Welcome pages, which means that there shouldn’t be any activity of mine being picked up, recorded, or shared.

I have never authorized, used, or shared any Health data. Instead, seeing everything it gathers, I tried deleting my iPhone from Devices, under Data Access and Devices in Health from the Settings. I’ve tried setting the Motion and Fitness toggle to OFF in addition to that. I deleted all data and set Health to OFF in iCloud. But every time I look again, Health is at it again, with my iPhone is back under devices (twice this time), under iCloud, Health’s toggle is back ON, and I must go and delete everything it gathered after I deleted my device however many times it’s there, and set the iCloud toggle to OFF again, etc.

I am not sharing any service, data, information, or app with anyone. I haven’t shared my passwords, passcodes, or devices with anyone. I live alone and no one has access to my devices.

What is the most concerning is that when I happen to try to do a Safety Check, I get a pop up saying « Unable to stop sharing in Fitness » « Stop sharing in the app directly » whileand I am not sharing and I have never used it either.

Does anyone know how to stop Health from recording my every step permanently, otherwise than what I’ve already tried unsuccessfully ?
