Samsung did something similar with their phones' built I'm heart rate and oxygen sensor, and health related metrics from the accelerometer
My Samsung Galaxy S8+ had those sensors and I used them often for many years. The results were interesting and useful, and graphed with history in the Samsung app which shipped on the device.
Then one day they changed the terms so you had to create and sign into a Samsung account, and upload your health data, to continue using the sensors.
I didn't accept those terms so I wasn't able to use those health monitoring functions on my expensive device any more.
Interestingly, most articles I saw about the change portrayed it as a good thing, that you could now have consistent healrh sensor records across your devices and other good cloud features, even portraying it as an oddity that Samsung Health didn't require Samsung cloud integration all along and that they had finally caught up to the times. But it already had those features before the change! The only visible change was to to remove the choice to opt out of uploading your personal data.
