How do I stop receiving Oura data through Apple?

Other apps such as Oura write their readings into Apple HealthKit.

Other apps such as Oura write their readings into Apple HealthKit. Since the iOS SDK reads everything in HealthKit, that data is tagged as APPLE.

To filter it out, call the iOS SDK's Terra.setIgnoredSources([bundleId]) at SDK setup, passing the source's bundle identifier. Confirm the identifier from a sample's sourceRevision.source.bundleIdentifier.

Alternatively, the end user can:

1

Open Apple Health > Sources > the app.

2

Toggle off the data types it writes.

3

Optionally delete its historical samples.

See the iOS SDK reference for setup details.
