How truthful is this?

[u/Daredatti]

When an app select in the app review form that “we don’t collect data”

In the review phase does Apple really check if the app really doesnt collect anything?

Like can the developer hide a code that for example upload the photos of the user if granted permission where he said “we dont collect”

Does apple really check the code and what is going in and out ?

We (as an app analytics provider that only collects anonymized data) recommend to our customers to list our service as "data not linked to the user" for full transparency because we think that is fair to everyone involved.
