Limits of the analysis

The analysis shows code inside the app file, not data transfers: an SDK being present means a transfer is possible, not that it happens. The country is where the company owning the SDK is registered, not where its servers are. Some code may have been renamed at build time, so the SDK list is a lower bound.

The legal assessment is made by the competent supervisory authority.
