That means data privacy and Germans are notoriously big on that, as you well know.
Take Germany’s planned reconnaissance flights over Syria and Iraq, for instance. Germans are so concerned about data privacy that they are already planning not to share the intelligence they might gather there with their allies. Sicher ist sicher (better safe than sorry).
The aircraft are expected to operate from Incirlik airbase in southern Turkey, and as Nato allies, the two countries would normally expect to share intelligence. But German commanders are concerned Turkey may use surveillance information from the flights to direct attacks against Kurdish forces allied to the West.

In light of who is running Turkey right now, not sharing information might be a sensible course of action.
