Does Sync.com train on your data?
Sync.com sells end-to-end encrypted storage. Its privacy policy mentions training once, and it is about staff.
The single occurrence of "train" is Sync having "trained its staff" on its own privacy practices — a governance statement, not a use of your files. No "machine learning", no "artificial intelligence", no bare "AI". Unlike its competitors on this list, Sync markets zero-knowledge encryption heavily; the policy captured here does not make that a capability claim in terms this site can grade, and says nothing about training either.

The single "train" hit is "trained its staff", which is about Sync's own people. Counted so the zero can be checked.
