Suno
Suno trains the models behind its music generator on what you submit and type, under legitimate interest — without ever using the words "AI" or "machine learning".
Verdict
F
- Trains on you by default
- No opt-out in the policy
- On by default, with no way out on the plan you are on — and nothing short of reading the terms would have told you.
