Fitbit Oura
Fitbit's policy answers the question and is graded F. Oura's doesn't say either way. That's a finding about the document, not a worse grade.
Fitbit
Fitbit uses the information it collects to develop new features "which may include generative artificial intelligence models". It holds heart rate, sleep and location.
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.
- 5 Oct 2026
Oura
Oura's policy puts its own use of your data under a heading that says "Large Language Model Training", and rules out only selling it for somebody else's LLM. Whether it trains a model, it never says.
Verdict
- The policy does not say
- Nothing to opt out of on the record
