How we read it: The phrasing is a purpose list rather than a declaration, and "may include" is doing work — but what it may include is generative AI models developed from the information described in the same sentence. On a device worn continuously that information is resting heart rate, sleep stages, menstrual cycle logging and where you ran. No opt-out is named anywhere in the document, and no plan is described on which this does not apply.

How to opt out of Fitbit AI training
Plan by plan, from what Fitbit's own policy says about refusing. Where it publishes the steps, they're listed here with the limits they carry. Where there's nothing to switch off, or nothing graded, this says so instead of inventing a menu path.

No opt-out is stated in the policy on file for Fitbit.
What this policy has done since we started watching
No change detected. We've held a copy of Fitbit's policy since 30 Aug 2026 and re-read it since, across 2 captures. The text hasn't moved in a way that touches this verdict. That's a fact about the document, and it's only knowable by having kept the earlier copies.
Everything we read
Vendor response
We wrote to Fitbit on 31 Aug 2026, quoting the clauses above and inviting a correction. Nothing has come back. That's published because a company declining to comment on its own policy is something a reader should know, and because the invitation should be on the record whether or not it's taken up. Any reply goes here, word for word.
