Fitbit's 150B hours of heart data

I wonder to which extent tracking data is really anonymized since users can still request to delete it, as described in the privacy policy [1].

> If you choose to delete your account, please note that while most of your information will be deleted within 30 days, it may take up to 90 days to delete all of your information, like the data recorded by your Fitbit device and other data stored in our backup systems. This is due to the size and complexity of the systems we use to store data.

I work for Fitbit. I don't speak for Fitbit, but the web page you cited does.

I don't see any claims to anonymize unshared data. I just see "We may share non-personal information that is aggregated or de-identified so that it cannot reasonably be used to identify an individual."

If it's anonymised well enough it wouldn't be possible to delete it, which may well be the case.
