From what I understand, and keep in mind that I don't work for Fitbit, the data is preserved indefinitely and not deleted from Fitbit's server.
For instance, I have data going back to 2/28/2011, and I'm able to retrieve the daily data, and intraday data. Also, in my dissertation research I enrolled a participant who had data going back to December 2009 (this participant was an early pre-orderer of the original Fitbit), and was able to access their data using our Fitabase data management platform.
Hope this helps!
Best AnswerHi,
I can help with this. You can view the relevant help page here on syncing devices. The important point is:
A daily sync is recommended but not required. Most Fitbit trackers record detailed minute-by-minute data for seven days. (Fitbit Alta records minute-by-minute data for five days). Fitbit trackers can store daily totals for up to 30 days.
When working with researchers we typically recommend they have participants sync devices every 5 days just to make sure there is a bit of wiggle room in there. It is very important to sync at least once every 7 days for access to minute-by-minute data for steps, activity intensity, and energy expenditure, as well as second-level heart rate data, and sleep logs. Sleep data particularly important as it is processed at Fitbits servers and needs to have access to that higher resolution data to create sleep logs.
Hope this helps. If you have more questions about using Fitbits in research, or how you can easily access Fitbit data from
