Missing Sleep Data

[Michael-L]

I rarely sync my watch to my account but when I do I want to look at the historic sleep data, however the entire month of June and most of July are missing. I wear my watch every night and make sure its charged and despite it giving me a dead arm during the night quite often I still wear it because I find the data useful.. 

Is my data lost forever?

Thanks

If you've synced and it's not there then I'm afraid it's not going to appear.

I think the problem is that fitbits only have limited capacity to hold data in between syncs. It varies between trackers and the type of data but, roughly, they only hold up to a week's detailed data.

As you rarely sync I would suspect that your tracker ran out of storage. It would be ideal to sync at least every few days.

Sadly it doesn't sync at all now. It's a fitbit 2,since the latest app update there is not even an option to sync.. Maybe they ha e discontinued supporting the device.
