Auto-Syncing?

[SunsetRunner]

Can someone please explain how - when I do not have "All Day Sync" turned on - every morning I see heart rate data on my dashboard? I am not manually syncing, All Day Sync is off, bluetooth is always off unless I need it, yet curiously, when I get into work and check my dashboard, I see this:

Could it be that one of your colleagues at work is a fellow fitbitter? 

If they have a computer with the software installed and wireless dongle in place your fitbit will happily sync via it when in range.

Thanks @SteveH, but no, the syncing happens before I leave the house. It isn't until I get to work that I notice it. I don't use the dongle, and my Windows 10 machine's bluetooth is always off - though who can say with Windows whether it's truely off.

It's a conundrum, to be sure.

I am having a similar problem and can't figure out how to stop it from auto syncing. My dongle is not connected, my bluetooth is off but it continues to sync.  I turned off all day sync so I am not really sure what is going on.  Would love any help!
