Well you may jest, but …..
Never having had a Fitbit, I have no idea how data storage, retrieval, etc works, but that's actually not far off what I'd find acceptable.
I am quite capable of (and do, for other data series) track my own data in either spreadsheet or database. I can get all the analysis I want/need that way.
However …. my concern, given the apparent plethora of data types, volumes and granularity of fitbit data, is transcription. I'm not going to manually enter dozens, or hundreds, of values daily, but if I can export in some understandable format, and import (say, weekly) then I'm capable of extracting the metrics I want.
But I have a sneaky feeling Fitbit won't allow that. Unless sonebody knows otherwise.
That's why I suggested a device where the control software runs
locally, which on a system with no net connection lets me guarantee privacy. But there are NO circumstances where I'm prepared to even risk a private company getting such personal biometric data about me as a fitbit would provide. Not this side of the end of the universe is that happening. I'd rather adopt Win 10 and use Google for searches.
