Serial Numbers and staying off the grid

[YOUSER]

What can be done, if anything, remotely with a Mavics serial number?

If one was to fly the Mavic without a phone connected, just RC, will there be a record of this flight anywhere other than the Mavic's own flight log?

As a first time DJI product owner, I'm trying to understand how their systems work.

I saw some flight logs on my phone and deleted them just so I could see if they re appear. They haven't yet and my total flight time and all those other stats have gone. Will they come back once I hit the sync button? Do they automatically sync to the cloud whenever connected to the internet?

Thanks

The answer is not simple because DJI has been exposed for suspicious app activity, and has since made efforts to avoid this bad public relations by making changes to recent app versions. I wish I could offer you more information. Suffice to say that I simply do not allow my phone to ever go online for any reason, once I have DJI app installed. If for some reason I do need to go online, I wipe the phone to factory first, as it takes very little time to do and removes all doubt.

Every item has somewhere around one approach to acquire the item model and sequential number, and now and again 2 or even 3 distinctive approaches to get this data.
