Can anyone answer me? how long are copies of our data retained on their platform?
If it is stored on a blockchain (which i think it is), that would mean it can never be deleted. But it would be encrypted and possible stored (in pieces) over multiple nodes, so it should be safe
But if I will want to delete my data? How I can do this?
You can't, but you can encrypt it so that no one but you can access it. Kinda like writing it on a piece of paper and burying it somewhere only you know
It is encrypted by default, isn't it? And if we sell some data I guess the data gets pulled from the chain decrypted and then transferred to the buyer.
Yes exactly. I wonder however what someone could do with the data he bought, like if someone sells his data to one person specifically, does he transfer the rights to that data so that the buyer can spread that info without repercussion? Maybe the buyer has to sign a clause stating that spreading the info leads to permanent banning, heavy fines and legal persecution, like when a doctor would spread sensitive info about his patients
That's a very good point. Companies like Google wouldn't resell data because they want to know more than the rest but if some shady "information broker" buys data relatively cheap they could try to resell it; especially if prices for data fluctuate.
Official they will probably use be allowed to use your data for their own research etc and not to sell it, but honestly, who will control this? No one probably and you will also never know who will buy your data from whom as you at the moment also don't know who will buy your data from Facebook or Google or whoever.
