Does they keep In confidentially our own data? (like name, second name, own info from social network)?
During the final stages of us processing your data, we are going to anonymize it. That means this sort of information will not be present in the final analyzed data batch that we are going to be selling. So you don´t have to worry.
When you say 'anonymize', do you mean all personal data like age, sex, location will be removed from the equation or do you mean, it will be anonymized on the count that it will remove the name and be clubbed along with data from other people into a category of people?
it means it cannot be traced back to you if you decide to sell your own data, so yes they remove anything that can lead to the owner
As Makkara is saying, we will remove all the personal identifiable data that could be traced back to you.
So, actually.. in short : All data EXCEPT personal data will be sold... but some data like age, gender, .... is needed for the buyers to have a correct analysis?
So... in fact, some personal data will be sold, the buyers just won't know who's personal data it is... so basicly, this is marketing research without giving out private info, no?
