I've been researching about the GDPR on the internet to find an answer to my question, but I have not found a concrete answer.
Does the GDPR allow me (my software/server) to derive data, store it and use it for any purpose?
For example: perform an analysis of a person via their ex: (twitter feed) and store the analysis. All of this without needing to inform the person of the analysis or them having the right to transfer/remove/get a copy of the analysis from me(my software/server)?
Could a loophole be to perform the analysis and store only the "connections"? Almost like giving a person a mathematical function without any plotted data, You give the end user a pre-made "template" (the analysis report) that they fill out by fetching the feed themselves?
