There are two approaches in the GDPR. The first one, which I already mentioned, relates to the right not to be subject to certain decisions unless there are safeguards. The second approach relates to transparency, and here we have a lot of novelties. This is an area where data options....will be equipped with more transparent, intelligible, concise, and easily accessible information and forms. There is a clear need to use plain language. Here we have another area where children are considered in terms of transparency—I forgot to mention this earlier.
These articles on transparency do not relate specifically to processing modalities, but by reading them in a global approach, you will understand that in the case of certain processing modalities that you mentioned, transparency should be reinforced and be effective in practice. This is largely for guidance by DP. There are some provisions concerning machine-readable icons and standardized icons, but I doubt they relate to the case you mentioned.
