Transparency is a big part of the reason that the GDPR was passed by the European Union. It's a lot about consumer rights, making sure that consumers know how their data is being processed, what data is being processed, and what you do with that information once you have it. A lot of it surrounds some less special interest categories of data, like emails, names, addresses, employee information, or other information about your employer that could be used to identify you. All of that is covered by GDPR. And so, as part of making sure that you're being transparent, you need to inform the consumer or data subject in advance that you're collecting this data, exactly what you're doing with it, how it will be stored, how they can ask it to be amended or removed. Explicit consent must also be given by the data subjects.
