In terms of data protection, we must take into account the provisions of both the GDPR and the LOPDGDD. The GDPR establishes that the processing of personal data of data subjects must be lawful, and for this purpose, it must be based on any of the legal bases provided in Article 6, with consent being the most common one. This consent must be a freely given, specific, informed, and unambiguous indication of the data subject's agreement to the processing of their personal data, either by a statement or a clear affirmative action. The consent of the data subject must be given separately for each purpose of the processing. The data subject has the right to withdraw their consent at any time, and withdrawing consent should be as easy as giving it. The GDPR also provides, in Article 13, the duty of information, which means that, at the time when data is collected, the following information must be provided to data subjects, among others:
The LOPDGDD, on the other hand, establishes in its Article 11 that the duty of information may be fulfilled by providing the data subject with basic information and indicating another means that allows easy and immediate access to the remaining information. The basic information must include, at least, the following:
Furthermore, it is required that the information be provided in a concise, transparent, easily accessible manner, and in clear and simple language. All of the above means that, prior to processing personal data, the consent of users must be obtained. This consent must be freely given, specific, informed, and unambiguous. In addition, users must be informed of the terms and in the manner mentioned above, and the consent of users should be as easy to withdraw as it is to give. To achieve this, it is common to use the formula provided by the LOPDGDD, which was also recommended by the AEPD in its September 2018 report on Privacy Policies on the Internet. This formula is based on the following principles:
