SECTION 2: APPLICABLE LEGAL FRAMEWORK
2.1. General Data Protection Regulation (GDPR)
Regulation (EU) 2016/679, directly applicable in all European Union Member States since May 25, 2018, establishes the fundamental legal framework for the protection of natural persons with regard to the processing of their personal data.
In accordance with Article 4.11 GDPR, "consent of the data subject" means any freely given, specific, informed and unambiguous indication of the data subject's wishes by which he or she, by a statement or by a clear affirmative action, signifies agreement to the processing of personal data relating to him or her.
Article 7 GDPR establishes the conditions for consent, requiring that:
- The controller shall be able to demonstrate that the data subject has consented to processing of his or her personal data
- If the data subject's consent is given in the context of a written declaration which also concerns other matters, the request for consent shall be presented in a manner which is clearly distinguishable from the other matters
- The data subject shall have the right to withdraw his or her consent at any time, it being as easy to withdraw as to give consent
- When assessing whether consent is freely given, utmost account shall be taken of whether the performance of a contract is conditional on consent to the processing of personal data that is not necessary for the performance of that contract
2.2. Spanish Data Protection Law (LOPDGDD)
Organic Law 3/2018, of December 5, on Personal Data Protection and guarantee of digital rights, complements and develops the GDPR in the Spanish legal system. This law establishes specific provisions for data processing in certain sectors and situations, as well as a catalog of digital rights.
Article 6 LOPDGDD regulates processing based on the consent of the data subject, establishing that:
"1. In accordance with Article 4.11 of Regulation (EU) 2016/679, consent of the data subject means any freely given, specific, informed and unambiguous indication of the data subject's wishes by which he or she, by a statement or by a clear affirmative action, signifies agreement to the processing of personal data relating to him or her.
2. When the processing of data is intended to be based on the consent of the data subject for multiple purposes, it shall be necessary for it to be specifically and unequivocally stated that such consent is given for all of them."
2.3. Anti-Money Laundering Law (Law 10/2010)
Law 10/2010, of April 28, on the prevention of money laundering and terrorist financing, imposes on obliged entities—among which CUANDEORO is included due to its activity of intermediation in real estate transactions with crypto-assets—a series of due diligence obligations that necessarily involve the processing of clients' personal data.
⚠️ IMPORTANT - LEGAL OBLIGATION TO RETAIN DATA:
In accordance with Article 25 of Law 10/2010, CUANDEORO is legally obligated to retain documentation related to the fulfillment of due diligence obligations for a period of TEN (10) YEARS from the termination of the business relationship or the execution of the transaction.
This means that your identification data (KYC), copies of identity documents, information about transactions carried out and any other documentation related to the prevention of money laundering will be retained for a minimum of 10 years, regardless of whether you request the deletion of your data.
Article 25.1 of Law 10/2010 textually states:
"Obliged entities shall retain for a period of ten years the documentation formalizing compliance with the obligations established in this law, proceeding to its deletion thereafter. After five years from the termination of the business relationship or the execution of the occasional transaction, the retained documentation shall only be accessible by the internal control bodies of the obliged entity, including the technical prevention units, and, where applicable, those in charge of their legal defense."
