  1. Who has access to your personal data?
  • Our authorized personnel will have access to your personal data on a need-to-know basis. These individuals have undergone a background investigation before being hired and are required to treat the information as highly confidential.
  • Additionally, we may contract with third party service providers to provide ancillary services. If and to the extent such parties come into possession of your personal data, they will act as our data processor. These are, for example, cloud service providers and providers of certain software solutions. We will enter into a data processing agreement with such parties, which will include data security provisions to protect your personal data from potential data breaches. These data processors will only process your personal data to the extent necessary for the provision of the services for which they have been engaged.
  • We may also share personal data with affiliates who have referred you to our website, and with partners for promotions or integrations of co-branded services.
  • We may provide your personal data to competent authorities upon request to the extent required by law or to the extent necessary to defend our rights in legal proceedings or investigations.

In addition, we reserve the right to disclose your information to other users, entities and/or authorities when there are sufficient grounds to consider that your activity was suspicious and/or there is a reasonable presumption that other people could be harmed.

  1. Is your personal data safe?

We use technical and organizational security measures to protect our customers’ personal data against loss, theft, misuse or unauthorized access.

This means that we will take appropriate technical and organizational measures to ensure that all information is correct, up-to-date and complete, and to prevent unauthorized persons, inside and outside our organization, from accessing it. We use “best practices” to protect your personal data. For example, your personal data is encrypted with SSL (Secure Sockets Layered) technology and our directories and databases are password protected.

  1. How do we transfer personal data internationally?

Due to the nature of the services we offer, it is necessary to use servers and cloud services, which may mean that some of the personal data we collect is stored or processed in countries other than the country of origin.

Where personal data is transferred to a country that does not provide an adequate level of data protection in accordance with applicable law, we will implement additional technical and/or organizational security measures to ensure the protection of your personal data. If necessary, we will require the service provider to also implement these measures or supplement them with appropriate measures.

These guarantees may include the use of binding corporate rules, contractual clauses adopted by a supervisory authority or contractual clauses authorized by a supervisory authority. These measures seek to ensure compliance with personal data protection regulations and guarantee that interested parties have enforceable rights and access to effective legal remedies.

  1. About operations carried out on blockchain

Blockchain technology operates as a shared, immutable record that facilitates the process of recording and tracking transactions and assets, both tangible and intangible. Anything of value can be tracked and traded on a Blockchain network, reducing risks and costs for all participants.

This technology generates an ever-growing list of records called blocks. Each block contains a cryptographic hash of the previous block, a timestamp, and other data related to the transaction. Immutability is one of the key features of Blockchain: information stored in a block cannot be added, deleted, or modified without affecting the hash value and altering subsequent blocks. Once a transaction is recorded on the shared ledger, no participant can change or falsify that transaction. If an error is made in the record, a new transaction must be added to correct it, but both transactions will be visible.

It is important to note that, due to the nature of Blockchain, it is not possible to modify or correct transactions made on the Efy Finance platform or delete personal data required by the blockchain for such transactions.

When you make a transaction with cryptoassets, certain personal information will be recorded in the respective blockchain, including the source and destination wallet address, the amount of the transaction, and the date and time of the transaction. Once the transaction is confirmed, this information will not be under our control and we will not be able to help you exercise your rights over it. The blocks are linked chronologically and the data recorded in them is practically unalterable or removable.

This particularity of Blockchain may affect your ability to exercise certain rights as a data owner, such as the right to deletion or rectification. Although there are smart contracts that can block certain personal information from third parties, the data will still be present and cannot be deleted.

In short, if you want to ensure that your rights are not affected in any way, avoid transacting on Blockchain, as some rights may not be fully available or may not be fully exercised. In general, blockchains are open to the public and any personal data published on them will be public knowledge.

  1. What are your rights regarding my personal data?
  • You have the right to ask us if we are processing your personal data. You can exercise your right to access your personal data at any time, with reasonable frequency. Once consulted, you can ask us to rectify or delete any (inaccurate) data or to restrict or terminate the processing of your personal data. However, we reserve the right to refuse such a request to limit or cease the processing of your personal data if we have a legitimate interest in continuing the processing of your personal data, in particular if we need the information in (possible) legal proceedings.
  • You have the right to ask us to transfer (some of) your personal data to you or another party.
  • If the processing of your personal data is based on your consent, you can revoke it at any time. To exercise this right and the rights mentioned above, please contact us using the contact information provided in this Privacy Policy.
