3. Purpose of data processing and legitimation: for what purpose, and on what legal basis, can we process your data?
Rentalia will process your data for the following purposes:
3.A) Necessary processing for the provision of the services you request from us
There are a series of data that we request from you as "obligatory", because they are necessary to provide you with the services you request from us.
As for the list of these services we offer you, they include:
As a consequence of the services described in the previous points, Rentalia will also send transactional communications regarding the operation of the services or the operation of any other contracted service (these transactional communications will be related to the management and solution of possible technical incidents, notifications in case of modification of the contracting conditions or for the management of any possible claim that you may need to make regarding the hiring of the services).
3.B) For Rentalia's legitimate interest
We will now explain the different circumstances in which we may process your data on the basis of a legitimate interest:
In accordance with the GDPR, we have carried out what is known as a "balancing test". This is an internal analysis to confirm that our legitimate interest does not harm the interests of data subjects in the protection of their personal data. As a conclusion of this test, we understand that BDMI's legitimate interest prevails due to the reciprocal interest that exists between us and the company you represent in ensuring the correct representation and interrelation with a legal entity, in order to be able to properly manage the contractual relationship with it. Furthermore, Article 19 of the LOPDGDD allows this processing.
In this context, we will also detect fraudulent advertisements based on pre-established parameters (suspicious IP, very low/high prices, location of the property, etc.). If Rentalia detects such advertisements, it will proceed to the application of the corresponding protocol to verify the identity of the advertiser and the reality of the advertisement.
For this processing we have carried out a balancing test, and we understand that we have a legitimate interest that does not affect your privacy, as we carry it out to ensure the quality of our services and a secure environment on our Website and Apps. As a consequence of this test, we understand that this processing does not prejudice your fundamental rights and freedoms, especially considering that we will only use the minimum data we need to verify your identity and prevent fraud in Rentalia's environments.
Specifically, in order to carry out this activity, Rentalia will process the data obtained from the observation of your browsing habits on the Website and Apps, as well as the monitoring and analysis of your behaviour when you browse in these environments. With this information and the information that belongs to Rentalia's internal sources (i.e., information that we obtain directly from you, without consulting any file or database, such as, for example, data that you provide when you contract any of our services), we will carry out an analysis of your interests to determine which of our products and services best fit your profile. No automated decisions that would have any legal or other significant effect on you will ever be made with regard to the aforementioned profile.
This processing involves the acceptance of cookies in terms of consent, that’s why idealista will process the personal data obtained from the use of analytical, preference and advertising cookies, provided that you have given your express consent to this effect through the cookie configuration panel. For more detailed information, you may consult our Cookies Policy.
- We will send you promotional communications about Rentalia's own products and services, which are related to the ones you have initially contracted. In order to send you these communications we will take into account the commercial information we hold about you, in accordance with the previous point. This will allow us to send you communications tailored to your consumption habits and preferences, as well as to carry out quality surveys about the services you have contracted with Rentalia, in order to receive your feedback and improve our services.In this case, we have also carried out a balancing test and, as a conclusion, we understand that our interest in carrying out this processing prevails: (i) to be able to maintain the relationship with you by contracting new products; (ii) to know your feedback regarding the services provided; and (iii) to make the appropriate improvements in relation to the suggestions you have made about the contracted services.
Therefore, we understand that we have a legitimate interest that does not affect your privacy, since only data that you yourself have provided us with, or that have been generated in the contractual relationship (excluding data obtained from external sources), will be used for this processing.
