By using the MERCANZA, S.L.U. website and any of the services incorporated to it, you accept the following Privacy Policy.

1. Data collection and consent
MERCANZA, S.L.U. is RESPONSIBLE for the processing of the USER’s personal data and informs you that this data will be processed in accordance with the provisions of Regulation (EU) 2016/679, of 27 April (GDPR), and Organic Law 3/2018, of 5 December (LOPDGDD).

The purpose of the processing of your data is to maintain a business relationship or maintain a professional relationship (for the legitimate interest of the controller, art. 6.1.f GDPR) and sending communications about products or services (with the consent of the data subject, art. 6.1.a GDPR).

2. Purposes of processing
The data we request are appropriate, specific and necessary for the purpose for which they are collected, and will not be used for any purpose other than that for which they have been provided. Under no circumstances is the user obliged to provide MERCANZA, S.L.U. with these data, however it should be noted that failure to do so will mean that MERCANZA, S.L.U. will not be able to provide the services in the manner normally foreseen.

MERCANZA, S.L.U. is not responsible for the treatment of personal data from the web pages that the user can access through the different links contained in our web page.

Unless expressly indicated, it will be considered necessary to fill in all the fields of each form. The data provided by the user must be true, accurate, complete and up to date.

The user will be the only responsible for any damage, direct or indirect, caused to MERCANZA, S.L.U. or to any third party, by filling in the forms with false, inaccurate, incomplete or non updated data, or with data from third parties.

Our website obtains the user’s personal data by means of the reception of forms, and by means of e-mail, for the following purposes:

  • Subscription to online newsletters, physical publications, web pages and commercial and promotional communications related to MERCANZA, S.L.U. services.
  • Management of MERCANZA, S.L.U. for information or registration as a collaborating company and for the management and registration as a user of other MERCANZA, S.L.U. products.
  • Commercial: When the interested party sends the personal data and e-mail address to MERCANZA, S.L.U. he/she is expressly authorising its use for the purposes of periodical communications, including implicitly those carried out by e-mail. By registering for certain services, you expressly consent to receive commercial or promotional communications from MERCANZA, S.L.U.. MERCANZA, S.L.U. will also provide users with mechanisms so that, simply and free of charge, they can withdraw the consent given for the purpose of sending electronic communications, in full compliance with the European and national regulations on the aforementioned matter.

MERCANZA, S.L.U. reserves the right to decide whether or not to include the personal data of these people in its files.

3. The right (ARCO) of access, rectification, cancellation and opposition; the right to be forgotten, the right to portability of personal data and the right to limit the processing of the user’s personal data.
The user may exercise his/her right to access his/her personal information compiled in the MERCANZA, S.L.U. files and may rectify it if incorrect, cancel it or oppose its processing in accordance with the terms established by Law by expressing such wishes in writing to MERCANZA, S.L.U. via electronic mail to rgdp@mercanza.es or by post to MERCANZA, S.L.U., MARGARITA SALAS, 4 – PARQUE TECNOLÓGICO DE LEGANÉS – 28919 LEGANÉS (MADRID), always enclosing a photocopy of your ID card, or a document accrediting the entity you represent.

In addition, the introduction of the GDPR incorporates the right to be forgotten, the right to portability of personal data and the right to limitation of processing.

The right to be forgotten means preventing, by order of the data subject, the dissemination of personal information on the internet when its publication does not meet the requirements of adequacy and relevance provided for in the regulations. This includes the right to limit the universal and indiscriminate dissemination of personal data in general search engines when the information is obsolete or no longer relevant or of public interest, even if the original publication is legitimate.

The right to data portability entitles the data subject to obtain a copy of his or her personal data in a structured and commonly used electronic format and to transfer his or her data from one electronic processing system to another.

The right to restriction of processing consists of the data subject’s right to request and obtain from the controller or data controller a restriction of the processing of his or her personal data where one of the following conditions is met:

  • The data subject contests the accuracy of the personal data, during a period of time that allows the data controller to verify the accuracy of the data.
  • The processing is unlawful and the data subject objects to the erasure of the personal data and requests instead the restriction of their use.
  • The controller no longer needs the personal data for the purposes of the processing, but the data subject needs them for the establishment, exercise or defence of claims.
  • The data subject has objected to the processing

In order to keep the personal data up to date, it is important to inform the data subject whenever there is any modification; otherwise, MERCANZA, S.L.U. will not be liable for the veracity of the data.

If the user does not expressly cancel their personal data from the MERCANZA, S.L.U. files, it is understood that the user is still interested in them remaining incorporated as long as they are suitable for the purpose for which they were obtained, and for as long as MERCANZA, S.L.U. considers it appropriate.

4. Security of personal data
That in accordance with the provisions of the current regulations on personal data protection, the RESPONSIBLE is complying with all the provisions of the GDPR and LOPDGDD regulations for the processing of the personal data for which it is responsible, and manifestly with the principles described in article 5 of the GDPR, whereby they are processed lawfully, fairly and transparently in relation to the data subject and are adequate, relevant and limited to what is necessary in relation to the purposes for which they are processed.

The CONTROLLER guarantees that it has implemented appropriate technical and organisational policies to apply the security measures established by the GDPR and the LOPDGDD in order to protect the rights and freedoms of USERS and has communicated the appropriate information to them so that they can exercise them.

Our website obtains the user’s personal data by means of e-mail and contact forms, for the following purposes:

  • MERCANZA management for information or registration as a collaborating company and for the management and registration as a user of other MERCANZA services.
