Cookies policy


This Cookies Policy is an integral part of the Conditions of Use and Contracting and the Privacy Policy of the online platform owned by Mercadona (hereinafter, the “Platform”). Accessing and browsing the Platform, or using its services, implies that you accept the terms and conditions of the Conditions of Use and Contracting and the Privacy Policy.

In order to facilitate browsing of the platform, MERCADONA S.A., as its owner (hereinafter, the “Owner”), with registered address at Calle Valencia no. 5, Tavernes Blanques (Valencia), and with Spanish Tax ID A-46.103.834, hereby notifies you that it uses Cookies and other similar files that function in a similar way (hereinafter, “Cookies”).

In any case, we hereby inform you that the Owner is responsible for the Cookies and for the processing of the data obtained through own and third-party Cookies, deciding on the purpose, content and use of the processing of the information collected.


What is a Cookie?

Cookies are files containing small amounts of information that are downloaded onto the user's device when they visit a webpage, and which are exclusively associated with an anonymous user and their computer, and do not provide information that enables access to the user’s personal data.

Cookies are essential for the Internet to function, and their main purpose is to recognise the user every time they access the Platform in order to improve quality, offer better use of the Platform by personalising the services offered there, and provide the user with information of interest or which may be of interest based on their use of the services.


Use of Cookies by the Owner

We inform you that the web page has different subdomains (e.g., online store, customer service, etc.). The cookies required or requested in the different subdomains may be different or vary from those on the main page. For that reason, we provide you with information about cookies and ask for your consent (when required under current law) when you click on any of the subdomains that use cookies. Furthermore, you can change your cookies settings and accept/reject new functionalities at any time in the panels provided in each of the subdomains mentioned here, as well as obtain more information through the cookies policies on our sites or by contacting us.

Users expressly authorise the use of this information for the purpose indicated, without detriment to their right to reject, disable or configure the use of Cookies. If Cookies are disabled or rejected, browsing the Platform may not be optimised and some of the features on the Platform may not function correctly.

Specifically, the Owner is using the Cookies for the purposes described below. If the Owner were to use other Cookies in the future for the purposes of providing more and better services, the user will be informed.

The installation of these Cookies on the user’s device always happens after receiving their consent and/or after the Cookies have been configured.

This Policy generally informs you of all the Cookies used on the Platform, however, for the user’s knowledge, it is important to highlight that Cookies that are non-essential to the functioning of the Platform will be activated by default and cannot be disabled or rejected by users (always in compliance with regulations in force).


Types of Cookies used and their purposes

This website uses its own and third-party Cookies. They are grouped as follows, based on who manages the data obtained via the Cookies:

  • Own: They are sent to the editor that provides the service requested by the user.
  • Third-party: They are not managed by the editor, but rather by a third party who manages the data obtained via the Cookies.

Based on how long they are stored:

  • Session: They are stored while you access and browse the website, and are deleted when you leave the website.
  • Permanent: They are stored on the terminal and can be accessed and processed for a time defined by the party responsible for the Cookie..

What Cookies do we use on our website?

We use our own and third-party Cookies on our website.

Own Cookies:

These Cookies are considered essential for browsing the website by making it possible for the user to use its features or tools, like, for instance, logging in, accessing restricted sections, and ensuring safe browsing. Without these Cookies, these functions would be disabled. That is why these Cookies are activated by default and cannot be configured by users.

In this sense, the Owner uses these own Cookies for the following purposes:

  • Identifying the user’s session to keep it active during browsing.
  • Identifying the user's session to prevent possible attacks.
  • Identifying the user’s Cookies configuration.
  • Configuring the safety of the website’s firewall.
  • Verifying the connection with servers (for instance, with Oracle). In these cases, these Cookies can be third-party, but they always have the purpose described.

Likewise, in some sections of the Platform, the user’s geolocation is needed. These technologies will only be used after first warning the user (with a pop-up window, for instance). This geolocation will only be used to provide the service requested (to locate nearby stores, for instance) and never for any other purpose.

Unnecessary Analytical Cookies

These Cookies are used to analyse the user’s browsing of the website and to do an accounting of them. Some of these Cookies identify the user, while others only use aggregate data.

The Owner, through the Platform, uses Google Analytics, (never permanent Cookies), a service provided by Google, Inc., a company headquartered at 1600 Amphitheatre Parkway, Mountain View (California), CA 94043, United States (hereinafter, "Google").

Google Analytics uses Cookies to analyse how users use the Platform. The information generated by the Cookie (including the user’s IP address) will be directly transmitted and stored by Google on its servers in the United States. Google will use this information on behalf of the Owner to track users’ use of the Platform, gathering activity reports and providing other services related to the Platform’s activity and Internet use. Google can transmit this information to third parties when required by law, or when the third parties process the information on Google’s behalf, and even to the Owner of the Platform. Google will not associate your IP address with any other data they have.

If you would like further information, you can go to the Google URL

With these Cookies we can:

  • Distinguish users by assigning them an anonymous identifier.
  • Personalise ads based on your interests.
  • Remember how the user accesses the platform.

User configuration to avoid Cookies

Likewise, the Owner gives users of the Platform information about configuring their Internet browser/browsers to maintain their privacy and security in relation to Cookies. To do so, it provides this information with links to the official support sites of the main browsers so that every user can decide whether or not to accept the use of Cookies.

Cookies can therefore be blocked using the browser’s configuration tools, or each user can configure their browser to notify them when a server wants to save a Cookie onto their device:


Can the Cookie Policy change?

This Cookies Policy may be changed based on legal or regulatory requirements or in order to adapt the policy to instructions dictated by the Spanish Data Protection Agency, so users are advised to visit it regularly. When major changes are made to this Cookies Policy, users will be notified either through this website or via email.
