There are also other technologies, such as browser session storage (Session storage), which allow you to store information temporarily without using a traditional cookie.
These technologies can collect identifiers and navigation data that, alone or in combination with other data, can constitute personal data.
Cookies and storage technologies can be classified according to their purpose:

Preferences or customization: they remember certain options, such as the language or the selected configuration.
Analytics: They allow us to know how the site is used and to evaluate its performance.
Advertising and campaign measurement companies: They allow us to identify the origin of visits and measure the results of marketing actions.

When the visitor submits a form, the tracking information is incorporated into their request and transmitted to the Odoo CRM used by ESGROUP. There, it can be associated with the name, email address, phone number, and other data provided in the form.
