A cookie is a small file that the website downloads onto the User's device when accessing certain pages. It allows the site to remember information about the visit — preferences, language, session — and to obtain aggregated usage metrics.
This policy explains which cookies we use on www.descarboniza.es, for what purpose, and how you can configure or reject them, in compliance with Law 34/2002 (LSSI-CE), Regulation (EU) 2016/679 (GDPR) and Organic Law 3/2018 (LOPDGDD), as well as the guidelines of the Spanish Data Protection Agency.
Based on their purpose, the cookies used on this Website can be classified as follows:
Based on ownership, cookies may be first-party (managed by Descarboniza) or third-party (managed by providers that render services to Descarboniza). Based on duration, they may be session cookies (deleted when the browser is closed) or persistent cookies (remaining for the period indicated in each case).
The main services and cookies in use are detailed below:
| Service / cookie | Type | Purpose | Duration |
|---|---|---|---|
| Cookie consent (first-party) | Technical | Remember the User's preferences regarding cookie use. | Persistent (12 months) |
| Clerk (authentication) | Third-party technical | Keep the registered User's session active. | Session / persistent |
| Google Tag Manager (_gtm) | Third-party technical | Load analytics and measurement tags in a centralised manner. | Session |
| Google Analytics (_ga, _ga_*) | Third-party analytics | Anonymous usage statistics, pages visited, devices. | Persistent (up to 24 months) |
| Vercel Analytics | Measurement (cookie-free) | Aggregated, anonymised performance and traffic metrics. It does not set cookies or use persistent identifiers; as it is anonymous audience measurement, it does not require prior consent. | Does not use cookies |
This table may be updated as services are added or removed. The version in force is always the one published on this page.
Technical cookies are used on the basis of the controller's legitimate interest and are necessary to provide the service requested by the User. Analytics cookies are only installed once the User has given express consent through the cookie banner or the settings panel.
The first time you access the Website, a banner appears allowing you to accept all cookies, reject them, or configure them individually. The User may review or change their choice at any time by reopening the settings panel (cookie icon available at the bottom of the Website) or by deleting the cookies stored in their browser.
In addition, the main browsers allow cookies to be managed through their own settings:
Disabling technical cookies may affect the proper functioning of the Website and the availability of some features.
Some technology providers (Clerk, Google, Vercel) may process data in countries outside the European Economic Area. In such cases, transfers are covered by the Standard Contractual Clauses approved by the European Commission or by other appropriate safeguards provided for under data protection law.
The processing of personal data collected through cookies is additionally governed by the Privacy Policy. For any query, write to hola@descarboniza.es.
Descarboniza may update this Cookie Policy to adapt it to regulatory, technical or provider-related changes. The version in force will always be the one published on this page.
