Cookie Policy
Last updated: January 15, 2026
This Cookie Policy explains what cookies are, how Arqelium S.A. uses them on the website arqelium.com, and how you can manage your preferences. When browsing our Site, we use Google Consent Mode v2 to manage your consent transparently and in compliance with current regulations.
1. What are cookies?
Cookies are small text files that are stored on your device (computer, tablet, or mobile phone) when you visit a website. They allow the site to remember your actions and preferences over a period of time, so you don't have to reconfigure them every time you return.
2. Types of cookies we use
We classify cookies into the following categories: • Necessary cookies: Essential for the operation of the Site. They include session cookies, language preferences, and storage of your consent decision. They cannot be disabled. • Analytics cookies: Allow us to measure and analyze how users interact with the Site. We use Google Analytics 4 (GA4) to collect aggregated information about browsing patterns. These cookies are only activated with your consent. • Marketing cookies: Used to track visitors across websites in order to display relevant advertising. We use Google Ads (identifier: AW-18064110603) to manage advertising campaigns. These cookies are only activated with your consent.
3. Google Consent Mode v2
We implement Google Consent Mode v2, a system that allows granular consent management. This system: • Sets the default consent state to "denied" for analytics and marketing cookies. • Updates the consent state only after your explicit interaction with the cookie banner. • Allows Google services to operate in a privacy-respectful manner even when consent has not been granted (through aggregated and anonymized data modeling). • Stores your consent preference in your browser's local storage.
4. Managing preferences
You can manage your cookie preferences at any time through our consent banner, which appears when you first visit the Site. Available options are: • Accept all: Activates all cookie categories (necessary, analytics, and marketing). • Reject all: Only keeps necessary cookies active. • Manage preferences: Allows you to activate or deactivate each category individually. If you delete your browser cookies or local storage, the banner will reappear so you can set your preferences again.
5. Third-party cookies
Our Site uses Google services that may set third-party cookies: • Google Analytics 4 (GA4): For web traffic analysis. • Google Ads: For advertising campaign management and conversion measurement. These services are subject to Google's privacy policies. We recommend consulting https://policies.google.com/privacy for more information.
6. Cookie duration
• Session cookies: Deleted when you close the browser. • Persistent cookies: Remain on your device for a set period. Google analytics cookies are retained for up to 14 months. • Consent preferences: Stored in localStorage and persist until you manually delete them.
7. How to delete cookies
In addition to using our preferences panel, you can delete cookies directly from your browser settings. Each browser has a different process; consult your browser's documentation for more information. Please note that deleting all cookies may affect the functionality of the Site and will cause the consent banner to reappear.
8. Updates to this policy
We reserve the right to update this Cookie Policy to reflect changes in the cookies we use or for legal reasons. Any changes will be published on this page. For cookie-related inquiries, contact us at: privacidad@arqelium.com.
