Cookie & Local Storage Policy

1. What are Cookies and Similar Technologies?

A cookie is a small text file downloaded to a user's browser when accessing certain web pages. Its standard role is to enable the web server to remember technical state information regarding the session (such as language preferences, session identifiers, or layout configurations) to ensure proper navigation and, where authorized, generate aggregated analytics.

Alongside traditional cookies, equivalent client-side storage technologies exist (such as LocalStorage, SessionStorage, or technical tracking beacons), which are governed by the same legal requirements set forth in Article 22.2 of Spanish Law 34/2002 (LSSI-CE) and the guidelines issued by the Spanish Data Protection Agency (AEPD).

2. Current Website Audit and Operational Status

In accordance with the principles of technical truth and transparency, MASEG has thoroughly audited the technical technologies deployed on the current static version of this website (built on Astro SSG architecture):

Conclusion: This website does not install advertising or behavioral profiling cookies. Google Analytics 4 statistical cookies remain disabled by default until the user explicitly grants opt-in consent.

4. Measurement & Consent System (Google Analytics 4)

In accordance with technical sprint S10 (SEO & Consent-Aware Analytics), MASEG has integrated Google Analytics 4 (Measurement ID: G-KFT7V362WX) adhering strictly to AEPD and GDPR standards:

• Strict Prior Technical Blocking: The gtag.js script and analytics cookies are never loaded or executed in the user's browser before the user actively clicks "Accept analytics" or enables the category in the preference panel.
• Google Consent Mode v2: The default baseline state initializes with strict denial signals (analytics_storage: 'denied', ad_storage: 'denied', ad_user_data: 'denied', ad_personalization: 'denied').
• 100% Reversible Consent: Users can revoke consent or adjust preferences at any time via the permanent "Cookie settings" trigger located in the website footer. Revoking consent immediately halts any further analytics dispatches.
• Zero PII & Conversion Verification: MASEG never transmits names, emails, phone numbers, inquiry message contents, or internal lead IDs to Google Analytics. Inquiries are measured as conversion events only after the backend confirms secure receipt via HTTP 200.
• No Dark Patterns: "Accept" and "Reject" actions feature equal visual prominence, size, and styling hierarchy in the consent banner.
