4. Cookies
Three categories detailed in the cookie policy: strictly necessary, analytics (opt-in), advertising (opt-in).
5. Google AdSense, DoubleClick and personalised advertising
With consent, Google may set and read __gads, __gpi, IDE, NID, DSID, and test_cookie; process IP, user-agent and approximate location; build interest-based advertising profiles; and share data with TCF v2.3 vendors you authorise. Google's processing: policies.google.com/privacy and policies.google.com/technologies/ads.

We use a TCF v2.3-compliant CMP. No non-essential cookie is set, and no third-party advertising script is loaded, until you grant or refuse consent on a per-purpose, per-vendor basis. Modify via the “Cookie preferences” footer link.
7. International transfers
Some third parties (notably Google) transfer personal data outside El Salvador. Such transfers rely on the EU–U.S. Data Privacy Framework, Standard Contractual Clauses, and the local cross-border transfer requirements where applicable.
8. Your rights
Under Salvadoran law, GDPR, and CCPA/CPRA you may access, correct, request erasure, restrict processing, port your data, and withdraw consent. Lodge complaints with the relevant Salvadoran authority, the Information Commissioner (UK), your supervisory authority (EU member states), or the California Privacy Protection Agency.
California residents may opt out of “sale”/“sharing.” We honour the GPC signal.
