Cookie policy
This page explains what cookies are, how we use them on crestelio.com and how our panel integrates with Google Consent Mode v2, the tool that lets us respect your preferences before activating measurement or advertising tools.
2. Categories we use
We use four categories: necessary (always on), functional (language and region), analytics (aggregate statistics) and advertising (Google Ads and similar partners). The preferences panel lets you switch the last three on or off.
3. Google Consent Mode v2
We implement Google Consent Mode v2 with denial by default: until you accept a category, Google Ads, GA4 and related tools do not store measurement cookies or personalise ads. When you change your preferences we send a consent update (ad_storage, ad_user_data, ad_personalization, analytics_storage) and a cookie_consent_update event to the dataLayer.
4. Managing your preferences
You can accept, reject or customise cookies from the banner that appears on your first visit. If you change your mind later, click ‘Manage cookies’ in the site footer to reopen the panel.
5. Consent retention
We store your choice in your browser’s local storage for 12 months. If you clear your browser data, the banner will reappear and we will ask for consent again.
6. Third-party cookies
When you enable the advertising category, Google may read and write cookies on its own domains to measure conversions and optimise campaigns. You can find the details in Google’s official policies.
7. Contact
If you have questions about how we handle cookies, write to privacidad@crestelio.com. We reply in Spanish and English.
