SECTION 2: Marketing cookies disclosures

When you consent to marketing cookies, we use advertising tools to measure performance and, where available, to show relevant ads to people who have visited our website. The statements below describe how advertising cookies and tracking technologies are used.

Third-party vendors, including Google, use cookies to serve ads based on a user's previous visits to this website and other sites on the internet.

We may work with advertising partners such as Google and Meta to deliver advertisements tailored to your interests across various websites and platforms.

We may use remarketing services to advertise to previous visitors of our website. After visiting our site, you may see our ads on other websites, apps, or platforms you visit.

Advertisements may appear across Google services including YouTube, Gmail, and the Google Display Network.

We use the following tracking technologies on this website:

  • Cookies (first-party and third-party)
  • Tracking pixels (Google Ads tag / gtag.js, Meta Pixel)
  • Device identifiers (browser fingerprint, IP address)
  • Conversion event tags

We use conversion tracking to understand which advertisements lead to actions on our website such as form submissions, calls, or purchases. This allows us to measure campaign effectiveness and allocate budget appropriately. Conversion data may be shared with Google Ads and Meta.

Advertising and analytics technologies active on this site:

  • Google Ads (gtag.js / Google Tag Manager)
  • Google Analytics 4
  • Google Remarketing Tag

SECTION 4: Data Sharing with Advertising Partners

We share certain data with advertising partners for campaign delivery and measurement. Recipients and the data categories shared include:

  • Meta Platforms, Inc.: pixel events, conversion data, custom audiences. Governed by Meta's Data Policy: https://www.facebook.com/privacy/policy

We do not sell personal data. All transfers to Google and Meta operate under Standard Contractual Clauses where applicable. Data is processed for ad targeting and campaign measurement only, not resold to unaffiliated third parties.

Google and Meta may use this data across their own platforms in accordance with their respective policies. We encourage users to review those policies directly.

SECTION 5: Lead Forms and Contact Requests

When you submit a contact form, request a quote, or register interest in our services, we collect the information you provide. This typically includes: full name, email address, phone number, and your message.

Legal basis: consent (GDPR Art. 6.1.a) and, where a service relationship exists, performance of a contract (GDPR Art. 6.1.b).

SECTION 6: Google Services and Advertising

This website uses the following Google services:

  • Google Remarketing: allows us to show ads to previous visitors across Google's network. Remarketing lists are not created from sensitive data categories (health, finance, religion, sexual orientation).
  • Google Tag Manager: deploys tracking tags on our behalf. No personal data is collected by GTM itself; it acts as a container for the tags listed above.

Google's advertising products are governed by: https://policies.google.com/technologies/ads

This website uses the Meta Pixel to measure the effectiveness of our advertising on Facebook and Instagram. The pixel may record:

We do not use the Meta Pixel to collect sensitive personal data, nor to target users based on health status, financial situation, religion, political views, sexual orientation, or any other special-category attribute prohibited under Meta's advertising policies.

Meta acts as an independent data controller for data collected via its Pixel and processed within its own platform. Refer to Meta's Data Policy: https://www.facebook.com/privacy/policy
