What are cookies?

A cookie is a small text file saved on your browser when you visit a website. It allows the site to recognize your device, remember your preferences, and ensure core features function properly.

Strictly necessary cookies

These cookies are required for you to browse the site, log in securely, and keep your preferred language. Without them, DX Builder cannot operate properly, so they do not require your prior consent.

Marketing and advertising cookies

We use cookies from Google Ads and Meta to measure the performance of our marketing campaigns and display relevant ads. These cookies are only set after you click "Accept" on our cookie banner. If you decline or withdraw your consent, they are immediately removed from your browser.

Privacy-friendly audience measurement

We run strictly internal audience measurement on our own servers (page views, approximate country, visit source). Your IP address is immediately converted into an irreversible anonymous hash, with no cross-site tracking, no data enrichment, and no sharing with third parties. In accordance with CNIL guidelines, this technical measurement is exempt from prior consent.

How to manage your choices

You can change or withdraw your consent at any time by clicking the "Manage cookies" link in our website footer. You can also configure your browser settings to block or delete cookies whenever you wish.

Data transfers outside the EU

Certain marketing providers (Google, Meta) may process data on servers located outside the European Union. These transfers are governed by standard contractual clauses approved by the European Commission and GDPR-compliant safeguards.

Your rights and supervisory authority

Under the GDPR, you have the right to access, rectify, erase, restrict, port, and object to the processing of your personal data. You also have the right to lodge a complaint with the French supervisory authority (CNIL — Commission Nationale de l'Informatique et des Libertés) at cnil.fr.
