A detailed look at how Cookie Manager Tarteaucitron — Turnkey GDPR compliance for PrestaShop works, why we built it the way we did, and the thinking behind the features above.
Why a specialised GDPR module
European data protection authorities have actively been auditing cookie banners since 2022. Sanctions have hit Google (€60M), Amazon (€35M) but also European e-commerce SMEs (up to €1M fine). The most-audited non-compliances: refusal less accessible than acceptance, third-party cookies dropped before consent, lack of audit log. Cookie Manager Tarteaucitron solves these three points with a modern approach.
Tarteaucitron + modern UX
The tarteaucitron.js engine is one of the most respected open-source consent management tools in Europe (used by gouv.fr sites). It is technically irreproachable but its UX is dated. Our module keeps the tarteaucitron engine (a guarantee of reliability and technical compliance) and enriches it with a modern Axeptio-style UX: floating card, iOS toggles, smooth animations. The best of both worlds.
Google Consent Mode v2: don't lose measurement
Many merchants think GDPR compliance = losing 50% of analytics data. With Consent Mode v2 (introduced by Google in 2024), this is no longer true: even without full consent, your tags can send anonymised data that feeds modelled conversions. The module implements it automatically with default state configuration (denied recommended for EEA).
Automatic third-party service scanner
Manually configuring each service (GA4, GTM, Meta Pixel, TikTok, Hotjar, etc.) takes hours. The built-in scanner analyses your front-office in one click and automatically identifies the third-party services present. One-click activation of detected services with default configuration. For custom or exotic services, the dedicated tab allows adding unlimited services with custom JS.
Audit log for DPA inspections
Every acceptance, refusal and personalised preference is logged in database with an anonymous identifier and a hashed IP (to respect GDPR while keeping traceability). In case of DPA or data protection authority inspection, you have the historical proof of every consent with timestamp, hashed IP, detailed choice. CSV export of logs available.
Stripe: essential cookie by default
Interesting special case: Stripe drops cookies necessary for payment, which are legally considered "essential cookies" to the service — not requiring consent. The module treats them this way: active without consent request, but displayed in the "Always active" category of the preferences panel for transparency. Avoids payments failing when a customer refuses cookies.
