gum.criteo.com: How Criteo Tracks Your Shopping Habits

Criteo’s tracker, gum.criteo.com, lurks on countless websites, monitoring your every move to serve hyper-targeted ads. This invasive tool builds a profile of your online behavior, stripping away your anonymity. Here’s what it does and how to shield yourself.

What Is gum.criteo.com?

Criteo operates gum.criteo.com as part of its commerce media platform, tracking users across the web to tailor advertisements. It collects data on your browsing and shopping patterns, feeding this into a system that auctions your attention to the highest bidder in real time. As Privacy Auditors, we see this as a direct threat to your digital privacy.

Data It Collects

When you’re on a site with Criteo’s tracker, it grabs:

• IP Address: Pinpoints your location, often tied to your home or office.
• Browsing History: Logs every URL, especially e-commerce or product pages.
• Ad Interactions: Records clicks on ads, with exact timestamps and ad IDs.
• Device ID: Captures unique identifiers like GAID or IDFA for cross-device tracking.
• Cookie IDs: Sets cookies (e.g., ‘_criteo’) to stalk you across websites.
• User Behavior: Tracks time on page, items viewed, or cart additions.
• Browser Type: Identifies Chrome or Safari, including version details.
• Operating System: Logs Windows 11 or iOS 16 with build specifics.
• Referrer URL: Notes where you came from, like a search engine.
• Timestamps: Marks every action down to the second.

This data creates a precise map of your online life, ripe for exploitation.

Who Gets Your Data?

Criteo shares your information with:

• Advertisers: Companies paying to target you with personalized ads.
• Adtech Partners: Entities in real-time bidding systems for ad slots.
• Third-Party Data Brokers: Firms enhancing user profiles with your data.
• Cloud Providers: Services like AWS storing and processing your info.
• Government Agencies: If legally required, per Criteo’s compliance terms.
