BannerWarden is a consent management platform built for ecommerce. It adds a compliant cookie banner to your store, holds ad pixels and tracking apps until shoppers opt in, and keeps checkout cookies untouched so carts and sessions always work. It covers GDPR for EU shoppers and CCPA opt-outs for California, with dedicated apps for Shopify, WooCommerce, and BigCommerce.

Cart, session, and payment cookies are classified as strictly necessary and never blocked, so shoppers can always buy. The banner only holds the marketing and analytics layer: ad pixels, affiliate trackers, personalization tools, and review widgets that set non-essential cookies. Compliance never touches the checkout.
Meta, TikTok, Google, and Pinterest pixels stay silent until consent, which is what GDPR requires. For declined traffic, BannerWarden passes consent state through each platform's consent framework, including Google Consent Mode v2 and Meta's consent parameters, so platforms can model conversions instead of reporting nothing.
Yes. The Shopify app integrates with Shopify's customer privacy API, so consent choices also flow to apps that read Shopify's native consent signals. You get one banner controlling both the script-level blocking and the platform-level consent state, instead of two systems disagreeing.

The banner itself rarely does; it appears once and dismisses fast. What hurts stores is a badly implemented banner that breaks cart sessions or blocks the wrong scripts. BannerWarden never touches necessary cookies, and the banner is tuned for mobile, where most store traffic is. Consent rates are also design-sensitive, which is why wording and layout are fully editable.
If you have EU or UK visitors and run any analytics or ad pixels, yes: GDPR requires opt-in consent before those fire. California's CCPA/CPRA requires an opt-out mechanism instead. Since stores ship internationally by default, a region-aware banner that shows the right behavior per shopper location is the practical answer.
Global Privacy Control is a browser signal that tells sites the visitor opts out of data sale or sharing, and California law requires honoring it. BannerWarden detects GPC automatically and applies the opt-out without showing a banner interaction, then records the choice in the consent log.
Yes. Review apps, upsell widgets, chat tools, and affiliate trackers are detected by the store scanner and can be assigned to categories. Their scripts are held until the shopper consents to that category. The scanner re-runs weekly because stores add apps constantly.
Declined shoppers stop appearing in pixel-based reporting, which is legally required. BannerWarden turns on the modeling features each platform offers, so Google and Meta estimate the missing conversions from consented behavior. Most stores recover a useful share of reporting accuracy without touching compliance.
Start with the free consent audit: we scan your store and show you every tracker your apps and pixels set, and which ones fire before a shopper opts in. Plans are sized by stores and traffic after that. The audit carries no charge and no card.
