Consent Guard vs Consentmo GDPR Compliance

Consentmo is one of the two biggest apps in this category. It has 1,990 reviews and a 5.0 average, counted on their listing on 2026-09-05. The feature set is broad: Consent Mode v2, ADA/WCAG accessibility tools, DSAR pages, TCF v2.3 on the enterprise tier.

If you need one app to cover GDPR plus accessibility plus a dozen regional privacy frameworks, it's a fair pick.

Consent Guard fits a narrower case. You want the banner to actually disappear when you uninstall, and you want a consent app that holds no access to your customers, orders or analytics at all.

One review worth reading, and the reply under it

Project Element (Israel) left a 1★ review on January 31, 2026. They removed Consentmo after 10 minutes of use and then lost tracking. In the merchant's words:

since then my pixel tracking is completely off. and not by a few percantage but by more than 95% !!

On the cause, they wrote "it might be from leftover code or something."

Consentmo replied two days later that the app "doesn't leave any scripts or leftover code once it's uninstalled". Their explanation was different: if no consent banner is active after an app is removed, tracking can stay blocked.

I can't tell from outside that store which explanation is right, and this page doesn't pretend to. A 5.0 average across 1,990 reviews says this is the exception. It still raises a fair question for any consent app. What is left on your storefront after you remove it, and what happens to your tracking then?

What that means in Consent Guard

Consent Guard's banner ships as a Shopify theme app extension, not a ScriptTag injection. You can check it: extensions/consent-banner/shopify.extension.toml reads type = "theme". Shopify removes theme app extension blocks automatically on uninstall, so there is no separate script left running after the app is gone.

That answers the first half of the question, not the second. Consentmo's reply points at something true for every consent app, this one included: once the banner is gone, your store's own privacy settings decide what your pixels are allowed to do. Removing a banner does not, by itself, bring tracking back.

The second difference is what the app can reach. Consent Guard requests no access scopes at all. Its shopify.app.toml carries a literal scopes = "", so it cannot read your customers, orders, products or analytics even by mistake.

Consentmo's listing declares, under Data access, "Sensitive data, device and activity data" plus "Customers, products, orders, Online Store, Shopify admin". That is not a criticism. DSAR pages, consent logs and a policy generator genuinely need that access. It is the trade: their feature set requires the permissions, this one has none to give away.

There are three plans. Free at $0 covers the banner, the Customer Privacy API and a manual homepage scan, with unlimited impressions. Starter at $9.90 a month adds automatic tracker monitoring. Pro at $19.90 a month adds a deep multi-page scan and a compliance report export.

Worth being straight about one of those. Consentmo's free plan includes a cookie scan, so the Starter tier is charging for something you can get from them at $0.

Where Consentmo is still ahead

Consentmo covers real ground Consent Guard doesn't. Google-certified Consent Mode v2, so a GTM-managed GA4 setup actually respects consent rather than only Shopify's own integrations. ADA and WCAG accessibility tooling. DSAR request pages. Support for a dozen non-EU frameworks, including CCPA, LGPD, PIPEDA and APPI.

Consent Guard's banner currently calls only Shopify's own Customer Privacy API, in extensions/consent-banner/assets/consent-guard.js. It does not bridge to gtag('consent', 'update', ...). A merchant running Consent Mode v2 needs Consentmo or a similar tool for that integration today.

So if your setup is GTM plus GA4, or you need accessibility and DSAR tooling out of the box, Consentmo covers more ground right now.

Consent Guard is the better fit if your problem is simpler than that. You get a clean banner that calls Shopify's native consent API, and a tracker scanner that tells you what is actually running on your storefront.

Consent Guard is a Shopify app that shows a cookie-consent banner Shopify's pixels respect and scans your storefront for trackers, for merchants who want GDPR consent without granting store access.
