EU compliance apps for Shopify (2026): what each rule needs and the apps that cover it

1. Cookie consent (GDPR and ePrivacy)

Since 2011 (ePrivacy) and 2018 (GDPR). Source: Directive 2002/58/EC, Article 5(3), and the GDPR

What the rule asks

• You may set non-essential cookies and trackers, such as analytics and ad pixels, only after the visitor consents. Cookies the shop needs to work, like the cart, are exempt.
• Consent has to meet the GDPR standard: freely given, specific, informed and unambiguous, and as easy to withdraw as to give. Each EU country enforces the cookie rule through its own law, so details such as a reject button on the first screen differ.
• Google Consent Mode v2 is not EU law. It is Google’s own requirement since March 2024 for ad measurement and remarketing in the EEA.
• Shopify has a free built-in cookie banner, set per region under Settings > Customer privacy, which Shopify says passes consent to Google Consent Mode v2. Apps add cookie scanning, automatic blocking, consent logs and more design control.

The apps

Where Complimus fits: Complimus does not cover cookie consent. Use Shopify’s built-in banner or one of the apps above.

2. Omnibus: the lowest price before a sale

Since 28 May 2022. Source: Article 6a of Directive 98/6/EC, added by Directive (EU) 2019/2161

What the rule asks

• Every announced price reduction must show the prior price: the lowest price you charged in a period of at least 30 days before the reduction.
• EU countries may set their own rules for perishable goods, products on sale for less than 30 days, and progressive discounts. Poland, for example, expects the prior price to update with every price change during a sale.
• Shopify’s compare-at price is any number you type. It is not a record of the prices you actually charged, so an app that keeps a daily price history is the practical way to show the right figure.

The apps

Where Complimus fits: Our core module, and the Omnibus app with the most reviews on this list. To be fair about it: Omnibus Owl and Netkodo cost less on paid plans, and like every tracker, our own price record builds up over the first 30 days after you install.

3. GPSR product safety information

Since 13 December 2024. Source: Regulation (EU) 2023/988, Article 19

What the rule asks

• Every online offer of a consumer product to people in the EU must show the manufacturer’s name, postal and electronic address; the EU responsible person if the manufacturer is outside the EU; information that identifies the product, including a picture and its type; and any warnings or safety information in a language shoppers easily understand.
• It applies to sellers outside the EU too, when they target EU shoppers.
• An app displays the information. It does not make anyone your EU responsible person: if your suppliers are outside the EU, you need an importer, an authorised representative or a service that takes on that role.

The apps

Where Complimus fits: Free and unlimited on every plan. What it does not do yet: product-specific warnings and batch numbers, which GCM and Omnibus Owl list. Until then, add warnings to the product description.

4. The EU legal guarantee notice and the GARAN label

From 27 September 2026. Source: Directive (EU) 2024/825 and Implementing Regulation (EU) 2025/1960

What the rule asks

• Stores must remind shoppers, prominently and with the official harmonised notice, that the legal guarantee of conformity exists and lasts at least two years.
• Where the producer offers a free commercial guarantee of durability for more than two years on the whole product, you show it with the harmonised label, titled GARAN.
• Implementing Regulation (EU) 2025/1960 sets the design: both carry a QR code and must be in colour online. Each EU country writes the rule into its own law, so check the start date for the countries you sell to.

The apps

Where Complimus fits: Free and unlimited on every plan: the notice in the shopper’s language, the GARAN label with length, brand and model per product, and exclusions by tag, type or country. Several dedicated apps are also free or $4.99, so the reason to choose ours is having it in the same app as the other three rules, not price.

5. The EU withdrawal button

Since 19 June 2026. Source: Article 11a of the Consumer Rights Directive, added by Directive (EU) 2023/2673

What the rule asks

• Online stores must offer a withdrawal function labelled “withdraw from contract here” or an unambiguous equivalent, prominently displayed and available throughout the withdrawal period.
• The shopper fills in their name, the order and the email for the confirmation, and submits with a button labelled “confirm withdrawal” or an unambiguous equivalent.
• You then send an acknowledgement of receipt on a durable medium such as email, with its content and the date and time it was received, without undue delay. The 14-day withdrawal period itself does not change.

The apps

Where Complimus fits: Free and unlimited on every plan: the button and form inline or as a popup, guest access without login, an immediate email from your sender name, and a request list with each refund deadline. You still refund in Shopify. The dedicated apps above have far more reviews, and some add returns sync and evidence packs.

Our full guide: What Article 11a requires, step by step.

6. Accessibility: the European Accessibility Act

Since 28 June 2025. Source: Directive (EU) 2019/882

What the rule asks

• E-commerce services offered to EU consumers must be accessible: perceivable, operable, understandable and robust. You also publish how your store meets the requirements, for example in your terms.
• Microenterprises are exempt: fewer than 10 people and an annual turnover or balance sheet total of EUR 2 million or less.
• Two kinds of app exist. A widget (overlay) adds a toolbar on top of your theme; it does not by itself change the theme code the rules apply to. Code-fix apps change the theme itself and cost more. Treat a widget as a help, not as compliance on its own.

The apps

Where Complimus fits: Complimus does not cover accessibility.
