Shopify Buy Button and Data Protection – What Belongs in Your Privacy Policy

If a website operator embeds the Shopify Buy Button on its website, when a page with the embedded Buy Button widget is loaded Shopify typically processes web server log data and – in the further order process – order and payment data of users, in order to allow products to be sold directly from a foreign website via a Shopify shop. This page shows website operators in Germany what data Shopify processes according to the provider's publicly available information and which mandatory disclosures belong in the privacy policy.

A. Purpose and Functionality of the Shopify Buy Button

The Shopify Buy Button is a JavaScript widget that can be embedded in foreign websites, allowing website operators – even without a dedicated Shopify shop as their main sales channel – to integrate products from a Shopify back-end into other websites (e.g. a WordPress site, a custom CMS, a blog). When the Buy Button is clicked, a cart and checkout overlay opens, hosted and delivered by Shopify. The actual purchase process (cart, payment, order completion) thus takes place within the Shopify infrastructure.

This page focuses on the integration function Buy Button widget. Other Shopify functions (full Shopify shop, Shopify POS, Shopify apps) are not within the scope of this article. As soon as a device loads a page with the embedded Buy Button, the user's browser fetches the widget directly from Shopify servers.

B. Mandatory Disclosures in the Privacy Policy when Using the Shopify Buy Button

The GDPR requires the privacy policy to set out tool-specific minimum content in addition to general information about the website operator, data subject rights and the supervisory authority. For the use of the Shopify Buy Button this includes in particular:

• the purposes of the processing (Art. 13 para. 1 lit. c GDPR),
• the legal bases (Art. 13 para. 1 lit. c GDPR),
• where based on legitimate interests, the specific interests pursued (Art. 13 para. 1 lit. d GDPR),
• the recipients or categories of recipients (Art. 13 para. 1 lit. e GDPR),
• whether data is transferred to an insecure third country (Art. 13 para. 1 lit. f GDPR),
• the storage duration or the criteria used to determine it (Art. 13 para. 2 lit. a GDPR),
• where data is not collected directly, additionally the categories of personal data (Art. 14 para. 1 lit. d GDPR).

It is not necessary to list the Shopify Buy Button with its own boilerplate text in the privacy policy, even though that practice is widespread. The "one boilerplate per tool" approach has become poor practice: it leads to long, redundant texts, makes the privacy policy hard to maintain and tends to run counter to the transparency requirement of Art. 12 para. 1 GDPR. A topic-oriented approach is more appropriate – describing processing across topics (third-party content, sales/payment, etc.) and naming Shopify only in an annex of recipients. This is exactly the methodology that the matterius generator follows.

C. Provider of the Shopify Buy Button

According to the publicly available information from the provider, the contracting party for German website operators is Shopify International Limited, based at 2nd Floor Victoria Buildings, 1–2 Haddington Road, Dublin 4, D04 XN32, Ireland. The corporate parent company is Shopify Inc., based at 151 O'Connor Street, Ground Floor, Ottawa, ON, K2P 2L8, Canada.

Canada is a safe third country under the European Commission's adequacy decision. Where Shopify uses group or subprocessor entities in the USA, the transfer is safeguarded according to the publicly available information via EU Standard Contractual Clauses and – with respect to US-certified subprocessors – via the EU-US Data Privacy Framework.

Shopify's privacy notice is available at https://www.shopify.com/legal/privacy. The Data Processing Addendum is provided via the Shopify Trust Center.

D. Data Processing by the Shopify Buy Button – Step by Step

E. Data Collected by the Shopify Buy Button

In connection with the Shopify Buy Button, the data processed according to the provider's publicly available information typically includes IP address, timestamp, requested URL, referrer, user-agent, device and browser information, conversion events (display of the widget, click, order completion) and – in the order process – name, address, email address, telephone number, order positions and payment data.

The data can be classified into the following standardised data categories:

• Web server log data: IP address, timestamp, URL, referrer, user-agent, status code of the server response.
• Device data: device type and operating system.
• Browser information: browser name and version.
• Coarse location data: location derived from the IP address at city or municipality level.
• Conversion events: display of the widget, click, order completion.
• User content: data entered in checkout form fields (e.g. order notes).

In the order process, typical purchase and payment data is also processed (name, address, email, order positions, payment information).

F. Purposes when Using the Shopify Buy Button

Website operators typically use the Shopify Buy Button to sell products directly from a foreign website without redirecting the user to a separate Shopify shop.

These purposes can be classified into the following standardised purpose categories:

• Provision of functionality: display of the Buy Button and checkout overlay as third-party content and provision of the payment and order function.
• Contract performance: handling of the purchase contract between website operator and user, including payment processing and shipping.
• Security and abuse prevention: detection and prevention of fraud in the order process.
• Fulfilment of retention obligations: retention of order data to comply with tax and commercial law obligations.
• Communication: order confirmation and follow-up enquiries.

G. Legal Bases when Using the Shopify Buy Button

In a first step, the Shopify Buy Button must be assigned to a tool category: it is mainly a tool from the Sales/Payment category, complemented by the Third-party content category, since the widget loads content directly from Shopify servers.

In a second step, the following legal bases typically come into consideration:

• For the embedding of the widget as third-party content: typically third-party-content consent under Art. 6 para. 1 lit. a GDPR in conjunction with § 25 para. 1 TDDDG. Where the widget serves solely to provide an explicitly requested payment and order function, reliance on the necessity exception in § 25 para. 2 TDDDG or Art. 6 para. 1 lit. b GDPR may be considered; the assessment must be made on a case-by-case basis.
• For the processing of order and payment data: contract performance under Art. 6 para. 1 lit. b GDPR.
• For the retention of tax and commercial law data: legal obligation under Art. 6 para. 1 lit. c GDPR (e.g. § 147 AO, § 257 HGB).
• For fraud prevention and security: legitimate interests in abuse prevention and security under Art. 6 para. 1 lit. f GDPR.

Which legal basis is specifically applicable depends on the configuration of the use (consent banner, widget configuration) and must be examined by the website operator on a case-by-case basis.

H. Particularities and Notes on the Shopify Buy Button

• DPA: Shopify provides a Data Processing Addendum; concluding it is generally mandatory when used by website operators in Germany.
• Third-party content: The Buy Button loads JavaScript and content from Shopify servers. Prior consent in the consent banner may be required to the extent that the widget does not serve solely to provide the explicitly requested payment function.
• Third-country transfer: Shopify International Limited is based in Ireland; the parent company Shopify Inc. is in Canada (safe third country under the adequacy decision). US subprocessors are safeguarded via EU Standard Contractual Clauses and, where applicable, the EU-US Data Privacy Framework.
• Subprocessors: A list follows from the Shopify Trust Center.
• Settings for the website operator: Recommended is a deliberate configuration of the Buy Button, coupling with the consent management system and careful documentation of the order and payment processing.
• Source note: The information is based on the provider's publicly available publications and does not replace a case-by-case assessment.

I. Frequently Asked Questions on the Shopify Buy Button and Data Protection

J. Conclusion on the Shopify Buy Button

When using the Shopify Buy Button, personal data of users is transmitted directly to Shopify. The contracting party is typically Shopify International Limited, based in Ireland; the parent company Shopify Inc. is based in Canada (safe third country). Key obligations are concluding a data processing agreement, robust integration into consent management and including Shopify in the recipients annex of the privacy policy.

It is generally not advisable for the website operator to include a dedicated boilerplate text for the Shopify Buy Button in the privacy policy. A structured, topic-oriented approach is recommended that explains tools across topical blocks (third-party content, sales/payment, etc.) and only names individual providers such as Shopify in an annex of recipients. This is exactly the methodology that the matterius generator follows.
