GDPR and CCPA exist for the same purpose: data protection. Although there are notable differences between the two, the good news is that if you make an effort to comply with GDPR, you'll more than likely comply with CCPA. CCPA seems to be a more lenient version of GDPR, but it is still important to review CCPA in its entirety to make sure you comply. What Is GDPR? The Global Data Protection Regulation (GDPR) came into effect on May 25, 2018 and effectively overhauled the way online user data is handled↗. It was put into place to protect the personal information↗ of each European Union citizen and was then adopted by many other governments. What Is CCPA? The California Consumer Privacy Act (CCPA) came into effect two years after GDPR on July 1st, 2020, stirring some real concerns within many businesses. This act, enforced by the California Attorney General, followed in the footsteps of GDPR but covered a different area. Differences Between GDPR and CCPA There are five main differences between GDPR and CCPA:
- CCPA laws apply to for-profit entities whose business meets specific characteristics, while GDPR laws apply to any company and its websites.
- GDPR covers the processing of all personal data with a couple of exceptions, while CCPA is more particular regarding the types of data protected under various circumstances.
- The definitions for data collecting, processing, and selling vary for GDPR and CCPA. It is important to cross-reference these to make sure you comply.
- GDPR requirements are a lot more detailed and stringent when it comes to information that must be provided to data subjects.
- When it comes to penalties, GDPR reprimands businesses pre-emptively↗, while CCPA is reactionary. However, all the penalties are harsh and should not be taken lightly.
How GDPR and CCPA Affect Your Shopify Store
Your eCommerce business likely collects customer data at every touchpoint—email signup forms, checkout pages, abandoned cart emails, and retargeting pixels. GDPR and CCPA dictate how you can collect, store, and use that data differently depending on where your customers live.
If you sell to Europeans, GDPR applies regardless of where your Shopify store is hosted. You need affirmative consent before installing tracking pixels (like Meta Pixel or Google Analytics) and before sending marketing emails. "Affirmative" means customers must actively opt in—pre-checked boxes don't count.
If you serve California residents (even if your business isn't based there), CCPA applies. Unlike GDPR, CCPA gives consumers the right to opt out of data sales, rather than requiring them to opt in first. However, this distinction matters less in practice because many eCommerce brands choose to implement GDPR-level consent anyway—it's simpler to have one strict standard than to manage two different consent flows.
The practical takeaway: your cookie banner and consent settings need to reflect where your customers are. A Shopify store serving only US customers outside California has different requirements than one shipping globally. A DTC brand using Klaviyo for email marketing needs to ensure list-building complies with both regulations, which typically means explicit consent for every region.
Understanding "Personal Data" Under Each Regulation
Both GDPR and CCPA protect "personal data," but they define it differently—and those differences create real compliance gaps for your store.
GDPR defines personal data broadly as any information relating to an identified or identifiable person. This includes obvious data like names and email addresses, but also IP addresses, cookie IDs, and even hashed email lists. If data can reasonably be linked back to a person, GDPR covers it.
CCPA has a narrower scope. It protects personal information that identifies, relates to, or could be linked with a particular consumer or household. The CCPA does not protect B2B data, publicly available information, or certain deidentified data. This means some customer interactions your Shopify store tracks might be protected under GDPR but not CCPA.
For eCommerce, this matters when you're building audience segments. If you upload a customer email list to Meta for lookalike audiences, GDPR requires explicit consent for that specific use. CCPA requires you to disclose that data sales are happening and allow consumers to opt out, but the threshold for consent is lower.
The safest approach: treat all customer data as if GDPR applies, even if your primary market is California. This covers you for both regulations and reduces the complexity of managing segmented consent flows across different platforms.
Consent Mechanisms: Cookie Banners and Email Opt-Ins
Your compliance strategy lives in two places: your cookie banner and your email signup flow.
Under GDPR, you must obtain consent before non-essential cookies load. This means your Shopify store needs a banner that blocks Google Analytics, Meta Pixel, and other third-party trackers until the customer clicks "Accept." Rejecting must be as easy as accepting. Email signups also require explicit consent—pre-checked boxes violate GDPR.
CCPA doesn't mandate a pre-loading cookie banner, but California residents still have the right to know what data is collected and to opt out. Many brands implement GDPR-style banners anyway because it's easier than building two different systems.
Your email marketing platform (like Klaviyo) needs to respect these preferences. If someone rejects non-essential cookies or unchecks email consent, your automations should honor that choice. Some Shopify apps sync consent preferences directly with Klaviyo, but you need to verify this is working—many stores accidentally email people who never consented.
Test your setup: go through your signup flow with a fake email, reject cookies, then check whether you receive marketing emails. If you do, you have a consent leakage problem that could trigger complaints or audits.
Data Subject Rights and Customer Requests
Both GDPR and CCPA give your customers the right to request, access, and delete their personal data. These are called "Data Subject Access Requests" (DASARs) under GDPR and "consumer requests" under CCPA.
Your brand needs a process to handle these requests. A customer emails asking for all the data you hold about them—you typically have 30 days (GDPR) or 45 days (CCPA) to respond. You must pull data from your Shopify store, email platform, analytics tools, and any third-party services that store customer information.
For a DTC brand, this is operationally complex. You might store data across Shopify, Klaviyo, Okendo, Gorgias, and your payment processor. Manually gathering and responding to requests is error-prone and slow. Many brands use dedicated DSAR software or work with their CMP (consent management platform) to automate request collection and tracking.
GDPR also requires you to delete data when a customer requests it, while CCPA requires deletion "to the extent commercially feasible." That gray language under CCPA has led to fewer deletion requests, but don't assume you can ignore them—California enforcement is increasing.
Start documenting which systems hold customer data and how long you retain it. This prep work makes handling requests faster and safer when they arrive.
What Happens If You Get It Wrong
Non-compliance carries real financial and operational consequences that go beyond fines.
GDPR enforcement is aggressive. The EU's data protection authorities can levy fines up to €20 million or 4% of global annual revenue—whichever is higher. More commonly, brands face smaller fines (€5,000–€100,000) for cookie banner issues or consent problems. Even without fines, investigations are disruptive: regulators request documentation, audit your systems, and can order you to stop processing data until you fix violations.
CCPA enforcement is growing. California's Attorney General and private litigants can sue. Fines start at $2,500 per violation ($7,500 if intentional), but many settlements have reached six figures. Unlike GDPR, California also allows private right of action for data breaches—customers can sue directly if their unencrypted personal information is compromised.
For eCommerce brands, the reputational hit often matters more than the fine. A compliance violation becomes a customer trust issue. Even smaller brands that think they're "too small to audit" can face complaints from a single privacy-conscious customer, triggering a formal investigation.
The easiest protection: implement a system that logs and documents your consent practices. When you can show regulators
