GDPR vs CCPA: What SaaS Founders Need to Know in 2026

GDPR and CCPA are the two most-cited privacy laws in the world. Most SaaS founders have heard of both. Fewer understand how they actually differ — and the differences matter for how you build consent flows, write your privacy policy, and handle user data.

Who They Protect

GDPR protects any natural person in the EU or EEA, regardless of citizenship. If someone with an EU IP address uses your product, GDPR applies. CCPA protects California residents specifically. A California resident traveling in Europe is covered by CCPA; an EU citizen visiting California is covered by both.

Who Must Comply

GDPR has no revenue threshold — if you process EU personal data, you must comply. CCPA applies only to for-profit businesses meeting at least one of: $25M+ annual revenue, 100,000+ consumers' data processed annually, or 50%+ revenue from selling personal information.

Consent Requirements

GDPR requires opt-in consent for non-essential cookies and most marketing. Pre-ticked boxes are explicitly prohibited. CCPA uses an opt-out model for data sales — you can collect by default, but must offer a clear 'Do Not Sell My Personal Information' link.

Practical Takeaway

For most SaaS products, building to GDPR standard covers CCPA as well — GDPR is more demanding. The main CCPA-specific obligation most founders miss is the 'Do Not Sell' link, which applies even if you are not actively selling data (sharing for advertising counts as 'selling' under CPRA).
