Privacy Law Comparison - Which Laws Apply to Your Site

Home / Everything About / Everything About Analytics / Privacy Law Comparison - Which Laws Apply to Your Site

All major privacy laws share core principles—consent, transparency, data minimization, security, and user rights. But they differ in scope, enforcement, and penalties. Understanding how they compare helps you identify which apply to your business and design a compliance strategy that covers multiple frameworks simultaneously.

Core Principles Across All Privacy Laws

Every major privacy framework (GDPR, CCPA, LGPD, PIPEDA, etc.) requires some version of: transparency about data collection, permission before collecting most personal data, keeping only what's needed, protecting data from misuse, and giving individuals rights over their own information. These are not debatable. If you respect these principles, you're compliant with most frameworks.

The Differences That Matter

Consent model: GDPR requires explicit opt-in consent for most tracking. CCPA uses opt-out for data sales (but is moving toward opt-in). Most newer laws follow GDPR's opt-in model.

Personal data definition: GDPR and others define personal data broadly. CCPA is even broader. Broadly defined means more data triggers compliance requirements.

Scope of applicability: GDPR applies to EU residents. CCPA applies to California residents. LGPD applies to Brazilian residents. Multiple laws may apply to the same user based on where they are or where your business operates.

Penalties: GDPR: up to 4% of revenue. CCPA: $2,500-$7,500 per violation. LGPD: up to 2% of revenue. Penalties are severe across the board.

Enforcement: GDPR has active, aggressive enforcers (national regulators). CCPA enforcement is growing (state AG, private right of action). LGPD enforcement is ramping up. Most laws are actively enforced.

Detailed Comparison: GDPR, CCPA, LGPD, PIPEDA

Consent

GDPR and LGPD: explicit opt-in required. CCPA: opt-out for data sales (but CPRA moves toward opt-in for sensitive data). PIPEDA: opt-in for most purposes. Winner for strictness: GDPR and LGPD.

Personal Data Definition

GDPR: anything that identifies a person directly or indirectly. CCPA: broader—includes inferences and predictions. LGPD and PIPEDA: similar to GDPR. Winner: CCPA is broadest.

User Rights

All require: access, deletion, and portability. GDPR adds: right to rectification, right to restrict processing, right to object. CPRA adds: right to correct, right to limit use. PIPEDA less explicit but similar. All are strong. GDPR/CPRA most comprehensive.

Data Minimization

GDPR, LGPD, PIPEDA: explicit requirement to collect only what's necessary. CCPA: less explicit. GDPR wins for strictness here.

Security and Breach Notification

All require reasonable security. GDPR: notify regulators within 72 hours. CCPA: notify individuals within 30 days (no regulatory requirement, but AG notification often required). LGPD and PIPEDA similar to GDPR. GDPR strictest on notification timeline.

Determining Your Compliance Obligations

Step 1: Map Your Visitor Geography

Use your analytics to identify where your traffic comes from. If visitors are from EU, GDPR applies. If from California, CCPA applies. If from Brazil, LGPD applies. Most sites have visitors from multiple jurisdictions, triggering multiple laws.

Step 2: Check Company Operations

Do you have offices, employees, or business partners in regulated jurisdictions? This can trigger applicability even without website traffic (e.g., a company with EU employees processing customer data may trigger GDPR regardless of website traffic).

Step 3: Identify the Strictest Applicable Law

Among all laws that apply to you, which is strictest? Typically GDPR. Build compliance to that standard and apply it universally. This is simpler than per-jurisdiction compliance.

Step 4: Add Regional Variations

Some regions require specific mechanisms (e.g., data localization in some Asian countries, explicit CCPA opt-out buttons in California). Add these to your base-case compliance approach.

The Pragmatic Approach: GDPR as a Baseline

For most companies, the practical approach is: assume GDPR applies (it usually does unless you're purely domestic to a non-regulated region), build to GDPR standards, then layer on regional requirements. GDPR compliance almost always exceeds most other frameworks. This reduces complexity and ensures you're never out of compliance.
