Can I share abandonment data with third parties?

As an e-commerce founder, data privacy keeps me up at night. I'm constantly balancing the need to understand customer behavior with strict legal compliance. Recently, I've been exploring how we handle visitor abandonment data and wondering about the legal implications of sharing this information. My team tracks numerous metrics—page views, cart additions, checkout initiations—and I want to ensure we're not inadvertently violating any data protection regulations. We're a growing Shopify store, and while understanding customer journeys is crucial for optimization, I'm acutely aware that mishandling personal data could result in significant legal and reputational risks. GDPR in Europe, CCPA in California, and emerging global privacy laws make this a complex landscape. I need clear guidance on what abandonment data we can collect, how we can analyze it, and most critically, under what circumstances (if any) we can share this sensitive information with third-party vendors or analytics platforms. The stakes are high—a single misstep could mean hefty fines or losing customer trust. I'm looking for a comprehensive, practical approach that protects both our business insights and our customers' privacy rights.
