Frequently Asked Questions
Is business card information subject to privacy laws?
Yes, information on business cards is personal information. However, if you're simply keeping business cards for personal social purposes, business obligations may not apply. But if you add them to a customer list for sales purposes, privacy obligations apply.
Is using Google Analytics problematic?
Google Analytics handles anonymized data, but you should still disclose your use of cookies and analytics in your privacy policy. GA4 no longer stores IP addresses, which addresses some previous concerns.
What should I be careful about with email marketing?
Beyond privacy laws, you must also comply with anti-spam laws (like CAN-SPAM). Prior consent is required, unsubscribe mechanisms must be provided, and sender information must be clearly displayed.
How should I handle data received from clients?
When handling personal data as a contractor, you're acting as a "data processor" and must implement security measures under the client's oversight. Clearly define handling rules in your contract.
Summary: Privacy is the Foundation of Trust
Privacy protection is both a legal obligation and the foundation for earning customer trust. Proper compliance allows you to confidently grow your business.
