5. Legal Basis for Cookie Use

GDPR (EU/EEA): Essential cookies are placed under legitimate interests. All non-essential cookies (analytics, marketing, functional) are placed only after you provide explicit opt-in consent via our consent banner.

CCPA (California): We classify marketing cookies as potential "sharing" for targeted advertising under CCPA § 1798.140(ag). California residents may opt out via our Do Not Sell page or by rejecting marketing cookies.

ePrivacy Directive: Our cookie use complies with the EU ePrivacy Directive (2002/58/EC) as implemented in national law.

6. Updates to This Cookie Policy

We may update this Cookie Policy as our cookie practices evolve or as legal requirements change. We will notify you of material changes via the cookie consent banner. We recommend reviewing this page periodically.
