When does Optimizely trigger privacy obligations?
Installation triggers cookie and tracking obligations
The moment you add Optimizely's SDK to your site or app, the `optimizelyEndUserId` cookie is set and visitor attributes, experiment exposures, and conversion events begin flowing to Optimizely's US servers. This immediately triggers:
GDPR (EU/UK visitors): Article 82 (cookies) and Article 6 (lawfulness) obligations apply. The ePrivacy Directive Article 5(3) requires explicit prior consent before non-essential cookies are placed. Optimizely's cookie is not technically essential—it serves analytics and experimentation—so you must obtain affirmative consent *before* the SDK loads, not after.
