Data Collection Principles ​

What We Collect ​

  • Anonymous identifiers: Random strings to maintain test consistency
  • Experiment participation: Which tests a user is enrolled in
  • Variation assignment: Which version of a test the user sees
  • Conversion events: Anonymous goal completions and interactions

What We DON'T Collect ​

  • Personal information: No names, emails, IP-addresses or identifying data
