Common Mistakes

  • 1 Passing personal data (emails, names) as user attributes when anonymous keys would suffice for flag evaluation
  • 2 Not distinguishing between operational feature flags (functional) and user-targeting experiments (analytics)
  • 3 Using client-side evaluation when server-side would avoid transmitting user context to LaunchDarkly

Compliance Considerations

Feature flag evaluation can be performed server-side without collecting personal data. Client-side SDKs transmit user context (keys, attributes) for flag evaluation. When used purely for operational feature toggling, a functional/legitimate interest basis is appropriate. When used for user-targeting experiments, analytics consent may be required.
