Customer Impact

What This Means For You

Hotels and airlines using Sojern face session recording liability exposing guest PII and payment flows. Identity resolution creates persistent profiles linking travel searches across competitive properties. Tag manager enables Sojern to add tracking partners without customer awareness or consent.
Recommended Actions

What To Do About It

Role-specific actions based on observed behavior

If You Use Sojern

  • Audit Sojern tag manager for unauthorized third-party additions
  • Implement session recording suppression for payment/PII entry flows
  • Review identity resolution opt-out mechanisms and data deletion procedures

If You're Evaluating Sojern

  • Document session recording scope and retention policies
  • Request written confirmation that travel intent data is not sold to direct competitors
  • Obtain technical specification for disabling identity resolution per-visitor

Negotiation Leverage

  • Session recording: Full replay captures sensitive booking flows — require PII/payment redaction and explicit session recording consent.
  • Identity resolution: Cross-property profiling links travel intent — negotiate competitor exclusions and demand data deletion rights.
  • Tag manager control: Dynamic partner additions bypass customer oversight — require approval workflow for all third-party additions.
  • Data sales: Travel intent signals sold to competitive properties — demand transparency on buyer identity and exclusion rights.
