  • Purpose: Provide voice-based tour guide functionality, manage subscriptions, personalise experience, improve app, marketing.

2. Necessity and Proportionality

  • Children risk (if under-13s bypass age gate).

4. Mitigations

  • Supabase encryption at rest plus TLS in transit.
  • Retention schedules:
    • Account: 3 years post-deletion.
    • Billing: 6 years.
    • Voice: 12 months (ElevenLabs up to 3 years).
    • Location logs: 12 months.
    • Analytics logs: 12 months.
    • Crash reports: 6-12 months.
  • Age gate at signup (13+ only).
  • Unsubscribe links plus in-app toggle for marketing.
  • Data subject request procedure with 1-month turnaround.

5. Outcome
