How this is applied in-product

  • Scheduled deletion jobs for expired records
  • Public retention statement at /privacy
  • Immutable KERI credentials retained by design; PII never anchored

1. Retention Table

  • Account profile - retained while account is active plus 24 months after closure, then anonymised.
  • Donation records - 7 years after the tax year of receipt (IRD, HMRC, IRAS compatible).
  • AML/KYB evidence - 5 years after the end of the business relationship.
  • Audit logs - 3 years, then aggregated and pseudonymised.
  • Support tickets - 2 years.
  • Marketing consents - until withdrawn plus 12 months evidentiary window.
  • KERI credentials (ACDCs) - retained indefinitely as tamper-evident public artefacts; contain no personal data.

2. Deletion Triggers

  • User-initiated erasure request via /privacy.
  • Retention period expiry via scheduled job.
  • Legal or regulatory hold overrides deletion until the hold is lifted.

3. Backups

Encrypted backups are retained for 35 days on a rolling basis. Deletion requests are honoured in production immediately and in backups within the standard rotation window.
