Data Retention, Deletion and Preservation Policy

Retention principles

• Define purpose-linked retention rather than indefinite storage by default.
• Delete or anonymize data when the purpose expires unless preservation is justified.
• Preserve records subject to legal hold, active disputes, fraud/abuse investigation or security needs.
• Backups and replicated systems may follow separate bounded deletion cycles.

Editorial records

Public correction history and private editorial/audit evidence serve different purposes. Private prompts, moderation evidence and security-sensitive data should not be exposed merely because a public article exists.
