Soft-deleted documents30 days by default (SOFT_DELETE_RETENTION_DAYS)cleanup-soft-deleted-documents cron
When you delete a document, it is first soft-deleted. The cleanup-soft-deleted-documents cron permanently removes soft-deleted documents after the configured retention window. The default is 30 days.

​
Audit logs

Security-relevant actions (authentication, role changes, deletions, billing events) are written to an append-only audit.audit_log table. Retention is operational policy: the audit log is not pruned by any cron job in the codebase today.

​
Account deletion

When you delete your account, all your data is permanently removed: documents, folders, memories, clusters, content chunks, and OAuth tokens. This is irreversible. Deletion is recorded in the audit log.

​
Backups

The PostgreSQL database is hosted on Neon, which provides point-in-time restore plus snapshot history. Backup schedule and retention is operational state and may change — when in doubt, contact support for the current values rather than relying on this page.
