- Payload hash (for change detection)
Hard deletion (60 days)
If a sync hasn’t executed for 60 days, all associated records (payload + metadata) are permanently deleted.These policies ensure sensitive data isn’t stored indefinitely. If you need to access record payloads long after updates (30+ days), please reach out in the Slack community.
