Data retention
How long KaizoCore keeps decision logs, journey data, and training data — and why.
Retention windows
| Data | Retention | Why |
|---|---|---|
Decision log (decisions) | 18 months | Matches common industry audit-trail expectations for fraud/risk decisions. |
| Journey snapshots (per-page-view data) | 90 days | Short-lived by nature — feeds real-time journey confidence during a session, not a long-term audit need. |
| Ground-truth ML training data | Retained indefinitely | The scarcest and most valuable data KaizoCore has. Pruning this is a separate, deliberate decision, never an automatic one. |
Cleanup runs on a daily schedule and only ever deletes rows past their window — nothing is retained shorter than the table above without an explicit, separate decision to change it.
What's in a decision log row
IP, user agent, event type, entity keys, score, decision, fired reasons, and a device fingerprint hash — enough to investigate and correlate. This is accessed via the dashboard's Session Explorer or the API; KaizoCore doesn't offer direct database access.
