Session Replay data retention limit exceeds documented default

Goal

Determine the upper bound on the retention period for Session Replay data in Microsoft Clarity and how to confirm it.

Constraints

Clarity’s default retention is 30 days; the UI offers an override but the maximum value is not publicly documented, and no API exposes the cap.

Unresolved behavior

When the retention setting is changed to 90 days, the dashboard reflects 90 days, yet after 31 days the replay data disappears, suggesting a hidden limit.

Questions

• What is the maximum retention period that can be configured for Clarity Session Replay data?
• Does Clarity enforce a hard cap on the override value, and if so, what is that cap?
• What method can be used to verify that the configured retention period is actually applied and that data is not purged earlier than expected?
