Baselines are different from history. The latest successful text baseline remains while the monitor exists so the next check has a comparison point. Active visual baselines are renewed; an unrefreshed visual baseline expires after 90 days.
Previews expire sooner. Stored setup preview HTML and visual-preview access expire after 15 minutes. Background cleanup removes expired records and image objects afterward.
Changing plans affects access. A downgrade applies the shorter history window immediately. Upgrading cannot restore captures that cleanup has already deleted. Visual access also depends on feature and trial allowances.
Service records have other periods. Completed notification delivery logs are kept for seven days; bounded readiness totals for 90 days; monthly usage totals for up to 13 calendar months. The privacy policy covers account, session and other operational records.
