- "Keep responses on this form for 90 days only."

Every form can carry a **retention window** (in days). Responses older than the window — including their uploads — are purged automatically; nothing to remember, nothing to script.

No window set means responses are kept until you delete them or the form. Set or change it any time in one sentence.
