Budget cuts are coming and you need to know what is lost, and when, if the subscription ends.
Canceling stops the next renewal; you keep access until the end of the paid period. After a downgrade, a 30-day grace window applies before higher-tier storage is purged, so nothing disappears on the day you cancel. Separately, captures past their retention window are cleaned up nightly regardless of plan, which is why permanent captures should be downloaded.
Cancel when ready and work until the period ends. Before the 30-day grace expires, download anything in higher-tier storage you need to keep, and export templates if you are moving to a plan where they no longer sync.
