Pillar 09
Privacy & Data Lifecycle
Understand what happens to Free temporary-inbox data from active use through expiry, the 24-hour closed-inbox retention window, and eventual purge.
MailOnce separates an inbox becoming unavailable from its later physical purge. For Free inboxes, expiry or deletion closes the address first; closed inbox data becomes eligible for hard purge after exactly 24 hours. These guides explain that lifecycle without claiming instant deletion or permanent storage.
