Pulseri Pulseri now removes expired operational data automatically each day, in one place for every table. Audit events older than your plan's period are deleted, as before. Delivery records are reduced to the counts you see in reports once they age out. When you erase a person, their name, email and traits are scrubbed from the raw copies of their events too, so nothing personal outlives the person.
See Privacy for how long each kind of data is kept.
