Event media, meaning photos, videos and voice notes, is permanently deleted once the event's plan runs out of storage. On a paid plan that is twelve months from the day the event was created. On the free event it is four weeks.
The free event is a taste of the product, not a place to keep things. Four weeks is long enough to come back for the album and deliberately not long enough for anyone to mistake it for a backup. If you want your photographs to last, run the event on a paid plan or download them.
Either way the event and its records remain, but the files themselves are gone and cannot be recovered.
The demo event on our homepage is wiped every twenty-four hours. It is a shop window, not anybody's memories.
A host who deletes their account removes everything: their events, every photo, video and voice note behind them, their guest lists, unused plans and payment records. There is no grace period and no undo, which is why the form asks for a password and the address typed out in full.
