Deleting your account removes your sign-in immediately. Base44 keeps the deleted account and the records this app removed in Recently deleted for 30 days, where an app editor can restore them. After 30 days they are permanently deleted. This is not instant physical erasure. Protocols you created are deleted. Device, media, and pairing rows are deleted only when their created-by id is your account. Anonymous device records are not tied to the login in this app, so a device id sent from the browser is ignored. Saved device tokens and on-device phrases on this browser are cleared after a confirmed deletion.
