Is there Anyway I can retrieve lost or deleted footage?
Good question @Jenna2! At Ring we value our neighbors security and privacy. When subscribed to one of our Protect Plans, the recordings are entirely your and only stored on your account. If videos are deleted, or a subscription lapses, these recordings do not exist anywhere else for them to be recovered.
For this reason, we highly recommend not only starring certain videos, but also downloading the most important recordings. I hope this helps!
