As Tom_Ring mentioned above,
“Any private videos stored in the cloud are automatically deleted following the expiration of your account’s applicable storage period under the Ring Protect Plan. We’ve developed a feature that allows you to delete videos from previously shared video links, which you can learn more about here.”
You can also adjust your video storage length options, in which our Community article has steps and tips on doing so. If you are needing further assistance with video storage, please give our support team a call at one of the numbers available here. If you are outside of the US, please visit here to see how to contact support.
