If I delete my Deployment, does my data get deleted?

No. The Deployment only manages Pods. The Persistent Volume (PV) and Persistent Volume Claim (PVC) are separate API objects with their own lifecycle. If you delete the Deployment, the Pods die, but the PV and PVC remain perfectly intact.

What happens if I delete the PVC?

This depends on the `reclaimPolicy` of the Persistent Volume. If it is set to `Retain`, the physical data on the disk is saved, but the volume is marked as 'Released'. If it is set to `Delete` (which is often the default for dynamically provisioned cloud storage), deleting the PVC will trigger an API call to AWS/GCP to completely destroy the physical disk and all data on it. Be extremely careful!
