No, we will never charge any fee to backup your devices to your Picture Keeper drive. The apps are free, and no membership or subscription is needed to backup, view, or restore your files.
We do offer KeepSafe, an optional subscription that stores an extra copy of your photos, videos, and contacts on Picture Keeper's private servers — so your files exist in two places even if the drive is ever lost or damaged. It is entirely optional; your drive works exactly the same without it. Learn more in the KeepSafe Overview.
