Frameo digital picture frame privacy

I want to get my wife a digital picture frame. Just a little screen that we can add pictures to. Nothing too complicated.

Half of them out there run on frameo. A friend of mine has a frameo, it seems nice. The privacy policy isn't great. Facebook, Google, the usual offenders. Supposedly, it's end to end, so the pictures are secure. I don't know and that

Is there a decent alternative? I'm not against going with a flash drive, if that's my only option.
