I don’t have much room in my iCloud storage, so, I paid for a month subscription and put all 2,000+ photos on my phone into PrivateVault hoping I could transfer it over to my new phone and they never transferred. YOU CAN’T even move groups of photos out, you have to do it one at a time.. I tried downloading PrivateVault on the new device to see if I could just use my passcode and get in. No. It just set up a new “vault” I’m sincerely disappointed and want my money back.. those photos were important to me, and I lost them trying to trust PrivateVault.
The flip side, it is a good disguise and hides your photos from other people. They never suspect that your photos are in a calculator. Lol!
So, if you don’t plan on moving phones and use PrivateVault as a moving tool, I think you’ll be fine.
