It gives you a trial for about a week, and then it holds your photos captive from you until you pay. I am absolutely livid right now. Responding to the response I received. It is not free. I had to pay to get my pictures back. It literally would not let me access my pictures until I paid. Anyone reading this, if you are expecting an actual free photo lock app, it is not free. Do not download.
Very good and easy to work with! It’s perfect for me to protect photos! 5 stars
