I have used photo album locks before, mainly because Im one of those people that has family and friends go through my photos specifically when they have a hold of my phone. And there are some privacy issues... having worked in a bank, sometimes we needed to keep codes on us and secure.... if theres any racey selfies lol, you might not want that exposed. The best part... memories, you can delete things from your regular album and it does it for you with your permission.... and then you can use the locked album to revisit when you want instead of constant reminders of things that may upset you. It took less than two minutes for me to download, install, and set up this app. So far, so good!
