Comments on Lock my Folder - Folder hider for Android

★★★★★ Dr. Terror · May 7, 2026
So far, so good, but I cannot find a way to back up the app to, say, be able to reinstall it in case I need a new mobile phone.
★★★★☆ David Ingti · Apr 28, 2026
So far okay, does the job as expected but the app UI should upgrade for better viewing user experience
★★★★★ Jay Sørsdahl · Jan 22, 2026
I actually quite like this app, took a bit for me to figure out how to actually add pictures to files purely by fault of my own, It's really good for hiding my... homework...
★★★★☆ Когда мое сердце разбилось · May 2, 2026
Good app. In my opinion, it would be better if they added an option to delete everything, so that if I don't run the app for a day or 3 hours, the data is deleted immediately . Due to the high the mobile's phone thefts during this period
★☆☆☆☆ Imran Khan · Feb 4, 2026
Dears don't install this application, it's unsafe to protect data. I hide some of my personal data in this folder, After few days some of the data missing, even I haven't deleted them, So it's looks here privacy compromised. Don't trust this application. I need explanations of this. It's looks they are sharing personal data to third party.
★☆☆☆☆ Johannes Matheus Hausiku · Mar 1, 2026
I forgot my pin! But then when I tried to reset it, I never receive any pin guidelines in my email. Now all my files are gone.
