This is an interesting app that's using illusionary tricks such as camouflage which is seen in nature itself for certain animals to survive in the wild. What an interesting app to find here! Thank you!

I accidentally permanently deleted all my photos and videos in Calculator Lock. The app is still installed, my PIN works, and I found files in .hideHiderAlbum/.private that won't open. Can you help me recover them?

Hello. Thank you for contacting us. If you previously enabled cloud backup in the app, log in to the same Google account to open Google Drive and download the files. If not, permanently deleted files cannot be recovered. This is the design intent of the app. We understand the importance of your data and apologize.🄺

Hi Prattyaksh, we're sorry to hear about your files. Our app never deletes anything without permission, and they might be removed due to manual deletion, a cleaning tool, or a device change or reset. You can try opening the File Manager, enable "Show hidden files," then check ".hideHiderAlbum/.private." Let us know if you need more help.
