About File Locker - Prevent access to file
File Locker allows you to prevent unwanted access to your private files with PIN, pattern lock.
★ How it works?
This app locks file by encrypting the file content with the password and then hiding the encrypted file. It does not move the file to another folder. So if you delete the folder, the locked file will be deleted as well.
Please read descriptions below carefully before using this app.
Features:
★ Safe and easy to use
★ No annoying ads
★ No internet access
★ No dangerous permissions
★ Support Android 5.1 and up
★ Use Advanced Encryption Standard to lock files with password
★ Advanced security settings:
- Prevent uninstalling File Locker by activating its device admin
Please NOTE that:
• This app locks file by encrypting the file content with the password and then hiding the encrypted file. It does not move the file to another folder. So if you delete the folder, the locked file will be deleted as well.
• This app does not use INTERNET permission, so it is not able to access the internet. Therefore, it cannot connect to a remote server to steal your data. So, please feel safe to use!
If you have any questions, suggestions or bugs, please contact me at [email protected]
FAQ:
• How if I forget the lock screen?
Because this app doesn't want to use Internet access (for your privacy), so it doesn't support password recovery via internet such as email.
If you forget password, you can clear app data or re-install app to reset password.
But if you cannot recover the old password, you will not be able to unlock the files locked before.
So please try to not forget the password!
