Frequently Asked Questions

Why do document apps need storage permissions on my phone?

Document apps require storage permissions to locate, open, edit, and save files directly to your phone's internal memory or an external SD card. Without this access, they cannot interact with your local files.

Can I revoke file access permissions after granting them?

Yes, you can revoke file access at any time by navigating to your phone's Settings > Apps > [App Name] > Permissions, and selecting 'Don't allow'.

What happens if I deny file access to my PDF reader?

If you deny storage permissions, the app will not be able to browse or open local files saved on your device. You may only be able to view documents hosted on connected cloud services.

Is it safe to grant 'Allow management of all files' to an app?

You should only grant full file management permissions to trusted applications, such as reputable file managers and official document editors like WPS Office, to ensure your personal data remains secure.
