PDF Fusion adheres strictly to the principle of least privilege, requesting only the permissions necessary to deliver the features you choose to use.
| Permission | Technical Name | Why It Is Needed |
|---|---|---|
| Camera | android.permission.CAMERA |
Requested only when you use the Document Scanner to capture physical documents. Camera frames are processed strictly in device memory. |
| Storage & Media | READ_MEDIA_IMAGES / READ_EXTERNAL_STORAGE |
Used via Android's Storage Access Framework (SAF) to let you select files and save processed PDFs. The App only accesses the files you explicitly select. |
| Internet & Network | INTERNET, ACCESS_NETWORK_STATE |
Required exclusively by the Google AdMob SDK to request and display advertisements. Zero document data is ever transmitted. |
* We do not request or use broad file manager permissions (MANAGE_EXTERNAL_STORAGE).
