This Privacy Policy explains how the mobile application PDF Scanner - Document Scan (the "App") handles your information. By installing and using the App, you agree to the practices described here.
The App does not require an account and does not ask you for personal information. Data falls into two categories:
Firebase never receives your scans, your PDFs, the text recognised in them, or any file names or document titles you enter.
The App requests the following permissions only to provide its core features:
CAMERA) — Used to capture photos of your documents inside
the App's scanner. Camera images are processed on your device only. We do not record video and do
not upload camera data anywhere.
READ_MEDIA_IMAGES,
READ_MEDIA_VISUAL_USER_SELECTED on Android 14 and newer, and
READ_EXTERNAL_STORAGE on Android 12 and older) — Used to show the App's own gallery
grid so you can pick existing images to import into a document. Images are read from your device
to display and import them locally; they are never uploaded. On Android 14 and newer you may
grant access to selected photos only, and the App will show just those.
INTERNET,
ACCESS_NETWORK_STATE) — Used only to send Firebase Analytics and Crashlytics data,
and to download an optional higher-accuracy document-detection model on unmetered connections.
Scanning, enhancement, OCR and export all work fully offline.
com.google.android.gms.permission.AD_ID) — Declared
by the Firebase Analytics SDK. See Section 4 for how to reset or opt out.
You can grant or revoke camera and photo permissions at any time in your device Settings. If a permission is denied, the related feature (camera scanning or gallery import) will be unavailable, but the rest of the App continues to work.
The App uses Google Firebase Analytics and Google Firebase Crashlytics, services of Google LLC, to understand how the App is used in aggregate and to diagnose crashes so we can fix them. Data is processed by Google as our service provider and is governed by Google's own policies:
Your choices: you can reset or delete your Advertising ID, or opt out of ad personalization, in your device Settings under "Google" → "Ads." Resetting the Advertising ID breaks the link between previously collected analytics data and your device.
We do not sell this data, we do not use it for advertising, and we do not combine it with any other source to identify you personally.
All image enhancement and document intelligence happens locally on your device, with no network connection for these features:
Your scanned documents and their contents are never transmitted off your device by the App.
Your scans, PDFs, annotations and app preferences are stored only in the App's private storage on your device. This data is under your control: you can delete individual documents or clear everything from within the App, or by uninstalling the App. Uninstalling removes all documents and settings stored by the App.
Android Auto Backup: the App deliberately excludes your documents, annotations and document database from Google cloud backup, so your scans are not copied to your Google Drive. Only lightweight app settings are eligible for cloud backup. When you move to a new phone using Android's direct device-to-device transfer, your documents are carried across locally.
Diagnostic data collected by Firebase is retained according to Google's own retention policies.
The App lets you export or share PDFs, images and extracted text through your device's standard share sheet (for example to email, cloud storage, messaging, or printing apps). When you choose to share a file, it is handled by the app or service you select, and that service's own privacy policy then applies. This sharing is always initiated by you.
The App is a general-purpose utility and is not directed at children under 13. We do not knowingly collect personal information from children. If you believe a child has provided us with personal information, please contact us and we will delete it.
Your documents stay on your device and are protected by your device's own security (screen lock, encryption, and OS protections). We recommend keeping your device secured and up to date. Diagnostic data transmitted to Firebase is sent over encrypted connections and protected in accordance with Google's security practices.
The App uses open-source and Google libraries. The following process data on-device only and do not transmit your documents off the device: AndroidX, OpenCV, ONNX Runtime, and Google ML Kit Text Recognition. The App also uses Google Firebase Analytics and Google Firebase Crashlytics, which transmit the diagnostic data described in Section 4. The App does not include any advertising SDK.
We may update this Privacy Policy from time to time. Changes will be posted on this page with an updated "Last updated" date. Continued use of the App after changes take effect constitutes acceptance of the revised policy.
