Privacy Policy

PDF Doc Scan for Android (called “ScanX” inside the app, the “App”) is a document scanner and PDF editor made by Bytesong Private Limited (“Bytesong,” “we,” “us,” “our”). This policy explains what the App does with your information. It covers the Android app only.

1. The short version

• Your documents, scans and their text stay on your device. We have no server and you need no account.
• There are no ads, and the App has no analytics or crash-reporting tools of its own.
• Scanning and text recognition run on your device using Google ML Kit. ML Kit sends Google some technical information, never your documents. See section 4.
• Subscriptions are handled by Google Play. We never see your payment details.

2. What the App stores on your device

The App keeps the following in its own private storage on your device:

• Your documents, page images and PDFs, and files you import (PDFs, photos, and Word, Excel, PowerPoint, text, CSV and RTF files, which are converted to PDF on your device).
• Text recognized from your pages.
• Folders, document names, signatures, watermark text and your edits.
• Your settings, your subscription status, and the PIN you set to lock documents.

None of this is sent to Bytesong or anyone else.

3. Permissions the App uses

• Camera — for the ID card and passport screen. Document scanning uses Google's scanner, which runs its own camera inside Google Play services.
• Fingerprint or face unlock — to open locked documents and folders. Android checks your fingerprint or face. The App never receives your biometric data.
• No storage or photo permission. When you pick a photo or file, Android's own picker gives the App only the items you choose. If you turn on Auto-Save, the App writes PDFs only to the folder you pick.
• Internet — used by Google Play services for ML Kit, purchases and the rating prompt. The App itself does not send your content anywhere.

4. Google ML Kit (scanning and text recognition)

The App uses Google ML Kit, through Google Play services, to find page edges, scan documents and recognize text. Your images and text are processed on your device and are not sent to Google.

To keep ML Kit working and to improve it, Google may collect:

• Device information, such as manufacturer, model, Android version and build.
• The App's package name and version.
• Per-installation identifiers that are not meant to identify you or your device.
• Performance figures (such as how long a scan took), settings (such as image size), event types and error codes.

Google encrypts this data in transit and says it does not pass it to third parties. Details: ML Kit data disclosure and the Google Privacy Policy.

5. Purchases

If you buy a subscription, Google Play handles the payment under your Google Account. We never see your payment details. Google Play tells the App only whether your subscription is active.

6. Ratings

The App may ask you to rate it, using Google Play's in-app review window. Anything you submit goes to Google Play under Google's terms, not to the App.

7. Sharing and exporting

When you share or save a document, it goes only where you send it, such as email, a messaging app, Google Drive or a folder on your device. What happens after that is covered by that service's own privacy policy.

8. Keeping your documents

The App does not upload your documents to any cloud. If you lose your device or uninstall the App, its documents are gone. To keep copies, share or save them elsewhere, or use Auto-Save to a folder you choose.

9. Children

The App is not intended for children under 13. Bytesong does not collect data from anyone, including children.

10. Deleting your data

• Delete a document or folder inside the App to remove it.
• Uninstalling the App removes everything it stored.
• Files you shared or saved outside the App stay where you put them.

11. Changes

If this policy changes, we will update the date at the top of this page and the policy linked from the App's Google Play listing.
