How does Scandroid work?

Scandroid uses the Document Scanner API from Google ML Kit. This API runs entirely on-device as part of Google Play Services — no internet connection is needed to scan documents. Scans and metadata are stored locally using the device’s internal storage and an embedded SQLite database. You can see a full list of libraries used in Settings → About.

Why does Scandroid require no permissions?

The entire scanning process is delegated to Google Play Services, which operates at the system level. Because Scandroid never directly accesses the camera or file system APIs, it needs zero permissions. Your photos and documents are never touched by the app itself.

Where are my scanned files stored?

All images and PDF documents are saved in app-specific internal storage on your device. This storage is not accessible to other apps. Files only leave the app when you explicitly tap Share — at that point, only the target app receives a one-time permission to read that specific file.

What analytics data is collected?

Scandroid uses Firebase and Google Analytics to collect basic, anonymous usage data. No information about your scans or documents is ever collected. The data collected is limited to:

  • Screen views
  • User interactions (button taps, feature usage)
  • Crash logs
  • Performance metrics

All analytics can be disabled in Settings → Privacy.

Is the app really free?

Yes. The core scanner functionality is free and will remain free. Optional premium features may be introduced in the future, but the essential scanning, saving, and sharing features will always be available at no cost.

How do I contact support?

You can reach the developer at contact@scandroid.app.

Does Scandroid work without an internet connection?

Yes, Scandroid is fully offline. The Document Scanner API from Google ML Kit runs entirely on-device as part of Google Play Services. You can scan, edit, save, and export documents at any time — no Wi-Fi or mobile data required.

Can I export scans as PDF?

Yes. Every scan can be exported as a multi-page PDF document or as individual JPEG images. You choose the format when sharing or saving from the scan details screen.

Is Scandroid safe to use?

Yes. Scandroid never uploads your documents to any server. All scanning and processing happens on your device, scanned files are stored in app-specific internal storage that other apps cannot access, and the app does not request camera or storage permissions.

Yes. In addition to scanning new documents with the camera, Scandroid lets you import existing photos from your gallery. Imported images go through the same perspective correction, cropping, and editing workflow as freshly captured scans.

How does Scandroid handle perspective correction and cropping?

Scandroid delegates all image processing to the Google ML Kit Document Scanner API, which automatically detects document edges, corrects perspective distortion, and applies smart cropping. The result is a flat, straight scan even when the original photo was taken at an angle.
