Docsy Scanner is an Android application that scans paper documents into searchable PDFs. This policy explains what data Docsy Scanner handles, where it lives, and what control you have over it. We built Docsy Scanner with a “private by default” principle: your scans stay on your device unless you explicitly ask us to send them somewhere else.

Who runs Docsy Scanner

Docsy Scanner is developed and operated by Hiren Paghadal(“we”, “us”) as an individual developer. You can reach us at .

What data Docsy Scanner handles

1. Data stored on your device only

  • Every document you scan or import — the original image, the processed image, the OCR text, and the generated PDF — is stored inside your app’s private storage on your device. This data never leaves your device unless you explicitly enable cloud backup, sync, or share.
  • Folders, tags, watermarks, signatures, and app preferences (theme, OCR language, etc.) are stored locally in an encrypted SQLite database.
  • Passwords used to protect individual PDFs are stored in the Android Keystore on your device; we never see them.

2. Data you optionally send to Google Drive

Docsy Scanner has two optional features that use your own Google Drive:

  • Cloud backup: When you enable backup, Docsy Scanner creates a .qsbarchive of your local data, encrypts it with a passphrase you choose, and uploads the encrypted archive to Google Drive’s hidden application data folder. This folder is private to Docsy Scanner — no other app or website can access it. The passphrase never leaves your device; if you lose it, we cannot recover your backup.
  • Multi-device sync: When you enable sync, Docsy Scanner uploads an encrypted change log and copies of page images to the same private Drive folder so a second device with the same Google account can restore them.

Docsy Scanner uses the drive.appdata OAuth scope, which restricts access to this hidden folder only. We do not read, modify, or list any other files in your Google Drive. A separate read-only scope, drive.metadata.readonly, is requested only to display your Drive storage quota inside the app.

3. Data you optionally send to Google Cloud Vision

If you enable Cloud OCR to improve accuracy for a specific page or document, Docsy Scanner sends the corresponding page image to Google Cloud Vision on your explicit action. Google processes the image and returns the recognized text. We forward this request through our own Google Cloud project and delete the image from any Docsy Scanner-controlled system as soon as the response comes back; Google’s own retention terms then apply. This feature is off by default and can be disabled at any time in Settings.

4. Data handled by third-party services

  • Google Play Billing & RevenueCat: If you subscribe to Docsy Scanner Pro, your purchase is processed by Google Play. We use RevenueCat to check whether your subscription is active. RevenueCat receives your Google account identifier for the sole purpose of matching subscription state across your devices.
  • Google Sign-In: When you sign in with Google, we receive your email address and a stable user identifier so we can bind the sync + backup features to your account. We do not receive your password or contact list.

5. Data we do not collect

  • No analytics or usage tracking.
  • No advertising identifiers.
  • No location data.
  • No contact list, phone number, or SMS access.
  • No camera roll access (Docsy Scanner only reads images you explicitly pick).

Data security

  • Your on-device database is encrypted at rest with an app-specific key managed by the Android Keystore.
  • Cloud backups are encrypted with your passphrase using AES-256-GCM before upload. Google Drive stores only the encrypted bytes.
  • Password-protected PDFs use PDF-native AES-256 encryption.
  • All network traffic to Google APIs uses HTTPS/TLS.

Your rights and controls

  • Access & export: You can export any document as a PDF or copy your entire library into a .qsb archive at any time from Settings → Backup.
  • Delete: Uninstalling Docsy Scanner deletes all local data. See for step-by-step instructions to also remove Docsy Scanner’s Google Drive access and any cloud backups.
  • Revoke sync/backup: Sign out from Settings → Cloud sync (or Cloud backup) at any time. This disconnects Docsy Scanner from your Google account. Existing backups stay on your Drive until you delete them.
  • Children: Docsy Scanner is not directed at users under 13. We do not knowingly collect data from children under 13.

International transfers

Docsy Scanner operates from India. Where you send data to Google Drive or Google Cloud Vision, the data may be processed in servers operated by Google outside your country of residence. See Google’s privacy policy for details of how Google handles that data.

Changes to this policy

We may update this policy from time to time. Material changes will be announced inside the app or at this URL. Continued use of Docsy Scanner after a change means you accept the updated policy.
