Numo Scan privacy policy
Last updated: 14 November 2026
Numo Scan is a document scanner for Android, developed and published by Novixway LLC ("Novixway", "we", "us"). This policy explains what Numo Scan does with information on your phone.
The short version: Numo Scan has no accounts, no ads, no analytics and no crash reporting. Your scans are made, stored and turned into PDFs on your phone. Numo Scan does not send your documents, their text, or anything else, to Novixway or to anyone else. A file only leaves your phone when you choose to share, save or back it up somewhere yourself.
Data kept on your phone
| Data | Why | Leaves the phone? |
|---|---|---|
| Scanned pages (images) and imported photos | to keep your documents so you can view, export and share them | No |
| Document names, folders, page order and dates | to show and organize your library | No |
| Text recognized on your pages (Pro) | to let you copy and search text and to make searchable PDFs | No |
| Settings, such as app lock and automatic text recognition | to keep the app the way you set it | No |
| Whether you bought Pro | cached so Pro works offline | No (confirmed with Google Play, see below) |
| Temporary files for sharing and exporting | created when you share or export, cleared when the app starts | No |
| Passwords you type to protect a PDF | used only to encrypt that one file with AES-256 | No, and never saved |
All of this is stored in Numo Scan's private app storage, which other apps cannot read. You can delete any document or page in the app at any time. Uninstalling Numo Scan, or clearing its storage in Android Settings, deletes all of it.
Android backup. Your scans and your library are excluded from Android's automatic cloud backup, because scanned papers are often sensitive. Only small settings may be included in a device backup that Google stores under your backup settings. To move your scans, use Settings > Back up library, which writes one .zip file to a place you pick. That file is not encrypted, so keep it somewhere you trust.
How Numo Scan reaches your photos and files
Numo Scan does not ask for permission to read your storage or your photo library. When you import photos, you pick them in the Android Photo Picker and Numo Scan can read only the photos you picked. When you save, export or back up, you choose the place with the Android system file picker.
Document scanner and text recognition (Google ML Kit)
The camera scanner is the ML Kit Document Scanner, provided by Google through Google Play services. When you tap Scan, Google's scanner screen opens, uses the camera, finds the page edges and returns the page images to Numo Scan. Numo Scan does not request camera permission itself, and the images are not sent to Novixway.
Text recognition (Pro) uses the ML Kit Text Recognition model, which is bundled inside the app and runs on your phone. Your pages and their text are not uploaded for recognition.
Google Play services and ML Kit may download updates to the scanner and may send Google limited technical information, such as device model, Android version, app package name, performance metrics and error codes, to keep these features working and improve them. This is handled by Google under the Google Privacy Policy and the ML Kit terms. Novixway does not receive this information.
App lock
If you turn on the app lock (Pro), Android asks for your fingerprint, face or screen lock. Numo Scan only learns whether the check succeeded. Your biometric data never reaches the app or Novixway.
Purchases
Numo Scan Pro is a one-time purchase handled by Google Play. Google processes the payment under its own terms and privacy policy. Numo Scan asks Google Play whether Pro was bought on your Google account and remembers the answer on your phone. Novixway does not receive your payment details.
Network
Numo Scan itself does not go online to work with your documents. The only network activity related to the app is Google Play services activity for the scanner described above, the Google Play purchase check, and the normal installs and updates handled by Google Play.
Sharing and "Open in Numo PDF"
Numo Scan never shares your data. When you tap Share, Android shows its share sheet and the file goes only to the app or person you choose. "Open in Numo PDF" hands the PDF to our Numo PDF app on the same phone, which also works offline. What another app does with a file you send it is governed by its own policy.
What we do not do
- No account or sign in.
- No ads and no advertising ID.
- No analytics, tracking or crash reporting SDKs, and no Firebase.
- No sale or transfer of your information to anyone.
Children
Numo Scan is a general purpose productivity app and is not directed at children under 13.
Changes
If this policy changes, the new version will be posted at this address with a new "Last updated" date. Material changes will also be noted in the app's release notes.
