Scanning — Privacy Policy

Effective date: November 12, 2026

In short

Scanning — Smart Doc Scanner (bundle ID az.scanning.app) does not require an account and does not store your documents in the cloud. Scans, signatures and settings stay on your device. Cropping, filters, book-page flattening, text recognition and PDF creation all run on the device. The free version may show banner ads from Google AdMob. Purchases go through the App Store or Google Play. The developer does not receive your payment details or the contents of your documents.

Documents, photos and the camera

The app uses the camera only when you scan a document, an ID or passport, a business card, or a barcode or QR code. It accesses your photos only when you choose them yourself in the system picker, to import pages or to scan a code from an image. Edge detection, cropping, filters, book-page flattening, signatures and PDF files are processed entirely on your device. Your pages are not uploaded to the developer.

Text recognition (OCR)

Text recognition runs on your device: on Android with Google ML Kit (the Latin model is included in the app; Chinese and Korean models may be downloaded to the device by Google Play services) and, when needed, Tesseract; on iPhone with Apple Vision and, if available on that device, Tesseract. Your page images are not sent to the developer.

If you recognise a script that needs a Tesseract language file (for example Russian, Ukrainian, Greek, Hebrew or Arabic), the app can download a small model file (about 1–8 MB) once from the official Tesseract tessdata_fast repository on GitHub, into the app’s private folder. GitHub, like any website, sees your device’s IP address. The document itself is not uploaded. Recognised text can be stored with the document on your device (for example to make a searchable PDF).

Business cards and contacts

When you scan a business card, the app recognises the text on your device and shows you a form to check. Only if you choose to save does the app ask for permission and create a new contact in your phone’s address book. The app does not send your contacts anywhere.

Face ID, Touch ID, fingerprint and signatures

The optional app lock and signature protection are off by default. Unlocking is handled entirely by the operating system; the app only receives a yes/no result and never has access to your biometric data. When signature protection is on, saved signatures are encrypted on the device (AES-256-GCM), and the key is kept in the iOS Keychain or in Android storage protected by the Android Keystore. The key and the signatures do not leave the device.

If you protect a PDF with a password, the file is encrypted (AES-128). The password is not stored in the app.

Advertising

In the free version a small banner ad from Google AdMob may appear at the bottom of the Home screen and the Documents list. There are no ads on the camera, editor, scanner or other work screens. Scanning Pro has no ads.

Where the law requires it (for example in the European Union, the United Kingdom and Switzerland), the app shows Google’s consent form (User Messaging Platform, UMP) on first launch. Ads are requested only if consent allows it. You can open the form again in Settings → Privacy and ads, when it is required.

The app does not use Apple’s App Tracking Transparency (ATT) prompt. On iPhone, ads work without it and are not personalised through that mechanism.

Google AdMob may use an advertising identifier, technical device information and your IP address to deliver ads, in accordance with Google’s privacy policy. The developer does not receive the contents of your documents through ads.

Purchases

Scanning Pro (monthly, yearly or lifetime) is sold through the App Store on iPhone and through Google Play on Android. Payment is processed entirely by Apple or Google; the developer does not receive your name, payment card or other payment details. The app only checks with the store whether the purchase is active.

The app contains code that can send a purchase token or a signed receipt (not your payment details) to the developer’s server, solely to confirm with Apple or Google that the purchase is valid. This server check is not enabled in the current version of the app; no purchase token is sent to our server today.

No account and no cloud

The app does not create an account and does not have its own cloud storage. If you share a file through the system share sheet (for example to Mail, a messenger, iCloud Drive or Google Drive), that service’s own policy applies.

Data stored on your device

On your device the app stores your scans and PDFs, saved signatures, settings, barcode and QR history (up to the last 100 codes), recognised text if you use OCR, and, if you download them, Tesseract language files. You can have old scans deleted automatically after 7, 14, 30, 90, 180 or 365 days, or delete them yourself in the app.

Deleting your data

Deleting a document in the app removes it from the device. Deleting the app removes its data, including scans, settings and downloaded language files. On iPhone, iOS may keep Keychain items after the app is deleted (the signature encryption key is stored there). On Android, signatures, the encryption key and language files are excluded from device backups.

Children

The app is not directed at children under 13. It does not create accounts. The free version may show ads via Google AdMob.

Changes to this policy

If this policy changes, the updated version will be published on this page with a new effective date.
