Privacy Policy

Scannax – PDF Scanner & OCR · Last updated: 11 October 2026

This policy explains what data the Scannax mobile app ("Scannax", "the app", "we") handles and why. In short: your documents stay on your device. Scannax has no user accounts and no servers of its own, and we never receive your documents, photos or the text in them. The app is free and shows ads from Google AdMob; the ads are the only part of the app that uses the internet.

1. Your documents and scans

• Everything you scan, import, edit, sign or recognise is processed and stored only on your device, inside the app's private storage.
• Text recognition (OCR), page detection, image enhancement and PDF creation all run on your device. Your documents are never uploaded to us or to anyone else.
• Your documents leave your device only when you choose to: for example when you tap Share, Save to device, Save to Gallery, Print or Back up. Where they go is up to you.
• Android's automatic cloud backup is turned off for Scannax, so your documents are not copied to your Google account. Scannax's own backup creates a file that you save where you choose, optionally protected with a password.
• The optional private vault encrypts documents on your device. The encryption key stays in your device's secure storage.

2. Permissions

• Camera – to scan documents. Used only while you are scanning.
• Photos and files – only the images or PDFs you pick are opened, through your phone's own picker.
• Save to Gallery – on Android 10 and older, storage permission is used only to save pages you choose into a "Scannax" album.
• Fingerprint or face unlock – only if you turn on App lock. Your biometric data is handled by your phone and is never available to Scannax.
• Internet – used by the advertising SDK (see below). Scannax does not use it to send your documents.

3. Advertising (Google AdMob)

Scannax shows ads provided by Google AdMob. To show and measure ads, the Google Mobile Ads SDK may collect and share, under Google's own policies:

• Device identifiers such as the advertising ID,
• Approximate location derived from your IP address,
• App interactions with ads, and diagnostic and performance data.

This data is used for advertising, analytics and fraud prevention, and is encrypted in transit. It does not include your documents or their content.

Where the law requires it (for example in the European Economic Area, the United Kingdom and some US states), Scannax asks for your consent before any ad is requested, using Google's consent form. You can change your choice at any time in the app under Settings › Ad privacy choices. You can also reset or delete your advertising ID in your phone's settings.

4. Google services on your device

Text recognition uses Google ML Kit, which runs on your device. The optional "Smart Scan" mode uses the document scanner built into Google Play services. These Google components may send Google limited, anonymous usage and diagnostic information under the Google Privacy Policy; they do not send your documents or recognised text.

5. Data we collect

We, the developer of Scannax, do not collect, store or sell any personal data. We have no account system, analytics service or server that receives information from the app.

6. Data retention and deletion

Your documents remain on your device until you delete them. Deleted documents go to Recently deleted and are removed permanently after the period set in the app, or straight away if you empty it. Uninstalling Scannax removes all of its data from your device, so make a backup first if you want to keep your documents.

7. Children

Scannax is a general productivity app and is not directed at children under 13. We do not knowingly collect personal information from children.

8. Security

Your documents are kept in the app's private storage, which other apps cannot read. You can add App lock, screenshot blocking, password-protected PDFs, an encrypted vault and password-protected backups for extra protection.

9. Changes to this policy

If this policy changes, the updated version will be posted on this page with a new "Last updated" date.
