Privacy Policy

Last Updated: January 1, 2025Effective: January 1, 2025App Store ID: 1659586239
This Privacy Policy applies exclusively to the PDF Scanner: Photo to PDF App published by KN Apps Studio. This is a 100% offline app. All scanned documents and PDF files are stored on your device only and are never uploaded to any server.
🔒 Privacy Summary: No internet required. No cloud uploads. No account needed. All data stays on your device. OCR processing is entirely on-device.

1. About This App

PDF Scanner is a fully offline iPhone app. All features — camera scanning, OCR text extraction, PDF creation, editing, and file management — work entirely without an internet connection. No data is ever transmitted to KN Apps Studio servers or any external service during normal app use.

2. Data We Collect

Because this app is offline, data collection is minimal and limited to:

  • Usage Data — how you interact with app features and session information, used for analytics and app improvement.
  • Device Identifier — a non-personal Device ID used for advertising (in the free version) and analytics only. Does not include your name or email.
  • Coarse Location — approximate city/region level, used for analytics and to serve relevant ads. No precise GPS collected.
  • Crash & Diagnostics Data — used solely to identify bugs and improve stability.
  • Advertising Data — ad interaction data in the free version to measure ad effectiveness.

3. Data We Do NOT Collect

KN Apps Studio does not collect, store or access:

  • Any scanned documents or images you capture with the camera
  • Any PDF files created, edited or stored in the app
  • Any OCR-extracted text from your documents
  • Your name, email address or any personal identity
  • Any file content from your device storage

4. On-Device Storage

All scanned documents, PDFs, app settings, and user data are stored exclusively on your iPhone or iPad using Apple's local storage APIs. This data never leaves your device. KN Apps Studio has no access to your files.

5. OCR Processing

Text extraction (OCR) is performed entirely on-device using iOS's built-in Vision framework. No text content from your documents is sent to any external server. The OCR process is local, private, and does not require an internet connection.

6. Third-Party Advertising (Free Version)

The free version of the app displays advertisements via Google AdMob. AdMob may collect Device ID and coarse location to serve relevant ads. These services operate under Google's Privacy Policy. The premium (paid) version is ad-free.

7. Analytics

We use Firebase Analytics for crash reporting and general usage analytics. This service collects anonymised usage statistics and crash logs only. No document content is included.

8. Your Rights (GDPR / CCPA)

You have the right to access, correct or delete your data, and to opt out of targeted advertising via iOS Settings → Privacy & Security → Tracking. Contact us at help@knappsstudio.com to exercise these rights.

9. Children's Privacy

This app is rated 4+ and is not directed at children under 13. We do not knowingly collect personal data from children.

10. Data Retention

Analytics and crash data are retained for up to 12 months. Your on-device files are under your full control — delete them at any time from within the app or iOS Settings.

11. Changes to This Policy

We may update this policy periodically. Continued use after changes indicates acceptance of the updated policy.
