Privacy Policy for PDF Reader - Editor & Viewer

 

At ByteWhales ("we," "our," or "us"), we respect your privacy and are committed to protecting your personal information. This Privacy Policy explains how we handle information when you use our mobile application, PDF Reader - Editor & Viewer (the "App"), available on iOS and Android.

Please read this Privacy Policy carefully. By downloading, accessing, or using the App, you agree to the collection and use of information in accordance with this policy.

1. Summary of Key Principles

  • Local Processing First: All your PDF reading, editing, annotations, digital signatures, page modifications, and scans are processed 100% locally on your device.

  • No Mandatory Account: You can use all core features without registering, creating an account, or logging in.

  • No File Uploads: We do not upload, read, store, or monitor your private PDF files, documents, or scanned images on our servers.

  • Zero Sale of Data: We never sell, rent, or trade your personal information or document contents to any third party.

2. Information We Collect and Process

A. Document Data & Local Storage

  • PDF Files & Documents: When you open, view, edit, sign, merge, split, compress, or scan documents, these files remain securely in your local device storage or the app's sandboxed storage directory. We do not transmit or upload your documents to external cloud servers.

  • Signatures & Annotations: Any signatures, drawings, stamps, notes, or form fills you create are saved directly into your local document and stored only on your device.

  • User Preferences: Local preferences (such as theme mode, reading orientation, favorite files, and recent documents list) are saved locally on your device using Hive local storage.

B. Device Information & Diagnostics (Automatically Collected)

To ensure app performance, reliability, and stability, we automatically collect non-personal diagnostic and technical data through third-party SDKs:

  • Device Characteristics: Device model, operating system version (iOS/Android), system language, screen resolution, and available storage space.

  • Diagnostic & Crash Logs: Crash stack traces, memory statistics, and error logs collected via Firebase Crashlytics to diagnose bugs and prevent crashes.

  • Aggregated Usage Metrics: Anonymous usage metrics (such as feature interaction frequency and session duration) collected via Firebase Analytics to optimize app performance.

C. Customer Support Inquiries

If you voluntarily contact us via email for customer support or feedback, we collect your email address and any details you provide in your message solely to respond to your inquiry and resolve technical issues.

3. Device Permissions We Request

The App requests the following device permissions only when necessary for specific features:

Camera (NSCameraUsageDescription / android.permission.CAMERA)

Purpose: Required when you use the built-in Document Scanner to capture pages, receipts, notes, and photos to convert them into PDF files.

Privacy: Camera feeds are processed locally in real time and are never recorded, streamed, or uploaded.

Photo Library / Storage (NSPhotoLibraryUsageDescription / Storage Permissions)

Purpose: Required to import existing photos for image-to-PDF conversion or to save exported PDF pages and images to your device photo gallery.

Privacy: Only the specific files you select are accessed.

Notifications (android.permission.POST_NOTIFICATIONS / iOS Notifications)

Purpose: Used to notify you when batch file conversions, compression tasks, or downloads complete. You can disable notifications at any time through your device settings.

App Tracking Transparency (NSUserTrackingUsageDescription on iOS)

Purpose: With your explicit permission, used by Google AdMob to deliver personalized ads and measure advertising campaign effectiveness. If permission is declined, non-personalized ads may be displayed.

4. Third-Party Service Providers

We integrate trusted third-party SDKs that may collect information used to identify your device in accordance with their respective privacy policies.

Google AdMob (Google LLC)

Used to serve in-app banner, interstitial, and native advertisements that support free features.

Privacy Policy: https://policies.google.com/technologies/ads

Firebase (Google LLC - Analytics, Crashlytics & Realtime Database)

Used to monitor application performance, record crash diagnostics, and securely load remote ad or app configurations.

Privacy Policy: https://policies.google.com/privacy

In-App Purchases (Apple StoreKit & Google Play Billing)

If you purchase a premium upgrade or subscription, payment processing is handled exclusively by Apple (App Store) or Google (Google Play). We do not collect or store your credit card or financial details.

5. Data Retention & Deletion

  • Local Document Control: You have full control over your documents. You can delete documents, clear recent file history, or empty the Recycle Bin at any time from within the App.

  • App Uninstallation: Deleting the App will remove all sandboxed files and local preferences stored on your device.

  • Analytics Data: Anonymous analytics and crash logs collected by Firebase are retained in accordance with Google's data retention policies.

6. Security of Your Data

We prioritize the security of your documents and information. Because your documents are stored and processed locally on your device, their security is protected by your operating system's built-in sandbox, encryption, and biometric authentication (Face ID, Fingerprint, or Passcode where supported).

All network communications with third-party service providers, including AdMob and Firebase, use industry-standard TLS/HTTPS encryption.

7. Children's Privacy

PDF Reader - Editor & Viewer does not knowingly collect, solicit, or maintain personally identifiable information from children under the age of 13 (or under 16 in certain jurisdictions). If we become aware that personal information from a child has been collected, we will take appropriate steps to delete such information.

8. Your Rights (GDPR, UK GDPR, and CCPA / CPRA)

Depending on your geographic location, you may have statutory rights regarding your personal information, including:

  • Right to Access and Portability: Request confirmation of whether we process your personal data.

  • Right to Erasure: Request deletion of personal data we may hold, such as support communications.

  • Right to Opt Out of Tracking: You can opt out of personalized advertising and tracking through your device settings.

iOS: Settings → Privacy & Security → Tracking

Android: Settings → Google → Ads → Delete Advertising ID or Opt Out of Ads Personalization
