Privacy Policy

1. PDF Processing & Local Security

Your privacy is extremely important to us. Drut PDF operates as an on-device utility suite designed for local document management.

2. Local Application Storage & Data Controls

All app settings, tool preferences, bookmarks, and local application states are stored strictly within your device's private sandbox storage.

• No Remote Document Storage: We do not host or store any of your document content or user profiles on cloud databases.
• Data Deletion Instructions: You can completely erase all local application data at any time by navigating to Settings > Apps > Drut PDF > Storage > Clear Data on your Android device, or by uninstalling the application.

3. Device Storage & File Permissions

Drut PDF requests storage or file access permissions solely to enable core features requested directly by you—such as opening, editing, saving, and managing PDF files on your device's internal storage.

These permissions are strictly utilized for user-initiated file operations and are never used to access unrelated media or personal content.

4. Third-Party Services (Firebase & Google AdMob)

To ensure application stability, diagnose crashes, evaluate usage trends, and support ongoing development through advertising, Drut PDF integrates trusted third-party SDKs provided by Google:

A. Google Analytics for Firebase

• Data Collected: App-instance IDs, device model, operating system version, screen views, session duration, and user interaction events.
• Purpose: To understand feature usage patterns and optimize app performance.

B. Firebase Crashlytics

• Data Collected: Crash logs, stack traces, memory state, and device diagnostic information at the time of an app crash or ANR (Application Not Responding).
• Purpose: To identify, debug, and resolve stability and performance issues across different device models.

C. Google AdMob (Advertising)

• Data Collected: Android Advertising ID (AAID), IP address, approximate coarse location (country/city level), device specifications, and ad interaction metrics.
• Purpose: To serve contextual or personalized advertisements and prevent ad fraud.

For more details on how Google handles collected diagnostic and analytics data, please review the Google Privacy & Terms Policy.

5. Data Security & Encryption in Transit

All diagnostic metrics, crash reports, and advertising tokens sent to third-party services (Firebase and Google AdMob) are encrypted in transit using industry-standard HTTPS/TLS encryption protocols.

6. Managing Privacy Preferences & Ad Opt-Out

You have full control over interest-based advertising on your device. You can view, reset, or opt out of personalized ad targeting at any time via your Android device settings:

7. Children's Privacy (COPPA & GDPR Compliance)

Drut PDF is a productivity tool intended for students, professionals, and general audiences aged 13 and older. We do not knowingly collect personal information from or direct targeted advertising to children under the age of 13 (or under 16 in the EU/UK).

If you believe a child has provided information through our application or third-party SDKs, please contact us immediately so we can take appropriate corrective steps.

8. Changes to This Privacy Policy

We may update our Privacy Policy periodically to reflect app functional enhancements or store compliance policy updates. Any updates will be published directly on this page with a revised "Last Updated" date at the top.
