🛡️ Core Commitment: 100% Local-First Privacy
Your PDF files, scanned camera images, digital signatures, and biometric vault records remain strictly on your physical Android device. We do NOT transmit your documents to external cloud AI servers, nor do we use your data to train AI models.
1. Introduction
This Privacy Policy explains how AI PDF & Doc Tool ("the App", "we", "us", or "our") collects, uses, and safeguards information when you use our mobile application and related web services. We are dedicated to transparent, privacy-first software development in full compliance with the Google Play Developer Program Policies, the General Data Protection Regulation (GDPR), the UK Data Protection Act, and the California Consumer Privacy Act (CCPA).
2. Information Processed by the App
A. Document Files, Images and Signatures (Processed 100% On-Device)
When you use tools such as PDF Compression, PDF Merging, Page Extraction, Watermarking, Digital Signing, or OCR Scanner:
- All document parsing, image extraction, and PDF manipulation are performed strictly in memory and local storage via native on-device libraries (iText 8, Google ML Kit).
- Your documents and images are never uploaded to any cloud server controlled by us or third parties.
- Saved files are kept in your app-private storage sandbox (
filesDir), protected by Android's Scoped Storage architecture.
B. Artificial Intelligence & Generative AI Features
Our app features generative document summarization, contextual Q&A chat, flashcard generation, and neural translation:
- On-Device Inference: Machine learning algorithms and natural language processing run directly on your smartphone hardware.
- Zero Third-Party Model Training: Your document excerpts, questions, and summaries are NEVER shared with OpenAI, Google Cloud LLM, Anthropic, or any remote AI cloud, and are never used to train machine learning models.
- In-App Feedback: Users can flag inaccurate or problematic AI outputs directly via our in-app "Report Issue" link or by emailing ai-safety@aipdf.com.
C. Biometric Vault Security
The Smart Vault allows users to store confidential documents with biometric protection (Fingerprint or Face Unlock):
- Biometric authentication is managed entirely by Android's hardware-isolated
BiometricPrompt subsystem.
- The App never receives, accesses, or transmits raw biometric identifiers.
- Vault records remain locally encrypted in the app's sandboxed storage.
D. Crash Analytics & Diagnostics (Google Firebase)
To maintain stability across Android devices, we use Google Firebase Crashlytics and Firebase Analytics:
- We collect anonymized technical crash logs (e.g., stack traces, device model, operating system version, memory state during crash).
- We collect general non-identifying telemetry (e.g., app launch frequency, screen views).
- No document names, file contents, or personal inputs are ever included in diagnostic logs.
E. Advertising & Consent (Google AdMob & UMP)
For free-tier users, Google AdMob serves advertising:
- EEA and UK Consent: In compliance with the Google EU User Consent Policy, users located in the European Economic Area (EEA) and the United Kingdom (UK) receive the certified Google User Messaging Platform (UMP) consent modal on first launch to select personalized or non-personalized ad preferences.
- Revocation / Privacy Options: Users can review, change, or revoke their consent choices at any time directly inside the app: Settings > Ad & Privacy Preferences (EEA & UK).
F. Subscriptions & In-App Purchases (Google Play Billing)
When you purchase an AI PDF Pro membership or Top-Up Credit Pack:
- Transactions are processed securely by Google Play Billing. We never collect or store your credit card or bank details.
- We receive only an encrypted Google Play purchase token and product ID to activate your Pro status.
- Subscriptions renew automatically unless cancelled at least 24 hours prior to the end of the billing period via your Google Play Account Settings.
3. How We Use Information
We use the limited technical data collected solely to:
- Deliver, execute, and maintain app utilities and tools.
- Maintain Pro subscription entitlements and credit balances.
- Diagnose crashes, fix software bugs, and optimize app performance.
- Ensure compliance with Google Play Store policies and legal regulations.
4. Data Deletion & User Rights
You have full control over your data at all times:
- Instant In-App Data Wipe: Navigate to Settings > Data Privacy & Deletion > "Delete All App Data & Reset". This permanently purges all local databases, imported files, vault records, chat histories, and cache from your device.
- External Web Deletion Portal: If you uninstalled the app or wish to request deletion of associated diagnostic telemetry or customer support emails, submit a request via our Data Deletion Portal or email privacy@aipdf.com.
5. Children's Privacy (Google Play Families Policy)
AI PDF & Doc Tool is designed for general audiences, professionals, and students (aged 18 and older, or 13+ with parental consent). We do not knowingly collect personal information from children under 13. If you believe a child has provided us with personal data, contact us at privacy@aipdf.com for immediate removal.
