Privacy Policy for FastDocscan

**Last Updated:** October 2026

FastDocscan ("we", "us", or "our") is dedicated to protecting your privacy. This Privacy Policy outlines how your information is handled when you use the FastDocscan Android mobile application.

FastDocscan is built with a strict "Offline-First & Privacy-First" architecture. All core document operations—from document scanning, cropping, and OCR text extraction to PDF generation—occur completely locally on your device.

1. Permissions & Access Control

1.1 Camera Access (`android.permission.CAMERA`)

FastDocscan requires access to your device's Camera solely to scan and capture physical documents. Camera frames and captures are processed in real-time in memory. We never stream, store, or upload camera previews or photos to any external servers.

1.2 Storage & Media Access (Scoped Storage)

In alignment with modern Android best practices, FastDocscan does not require intrusive full storage permissions (`READ/WRITE_EXTERNAL_STORAGE`).

- We utilize Android's Scoped Storage and MediaStore APIs to export and save documents directly to your local offline "Downloads" folder on your internal storage.

- The app only accesses its own isolated internal sandbox directory to store draft pages, edits, and cached files.

2. 100% Offline Local Processing

2.1 On-Device Document & Text Recognition (OCR)

All text recognition (OCR) and document identification (such as ID cards, business cards, invoices, receipts, and academic certificates) are powered by local on-device machine learning models (Google ML Kit). No image data or extracted text is transmitted over the internet for processing.

2.2 Image Filtering & Enhancements

All filters—including Magic Color, Black & White, Grayscale, sharpening (HD Mode), shadow removal, and contrast enhancement—are calculated directly on your device CPU/GPU.

2.3 Local Overlay & Redaction Management

Any annotations or edits you make—such as digital signatures, text overlays, watermarks, and paint-based redactions—are saved strictly inside your local database. They never leave your device.

---

3. Security of Saved Data

3.1 Secure Local Directories & Vault

All project data, scanned pages, and vault files are stored securely within the app's private sandboxed directory (`/data/user/0/com.fastdocscan.app/`). This folder is strictly isolated and inaccessible to other applications installed on your device.

3.2 On-Device PDF Password Protection

When you protect a document with a password, the PDF is encrypted using industry-standard 128-bit AES encryption directly on your device. Your passwords are never logged, stored, or transmitted off-device.
