Privacy Policy — ScanLocker

App: ScanLocker • Package: com.scanlocker.app • Developer: ProDev Infotech • Effective: October 14, 2026 • Version 1.0.0

1. Overview

ScanLocker is a document scanner app that captures documents, enhances images, creates PDFs, extracts text with OCR, recognizes business cards and ID cards, and protects files with passwords and app lock. Everything runs locally on your device. No accounts, no cloud database, no analytics SDKs, no ads SDKs, no servers.

2. Data We Do NOT Collect or Share

We do not collect, store on servers, or share any of Google Play's data types: location, personal info, financial info, health, messages, photos, audio, contacts, app activity off-device, or device identifiers. All processing below stays on your device.

No third-party sharing: your scans and passwords are never sold, rented, or sent to brokers, advertisers, or analytics providers.
No cloud sync: scanned files, names, OCR text, app-lock state, and PDF passwords stay on the device.
User-directed sharing only: a file leaves the device only when you explicitly tap Share and choose another app through Android/iOS share sheet.

3. Permissions — On-Device Use Only

Camera

Purpose: capture documents, ID cards, receipts, and business cards for scanning. Used on-device only and never uploaded.

Photo picker / files access

Purpose: let you import a user-selected image for scanning. Modern Android/iOS photo-picker scoping is used; we do not request broad storage access.

Internet

Purpose (if enabled): only for optional OCR/model support, opening Google Play or support pages, or update checks when you initiate them. Not used for analytics, ads, or profiling.

Contact saving

Purpose: save extracted business-card details through the system contact screen. We open the platform contact sheet with pre-filled data instead of reading your contacts list.

Note: ScanLocker does not declare ACCESSIBILITY_SERVICE, FOREGROUND_SERVICE, or MANAGE_EXTERNAL_STORAGE.

4. Local Storage & Deletion

Stored on-device: scanned PDFs/images in app-private storage (`getApplicationDocumentsDirectory()/ScanLocker`), PDF passwords in platform secure storage (iOS Keychain / Android EncryptedSharedPreferences), app-lock and settings in secure local preferences.
Encryption: PDF protection uses 256-bit AES PDF encryption. Loss of password means the encrypted PDF cannot be recovered.
Delete anytime: delete files from the in-app document library or Android/iOS Settings > Apps > ScanLocker > Storage > Clear Storage / uninstall. All local data, passwords, and settings are removed permanently. There is no server copy because we have no accounts/servers.
Retention: data remains until you delete or uninstall. No automatic cloud backups.

5. Children

ScanLocker collects no data from anyone, including children under 13. Target audience is 13+. The app contains only general-audience document scanning tools with no chat, no user-generated content, and an Everyone content rating.

6. Changes

Material changes will update the Effective date above and be noted in Play release notes. Continued use after an update means acceptance.
