Privacy Policy

Free Scanner (com.summeria.stockscanner)

1. Data Controller Identification

The mobile application Free Scanner (hereinafter, the “Application”) is developed and operated by Juan Rivas (JRivas.tech / Summeria), based in Spain, reachable for technical support and privacy inquiries at: juanrivas.tech@gmail.com.

2. Local-First Principle and Zero-Cloud Architecture

Free Scanner is built from the ground up on the principles of Privacy by Design and a strict 100% Local-First architecture.

The application DOES NOT collect, DOES NOT store on external servers, DOES NOT sell, and DOES NOT share with third parties any personal information, advertising IDs, product lists, inventory counts, or scanned barcodes.

✓ All data generated, scanned, or imported resides exclusively within your device's private, sandboxed internal storage.

3. Device Permissions & Technical Usage

To perform its barcode scanning and spreadsheet export capabilities, Free Scanner utilizes the following Android permissions:

📷

Camera `(android.permission.CAMERA)`

Purpose: Allows the optical viewfinder to scan 1D (EAN, UPC, Code 128, Code 39) and 2D (QR) barcodes in real time.

✓ Video frames are processed strictly in volatile memory. No still pictures or videos are ever saved to disk or transmitted.

📁

Storage & Files `(READ/WRITE_EXTERNAL_STORAGE / Documents)`

Purpose: Saves generated Excel spreadsheets (.xlsx) directly into your phone's Documents or Downloads directory, or reads your master item catalog when explicitly imported.

✓ The app only touches files you explicitly choose to create, save, or open.

📳

Haptics & Audio `(android.permission.VIBRATE)`

Purpose: Instant haptic and sound confirmation whenever a barcode is successfully registered.

🌐

Network Access `(android.permission.INTERNET)`

Purpose: Used exclusively by Google Play Billing services to verify Pro license upgrades and store updates. All barcode scanning and Excel exports work 100% offline without internet.

4. In-App Purchases & Billing

Free Scanner provides optional Pro upgrades (such as unlimited exports) processed securely through Google Play In-App Billing.

All financial transactions are handled directly and securely by Google LLC. The developer never receives, stores, or manages payment cards or banking details.

5. User Control & Data Deletion

Your personal settings (language, cooldown delay between scans, color accent) and session records are stored solely within your device's local storage.

How to erase your data:

You can delete any session or scanned inventory list directly inside the app by tapping the delete icon.
You can permanently erase all local settings and history by uninstalling the app or via Android Settings > Apps > Free Scanner > Storage > Clear data.

6. Children's Privacy (COPPA & GDPR)

Free Scanner is designed for inventory and commercial stock counting. Because it requires no user accounts and collects zero personally identifiable information, it complies fully with COPPA and GDPR regulations.

7. Contact & Modifications
