2. Data Storage & Security

2.1 Local Storage

All application data is stored locally on your device using an encrypted SQLite database. This means:

• Your data remains on your device at all times during normal use.
• No internet connection is required for core functionality (sales, inventory, reports).
• If the app is uninstalled or the device is lost, data may be lost unless you have performed a backup.

2.2 Optional Cloud Backup (Google Drive)

DukaMax offers an optional cloud backup feature that, when activated by you, allows you to:

• Sync business data (sales, products, customers) to your personal Google Sheets account.
• Upload a complete database backup file to your personal Google Drive.

2.3 SMS Permissions

DukaMax may request permission to send SMS messages for the following purposes:

• Receipt SMS: Sending sale confirmation messages to customers after a purchase (only when you explicitly enable this feature during checkout).
• Report SMS: Sending daily sales reports to a designated phone number (e.g., business owner's phone).

SMS messages are sent directly from your device. We do not intercept, store, or access the content of these messages. SMS sending is always initiated by your explicit action.

3. Data Ownership & Your Rights

You have full ownership and control over all data within the DukaMax application:

• Access: You can view all your data at any time within the app.
• Modification: You can edit, update, or correct any information stored in the app.
• Deletion: You can delete individual records (products, customers, transactions) or clear all data by uninstalling the app.
• Export: You can export your data as PDF reports or sync to Google Sheets.
• Backup & Restore: You can create and restore backups at any time using the Cloud Backup feature.

4. Third-Party Services

DukaMax integrates with the following third-party services, only when you explicitly enable them:

• Google Sign-In & Google Drive API: Used for optional cloud backup functionality. Subject to Google's Privacy Policy.
• Google Sheets API: Used for optional data sync. Subject to Google's Privacy Policy.

We do not integrate with any advertising networks, analytics platforms, or data brokers.

5. Children's Privacy

DukaMax is a business management application intended for use by adults. We do not knowingly collect data from children under the age of 13. If you believe a child has used the app, please contact us and we will assist with any concerns.
