Privacy Policy — Madeline Sales & Inventory

1. Information Stored on Your Device

Because Madeline is an offline POS application, your sensitive business data is kept directly on your local device storage:

• Product & Inventory Data: SKUs, barcode values, product images, cost prices, selling prices, stock quantities, minimum stock threshold alerts, and shelf location tags.
• POS Transaction History: Sales receipts, cashier shift summaries, order breakdowns, tax entries, discounts, and payment methods.
• Customer Credit Ledger & CRM: Customer phone numbers, balance dues, payment transaction logs, and customer loyalty point allocations.
• Security Settings: Encrypted 4-Digit Owner PIN for restricting access to cost prices and profit margin analytics.

2. Cloud Data Transmission & Zero Monthly Fees

Madeline does not send your store inventory, transactions, customer credit logs, or financial profit data to cloud databases or central servers. There are zero recurring monthly cloud server fees because your data remains entirely under your direct physical and digital control.

3. Database Backups & Data Portability

You maintain total ownership of your store database. Through Madeline's built-in database export tool, store owners can export and restore complete store data snapshots across devices in a single click without third-party exposure.

4. Third-Party Integrations (Thermal Printing & Messaging)

When utilizing optional features such as sending digital receipts via messaging apps, SMS, or thermal receipt printing:

• Messaging / SMS: Receipts are passed directly to your device's native messaging applications. We do not inspect or retain message contents.
• Thermal Printing: Receipt text is formatted locally and dispatched via native Bluetooth or USB drivers directly to your connected printer.

5. Data Deletion & Device Reset

You can clear all store data, inventory records, customer credit logs, and settings at any time directly within the application (Settings → Reset Database) or by clearing your device storage. For web application platform accounts or support requests, you can visit our Account Deletion Request Page.

6. Security & Owner PIN Protection

Madeline incorporates a 4-Digit Owner PIN Lock to safeguard sensitive operations—including cost prices, profit margins, and manual stock audits—from frontline cashier staff.

7. Policy Changes

We may update this Privacy Policy to reflect app enhancements or legal standards. Updates will be posted on this page with a revised "Last updated" date.
