Privacy Policy

  Last Updated: 27 July 2026

This Privacy Policy describes how Smple Billing ("the App," "we," "us," or "our") collects, uses, stores, and protects information when you use our mobile application and related services. This policy applies to all users of the App, including business owners ("Merchants") who use the App to manage billing operations, and any information about their customers that Merchants may enter into the App.

By downloading, installing, or using Smple Billing, you agree to the terms of this Privacy Policy.

1. Information We Collect

1.1 Account Information

When you register for an account, we collect:

• Username and password (stored securely using industry-standard hashing; we never store your password in plain text)
• Business/shop name, address, and contact phone number
• GSTIN (Goods and Services Tax Identification Number), if provided
• UPI ID, if provided, for payment collection purposes

1.2 Customer Data (Entered by Merchants)

Merchants using the App may enter information about their own customers, including:

• Customer names and phone numbers
• Purchase history, billing amounts, and payment records
• Outstanding credit balances and payment history

Merchants are responsible for obtaining appropriate consent from their customers before entering this information into the App, in accordance with applicable local laws.

1.3 Billing and Transaction Data

We collect and store:

• Item and category details entered by the Merchant
• Bill/invoice records, including itemized purchases, quantities, prices, discounts, and applicable taxes (GST)
• Payment method used for each transaction (Cash, UPI, or Credit)
• Timestamps of all transactions

1.4 Device and Usage Information

• Device identifiers, used solely to support offline functionality and data synchronization across a Merchant's devices
• App usage logs, used for debugging and improving app stability

1.5 Bluetooth Printer Information

The App uses Bluetooth to connect to thermal receipt printers. We access:

• A list of nearby Bluetooth devices (required by Android to identify and connect to printers)
• The MAC address of the specific printer(s) you choose to pair with the App

We do not use Bluetooth data for any purpose other than connecting to and printing receipts on your chosen printer. Android requires location permission alongside Bluetooth scanning on certain OS versions; we do not use this permission to track your physical location, and no location data is transmitted to or stored on our servers.

1.6 WhatsApp Messaging (Optional Feature)

If a Merchant chooses to use the WhatsApp sharing feature to send a receipt or payment reminder to a customer, the App will open WhatsApp with a pre-filled message containing the relevant bill details (items, amount, customer name). This message is sent directly through WhatsApp using the customer's phone number entered by the Merchant; we do not access, read, or store any WhatsApp messages, contacts, or chat history.

2. How We Use Your Information

We use the information described above to:

• Provide, operate, and maintain the App's core billing, inventory, and customer management functionality
• Synchronize data across multiple devices used by the same Merchant account
• Generate reports and analytics for the Merchant's own business (e.g., sales totals, outstanding credit summaries)
• Enable printing of physical receipts via connected Bluetooth printers
• Facilitate optional communication with customers via WhatsApp, at the Merchant's initiation
• Maintain and improve the security, stability, and performance of the App
• Respond to support requests

We do not sell, rent, or trade any personal information to third parties for marketing or advertising purposes.

3. Data Storage and Security

• All account, billing, and customer data is stored securely using Supabase, a hosted database provider, with industry-standard encryption in transit (HTTPS/TLS)
• Passwords are hashed and never stored or transmitted in plain text
• Authentication tokens are stored securely on your device using platform-appropriate secure storage mechanisms and are never written to unencrypted local storage
• Some data is also cached locally on your device (in a local database) to support offline use. This local data is cleared automatically when you log out of the App
• We implement tenant-level data isolation, meaning each Merchant's business data (bills, customers, settings) is strictly separated from other Merchants using the App and cannot be accessed by other accounts

4. Data Sharing and Third-Party Services

We use the following third-party service providers to operate the App:

These providers process data on our behalf and are contractually and technically restricted from using it for their own purposes. We do not share your data with any other third party except:

• When required by law, regulation, legal process, or governmental request
• To protect the rights, property, or safety of our users or the public
• With your explicit consent

5. Data Retention

We retain your account and business data for as long as your account remains active. If you wish to delete your account and associated data, please contact us using the details below, and we will process your request in accordance with applicable law.

6. Your Rights and Choices

Depending on your location, you may have rights to:

• Access the personal data we hold about you
• Request correction of inaccurate data
• Request deletion of your account and associated data
• Withdraw consent for optional features (e.g., WhatsApp sharing) at any time by simply not using them

To exercise any of these rights, please contact us using the information below.

7. Children's Privacy

Smple Billing is a business tool intended for use by adult business owners and their staff. We do not knowingly collect personal information from children under 18. If we become aware that a child has provided us with personal information, we will take steps to delete such information.

8. Permissions Used by the App

We only request permissions that are directly necessary for the App's functionality. We do not request or use permissions unrelated to these purposes.

9. Changes to This Privacy Policy

We may update this Privacy Policy from time to time to reflect changes in our practices, technology, or legal requirements. We will post the updated policy on this page with a revised "Last Updated" date. Continued use of the App after any changes constitutes acceptance of the updated policy.
