Privacy Policy

M-Square Technologies ("we", "us" or "our") provides GST Invoice Maker: M-Square (the "App"), an Android application for creating GST invoices, previewing PDFs and sharing them through compatible applications. This policy explains how the App handles information.

1. Information you enter

The App processes information you choose to provide for its invoicing features, including:

• Business details: company name, description, address, phone number, email address, website, GSTIN, PAN and a company logo.
• Optional payment details: account holder name, bank name, branch, account number, IFSC, UPI ID and UPI payee name.
• Invoice settings: invoice number prefix, postfix, digit count, last used serial number and terms and conditions.
• Invoice contents: customer name, address and optional GSTIN; invoice number and date; place of supply; item or service descriptions; HSN/SAC codes; quantities, units, rates, tax percentages and calculated totals.

No user account or login is required. Please enter other people's information only when you are authorised to use it for the invoice.

2. How information is used

Information is used to personalise invoices, calculate amounts from the values you enter, format invoice numbers, generate and preview PDFs, include optional bank and UPI payment details, and share documents at your request. A saved company logo may also be displayed on the App's splash screen.

When you provide a UPI ID, the App may encode that ID, the payee name, invoice amount and invoice reference in a payment QR code included in the PDF. Anyone with that PDF may be able to read this information or scan the QR code. The App does not request your UPI PIN, bank login credentials or card details, and does not process, verify or monitor payment transactions.

3. Local storage and invoice files

Your business profile, optional payment details, terms and invoice numbering preferences are saved locally in the App's device storage. A selected logo is copied to the App's local storage so it can be reused.

The App does not maintain a searchable invoice history or a cloud invoice database. Current invoice details are used while you create and preview the document. PDF preview and sharing components may create temporary or cached files on your device; these may remain until the App or operating system removes them.

PDFs you export, download, send or save outside the App can remain in other applications, storage locations or recipients' devices. The App does not automatically delete those copies.

Depending on your Android device, system settings and backup provider, Android backup or device-transfer services may back up or restore some App data. We do not operate or control those system services.

4. Collection by M-Square Technologies

We do not operate an App backend that receives your company profile, logo, bank details, invoice contents or saved numbering settings. We do not sell or rent that information.

The current version does not include advertising, advertising identifiers, analytics tracking, social login or cloud synchronisation. Technical libraries are used for local storage, image selection, PDF generation, PDF viewing and document sharing.

5. Sharing and third-party applications

When you choose Share, the App makes the selected PDF available to the application you choose, such as WhatsApp or an email application. The document can contain your business, customer, tax and payment information. Sharing is initiated by you; the App does not automatically send invoices to recipients.

Once a document is shared, its handling is governed by the receiving application's privacy policy and your recipient's actions. We do not control third-party messaging, email, cloud storage, bank or UPI applications.

6. Photo access and device permissions

The App uses Android's image-selection facilities to let you choose a company logo. Depending on your Android version, Android may present a system picker or request permission. The App uses the image you select for branding; it does not scan your gallery for advertising or upload your photo library to our servers.

The App does not require access to your contacts, SMS messages, call logs, microphone or precise location for its invoicing features. You can manage permissions through Android Settings. Document sharing uses the platform's sharing facilities.

7. Retention, editing and deletion

• You can change your saved business and payment information in Company Profile, and remove the selected logo there.
• You can change numbering preferences in Invoice Numbering settings.
• Starting a new invoice clears the current invoice form; it does not remove PDFs already exported or shared, or necessarily clear temporary sharing files.
• To remove locally saved App data, use Android Settings > Apps > GST Invoice > Storage > Clear storage/data. Menu names vary by device.
• Uninstalling normally removes the App's private local data. Separately saved files, recipient copies and system backups may remain. Manage those through the relevant application, storage location or backup settings.

We cannot remotely view, recover or delete information stored only on your device. There is no App account to delete.

8. Security

Local information is stored within the App's storage area and is subject to Android's access protections and your device security. The App does not provide an additional app-level encryption or password-lock feature. Protect your device with a screen lock and review invoice contents before sharing. No storage or sharing method can be guaranteed completely secure.

9. Support and this policy website

If you contact us, we receive the email address and information you include in your message and use it to respond and resolve your request. Do not send bank passwords, UPI PINs or other authentication secrets.

Opening this policy in a browser may result in ordinary website connection logs, such as an IP address, browser information and request time, being processed by the website hosting provider. This is separate from the App's local invoice processing. This policy page itself does not include advertising or analytics scripts.

10. Children's privacy

The App is intended for business and professional use and is not directed at children under 13. We do not knowingly collect children's personal information through an App backend. If you believe a child has sent personal information to us through a support message, contact us so we can address it.

11. Changes to this policy

We may update this policy when the App's features or information-handling practices change. The updated policy will be published on this page with a revised date. Where appropriate or required, we will also provide notice within the App. New advertising, analytics, account or cloud features, if introduced, will require corresponding privacy disclosures.
