Privacy Policy

Last updated: 11 October 2026

This Privacy Policy explains how D Printers ("we") collects, uses and protects personal data when you use GST Billing Pro. We process personal data in accordance with the Digital Personal Data Protection Act, 2023 and the Information Technology Act, 2000 and rules made under them.

1. Data we collect

• Account data: your email address and a securely hashed password (or your Google sign-in identity if you choose "Continue with Google").
• Business data you enter: business name, address, GSTIN, PAN, bank/UPI details, logo, and your invoices, customers (including their names, phone numbers, addresses and GSTINs), products, expenses and purchases.
• Payment data: plan, amount, date, and Razorpay order and payment IDs. Card, UPI and bank credentials are collected and processed by Razorpay, not by us.
• Technical data: basic logs (IP address, browser type, time of request) kept by our hosting providers for security and troubleshooting.

2. Why we use it

• To provide the Service: store your data, generate invoices and reports, and sync across your devices.
• To manage your trial and subscription and to verify payments.
• To give support when you contact us, and to send important service messages (security, billing, policy changes).
• To keep the Service secure and prevent fraud or abuse.

We do not sell your data, and we do not use your customers' details for our own marketing.

3. Who we share it with

Only with service providers who help us run the Service, under contracts that require them to protect it:

• Supabase — database, authentication and file storage.
• Cloudflare — website hosting, content delivery and server functions.
• Razorpay — payment processing.
• Google — only if you use Google sign-in or choose to back up to your own Google Drive.

We may also disclose data where required by law, a court order or a government authority. When you share an invoice by WhatsApp or email, it goes from your device through the app you choose.

4. Storage and security

Data is encrypted in transit (HTTPS) and stored with our providers, which may be located outside India. Each account's data is isolated with database row-level security so that one customer cannot read another's data. No system is perfectly secure; please use a strong password and sign out on shared computers.

5. Retention

We keep your data while your account is active. If you ask us to delete your account we will delete your personal and business data within 30 days, except records we must keep by law (for example payment records for tax purposes, usually 8 years).

6. Your rights

You may access, correct, export or erase your personal data, withdraw consent, and nominate another person to exercise these rights. Most data can be edited or exported directly in the app; for anything else write to support@gstbillingpro.com. If you are not satisfied with our response you may approach the Data Protection Board of India.

7. Cookies and local storage

We use browser local storage to keep you signed in and to remember app preferences. We do not use advertising or cross-site tracking cookies.

8. Children

The Service is meant for businesses and is not directed at children under 18.

9. Changes

We will post changes to this policy on this page and, for significant changes, notify you in the app or by email.
