Privacy Policy

1. Information We Do NOT Collect

Unlike traditional web services that process inputs on a remote backend, My GST Calc is designed as a zero-knowledge tax utility. Specifically, we never collect, transmit, or retain:

• Invoice values, turnover figures, or profit calculations.
• Goods and Services Tax Identification Numbers (GSTINs) entered for structure validation.
• Harmonized System of Nomenclature (HSN) or Service Accounting Code (SAC) search history.
• Customer names, billing details, or WhatsApp share summaries.
• Tax liability breakdowns (CGST, SGST, IGST, UTGST, RCM, or TDS amounts).

2. Browser Storage & Local Preferences

We use your web browser's native localStorage strictly for functional interface preferences:

• Theme Preference: Storing whether you selected Light Mode or Dark Mode so your choice persists across page visits.
• Recent Calculator Cache (Local): Temporary in-memory caching in your browser to maintain your form state during your active browsing session. This data is not uploaded anywhere and can be cleared at any time by clearing your browser cache.

3. Web Analytics & Server Logs

To ensure platform reliability, fast load times, and security, our web hosting provider automatically collects standard, non-personally identifiable technical diagnostic logs when you visit our website:

• Internet Protocol (IP) address (anonymized/truncated for geographical country/city routing).
• Browser type, operating system, and device screen resolution.
• Referrer URL and timestamps of page requests.

These logs are aggregated purely for performance optimization and defending against malicious denial-of-service (DDoS) attempts. They are never linked to individual tax calculations.

4. Third-Party Links & Government Portals

Our platform includes informational outbound links to official Indian Government taxation and filing portals, such as:

• GST Common Portal (gst.gov.in)
• CBIC Portal (cbic-gst.gov.in)
• E-Way Bill System (ewaybillgst.gov.in)
• E-Invoice System (einvoice1.gst.gov.in)

Please note that once you navigate away from My GST Calc via these external links, their respective privacy policies and terms of service govern your browsing session.

5. Data Security

We employ modern Transport Layer Security (TLS 1.3 / HTTPS) with automatic HSTS across all pages on mygstcalc.in. This guarantees that all communication between your browser and our content delivery network is securely encrypted.

6. Updates to This Policy

We may occasionally update this Privacy Policy to reflect changes in our tools, browser capabilities, or relevant legal regulations in India. Any revisions will be published on this page with an updated "Effective Date".
