Argus GST Billing

Privacy Policy

Last updated: 23 October 2026

Argus (website argusinvoicing.com and the Argus mobile app) is operated by B&L Softwares and Logistics ("we", "us", "Data Fiduciary"). This Privacy Notice applies to individuals in India and elsewhere who use Argus. It is intended to meet transparency expectations under Indian law, including the Digital Personal Data Protection Act, 2023 (DPDP Act), the Information Technology Act, 2000, and related rules.

1. Who this covers

Argus is a business tool. You must be at least 18 years old and authorised to bind the business whose records you enter. We do not knowingly collect personal data of children under 18. If you believe a minor has created an account, contact us to delete it.

2. Personal data we process

  • Account identifiers: name, email, authentication IDs (Firebase Auth)
  • Business profile: shop name, GSTIN, phone, address, bank/UPI details you enter
  • Books you create: invoices, parties, purchases, stock, khata, expenses, reports
  • Subscription and payment metadata (plan, expiry, Razorpay/Play references — not full card numbers)
  • Optional device inputs: camera/barcode, microphone (voice entry), files you import. On Android, voice is turned into text on your phone and audio never leaves it. On the web, “Speak the bill” uses your browser's speech service (Chrome and Edge send the audio to Google to convert it to text); Argus receives only the text.
  • App crash reports (device model, app version, error details) and security logs when cloud features are used (IP-derived signals, device labels)
  • CA portal: who you invited, when, and their read-only access
  • Users of your books: the email you invite, their name once they join, the access you give them (Billing only or Full access), and the edit log of who changed what and when

We do not require Aadhaar, biometrics, or other sensitive categories. Do not enter such data into free-text fields. We do not sell personal data or use it for advertising, and Argus has no advertising or cross-site tracking cookies. The website stores your books and sign-in in your browser so the app works.

Your customers' and suppliers' details. When you enter details about other people (for example a customer's name, phone or GSTIN), you decide why and how they are used and are the Data Fiduciary for them; we process them only on your behalf to provide Argus.

3. Purposes

We process data to:

  • Provide invoicing, books, GST summaries, sync, CA sharing, and support
  • Authenticate you, manage Business/Lifetime/trial entitlements, and prevent fraud/abuse
  • Improve reliability and security; respond to legal requests where required under Indian law

Invoice and books data are kept on your device/browser first. With the Business plan, cloud sync is on by default so your phone, the website and your CA see the same books; you can switch it off in Settings at any time (your books then stay only on that device). Sharing with a CA happens only when you invite one.

4. Processors and international transfers

We use service providers ("Data Processors") to operate Argus. Current core processors include:

  • Google Firebase / Google Cloud — authentication, Firestore database, hosting, and Cloud Functions. Production Functions currently run in us-central1 (United States). Your account and synced books may therefore be processed and stored on Google infrastructure outside India.
  • Razorpay — website subscription payments (India)
  • Google Play / RevenueCat — in-app subscription billing where enabled (may involve processing outside India)
  • Firebase Crashlytics (Google) — crash reports from the Android app
  • Resend — transactional email (support, receipts, admin alerts)
  • PostHog — usage analytics, only if you opt in (“Help improve Argus” on the consent screen or in Settings; off unless you turn it on). It receives which screens and features you use, the app version and a pseudonymous id (a hash of your account id) — never bill contents, names, phone numbers, amounts or GSTINs. May be processed outside India. Turning it off stops it at once.
  • OpenRouter and the AI model it routes to — only when you tap Ask Argus on the website; a short summary is sent, without party names unless you opt in
  • Google (browser speech) — only if you use “Speak the bill” on the website in Chrome or Edge

By creating an account or enabling cloud sync, you acknowledge these transfers. We do not claim that all Argus cloud data resides only in India. We apply encryption in transit (HTTPS/TLS) and access controls; processors apply their own security programmes.

5. Cloud sync, users of your books, and CA / accountant sharing

With cloud sync on (Business plan), your books are stored in Google Cloud Firestore, encrypted in transit and at rest by Google, and read by our servers to sync your phone and the web app. When you invite a CA, they get read-only access to those books through our CA portal until you stop sharing (Settings > Share with your CA); they see your current synced books, over an encrypted (HTTPS) connection. Only you, the users you add to your books, and the CAs you invite can see your books; our staff access them only to fix a problem you report or when the law requires.

Users of your books. When you add someone (Settings > Users), they can see and work in your synced books on the app and the website, with the access you choose:Billing only (bills, customers, stock and payments; not purchases, expenses, payroll, GST returns, profit or business settings) or Full access. Each change they make is recorded in the edit log with their name, which you can see. You can change their access or remove them at any time; your books are then taken off their devices the next time they open Argus. If you join someone else's books, that business sees the bills you make there and your name in its edit log; your own books stay set aside on your phone and come back when you leave.

6. Retention

  • Local data: until you clear it, uninstall, or wipe the browser/device store
  • Cloud account and synced books: until you delete the account, subject to backup cycles
  • Payment, tax, fraud, and dispute records: up to 8 years where needed for Indian tax, accounting, or legal compliance
  • Security / rate-limit logs: shorter operational windows
  • Records of your consent (which version of these terms you accepted or withdrew, and when): kept while your account exists and up to 8 years after, to show what was agreed
  • Edit log (who changed what in the books): kept as long as the books, and cannot be edited or cleared by users, as audit-trail rules require

7. Your rights (DPDP)

Subject to applicable law, you may:

  • Access a summary of personal data we hold about you
  • Correct inaccurate account or profile data
  • Erase account data (see deletion below), subject to legal retention
  • Withdraw consent for optional processing (e.g. turn off cloud sync; stop using Ask Argus)
  • Nominate another individual to exercise rights on your behalf in the event of death or incapacity, by emailing the Grievance Officer with clear instructions and proof as we reasonably require
  • Grievance redressal — contact details below. We acknowledge complaints within 48 hours and resolve them within 30 days.
  • Complain to the Data Protection Board of India if you are not satisfied with how we resolved your grievance (DPDP Act, section 13).

Export: use in-app/web Export. Delete: account deletion page or email support@argusinvoicing.com. We process deletion requests within 30 days where feasible.

8. Security

We use HTTPS, authentication, server-side entitlement checks for cloud sync, rate limits, and one-time, expiring CA invites with read-only access you can revoke. No method is perfect — keep strong passwords and your own backups. If a personal data breach affects you, we will inform you and the Data Protection Board of India as the DPDP Act and Rules require, with what happened, the likely impact, and the steps you can take.

9. GST / government portals

Argus helps you prepare invoices and GST-style summaries. It is not a GST Suvidha Provider (GSP) and does not file returns or generate e-invoice IRNs / e-way bills on the government network unless we later announce a licensed integration. You remain responsible for filings on the GST portal.
