Privacy policy
Effective 2026-05-26
399apps ("we", "us") helps Indian businesses run accounting, GST and inventory operations. This page explains what data we collect, why, and how it's looked after.
1. What we collect
Account details (name, email, mobile, organisation name and GSTIN), transactional data you enter (customers, vendors, invoices, payments, line items), and operational telemetry (request logs, error traces, sign-in events) used to keep the service running and secure.
2. Why we collect it
To deliver the bookkeeping, invoicing, tax-return and reporting features you signed up for; to enforce statutory record-keeping requirements under Indian GST and the Income-tax Act; and to investigate abuse, fraud and security incidents.
3. Where data lives
Customer data is hosted in AWS Asia Pacific (Mumbai / ap-south-1). Backups are encrypted and retained for 30 days. We do not sell personal data to third parties.
4. Who can see it
Only the organisation members you invite, and a small number of 399apps engineers acting under audited break-glass procedures during incident response. Accounts are authenticated in-house with encrypted passwords; payment links are routed through Razorpay; transactional email goes through Amazon SES — see those providers' own privacy notices for sub-processor detail. The sign-up and sign-in pages (before you are inside an account) send cookieless page-view and click analytics to PostHog, hosted in the US; nothing from inside your account is sent to it.
5. Your rights
You can export every record we hold about your organisation as JSON from Settings → Export data. You can permanently delete the organisation and all its records from Settings → Close organisation. Both flows are self-serve and require no support ticket.
6. AI assistants
You can connect 399apps to an AI assistant such as ChatGPT or Claude through OAuth, choosing one organisation at consent. The connection is read-only: an assistant can look things up but can never create, change or send anything in 399apps. Only the results of the tools you ask the assistant to use leave our servers — for example customer names, balances, invoice details and item stock, for the organisation you chose. We keep the connection record (assistant name, organisation, scopes and when it was last used) until you revoke it plus 30 days. We do not keep tool results or conversation text. The assistant platform stores those results in your chat history under its own privacy policy, and consumer ChatGPT may use that data for training unless you opt out in ChatGPT's settings. Under India's Digital Personal Data Protection Act 2023, the organisation's owner is responsible for consenting to this transfer of its customers' data. You can disconnect an assistant at any time from Settings › Connected assistants.
