Privacy Policy

Last updated: 2026-10-25

SwarnBill ("the app") is a billing, stock and ledger app for jewellery shops, run by SwarnBill (proprietor: Kanhaiya Kumar) ("we"). This policy explains what we collect, why, who sees it, and how you can delete it. The app is meant for business owners and staff aged 18 or above.

1. What we collect

Data	Why
Owner e-mail address, name, 4-digit PIN (stored only as a salted one-way hash)	Create and secure your account; send login codes
Shop name, Shop ID, firms/outlets, staff names, staff IDs, phone numbers, permissions, staff passwords (one-way hash)	Run your multi-user shop
Business data you enter: customers (name, phone, address, GST number), bills, stock, rates, ledger, old-metal and cash entries	Store and sync your data to all your phones; keep it safe if a phone is lost
Phone model name and a random device ID, last-seen time, approximate network address (stored as a one-way hash)	Show "phones signed in", enforce your plan's phone limit, detect abuse
Subscription details: plan, dates, store order number, purchase token (encrypted)	Verify your payment with Google Play or Razorpay and turn your plan on
Support messages and basic account status you send to our help assistant or tickets	Solve your problem
Technical logs (error type, time, route; never your business data, PIN, codes or tokens)	Keep the service running and secure

We do not collect your location, contacts, photos, SMS or advertising ID. We do not show ads and we do not sell your data.

2. Who processes data for us

Cloudflare – hosting, database (D1) and encrypted backups (R2).
Brevo – sends the one-time code e-mails.
Google Play and Razorpay – process subscription payments. We never see or store your card, UPI or bank details.
Anthropic – runs the automated help assistant. Only the question you type and a short, non-sensitive account status are sent; no bills, customers or stock.

3. Security

Connections use HTTPS. PINs and passwords are salted and hashed; backups are encrypted; every shop's data is separated and checked on our server on each request; sign-in from a new phone needs an e-mail code; repeated wrong attempts are blocked. No system is perfectly secure, so please keep your PIN private and sign out lost phones from Account & privacy.

4. How long we keep data

While your account is active: your data stays until you delete it.
After you request deletion: everything is erased after 30 days (sign in within 30 days to cancel). Encrypted backups of it are removed within a further 35 days.
Technical error logs: 90 days. Security/audit entries (event type and time, no business data): kept as needed for security and legal reasons.
Payment records may be kept as the law requires.

5. Your choices

See / download your data: Account & privacy → Download all my data.
Delete your account: in the app (Account & privacy → Delete) or see how to request deletion.
Correct data: edit it in the app; it syncs to your cloud copy.
Questions or complaints: write to the contact below.

6. Your customers' data

You enter your own customers' details. You are responsible for having the right to do so; we only store it for you and do not use it for any other purpose.

7. Changes

If we change this policy in a way that matters, we will show a notice in the app and update the date above.
