Dukanly Privacy Notice
This notice describes what the Dukanly Android app collects, why, and who it is shared with. It supplements our company-wide Singnet Privacy Policy, which covers security, your rights, retention, international transfers and contact details — please read both together.
Dukanly is billing software for a shop. It records what you sell, your stock, your GST invoices, and the credit (udhaar) your customers owe you. Most of what it holds is your business's own records — but the udhaar book contains details about other people, and that part deserves its own section. It is below, and it is the most important thing on this page.
What Dukanly collects
| Category | Examples | Why |
|---|---|---|
| Account & identity | Email address and/or mobile number, password (stored only as a salted BCrypt hash), your name | To create and secure your account and sign you in |
| Your shop | Shop name, address, phone number, GSTIN if you are registered, and what kind of business it is | To identify the shop and to print a correct invoice header |
| Catalogue & stock | Item names, prices, units, HSN codes, GST rates, quantities on hand and corrections you log | To bill from and to tell you what is running out |
| Bills | Each bill's items, quantities, discounts, charges, tax, total, payment method and time | The core purpose of the app, and the record a tax invoice has to be produced from |
| Customers & udhaar | Customer name, mobile number, area, credit limit, running balance and the entries that make it up | To keep the credit book — see Your customers' details |
| Staff | Name, mobile number and the role you give each person who bills on your shop | So the right people can sign in and the wrong ones cannot |
| Technical | IP address, app version, request logs with timestamps, error diagnostics | Security, abuse prevention and reliability |
Your customers' details — please read
When you add a customer to the udhaar book, you are entering another person's name and mobile number into our system. That is different from everything else in the app, and two things follow from it.
Those details are theirs, not ours. We store them only so your credit book works. We do not contact your customers, do not market to them, do not sell their details, and do not use them for any purpose of our own. We have no relationship with them — you do.
You are the one who collected them. Under Indian data protection law the shop that enters a customer's details is responsible for having a reason to hold them, for keeping them accurate, and for removing them when they are no longer needed. In practice: add a customer's number because you need it for the khata, tell them you are keeping it if they ask, and delete the record once the account is settled and you no longer need it. We give you the means to delete; the judgement is yours.
If one of your customers asks us directly to remove their details, we will refer them to you, because the record is in your shop's book and only you can decide whether it is still needed.
Reminders you send
If you send a payment reminder to a customer, the message leaves your phone through whatever app you choose to send it with — WhatsApp or SMS — and from that point it is handled by that app and its provider under their own terms, not ours. We do not send messages to your customers on your behalf, and we do not pass their numbers to any messaging service ourselves.
What Dukanly does not do
- No advertising. There are no ads in Dukanly and no advertising identifier is used.
- No bank connection. The app never connects to a bank or a payment gateway. Payment method on a bill is simply a label you tap; no money moves through Dukanly.
- No SMS, no call log, no contacts. Customer and staff details are ones you type in.
- No location. The shop address is text you enter, not a position we read.
- No camera. The app does not request camera permission.
- No selling of data, ever — not your records, not your customers' details.
Who we share with
Only the suppliers that run the service, and only as far as each needs:
- Hosting — our servers, where your shop's records are stored.
- Email and SMS delivery — to send the one-time code that verifies your account. The provider sees the address or number the code goes to, and nothing else about your shop.
- Google — if you choose to sign in with Google. Google tells us the email address on the account you pick; we tell Google nothing about your shop, your bills or your customers.
We do not sell personal data, and we do not share it for anyone else's marketing.
Invoices and tax records
A GST tax invoice is a legal document, and Indian tax law requires invoices to be retained — currently for several years from the end of the relevant financial year. Bills therefore are not deleted on request the way other records are; they are kept for as long as the law requires and then removed. The rest of your data follows the retention periods in the company Privacy Policy.
Children
Dukanly is a business tool, is not directed at children, and we do not knowingly collect their personal data.
Security, your rights, retention & contact
These apply across all Singnet products and are described in the company Privacy Policy. To exercise your rights or request deletion, email support@mail.singnet.in — or see how to delete your account.
One consequence of running a shop with other people is worth stating plainly: if you delete your account, records belonging to a shop you do not own — bills raised by another owner, or a khata kept on their shop — remain theirs and are not deleted with yours.
