Terms of use
Last updated 10 November 2026
These terms apply when you use the SureBook app and this website. By using them, you agree to these terms. If you do not agree, please do not use the app.
Who we are
SureBook is made by Vempus. "We" means Vempus and "you" means the person using the app.
What SureBook is
SureBook is a free notebook on your phone for udhar records and a cashbook. It is a record-keeping tool. It is not a bank, a wallet or a payment service, and it is not accounting, tax or legal advice.
Money and payments
- SureBook never holds, moves or receives money. When a customer pays with UPI, their UPI app pays your bank account directly.
- SureBook does not check whether a payment reached you. Check your bank or UPI app before you write down that you got money.
- SureBook never gives money to anyone and charges no fees.
Your records
- Your records are kept only on your phone. You are responsible for them, including keeping a backup. If the phone is lost, reset or the app is uninstalled without a backup, the records are gone and we cannot bring them back.
- Balances, cash in hand and totals are worked out from what you enter. Check them before you rely on them or settle money.
- Only record people whose details you need for your business, and keep their information private. This includes customer lists you bring in from a file.
Reminders and messages
- SureBook never sends a message by itself. It opens WhatsApp or your SMS app with a message typed, and you decide whether to send it.
- You are responsible for the messages you send. Send reminders only to people who owe you, keep them polite, and do not use the app to threaten, harass or mislead anyone.
Fair use
Do not use SureBook for anything illegal, or to copy, sell or misuse the app. Do not try to break the app or this website.
No guarantee
We work to keep SureBook correct and reliable, but the app and website are given "as is", without any guarantee. As far as the law allows, Vempus is not responsible for any loss that comes from using the app, including lost records, wrong entries, missed payments or decisions made from its numbers.
Changes
We may change the app and these terms. If the terms change, the new version will be on this page with a new date. Using the app after a change means you accept the new terms.
Law
These terms are governed by the laws of India.
