Terms of Use

Last updated: 28 September 2026

These Terms of Use (“Terms”) are a binding agreement between you and Shri Mahendra Industries (“we”, “us”), the owner of SMI Books — the Windows and Android apps, the website https://smibooks.in, the online sync service and every related service (together, the “Service”). By creating an account, installing the app, starting a trial, paying for a plan or otherwise using the Service, you accept these Terms, our Privacy Policy and our Refund & Cancellation Policy. If you do not agree, do not use the Service.

1. Business use

The Service is a business tool. You confirm that you use it for the purposes of your trade, business or profession, that you are 18 or older, and that you are authorised to accept these Terms for the business you register. If you register on behalf of a business, “you” means that business and the person accepting.

2. Licence

We grant you a limited, non-exclusive, non-transferable, non-sub-licensable and revocable right to use the Service for your own business, on up to the number of devices your plan allows, for as long as you have an active trial or paid plan and follow these Terms. The Service, its software, design, content, name and logo belong to us. You may not copy, modify, resell, rent, share accounts between businesses, reverse-engineer, decompile, or try to get around plan limits, device limits, licence checks or security.

3. Your account and your team

• You are responsible for the accuracy of the details you register, for keeping your password and devices secure, and for everything done under your account.
• People you invite to your business act on your behalf. You choose their roles and permissions and you are responsible for what they see and do, including anything they change, delete or share.
• Tell us at once at support@smibooks.in if you suspect unauthorised use.

4. Free trial

A new business may get one free trial of the period shown in the app (currently 30 days). One trial is allowed per business, person, GSTIN and payment method. We may refuse, shorten or end a trial where we believe it is being reused or misused. A trial is provided without any warranty and is your opportunity to decide whether the Service suits your business before you pay.

5. Plans, prices and payment

• Plans are prepaid for one month or one year and give the features and number of devices described for that plan at the time you buy it. Please read the plan details before paying.
• Prices are in Indian Rupees and exclude GST, which is charged extra as applicable.
• Payments are processed by Razorpay or, where applicable, by Google Play or the Microsoft Store, under their own terms. We do not receive or store your card, UPI or bank details.
• A plan becomes active after the payment is confirmed to us. Plans do not renew by themselves.
• We may change prices, plans and plan contents at any time. A change never affects a period you have already paid for; it applies from your next purchase or renewal.
• Refunds are governed only by our Refund & Cancellation Policy.

6. When a plan or trial ends

When a trial or plan ends and is not renewed, the Service becomes read-only: your records stay readable and exportable, but new entries cannot be saved until you buy a plan. If an account has had no active plan for 12 months, we may, after at least 30 days’ notice to the registered email, permanently delete its cloud data. Data on your own devices and in your own Google Drive backups is under your control.

7. Your data and your responsibility for it

• The business records you enter belong to you. You give us permission to store, copy, process and transmit them only as needed to run, secure, support and improve the Service, as described in the Privacy Policy.
• You are solely responsible for the records you enter and for everything you issue or file using them — invoices, e-way bills, GST returns, tax payments, accounts and any report given to a customer, bank or authority. The Service is a software tool; it is not tax, legal, accounting or financial advice. Always have your figures checked by your own accountant or CA before you rely on or file them.
• Keep your own regular backups (the app can back up to your own Google Drive and export files). We are not responsible for data lost through deletion by you or your team, lost or damaged devices, uninstalling the app, clearing app data, restoring an old backup, your internet connection, or third-party services.

8. Acceptable use

You must not use the Service for anything unlawful, to issue false or fake invoices, to evade tax, to store content you have no right to, to attempt to access another business’s data, to probe or break its security, to overload it, or to resell it. We may investigate suspected misuse and cooperate with lawful requests from authorities.

9. Suspension and termination

We may suspend or terminate your access, with or without notice, if you breach these Terms, if a payment fails or is reversed or charged back, if we suspect fraud or misuse, or if the law or an authority requires it. No refund is due in any of these cases. You may stop using the Service at any time; before you go, export your data. Sections 7, 10 to 15 continue after termination.

10. Availability, updates and changes

We continuously update the Service and may add, change or remove features, screens and supported devices or operating systems. The online service depends on third parties (such as Google Firebase, Google Drive, Razorpay, WhatsApp, Google Play and Microsoft) and on the internet, and may occasionally be slow or unavailable; the apps keep working offline. We do not guarantee that the Service will be uninterrupted, error-free, or that it will meet every requirement of your business.

11. Disclaimer

To the fullest extent permitted by law, the Service is provided “as is” and “as available”, without warranties of any kind, express or implied, including fitness for a particular purpose, merchantability, accuracy or non-infringement.

12. Limitation of liability

To the fullest extent permitted by law: (a) we are not liable for any indirect, incidental, special or consequential loss, or for loss of profit, revenue, business, goodwill, data, or tax, interest or penalties, however caused; and (b) our total liability for all claims relating to the Service is limited to the amount you actually paid us for the Service in the three (3) months before the event giving rise to the claim. Nothing in these Terms limits liability that cannot be limited by law.

13. Indemnity

You will indemnify and hold us, our owners and staff harmless from any claim, demand, loss, penalty or cost (including reasonable legal fees) arising from your use of the Service, your data, your invoices and filings, your team’s actions, or your breach of these Terms or of any law.

14. Changes to these Terms

We may update these Terms at any time by posting the new version here with a new date. Continued use of the Service after that date means you accept the updated Terms.

15. Law, disputes and jurisdiction

These Terms are governed by the laws of India. Before starting any proceedings, you agree to first write to us at support@smibooks.in and allow 30 days to resolve the matter. Subject to that, the courts at Sitamarhi, Bihar have exclusive jurisdiction over any dispute arising from these Terms or the Service.

16. General

These Terms, the Privacy Policy and the Refund & Cancellation Policy are the entire agreement between you and us about the Service. If any part is found unenforceable, the rest remains in force. Our not enforcing a right is not a waiver of it. You may not transfer your account or these Terms; we may transfer them to a successor of our business. We are not liable for delay or failure caused by events beyond our reasonable control.

17. Contact and grievances

Questions, complaints and grievances: write to the address below. We acknowledge within 48 hours and aim to resolve within 15 days.
