By creating an account or using the App, you accept these Terms and our Privacy Policy. If you don't agree, don't use the App.

1. What LenDan is

LenDan is a billing, inventory, and khata (credit ledger) tool for small shops. It lets you create bills by voice, photo (parcha), or touch; track stock; keep customer/supplier credit ledgers; print and share receipts; and view business insights. Some features use artificial intelligence (speech recognition and language models) to draft bills and inventory entries from your voice or photos.

2. Eligibility and your account

• You must be at least 18 years old and using the App for a business purpose (running or managing a shop).
• Your account is created with your phone number, verified by OTP. Keep your phone and SIM secure — anyone with access to your OTP can access your shop's data. Tell us immediately if you suspect unauthorised access.
• One account represents one shop. You are responsible for everything done under your account.

3. AI features — drafts, not decisions

The App's voice, parcha, and AI-assist features draft bills and inventory entries for you. Speech recognition and AI parsing make mistakes — wrong items, wrong quantities, wrong prices, wrong names — especially with unusual words, noisy environments, or unclear photos.

You must review every AI-drafted bill or entry before saving, settling, or sending it. The App is deliberately designed so that nothing is charged, saved, or sent to a customer without your confirmation. By using the AI features you accept that:

• We make no guarantee of accuracy of any transcription, parsed bill, drafted message, or AI suggestion.
• The amounts, items, and balances in your records are your records — you confirm them, and you are responsible for their correctness.

4. Your business, your responsibility

• Tax and GST. The App lets you store GST numbers, rates, and HSN codes and print them on receipts, but it is not a tax adviser and does not guarantee tax-compliant invoices. Ensuring your bills, GST details, rates, and filings comply with applicable tax law is entirely your responsibility. Verify figures with your accountant.
• Your customers' data. You enter your customers' names, numbers, and credit balances into the App. As set out in the Privacy Policy (Section 5), you are the data fiduciary for that data — collect and use it lawfully.
• Messages you send. Reminders, statements, and promotions drafted in the App are sent from your own WhatsApp/SMS after your review. You are responsible for their content and for complying with laws on commercial messaging. Don't harass or spam anyone.
• Ledger disputes. Khata balances are records you keep; the Company is not a party to, and does not mediate, any debt or dispute between you and your customers or suppliers.

5. Acceptable use

You agree not to:

• use the App for anything unlawful, fraudulent, or deceptive (including fake invoices or falsified records);
• enter another person's data without the right to do so;
• attempt to breach, probe, or overload our systems or security rules, or access another shop's data;
• reverse-engineer, copy, resell, or create derivative works of the App except as law permits;
• abuse the AI features (e.g. attempting to extract the underlying models or using them for purposes unrelated to your shop);
• use the App to send spam or unsolicited messages.

We may suspend or terminate accounts that violate these Terms.

6. Your content and our licence

Everything you enter — shop details, inventory, bills, parties, khata entries, your payment QR — remains yours. You grant us a limited licence to store and process it solely to provide the App to you (including sending voice audio and parcha images to our AI processors, as described in the Privacy Policy). We claim no other rights over your business data.

7. Offline use and data

The App works offline and syncs when you're back online. Until a device syncs, its data exists only on that device — if the device is lost, reset, or the App is uninstalled before syncing, unsynced data cannot be recovered. Keep your device connected periodically.

8. Fees

The App is currently free to use. If we introduce paid plans or features, we will announce pricing in advance, and continued use of paid features will require your acceptance.

9. Availability and changes

We work hard to keep the App available, but it is provided "as is" and "as available" — we do not promise uninterrupted or error-free operation. Parts of the App depend on third-party services (Google Firebase, Google Gemini, Sarvam AI, Deepgram, WhatsApp/SMS on your device) that we do not control. We may add, change, or remove features, and may discontinue the App with reasonable notice, during which you can export or record your data.

10. Limitation of liability

To the maximum extent permitted by Indian law:

• The Company is not liable for indirect, incidental, special, or consequential losses — including lost profits, lost business, lost data (including unsynced offline data), tax penalties, or disputes with your customers — arising from your use of, or inability to use, the App.
• The Company's total aggregate liability for all claims relating to the App is limited to the amount you paid us for the App in the twelve (12) months before the claim — or ₹1,000, whichever is greater, if you paid nothing.
• Nothing in these Terms limits liability that cannot be limited under applicable law, or your statutory rights as a consumer under Indian law.

11. Indemnity

You agree to indemnify the Company against claims, losses, and expenses (including reasonable legal fees) arising from your breach of these Terms, your violation of law, or your infringement of others' rights — including claims by your customers about data you entered or messages you sent.

12. Termination

• By you: stop using the App and/or delete your account (More → Delete Account) at any time.
• By us: we may suspend or terminate your access if you materially breach these Terms, create risk or legal exposure for us, or where required by law. Where practical, we'll notify you and give you a chance to remedy the breach first.

Sections that by their nature should survive termination (4, 6, 10, 11, 13) survive it.

13. Governing law and disputes

These Terms are governed by the laws of India. Subject to any mandatory consumer-law rights, the courts at Paschim Medinipur, West Bengal, India have exclusive jurisdiction over disputes arising from these Terms or the App. Before going to court, please contact us — most issues can be resolved by our grievance officer:

14. Changes to these Terms

We may update these Terms. We'll update the "Last updated" date above and, for material changes, notify you in the App. Continued use after a change means you accept the updated Terms.

15. Miscellaneous

• If any part of these Terms is held unenforceable, the rest remains in force.
• Our failure to enforce a provision is not a waiver of it.
• You may not assign these Terms; we may assign them as part of a corporate reorganisation or sale, with notice to you.
• These Terms plus the Privacy Policy are the entire agreement between you and the Company about the App.
