Terms of use

What you get, what you do not, and what happens if either of us wants to stop.

What the service does

Longbook reads WhatsApp chat exports, documents and photographs that you give it, and writes down what it finds: orders, payments, dispatches, quotes, complaints, party accounts and outstandings. It shows you what it was unsure about so you can confirm or correct it, and it emails you a summary each evening.

It is a record-keeping assistant. It reads what you already have and organises it.

What it does not do

  • It is not a replacement for Tally or your accountant. It does not produce statutory books, ledgers for audit, or anything your accountant can file from directly. It sits before that: what was agreed on WhatsApp, before it becomes a voucher.
  • No GST filing, e-invoicing or e-way bills. We do not touch statutory compliance in any form.
  • No financial, tax or legal advice. Nothing the system shows you is advice. A flag saying a rate looks low or a party is slow to pay is an observation about your own data, not a recommendation about what to do.
  • No invoicing, billing or POS. It does not print or issue your bills.
  • No inventory or stock valuation. It knows what was ordered, not what is on your shelf.
  • It never contacts your customers. Reminder drafts are yours to read, change and send.

Checking the figures is your job

This is the most important paragraph on the page.

The system reads messages using AI, and AI gets things wrong. It will occasionally misread a rate, attach an order to the wrong party, or miss a payment mentioned in passing. That is why every record shows you the messages it came from, and why anything it is unsure about waits for you in Review.

You are responsible for checking any figure before you act on it. Before you chase a payment, send a reminder, price an order or settle an account, verify it against your own records. Do not treat what you see here as the final word on what someone owes you.

We are not liable for losses arising from acting on a figure without checking it: a payment chased that was already made, an order priced from a misread rate, a reminder sent to the wrong party. Our total liability to you in any case is limited to the fees you have paid us in the previous twelve months.

What it costs

₹1,000 per month, or ₹8,000 for a year paid up front, plus ₹2,500 once for setup. Prices are in Indian rupees and exclude any taxes that apply.

Payment is taken in person or by bank transfer. There is nothing to pay for inside the app, and we never ask for card details. Your access is extended by hand once payment is received.

New businesses get a 14-day trial with everything working, before anything is due.

If we change the price, existing customers keep theirs for the term already paid, and we tell you at least 30 days before a renewal at a new rate. Full pricing.

Stopping

  • You can stop whenever you like. Tell us and we stop billing. Monthly means you are paid up to the end of the month you are in.
  • Annual prepaid is refunded pro rata for whole unused months if you leave in the first six months. After that it runs to the end of the year.
  • Setup fees are not refundable once we have done the setup, because the work is done.
  • Your data is not deleted when you stop. It is kept for 90 days in case you come back, then removed. Ask sooner and we delete it within seven days.
  • You can take your data with you at any point, as a spreadsheet. Just ask.

We may end the service if fees go unpaid after we have asked, or if the service is used for something unlawful. We would write to you first.

What we ask of you

  • Only upload chats and documents from your own business: conversations you are a party to, and records you have the right to hold.
  • Keep your access token to yourself. Anyone holding it can see your books. Tell us at once if it is lost and we will issue a new one, which stops the old one working.
  • Do not try to break into other businesses' data, or resell the service as your own.

Availability

We aim to keep the service running during working hours and will fix breakages as fast as we reasonably can, but we do not promise an uptime figure and we are a small team. Reading a long history takes minutes, not seconds, and depends on a Google service we do not control.

Your records are backed up daily. If we lose data through our own fault, we will tell you.

The legal bits

These terms are governed by Indian law, and the courts of Gujarat have jurisdiction. If any part of this page is unenforceable, the rest still stands.

If we change these terms materially, we will tell you by email before the change takes effect.

How we handle your data is set out separately in the privacy policy, which is part of these terms.

Questions go to a person: longbook.co@gmail.com or longbook.co@gmail.com.
