Terms of Service

Last updated: 2 November 2026

These Terms of Service ("Terms") govern your use of Digital Nexus (MCP), the online service at mcp.digitalnexus.tech that syncs data from TallyPrime to a secure online dashboard and lets you query it with Claude AI (the "Service"). The Service is operated by Digital Nexus ("Digital Nexus", "we", "us" or "our"). By creating an account or using the Service, you agree to these Terms.

1. The Service

Digital Nexus provides a small sync program (the "Connector") that you install on a Windows PC running TallyPrime. The Connector reads ledgers, vouchers, stock items and related data from TallyPrime and sends them to your Digital Nexus account over an encrypted connection. You can then view reports in your online dashboard and, if you choose, connect Claude AI to ask questions about that data.

The Connector has read-only access to Tally. It does not create, change or delete any entry in your Tally company.

2. Your account

• You must be at least 18 years old and able to enter into a binding contract under Indian law. If you use the Service for a business, you confirm that you are authorised to accept these Terms on its behalf.
• You sign in with your email address using a one-time code or a passkey. Keep access to your email account and devices secure; you are responsible for activity under your account.
• Each account is one organisation. The account owner can invite team members, who can view the organisation's data. The owner is responsible for who they invite.
• Sync keys are like passwords for the Connector. Do not share them. You can revoke a key at any time from the Connect page.
• Please give us accurate details, including your business name, mobile number and GSTIN where applicable, so that invoices are correct.

3. Free trial

• Every new organisation receives a free trial of 7 (seven) days, starting when the account is created. During the trial you can use the Service with the limits of the Growth plan (up to 3 Tally companies).
• No payment details are required to start the trial, and you will not be charged at the end of it automatically.
• The free trial is available once per email address. Creating another account with the same email address, or deleting your account and signing up again, does not give a new trial. We may also refuse or end a trial that we reasonably believe is being misused, for example several accounts created for the same business.
• When the trial ends, syncing, reports and Claude AI access are paused until you choose a paid plan. Your synced data is kept so that you can continue where you left off.
• If you buy a plan during the trial, the paid plan starts immediately and the remaining trial days end.

4. Plans, prices and payment

• Plans are priced by the number of Tally companies you connect. Current prices are shown on our pricing page and in your dashboard under Billing.
• All prices are in Indian rupees (INR) and are exclusive of GST. GST at the applicable rate (currently 18%) is added at checkout and shown on your invoice.
• Payments are processed by Razorpay Software Private Limited ("Razorpay") using UPI AutoPay, debit or credit cards, net banking or other methods Razorpay supports. We do not see or store your full card number, UPI PIN or banking passwords. Your use of Razorpay is also subject to Razorpay's terms.
• Subscriptions are billed in advance for each monthly or yearly period.

5. Automatic renewal

When you subscribe, you authorise us, through Razorpay, to charge the plan price plus GST at the start of every billing period until you cancel. This is a recurring payment mandate as permitted under applicable Reserve Bank of India rules, and your bank or card issuer may send you a notification before each charge.

• If a renewal payment fails, Razorpay will retry it. Your access continues for a grace period of 3 days after the paid period ends. If payment still has not been received, syncing, reports and Claude AI access are paused until the plan is renewed.
• We may change our prices. A new price applies to new subscriptions, and to an existing subscription only after we have given you at least 30 days' notice by email. If you do not agree to a new price, you can cancel before it takes effect.

6. Cancellation, plan changes and refunds

• You can turn off auto-renewal at any time from Dashboard > Billing. Your plan remains active until the end of the current paid period, and you will not be charged again.
• If you switch to another plan, the new plan starts immediately with a new billing period and the old subscription is cancelled. No refund or credit is given for the unused part of the previous plan.
• Fees are non-refundable. We do not give refunds or credits for partial months or years, for unused time, for unused company slots, or when you cancel, downgrade or delete your account before the end of a paid period.
• The limited cases in which we do refund, such as a duplicate charge, are set out in our Refund and Cancellation Policy, which forms part of these Terms.

7. Your data

• You own all data that you sync from Tally and all information you add to the Service ("Your Data"). You give us permission to store, process and display Your Data only to provide the Service to you and your team.
• Your Tally data may contain details of your customers and suppliers, such as names, GSTINs, phone numbers and email addresses. You are responsible for having the right to share that data with the Service.
• We handle personal data as described in our Privacy Policy.
• You can remove a Tally company and its synced data at any time from the Connect page, or delete your whole account (see section 11).

8. Claude AI

If you connect Claude, the AI assistant made by Anthropic, Claude can read Your Data through our secure connection in order to answer your questions. You choose whether to connect it, and you can disconnect it at any time. Your use of Claude is also subject to Anthropic's own terms and policies.

AI answers can be incomplete or wrong. Always check important figures in Tally before relying on them.

9. Reports are not professional advice

Reports, statements and AI answers are prepared automatically from the data synced at the time of the last sync. They may differ from Tally if a sync is incomplete, if entries were changed after the last sync, or if your Tally data contains errors. The Service does not provide accounting, tax, legal or financial advice. Please verify final figures in Tally and consult a qualified professional before making filings or decisions.

10. Acceptable use

You agree not to:

• use the Service for anything unlawful, or to store data you do not have the right to use;
• try to access another organisation's data, probe or break our security, or interfere with the Service;
• copy, resell, or reverse engineer the Service or the Connector, except where the law allows this;
• share sync keys or accounts outside your organisation, or use automated means to overload the Service.

We may suspend or close an account that breaks these rules, puts other users at risk, or is used for fraud. Where reasonable, we will tell you first and give you a chance to fix the problem.

11. Deleting your account

• The account owner can permanently delete the account at any time from Dashboard > Settings > Delete account.
• Deleting the account cancels any active subscription, stops all sync keys and team access, and permanently erases all synced Tally data. This cannot be undone.
• No refund is given for the remaining part of a paid period when you delete your account.
• We keep payment and invoice records for as long as tax and accounting laws require, even after the account is deleted.

12. Availability and changes to the Service

We work to keep the Service available at all times, but it may occasionally be unavailable because of maintenance, failures of our hosting, internet or payment providers, or events beyond our control. We may improve or change features from time to time. If we make a change that significantly reduces a paid feature you rely on, we will tell you in advance.

13. Third-party services and trademarks

The Service relies on third-party providers, including our cloud hosting provider, Razorpay for payments and, if you choose, Anthropic for Claude AI. Tally and TallyPrime are trademarks of Tally Solutions Private Limited. Claude is a trademark of Anthropic. Digital Nexus is an independent service and is not affiliated with, endorsed by or sponsored by Tally Solutions or Anthropic.

14. Disclaimer and limitation of liability

The Service is provided "as is" and "as available". To the fullest extent permitted by law, we do not give any warranty that the Service will be uninterrupted, error-free, or fit for a particular purpose.

To the fullest extent permitted by law, we are not liable for any indirect, incidental, special or consequential loss, or for loss of profits, revenue, business or data, arising from your use of the Service. Our total liability for any claim relating to the Service is limited to the amount you paid us for the Service in the three (3) months before the event giving rise to the claim. Nothing in these Terms limits any liability that cannot be limited under Indian law.

15. Indemnity

You agree to compensate us for reasonable losses and costs arising from a third-party claim caused by your breach of these Terms or your misuse of the Service, including data you upload without the right to do so.

16. Termination

You may stop using the Service at any time. We may end these Terms or suspend the Service for your account if you seriously or repeatedly break them, if required by law, or if we stop offering the Service. If we stop offering the Service for reasons other than your breach, we will give you at least 30 days' notice and refund any fees you have paid for the period after the Service ends.

17. Governing law and disputes

These Terms are governed by the laws of India. We encourage you to contact us first so that we can try to resolve any concern informally. Subject to that, the courts at the place where our business is registered shall have exclusive jurisdiction over any dispute arising from these Terms or the Service.

18. Changes to these Terms

We may update these Terms from time to time. We will post the updated version on this page with a new "Last updated" date, and for material changes we will notify account owners by email at least 15 days before they take effect. Continuing to use the Service after the changes take effect means you accept them.
