Terms of Service

These Terms of Service (“Terms”) govern your access to and use of Books2BI, including the website and web application at books2bi.com (together, the “Service”), provided by COSTTRAIL INC, an Indiana corporation (“we”, “us”). By creating an account or otherwise using the Service, you agree to these Terms on behalf of yourself and, if applicable, the organization you represent.

1. The Service

Books2BI lets you design record-keeping screens for your business, keep double-entry books behind them, upload documents (such as bills, receipts, payslips, statements and spreadsheets) to be read onto those screens, produce reports and invoices, and ask questions about your books (together with what you enter, “Customer Data”).

2. Accounts and teams

You must be at least 18 years old and able to enter into a contract. You are responsible for keeping your credentials confidential and for all activity under your account. Tell us promptly at support@costtrail.io if you suspect unauthorized access. If you create an account for an organization, you confirm you have authority to bind it to these Terms.

A workspace owner may invite teammates. Teammates can see and work in the workspace's books and documents and use its token balance; each person's chat history stays private to them. The owner is responsible for who they invite and may remove members at any time.

3. Tokens and purchases

• Tokens. AI work — designing a tracker, reading a document, answering a question — and opening reports consume tokens from your workspace's balance as described on our pricing page. New accounts receive a free token grant at our discretion.
• Token packs. Tokens are sold as one-time packs. There is no subscription and no automatic renewal. Tokens do not expire while your account remains open.
• Payments. Purchases are processed by our payment partner, Lemon Squeezy, which acts as merchant of record and handles applicable taxes and receipts. We do not store card numbers.
• No cash value. Tokens have no cash value and cannot be transferred between accounts.
• Price changes. We may change pack prices or token rates for future purchases; changes never affect tokens you have already bought.

4. Acceptable use

You agree not to, and not to permit anyone to:

• Upload content you have no right to use, or content that is unlawful, infringing or malicious (including malware).
• Use the Service for any unlawful purpose, including to falsify records or evade tax, or to infringe anyone's rights.
• Reverse engineer, resell, or use the Service to build a competing product, except as permitted by law.
• Circumvent token metering, rate limits or security controls, or probe the Service for vulnerabilities without authorization. Responsible-disclosure reports go to support@costtrail.io.
• Use the Service in breach of applicable export-control or sanctions laws.

We may suspend access if continued use threatens the integrity or security of the Service or breaches these Terms.

5. Your data

You retain all rights to Customer Data. You grant us a limited licence to host, copy, process and display Customer Data solely to provide the Service to you and your workspace, as described in our Privacy Policy. We do not use Customer Data to train AI models. You can export your data and delete documents at any time.

6. Not professional advice

Screens, posting rules, extracted fields, reconciliations, reports and answers are produced with the help of AI systems and can be wrong or incomplete. Review what is read from a document before approving it, and check reports before relying on them. The Service does not provide accounting, tax, legal or financial advice and does not replace a qualified professional; you remain responsible for your books, filings and tax obligations.

7. Automatic masking of sensitive data

When you upload a document, the Service automatically detects and masks certain sensitive data — such as card numbers, full bank account numbers, government ID numbers, dates of birth and medical record numbers — before the content is stored, indexed or sent to an AI model, as described in our Privacy Policy. Values your books need, such as tax registration numbers and payment references, are kept.

• Best effort, not a guarantee. Detection is automated and may not identify every instance — for example values in unusual formats, inside images or handwriting, or split across lines or cells — and it may occasionally mask values that are not sensitive.
• Not a compliance certification. Masking is a safeguard. It does not by itself make your use of the Service compliant with laws or standards that apply to you, such as GDPR, India’s Digital Personal Data Protection Act or PCI DSS.
• Your responsibility. You remain responsible for deciding what to upload and for meeting your own legal, regulatory and contractual obligations. Do not upload data you are not permitted to store or share, such as card security codes.
• Tell us if something was missed. If you see a sensitive value that was not masked, delete the document and let us know at support@costtrail.io.

8. Security

We maintain administrative, physical and technical safeguards designed to protect Customer Data, including encryption in transit and at rest, per-workspace access controls, least-privilege access and monitoring. You are responsible for the security of your own devices and credentials.

9. Intellectual property

The Service, including its software, user interfaces, documentation and branding, is and remains the property of COSTTRAIL INC and its licensors. Feedback you choose to send may be used without obligation.

10. Third-party services

The Service relies on third-party services such as Amazon Web Services and Lemon Squeezy. Those services are governed by their own terms.

11. Term and termination

These Terms apply while you have an account. You may close your account at any time from the Your data page or by contacting us. We may suspend or terminate the Service for material breach or where required by law. On termination we delete Customer Data and account information as described in our Privacy Policy, subject to retention required by law.

12. Disclaimers

Except as expressly stated, the Service is provided “AS IS” and “AS AVAILABLE”. To the maximum extent permitted by law, we disclaim all warranties, express or implied, including merchantability, fitness for a particular purpose, title and non-infringement.

13. Limitation of liability

To the maximum extent permitted by law, neither party will be liable for indirect, incidental, special, consequential or punitive damages, including loss of profits, revenue, data or goodwill. Each party’s aggregate liability arising out of these Terms will not exceed the amounts you paid us for the Service in the 12 months before the event giving rise to liability. These limits do not apply to your payment obligations or indemnification obligations.

14. Indemnification

You will defend and indemnify COSTTRAIL INC against third-party claims arising from your Customer Data, your use of the Service in breach of these Terms, or your violation of law. We will defend and indemnify you against third-party claims that the Service, as provided by us and used within these Terms, infringes a third party’s intellectual-property rights.

15. Governing law

These Terms are governed by the laws of the State of Indiana, USA, without regard to conflict-of-laws rules. The parties agree to the exclusive jurisdiction of the state and federal courts located in Hamilton County, Indiana, except that either party may seek injunctive relief in any court of competent jurisdiction.

16. Changes

We may update these Terms. Material changes will be posted here with a new “Last updated” date and, where appropriate, communicated by email or in-product notice. Continued use after the effective date means you accept the updated Terms.
