Terms of Service

Effective date: March 15, 2026

1. Agreement to Terms

By accessing or using LobsterBooks (“the Service”), operated by LobsterBooks LLC (“we,” “us,” or “our”), you agree to be bound by these Terms of Service. If you do not agree, do not use the Service.

These Terms, together with our Privacy Policy, constitute the entire agreement between you and LobsterBooks LLC regarding the Service.

2. Description of Service

LobsterBooks is an AI-powered bookkeeping platform for small businesses. The Service includes transaction categorization, invoice and bill management, receipt scanning, financial reporting, and related features accessible via our web dashboard and messaging integrations.

The Service is not a substitute for professional accounting or tax advice. You are responsible for the accuracy of your financial records and should consult a qualified professional for specific accounting, tax, or legal guidance.

3. Eligibility

You must be at least 18 years old and have the legal authority to enter into a binding agreement. If you are using the Service on behalf of a business, you represent that you have authority to bind that business to these Terms.

4. Account Registration

You must provide accurate and complete information when creating an account. You are responsible for maintaining the confidentiality of your login credentials and for all activity under your account. Notify us immediately if you suspect unauthorized access.

5. Subscription & Billing

LobsterBooks offers a 14-day free trial with full access to all features. No credit card is required to start your trial. Your free trial does not automatically convert to a paid subscription — you must actively choose a plan and subscribe to continue using the Service after the trial period ends.

Subscription plans, pricing, and features are described on our pricing page and may change with prior notice.

Payments are processed by Stripe. By subscribing, you authorize us to charge your payment method on a recurring basis. You may cancel your subscription at any time through your account settings; cancellation takes effect at the end of the current billing period.

Past Due Accounts

If your payment method fails and your account becomes past due, your account will be placed in read-only mode. In read-only mode, you may view and export your data, but you cannot create or edit transactions, invoices, bills, or payments. Full access will be restored once your payment is successfully processed.

Cancelled Accounts

If you cancel your subscription, your account will remain in read-only mode for 30 days following the end of your current billing period. During this period, you may view and export your data, but you cannot create or edit transactions, invoices, bills, or payments. After 30 days, your account will be deactivated.

AI Token Overage

Your plan includes a monthly AI token allocation. Usage exceeding your allocation is billed at the overage rate ($0.50 per 10,000 tokens) via your payment method on file. By subscribing, you authorize these overage charges.

Refunds are handled on a case-by-case basis.

6. Acceptable Use

You agree not to:

  • Use the Service for any unlawful purpose or in violation of any applicable law
  • Attempt to gain unauthorized access to the Service or its related systems
  • Interfere with or disrupt the integrity or performance of the Service
  • Upload or transmit viruses, malware, or other harmful code
  • Attempt to manipulate, exploit, or inject instructions into the Service's AI systems (including prompt injection, role hijacking, or instruction override attacks)
  • Use the AI assistant to generate fraudulent, misleading, or fictitious financial records, invoices, or reports
  • Submit bulk operations designed to corrupt or manipulate accounting data
  • Use the Service to store or process data you do not have the right to use
  • Reverse engineer, decompile, or disassemble the Service
  • Resell, sublicense, or redistribute access to the Service without our written consent

You are solely responsible for all actions performed by the AI assistant on your behalf, including any transactions, invoices, or journal entries it creates at your request.

6a. Security Monitoring & Abuse Detection

To protect the integrity of our AI systems and all users' data, we employ automated security scanning on content processed by the Service, including uploaded documents, receipt images, transaction descriptions, and chat messages. This scanning detects patterns associated with prompt injection, AI manipulation, and other abuse vectors.

When potentially malicious content is detected, we reserve the right to:

  • Neutralize or strip the harmful content before processing
  • Preserve a copy of the original content (including uploaded documents and images) for security investigation
  • Log the event, including metadata such as severity classification, threat type, timestamp, and request context
  • Temporarily throttle or suspend AI features on your account pending review
  • Permanently suspend accounts engaged in repeated or deliberate AI abuse

Flagged content is stored securely and accessible only to our security team. Throttling and suspensions are applied automatically based on severity and frequency. Low-severity events (which may be accidental) are logged but do not affect your account. If you believe your account has been incorrectly restricted, contact support for a manual review.

7. Email Communications

The Service sends emails on your behalf, including invoice delivery, payment reminders, and team invitations, using either our platform email infrastructure or your own SMTP credentials if configured. You are responsible for:

  • The accuracy of all recipient email addresses
  • Compliance with applicable email laws (including CAN-SPAM, CASL, and GDPR email consent requirements) for emails sent through the Service
  • The security and accuracy of any SMTP credentials you provide

We are not liable for emails sent to incorrect addresses, delivery failures caused by recipient mail servers, or legal consequences arising from emails you initiate through the Service.

7a. Your Data

You retain ownership of all financial data, receipts, invoices, and other content you upload to the Service (“Your Data”). You grant us a limited license to process Your Data solely to provide and improve the Service.

You may export Your Data at any time through the export feature in your account settings. Upon account deletion, we will delete Your Data within 30 days, except as required by law.

Exception: Security event data collected pursuant to Section 6a (Security Monitoring) may be retained for up to 12 months after account deletion regardless of account status, as required for platform security.

If you invite team members to your account, you are the data controller for all financial data they access. You are responsible for ensuring your team members' use of the Service complies with these Terms.

For details on how we collect, use, and protect your information, please refer to our Privacy Policy.

8. Intellectual Property

The Service, including its design, software, logos, and content (excluding Your Data), is owned by LobsterBooks and protected by intellectual property laws. These Terms do not grant you any rights to our trademarks, branding, or proprietary technology.

9. AI-Generated Content

The Service uses artificial intelligence (including Anthropic's Claude) to categorize transactions, extract data from receipts, parse natural language, calculate tax estimates, perform revenue recognition calculations, and provide a conversational AI assistant.

IMPORTANT LIMITATIONS

  • AI-generated categorizations, tax estimates, 1099 calculations, and revenue recognition schedules are suggestions only and may contain errors
  • LobsterBooks is not an accounting firm, CPA practice, or tax advisory service
  • You are solely responsible for reviewing, verifying, and approving all AI-generated outputs before they are finalized in your books
  • Tax calculations (including quarterly estimates and 1099-NEC reports) should be verified by a qualified tax professional before filing
  • Revenue recognition schedules (ASC 606) should be reviewed by a certified accountant
  • The AI assistant can create, modify, and delete financial records at your instruction — you are responsible for reviewing all changes it makes
  • AI accuracy depends on the quality and completeness of data you provide

WE EXPRESSLY DISCLAIM ALL LIABILITY FOR: INCORRECT TRANSACTION CATEGORIZATIONS, ERRONEOUS TAX CALCULATIONS, INACCURATE RECEIPT DATA EXTRACTION, INAPPROPRIATE REVENUE RECOGNITION TIMING, OR ANY OTHER AI-GENERATED OUTPUT THAT RESULTS IN FINANCIAL LOSS, TAX PENALTIES, AUDIT CONSEQUENCES, OR REGULATORY NON-COMPLIANCE.

10. Indemnification

You agree to indemnify, defend, and hold harmless LobsterBooks LLC, its officers, directors, employees, and agents from and against any claims, damages, losses, liabilities, costs, and expenses (including reasonable attorneys' fees) arising from or related to:

  • (a) Your use of the Service or violation of these Terms
  • (b) The accuracy or legality of Your Data, including financial records, invoices, and tax documents
  • (c) Any third-party claims arising from emails, invoices, or other communications sent through the Service on your behalf
  • (d) Your reliance on AI-generated outputs without appropriate professional review
  • (e) Any violation of applicable laws, including tax, accounting, or financial reporting regulations, based on your use of the Service

11. Disclaimers

THE SERVICE IS PROVIDED “AS IS” AND “AS AVAILABLE” WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE SERVICE WILL BE UNINTERRUPTED, ERROR-FREE, OR SECURE.

12. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, LOBSTERBOOKS SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR ANY LOSS OF PROFITS OR REVENUES, WHETHER INCURRED DIRECTLY OR INDIRECTLY. OUR TOTAL LIABILITY FOR ANY CLAIM ARISING FROM OR RELATED TO THESE TERMS SHALL NOT EXCEED THE AMOUNT YOU PAID US IN THE 12 MONTHS PRECEDING THE CLAIM.

13. Termination

You may terminate your account at any time through your account settings. We may suspend or terminate your access if you violate these Terms, if required by law, or if we discontinue the Service with reasonable notice.

Upon termination, your right to use the Service ceases immediately. Your data will be retained in read-only mode for 30 days to allow export. After 30 days, your data will be permanently deleted except as required by law or as described in Section 6a.

Sections that by their nature should survive termination (including Disclaimers, Limitation of Liability, Indemnification, and Governing Law) will continue to apply.

14. Force Majeure

We shall not be liable for any failure or delay in performing our obligations under these Terms due to circumstances beyond our reasonable control, including but not limited to: natural disasters, acts of government, internet or telecommunications failures, third-party service outages (including but not limited to Supabase, Anthropic, Stripe, Plaid, and Telegram), power failures, cyberattacks, or pandemics.

15. Assignment

You may not assign or transfer these Terms without our prior written consent. We may assign these Terms in connection with a merger, acquisition, reorganization, or sale of all or substantially all of our assets, with notice to you. Any attempted assignment in violation of this section is void.

16. Changes to Terms

We may update these Terms from time to time. We will notify you of material changes via email or through the Service. Your continued use of the Service after the effective date of revised Terms constitutes acceptance of the changes.
