Last Updated: March 1, 2026
These Terms of Service ("Terms") govern your access to and use of 24 Engine, a commercial real estate lease analysis application ("24 Engine," "we," "us," or "our"), accessible at https://24engine.com.
By creating an account or using the Service, you agree to be bound by these Terms. If you do not agree, do not use the Service.
1. Service Description
24 Engine is a software tool that performs mathematical calculations and financial modeling for commercial real estate lease analysis. Features include rent schedule modeling, escalation calculations, net effective rent (NER) computation, net present value (NPV) analysis, GAAP (ASC 842) compliance estimates, scenario comparison, and optional AI-powered document extraction.
2. Eligibility
The Service is intended for commercial real estate professionals, including brokers, analysts, landlords, and tenants, operating in a business capacity. You must be at least 18 years of age and authorized to enter into these Terms on behalf of yourself or your organization.
3. Accounts and Access
Certain features of the Service, such as basic lease calculations and manual data entry, may be accessible without creating an account. Other features, including saved projects, AI-powered document extraction, and advanced analytics, may require you to create an account using a valid email address. We reserve the right to change which features require an account at any time.
If you create an account, you are responsible for maintaining the confidentiality of your account credentials and for all activity that occurs under your account. You agree to notify us immediately of any unauthorized access.
4. Not Financial, Legal, Tax, or Investment Advice
24 Engine provides mathematical calculations and estimations for informational purposes only. The Service does not provide financial, legal, tax, or investment advice.
You must independently verify all calculations and outputs before relying on them in any commercial transaction, negotiation, financial decision, or regulatory filing.
We make no representation that the calculations produced by the Service are error-free, complete, or suitable for any particular transaction. Real estate transactions involve complex legal and financial considerations that require the advice of qualified professionals.
5. User Content and Ownership
5.1 Your Content
You retain all ownership rights in the data, documents, and content you provide to the Service ("User Content"), including uploaded PDFs, letters of intent, term sheets, lease abstracts, and manually entered scenario data.
5.2 License to Process
By submitting User Content to the Service, you grant 24 Engine a limited, non-exclusive, non-transferable license to process, transmit, and temporarily store your content solely for the purpose of providing the Service to you. This license terminates when you delete your content or your account.
5.3 AI-Powered Document Extraction
When you use the AI extraction feature to upload a document, text is extracted from your uploaded PDF on our server, transmitted to Anthropic via its commercial API for structured extraction, and returned to your scenario. We do not permanently store the raw uploaded PDF file or extracted text beyond the duration of the extraction request.
Anthropic may temporarily retain API inputs and outputs for up to 30 days in accordance with its commercial data retention policies, unless a zero-data-retention agreement is in place. By using the AI extraction feature, you acknowledge and consent to this processing.
5.4 Confidentiality and AI Model Training
24 Engine uses Anthropic's commercial enterprise API. Under Anthropic's Commercial Terms of Service, Anthropic does not use your uploaded data, extracted text, or any inputs and outputs from the Service to train its foundational AI models. For more information, refer to Anthropic's Commercial Customer Privacy Center.
6. Acceptable Use
You agree to use the Service only for lawful commercial real estate analysis purposes. You may not reverse engineer the Service, scrape or systematically extract data, abuse extraction resources, interfere with operation, circumvent limits or access controls, misrepresent outputs as certified professional opinions, share account credentials, or use the Service in any manner that violates applicable laws or regulations.
7. Suspension and Termination
We reserve the right to suspend or terminate your account, without prior notice, if we reasonably determine that you have violated these Terms, abused API or system resources, or engaged in conduct that threatens the integrity, security, or availability of the Service. Upon termination, your right to access the Service ceases immediately. You may request an export of your data prior to or within a reasonable period following termination.
8. Intellectual Property
The Service, including its calculation engine, user interface, design, code, and documentation, is owned by 24 Engine and protected by applicable intellectual property laws. These Terms do not grant you any rights to our intellectual property other than the limited right to use the Service as described herein.
9. Third-Party Services and Data
The Service integrates with third-party data sources, including NYC Open Data, the NYC Geoclient API, and the NYC Department of Finance. Data retrieved from these sources is provided by their respective operators and is subject to their terms and accuracy. 24 Engine does not guarantee the accuracy, completeness, or timeliness of third-party data and is not responsible for errors originating from external sources.
10. Disclaimer of Warranties
THE SERVICE IS PROVIDED ON AN "AS IS" AND "AS AVAILABLE" BASIS. TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, 24 ENGINE DISCLAIMS ALL WARRANTIES, EXPRESS OR IMPLIED, INCLUDING WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, ACCURACY, AND NON-INFRINGEMENT.
We do not warrant that the Service will be uninterrupted, error-free, or free of harmful components, or that calculation outputs will be accurate or complete for any particular use case.
11. Limitation of Liability
TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, 24 ENGINE, ITS OWNER, AND ITS AFFILIATES SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, INCLUDING LOSS OF PROFITS, LOSS OF DEALS, LOSS OF DATA, OR BUSINESS INTERRUPTION, ARISING OUT OF OR RELATED TO YOUR USE OF THE SERVICE, REGARDLESS OF THE THEORY OF LIABILITY.
IN NO EVENT SHALL OUR TOTAL AGGREGATE LIABILITY EXCEED THE GREATER OF (A) THE AMOUNTS YOU HAVE PAID TO 24 ENGINE IN THE TWELVE (12) MONTHS PRECEDING THE CLAIM, OR (B) ONE HUNDRED DOLLARS ($100).
12. Indemnification
You agree to indemnify, defend, and hold harmless 24 Engine and its owner from any claims, damages, losses, liabilities, and expenses (including reasonable attorneys' fees) arising out of or related to your use of the Service, your violation of these Terms, your reliance on any calculation or output produced by the Service, or any dispute arising from a transaction in which the Service was used.
13. Modifications to Terms
We may update these Terms from time to time. If we make material changes, we will notify you by posting the updated Terms on the Service and updating the "Last Updated" date. Your continued use of the Service after such changes constitutes acceptance of the revised Terms.
14. Governing Law
These Terms shall be governed by and construed in accordance with the laws of the State of New York, without regard to its conflict of laws principles. Any disputes arising under these Terms shall be subject to the exclusive jurisdiction of the state and federal courts located in New York County, New York.
15. Severability
If any provision of these Terms is held to be invalid, illegal, or unenforceable, the remaining provisions shall continue in full force and effect. The invalid provision shall be modified to the minimum extent necessary to make it valid and enforceable while preserving its original intent.
16. Waiver
Our failure to enforce any right or provision of these Terms shall not constitute a waiver. Any waiver must be in writing and signed by an authorized representative of 24 Engine.
17. Assignment
You may not assign or transfer these Terms, or any rights or obligations hereunder, without our prior written consent. We may assign these Terms in connection with a merger, acquisition, reorganization, or sale of substantially all of our assets.
18. Force Majeure
24 Engine shall not be liable for any failure or delay in performing its obligations under these Terms to the extent that such failure or delay results from circumstances beyond its reasonable control, including acts of God, natural disasters, pandemic, government actions, power failures, internet or telecommunications outages, or third-party service provider failures.
