Terms of Service Agreement

Effective date: July 11, 2026.

This Terms of Service Agreement (the “Agreement” or “Terms”) is a binding contract between OpSynx AI (“OpSynx AI,” “we,” “us,” or “our”), the owner and provider of the OpSynx AI real-estate data and workflow platform (the “Platform” or “Service”), and the business entity that subscribes to, accesses, or uses the Service (the “Customer,” “you,” or “your”). The Service is delivered on a multi-tenant basis; each Customer is provisioned as a distinct sub-account on the OpSynx AI Platform. By creating an account, clicking to accept, executing an order form, or accessing or using the Service, the individual accepting these Terms represents that they are authorized to bind the Customer, and the Customer agrees to be bound by this Agreement. If you do not agree, do not access or use the Service.

1. Definitions

2. The Service and sub-accounts

OpSynx AI operates the Platform as a multi-tenant service. Your access is provisioned as an isolated sub-account. Other sub-accounts on the Platform are independent customers of OpSynx AI; you have no rights in, and no relationship with, any other sub-account. OpSynx AI may modify, enhance, or discontinue features of the Service from time to time, provided it does not materially reduce the core functionality for which you have paid during your then-current term.

3. Accounts, roles, and security

You are responsible for maintaining the confidentiality of your and your Users’ login credentials and for all activity that occurs under your account. You are responsible for provisioning and de-provisioning your Users at role-appropriate levels of access and for the acts and omissions of your Users as if they were your own. Multi-factor authentication is required. You will notify OpSynx AI promptly of any suspected or actual unauthorized access to or use of the Service.

4. License grant and restrictions

Subject to your compliance with this Agreement and payment of applicable fees, OpSynx AI grants you a limited, non-exclusive, non-transferable, non-sublicensable right, during the term, to access and use the Service and Platform Data solely for your own internal real-estate acquisition, underwriting, and disposition activities. You will not, and will not permit any User or third party to: (a) resell, sublicense, rent, lease, distribute, or provide the Service or Platform Data to any third party as a service bureau or otherwise; (b) reverse engineer, decompile, disassemble, or attempt to derive source code or underlying models, except to the extent this restriction is prohibited by law; (c) scrape, harvest, or bulk-extract Platform Data except through features expressly provided; (d) build a competing product or dataset using the Service or Platform Data; (e) remove or obscure proprietary notices; or (f) use the Service in violation of law or the Acceptable Use Policy.

5. Customer responsibility for outreach and compliance with law

You are solely and exclusively responsible for the legality of all outreach, marketing, and communications you conduct using or informed by the Service. This includes, without limitation, full compliance with the Telephone Consumer Protection Act (TCPA), the Telemarketing Sales Rule, state and federal Do-Not-Call registries and internal do-not-call obligations, calling-hour and frequency restrictions, caller-ID and identification requirements, wireless and SMS/text-messaging consent rules, email (CAN-SPAM) rules, fair-housing and fair-lending laws, and all applicable state and local statutes. You are solely responsible for obtaining any required consent and for having an independent lawful basis to contact any lead or owner. OpSynx AI does not provide consent, does not verify Do-Not-Call status, and does not place calls or send messages on your behalf. You bear all risk and liability arising from your outreach.

6. Platform Data and skip-trace

Platform Data, comparable sales, ownership information, and skip-trace results are compiled from public records and third-party sources and are provided to assist you in evaluating the underlying property. Such data may be incomplete, out of date, or inaccurate. You may use Platform Data and skip-trace results only for your own lawful real-estate activity concerning the specific underlying property, and you may not resell, redistribute, or use them for any impermissible purpose (including any use governed by the Fair Credit Reporting Act, for which the data is not intended or authorized). OpSynx AI makes no representation or warranty as to the accuracy, completeness, currency, or fitness of any public-record or third-party data.

7. No professional advice; Output is an estimate only

The Service does not provide, and nothing in the Service constitutes, legal, financial, tax, accounting, appraisal, brokerage, or investment advice. All Output — including every valuation, comparable-sales figure, market or retail value, offer amount, offer ladder, spread, disposition price, score, and due-diligence result — is an automated ESTIMATE generated by software. Output is not an appraisal, is not prepared by a licensed appraiser, does not comply with USPAP, and is not a guarantee, promise, or assurance of value, marketability, title, condition, or outcome. Output is not a substitute for your own independent verification, inspection, title work, survey, environmental review, and professional counsel. You make every offer, purchase, sale, and business decision at your own risk and based on your own independent judgment. OpSynx AI is not a party to any transaction and is not liable for any lost, mispriced, or failed deal, or for any decision or outcome resulting from your use of the Service or Output.

8. Fees, billing, and taxes

You will pay all fees stated on your Order Form, which may include setup and onboarding fees, recurring subscription fees, infrastructure pass-through charges, and usage-based data (including skip-trace) fees. Subscription fees are billed in advance and, except as expressly stated in the Refund and Cancellation Policy, are non-refundable. Usage-based and third-party pass-through costs are non-refundable once incurred. Fees are exclusive of taxes, which you are responsible for (other than taxes on OpSynx AI’s net income). Past-due amounts may accrue interest at the lesser of 1.5% per month or the maximum permitted by law, and OpSynx AI may suspend the Service for non-payment after notice.

9. Intellectual property

As between the parties, OpSynx AI and its licensors own all right, title, and interest in and to the Service, the Platform, the software, the models, the Platform Data (excluding your Customer Data), and all improvements, and all intellectual-property rights therein. You own your Customer Data. You grant OpSynx AI a worldwide, non-exclusive license to host, process, and use Customer Data solely to provide, secure, and support the Service. OpSynx AI may collect and use aggregated and de-identified usage data that does not identify you or any individual to operate, analyze, and improve the Service.

10. Confidentiality

Each party (as receiving party) will protect the other party’s non-public information disclosed in connection with this Agreement using at least reasonable care, will use it only to perform under this Agreement, and will not disclose it except to personnel and advisors bound by comparable obligations. This section does not apply to information that is public through no fault of the receiving party, independently developed, or rightfully received from a third party.

11. Warranty disclaimer

THE SERVICE, THE PLATFORM DATA, AND ALL OUTPUT ARE PROVIDED “AS IS” AND “AS AVAILABLE,” WITH ALL FAULTS, AND WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, WHETHER EXPRESS, IMPLIED, OR STATUTORY. TO THE MAXIMUM EXTENT PERMITTED BY LAW, OPSYNX AI EXPRESSLY DISCLAIMS ALL WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, NON-INFRINGEMENT, ACCURACY, AND ANY WARRANTY ARISING FROM COURSE OF DEALING OR USAGE OF TRADE. OPSYNX AI DOES NOT WARRANT THAT THE SERVICE WILL BE UNINTERRUPTED, ERROR-FREE, OR SECURE, OR THAT ANY DATA OR OUTPUT WILL BE ACCURATE OR COMPLETE.

12. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, NEITHER PARTY WILL BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR FOR ANY LOST PROFITS, LOST REVENUE, LOST OR MISPRICED DEALS, LOST BUSINESS OPPORTUNITIES, OR LOSS OF DATA OR GOODWILL, ARISING OUT OF OR RELATED TO THIS AGREEMENT OR THE SERVICE, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. OPSYNX AI’S TOTAL AGGREGATE LIABILITY ARISING OUT OF OR RELATED TO THIS AGREEMENT OR THE SERVICE WILL NOT EXCEED THE TOTAL FEES ACTUALLY PAID BY YOU TO OPSYNX AI IN THE THREE (3) MONTHS IMMEDIATELY PRECEDING THE EVENT GIVING RISE TO THE CLAIM. THESE LIMITATIONS APPLY REGARDLESS OF THE THEORY OF LIABILITY AND FORM AN ESSENTIAL BASIS OF THE BARGAIN.

13. Indemnification

You will defend, indemnify, and hold harmless OpSynx AI and its officers, directors, employees, and agents from and against any and all third-party claims, damages, liabilities, losses, fines, penalties, and expenses (including reasonable attorneys’ fees) arising out of or related to: (a) your Customer Data; (b) your outreach, marketing, calls, or messages, including any TCPA, Do-Not-Call, telemarketing, consumer-protection, or fair-housing claim; (c) any offer you make or transaction you enter; (d) your use of the Service or Output; or (e) your violation of this Agreement, the Acceptable Use Policy, or any law.

14. Term, suspension, and termination

This Agreement begins on your first acceptance or access and continues for the term stated on your Order Form, renewing as set out there. Either party may terminate for the other party’s material breach not cured within thirty (30) days of written notice. OpSynx AI may suspend or limit the Service immediately to address a security risk, a violation of the Acceptable Use Policy, non-payment, or a legal requirement. On termination, your right to use the Service ceases; OpSynx AI will make your Customer Data available for export for a limited period, after which it will be deleted in accordance with the Data Processing and Data-Sharing Addendum. Sections that by their nature should survive (including fees accrued, IP, confidentiality, disclaimers, limitation of liability, indemnification, and governing law) survive termination.

15. Governing law and venue

This Agreement is governed by the laws of the State of Florida, without regard to its conflict-of-laws rules and excluding the U.N. Convention on Contracts for the International Sale of Goods. The exclusive venue for any dispute is the state and federal courts located in Florida, and each party consents to personal jurisdiction there.

16. Changes to these Terms

OpSynx AI may update this Agreement from time to time. For material changes, OpSynx AI will provide reasonable notice (for example, in-app or by email) and may require re-acceptance. Your continued use of the Service after the effective date of an update constitutes acceptance of the updated Terms.

17. General

This Agreement, together with any Order Form and the policies referenced herein, is the entire agreement between the parties on its subject matter. If any provision is held unenforceable, the remainder remains in effect. Neither party may assign this Agreement without the other’s consent, except to a successor in a merger or sale of substantially all assets. Failure to enforce a provision is not a waiver.
