Terms of Use

Last updated: October 7, 2026

Welcome to Mesonsoft. These Terms of Use (“Terms”) govern access to and use of the websites, software, platforms, AI systems, APIs, and professional services offered by Mesonsoft (“Mesonsoft,” “we,” “us,” or “our”). By accessing or using any of our services, you agree to these Terms and our Privacy Policy. If you do not agree, do not use the services.

1. Scope and Contract Structure

These Terms apply to all users unless superseded by a signed master services agreement, statement of work, order form, enterprise agreement, or data processing agreement. If there is a conflict, the signed agreement controls for the services covered by that agreement.

2. Eligibility and Authority

You must be at least 18 years old and legally capable of entering into a binding contract. If you access or use services for a company or other entity, you represent and warrant that you are authorized to bind that entity, and references to “you” include that entity.

3. Account Security and Credentials

You are responsible for all activity under your accounts, API keys, tokens, and credentials. You must maintain reasonable security controls, promptly rotate compromised credentials, and immediately notify us of unauthorized access or suspected security incidents.

4. Acceptable Use and Prohibited Conduct

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

• Use the services in violation of applicable law, regulation, sanctions, export controls, or court order;
• Use the services for unlawful surveillance, social scoring, discriminatory profiling, election manipulation, harassment, deepfake fraud, malware generation, or other harmful activity;
• Submit data you do not have a legal right to process, including personal data, protected health data, confidential information, or trade secrets without required permissions;
• Bypass or attempt to bypass security, safety, moderation, monitoring, or rate-limiting controls;
• Probe, scan, reverse engineer, decompile, or attempt to derive model weights, prompts, system instructions, or proprietary architecture;
• Use outputs or service telemetry to train or improve a competing model or service, except where expressly permitted in writing;
• Interfere with service performance, availability, or integrity, including abuse of compute, scraping, or denial-of-service behavior.

5. AI Systems, Outputs, and Decision Risk

AI and machine learning outputs are probabilistic and may be incorrect, incomplete, biased, stale, non-unique, or inappropriate for your context. You are solely responsible for evaluating outputs before use, adding human review, and determining whether outputs are fit for your use case.

Not professional advice: Outputs are not legal, medical, accounting, financial, employment, safety, or other professional advice. You must not rely on outputs as the sole basis for high-impact decisions affecting legal rights, employment, housing, education, healthcare, lending, insurance, or public safety.

6. Your Compliance Obligations for AI

You are responsible for determining and meeting your own compliance obligations, including impact assessments, transparency notices, human oversight, recordkeeping, and risk controls required by law (for example, where applicable, under AI, privacy, consumer protection, or sector-specific regulation).

7. Customer Content and Usage Rights

You retain ownership of content, prompts, files, and data you submit to the services (“Customer Content”). You grant Mesonsoft a limited, non-exclusive, worldwide, royalty-free license to host, process, transmit, and use Customer Content solely as necessary to provide, secure, maintain, and support the services, and as otherwise permitted by contract or law.

You represent and warrant that you have all rights and lawful bases required to provide Customer Content and to instruct us to process it.

8. Mesonsoft Intellectual Property

Mesonsoft and its licensors retain all rights, title, and interest in and to the services, including software, models, orchestration logic, workflows, interfaces, know-how, documentation, trademarks, and all related intellectual property rights. No rights are granted except as expressly stated in these Terms.

9. Third-Party Models and Services

Services may rely on third-party providers (including cloud hosts, foundation model providers, and integrations). We may add, remove, or replace providers at our discretion. Third-party services are governed by their own terms and policies, and Mesonsoft is not responsible for third-party acts, omissions, outages, or model behavior.

10. Security and Incident Response

We implement administrative, technical, and organizational safeguards appropriate to the nature of the services. No system is perfectly secure. You acknowledge residual security risk and agree to cooperate with reasonable incident response steps, including suspension or containment actions when necessary to protect systems or users.

11. Confidentiality

Each party may receive non-public information from the other party. The receiving party will use such confidential information only to perform or receive services and will protect it with reasonable care. These obligations do not apply to information that is public through no fault of the receiving party, independently developed, or lawfully received from a third party without duty of confidentiality.

12. Disclaimers

TO THE MAXIMUM EXTENT PERMITTED BY LAW, THE SERVICES AND OUTPUTS ARE PROVIDED “AS IS” AND “AS AVAILABLE.” MESONSOFT DISCLAIMS ALL WARRANTIES, EXPRESS, IMPLIED, STATUTORY, OR OTHERWISE, INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, NON-INFRINGEMENT, AVAILABILITY, SECURITY, ACCURACY, AND ERROR-FREE OPERATION. MESONSOFT DOES NOT WARRANT THAT OUTPUTS WILL BE CORRECT, UNIQUE, OR SUITABLE FOR YOUR NEEDS.

13. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, MESONSOFT WILL NOT BE LIABLE FOR INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR FOR LOST PROFITS, LOST REVENUE, LOSS OF DATA, LOSS OF BUSINESS OPPORTUNITY, OR REPUTATIONAL HARM, ARISING FROM OR RELATED TO THE SERVICES OR OUTPUTS, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

MESONSOFT’S AGGREGATE LIABILITY FOR ALL CLAIMS ARISING OUT OF OR RELATED TO THE SERVICES WILL NOT EXCEED THE TOTAL FEES YOU PAID TO MESONSOFT FOR THE APPLICABLE SERVICE IN THE TWELVE (12) MONTHS BEFORE THE EVENT GIVING RISE TO LIABILITY.

14. Indemnification

You will defend, indemnify, and hold harmless Mesonsoft, its affiliates, and their officers, directors, employees, and agents from and against claims, liabilities, losses, damages, judgments, penalties, costs, and expenses (including reasonable attorneys’ fees) arising out of or related to: (a) your Customer Content; (b) your use of services or outputs; (c) your violation of these Terms or applicable law; or (d) your products or services that incorporate or depend on outputs.

15. Suspension and Termination

We may suspend, restrict, or terminate access immediately if we reasonably believe there is a security risk, legal violation, policy breach, fraud, abuse, or risk of harm. You may stop using services at any time. Sections that by their nature should survive termination will survive, including sections on intellectual property, disclaimers, limitation of liability, indemnification, confidentiality, and dispute terms.

16. Changes to Services and Terms

We may modify, discontinue, or update services and these Terms. We will post revised Terms with an updated date. Your continued use after the effective date constitutes acceptance of the revised Terms.

17. Governing Law and Venue

These Terms are governed by the laws of the Commonwealth of Virginia, excluding its conflict-of-law rules. Unless otherwise required by applicable law, exclusive venue for disputes will be in state or federal courts located in Virginia, and you consent to personal jurisdiction in those courts.
