Terms of Service

Last updated September 19, 2026

These Terms of Service ("Terms") are a legally binding agreement between you and Verttx Solutions LLC, a Washington limited liability company ("Verttx," "we," "us," or "our"). They govern your access to and use of the Verttx website, web application, mobile applications, and related services (collectively, the "Services").

By creating an account or using the Services, you agree to these Terms, our Usage Policy, and our Privacy Policy. If you do not agree, do not use the Services.

These Terms contain a binding arbitration agreement and class action waiver (Section 18) that affect how disputes are resolved. You can opt out within 30 days of accepting these Terms (Section 18.7). If you are a consumer in the European Economic Area, the United Kingdom, or Switzerland, Section 18 does not apply to you — see Section 19.

Summary

This summary is for convenience only; the full Terms below control.

What VERTTX is: role-based AI assistants for your business. They draft, analyze, and advise using an AI model — and AI can be wrong. You are responsible for reviewing every output before you rely on it or publish it.
Your content is yours. You own what you upload and what your assistants produce. We use your content only to run the Services for you. We do not use your content to train AI models, and neither does our AI provider.
Billing: paid plans renew automatically until you cancel. Cancel any time; access continues until the end of the period you paid for. Upgrades take effect immediately; downgrades at the next renewal.
Not professional advice. Nothing an assistant produces is legal, tax, accounting, financial, or other licensed professional advice.
Play fair. Our Usage Policy explains what you can't do. Every plan has usage limits, explained on our Usage Limits page.
Disputes: most disputes go to individual arbitration, with a 30-day opt-out and carve-outs for small claims and for consumers in the EU/UK.

1. Eligibility

You must be at least 18 years old (or the age of majority where you live, if higher) to use the Services. By using the Services, you represent that:

You are at least 18 years of age and have the legal capacity to enter into a binding contract;
You are not barred from using the Services under applicable law, and you are not on any U.S. government list of prohibited or restricted parties;
You are not located in a country subject to a comprehensive U.S. government embargo.

The Services are built for professional and business use. If you use the Services on behalf of a company or other organization, you represent that you have authority to bind that organization to these Terms, and "you" includes that organization. If you use an account your employer provides or pays for, your employer may be able to access and control that account.

2. The Services

Verttx provides AI-powered assistants built for specific professional roles (for example sales, marketing, social media, accounting, and founder operations), and — where your plan includes it — custom roles you define. Each assistant is configured with the business context, answers, and files you provide, and generates responses in conversation with you. Depending on your plan, the Services may also search the web to answer questions with current information, and generate downloadable documents.

The Services generate responses using third-party artificial intelligence models — currently Claude, provided by Anthropic, PBC ("Anthropic"). We may add, replace, or remove AI providers as the Services evolve; the Privacy Policy lists the providers in use.

We are continuously improving the Services. We may add, change, or remove features, and we may modify, suspend, or discontinue all or part of the Services. Where a change materially reduces the core functionality of a paid plan, we will give you reasonable advance notice (by email or in the Services), and you may cancel under Section 4.7.

3. Your Account

To use the Services, you must create an account with an email address and password, or through a supported sign-in provider (currently Google and Apple). You agree to:

Provide accurate, current, and complete information and keep it up to date;
Keep your credentials confidential and not share your account with anyone else;
Notify us promptly at contact@verttx.ai if you suspect unauthorized access to your account;
Accept responsibility for all activity that occurs under your account.

Each account is for one person. You may not transfer your account, create an account using someone else's identity, or create multiple accounts to circumvent trial limits, usage limits, or a suspension.

4. Plans, Billing, and Cancellation

4.1 Plans and pricing

The Services are offered through subscription plans, described on our website and in Settings → Billing. Each plan includes a set number of assistants, a monthly usage allowance, file limits, and features. Our Usage Limits page explains how usage is measured and when it resets. We may change plan features and prices; price changes for an existing subscription take effect no earlier than 30 days after we notify you, and never before your next renewal.

4.2 Free trial

New accounts start with a free trial that lets you use the Services without payment information. The trial ends after seven (7) days or once you have used the trial's included usage, whichever comes first. At the end of the trial your assistants, files, and conversations are kept, but you must subscribe to a paid plan to keep sending messages. We may change or discontinue the trial at any time, and we may limit trials to one per person or business.

4.3 Billing and auto-renewal

Paid plans are billed in advance on a recurring monthly or annual basis, depending on the billing cycle you choose, through our payment processor, Stripe, Inc. ("Stripe"). By providing a payment method you authorize us (through Stripe) to charge it for the plan price, applicable taxes, and any prorated amounts under Section 4.4, at the start of each billing period. Your subscription renews automatically at the end of each billing period at the then-current price for your plan until you cancel. You are responsible for keeping your payment information current.

Subscriptions are sold and managed only through our website. Our mobile apps do not sell subscriptions, and no purchases are made through Apple's App Store or Google Play.

4.4 Plan changes

You may change plans at any time in Settings → Billing. Upgrades take effect immediately; you are charged a prorated amount for the remainder of the current billing period, and the new price applies from the next renewal. Downgrades are scheduled to take effect at the end of the current billing period, and you keep your current plan's features until then. When a downgrade takes effect, anything above the new plan's limits (for example additional assistants or files) may become read-only until you remove enough to fit the new plan.

4.5 Failed payments

If a renewal payment fails, we will retry it and notify you. You keep full access for a grace period of seven (7) days after the failed payment. After that, your account becomes read-only — your assistants, files, and conversations remain available to view and export, but you cannot send new messages — until payment succeeds. If payment is not resolved, we may cancel the subscription.

4.6 Taxes

Prices exclude taxes. You are responsible for any sales, use, value-added, goods and services, or similar taxes that apply to your purchase, except taxes based on our net income. Where we are required to collect tax, it will be added to your invoice.

4.7 Cancellation

You may cancel your subscription at any time in Settings → Billing. Cancellation takes effect at the end of the billing period you have already paid for; you keep full access until then, and you will not be charged again. You can resume a canceled subscription before the period ends. Your assistants, files, and conversation history are not deleted when you cancel — you can delete them, or your account, at any time from Settings → Privacy & data.

4.8 Refunds

Except as described in this Section 4.8 or required by law, payments are non-refundable and we do not provide refunds or credits for partial billing periods, unused usage, or downgrades. If you believe you were charged in error, contact contact@verttx.ai with your account email and the details.

If you are a consumer in the European Economic Area, the United Kingdom, or Switzerland, you have a statutory right to withdraw from a paid subscription within fourteen (14) days of purchase without giving a reason. By subscribing, you ask us to begin providing the Services immediately. If you withdraw within the 14-day period, we will refund the amount you paid less a proportionate amount for the period during which you had access to the Services. To withdraw, email contact@verttx.ai from your account email with a clear statement that you are withdrawing.

5. Usage Limits and Fair Use

Every plan includes a usage allowance, described qualitatively on our pricing pages and explained in detail on our Usage Limits page, which is part of these Terms. When you reach your plan's allowance, you can upgrade or wait for the allowance to reset at the start of your next period — nothing is deleted. Setting up assistants, uploading files, and editing what an assistant knows do not count toward usage.

The Services are designed for genuine professional use by a person or business. To keep the Services reliable for everyone, we may apply reasonable fair-use limits, and we may throttle, rate-limit, or suspend accounts that use the Services in an automated, bulk, or resale-scale manner, share a single account among multiple people, or otherwise use the Services in a way that is inconsistent with their intended purpose. We will contact you before taking action where practical.

6. Acceptable Use

You must use the Services in accordance with our Usage Policy, which is part of these Terms. In short, you agree not to use the Services to:

Violate any law or regulation, or the rights of any person;
Generate or distribute content that is unlawful, defamatory, fraudulent, deceptive, harassing, hateful, or that promotes violence or self-harm;
Generate sexually explicit content, or any content that sexualizes or endangers minors;
Develop weapons, malware, or attacks on people, systems, or infrastructure;
Infringe or misappropriate anyone's intellectual property, privacy, or publicity rights;
Deceive people — for example by impersonating a person or organization, generating fake reviews or testimonials, fabricating statistics or credentials, or presenting AI-generated content as human-authored where that is misleading or prohibited by law;
Make decisions that have legal or similarly significant effects on people (such as employment, credit, insurance, housing, or medical decisions) based solely on AI output without qualified human review;
Probe, scan, or test the vulnerability of the Services, bypass authentication or usage limits, or access data that is not yours;
Reverse engineer the Services, extract our prompts or configurations, or attempt to bypass the AI model's safety measures ("jailbreaking");
Use automated tools to access the Services, or use the Services or their output to develop or train a competing product or an AI model;
Resell, sublicense, or provide the Services to third parties as a service.

We may investigate suspected violations and, where we reasonably believe a violation has occurred, remove content, throttle, suspend, or terminate accounts, and (where the law requires or permits) report activity to law enforcement. Because the Services run on a third-party AI model, its provider's usage policy also applies to how the model may be used; the Usage Policy explains this.

7. Your Content

7.1 Definition

"Your Content" means everything you provide to the Services — messages, prompts, business details and answers you give when setting up an assistant, files, images, and other attachments — and the responses and documents the Services generate for you ("Output").

7.2 Ownership

You own Your Content. As between you and Verttx, you retain all rights in the content you provide, and we assign to you all of our right, title, and interest, if any, in the Output generated for you. You may use Output for any lawful purpose, including commercially, subject to these Terms.

Because AI models generate responses from patterns, Output may not be unique: other users may receive similar or identical Output from similar inputs, and Output is not "yours" to the extent it is the same as Output provided to another user. AI-generated content may also have limited or no copyright protection in some jurisdictions.

7.3 License to us

So that we can run the Services, you grant Verttx a worldwide, non-exclusive, royalty-free license to host, store, process, transmit, reproduce, and display Your Content solely to provide, secure, support, and maintain the Services for you, and as required by law. This includes sending Your Content to our AI provider to generate responses, and to our infrastructure providers to store it. This license ends when you delete the content or your account, except for copies in routine backups (which expire on their normal schedule) and copies we must keep to comply with law.

We do not use Your Content to train or improve AI models, and our AI provider is contractually prohibited from using it to train its models. We will not change this without notifying you in advance and giving you a choice.

7.4 Your responsibilities

You are responsible for Your Content. You represent that you have all rights and permissions needed to provide it to the Services, including any personal data about your customers, employees, or other people it contains, and that it does not violate any law or third-party right. Do not upload content you are not permitted to share, such as information subject to a confidentiality obligation you cannot honor, or export-controlled data.

Your Content is private to your account. The Services have no public sharing or publishing features; nothing you create is visible to other users.

7.5 Customer data you upload

If Your Content includes personal data about other people (for example a customer list or correspondence), you are the data controller (or equivalent) for that data and we process it on your behalf and on your instructions, as described in our Privacy Policy. You are responsible for having a lawful basis to provide it to us and for honoring the rights of the people it concerns. If you need a data processing agreement, contact contact@verttx.ai.

7.6 Feedback

If you rate a response or report a problem, we may review the conversation involved to investigate and improve the Services. If you send us suggestions or ideas about the Services ("Feedback"), you grant us a perpetual, irrevocable, worldwide, royalty-free license to use it for any purpose without obligation to you.

8. AI Output — Important Limitations

THE SERVICES USE ARTIFICIAL INTELLIGENCE TO GENERATE OUTPUT. OUTPUT MAY BE INACCURATE, INCOMPLETE, OUTDATED, BIASED, OR INAPPROPRIATE FOR YOUR SITUATION, AND MAY NOT REFLECT CURRENT LAW, RATES, FACTS, OR EVENTS.

You acknowledge and agree that:

AI models generate responses probabilistically and can produce confident-sounding errors, including invented facts, figures, quotations, citations, and sources ("hallucinations").
Output is not reviewed by a human before it is delivered to you. You are solely responsible for reviewing, verifying, and editing all Output before you rely on it, act on it, send it, publish it, or file it. Do not rely on Output as your sole source of truth.
Where an assistant searches the web, the results and citations come from third-party websites we do not control. They may be inaccurate, incomplete, out of date, or subject to those sites' own terms.
Where an assistant generates a document, spreadsheet, or other file, the same limitations apply to its contents, including any calculations.
Output is not professional advice. The Services are not a law firm, accounting or tax practice, financial adviser, or other licensed professional, and using them does not create an attorney-client, accountant-client, fiduciary, or similar relationship. Any figures, calculations, rates, or deadlines an assistant provides are illustrative and based on stated assumptions; they are not filing-ready and must be verified by a qualified professional or authoritative source before you use them. You are responsible for engaging qualified professionals where the stakes call for it.
You are responsible for ensuring that your use of Output complies with the laws that apply to you, including advertising, consumer protection, marketing, privacy, employment, and AI-transparency laws, and for making any required disclosures to your own audience that content was AI-generated.

9. Beta and Experimental Features

We may offer features labeled beta, preview, experimental, or similar ("Beta Features") — for example custom roles. Beta Features are provided for evaluation, may be less reliable than the rest of the Services, may change or be withdrawn at any time without notice, and may be subject to additional terms we present when you enable them. Beta Features are provided "as is," without warranties of any kind, and are excluded from any service commitments. We may collect feedback on Beta Features to improve them.

10. Intellectual Property

10.1 Our property

The Services — including all software, design, text, graphics, logos, role configurations, prompts, and documentation, but excluding Your Content — are owned by Verttx or its licensors and protected by intellectual property laws. Subject to these Terms, we grant you a limited, non-exclusive, non-transferable, non-sublicensable, revocable license to access and use the Services for your internal business purposes. All rights not expressly granted are reserved.

10.2 Trademarks

"Verttx," "VERTTX," and the Verttx logo are trademarks of Verttx Solutions LLC. You may not use them without our prior written permission.

10.3 Copyright complaints

We respect the intellectual property of others and respond to notices of alleged infringement that comply with the U.S. Digital Millennium Copyright Act (DMCA) and similar laws. If you believe content available through the Services infringes your copyright, send a notice to contact@verttx.ai with the subject line "Copyright Notice" that includes: (a) your physical or electronic signature; (b) identification of the copyrighted work you claim has been infringed; (c) identification of the material you claim is infringing and enough information for us to locate it; (d) your contact information; (e) a statement that you have a good-faith belief that the use is not authorized by the copyright owner, its agent, or the law; and (f) a statement, under penalty of perjury, that the information in the notice is accurate and that you are the copyright owner or authorized to act on the owner's behalf. We may terminate the accounts of repeat infringers.

11. Third-Party Services

The Services rely on third-party providers, including our AI provider (Anthropic), payment processor (Stripe), authentication and infrastructure providers (Supabase, Google, Apple), hosting providers (Vercel, Railway), and email, error-monitoring, and analytics providers. The Privacy Policy lists them. We may add, replace, or remove providers at any time. Third-party services are subject to their own terms; we are not responsible for their acts or omissions except as required by law.

Output may include links to, or content from, third-party websites. We do not control and are not responsible for those sites.

12. Mobile Applications

Our iOS and Android apps are licensed to you, not sold, under these Terms. The apps are a way to use the Services; subscriptions are purchased and managed only on our website (Section 4.3).

If you download an app from Apple's App Store or Google Play, the following also apply to the extent required by that store:

These Terms are between you and Verttx only, not with Apple Inc. or Google LLC (each an "App Distributor"). Verttx, not the App Distributor, is solely responsible for the app and its content, and for any maintenance and support.
The App Distributor has no obligation to provide any maintenance or support for the app, and no warranty obligation. To the maximum extent permitted by law, the App Distributor has no other warranty obligation with respect to the app; any other claims, losses, liabilities, damages, costs, or expenses attributable to a failure to conform to a warranty are our responsibility.
Verttx, not the App Distributor, is responsible for addressing any claims relating to the app or your use of it, including product liability claims, claims that the app fails to conform to legal or regulatory requirements, and consumer-protection or similar claims.
Verttx, not the App Distributor, is responsible for investigating, defending, settling, and discharging any third-party claim that the app infringes intellectual property rights.
You represent that you are not located in a country subject to a U.S. government embargo or designated as "terrorist supporting," and that you are not on any U.S. government list of prohibited or restricted parties.
The App Distributor and its subsidiaries are third-party beneficiaries of these Terms with respect to the app and may enforce them against you.
Your use of the app must also comply with the App Distributor's applicable terms of service.

13. Termination

13.1 By you

You may stop using the Services at any time. You may cancel your subscription (Section 4.7) and delete your account from Settings → Privacy & data, or by emailing contact@verttx.ai. Deleting your account is permanent; export your data first if you want to keep it.

13.2 By us

We may suspend or terminate your account or access to the Services:

Immediately, if you materially breach these Terms or the Usage Policy, if we reasonably believe your use creates risk or legal exposure for us or others, if required by law, or if your subscription payment remains unresolved after the grace period in Section 4.5;
With at least thirty (30) days' notice, for any other reason, including if we discontinue the Services;
With at least thirty (30) days' notice, if your account has had no paid subscription and has been inactive for twelve (12) consecutive months, in which case we may delete the account and its data.

Where practical, we will tell you the reason for a suspension or termination, and you may contact contact@verttx.ai to ask us to reconsider.

13.3 Effect

When your account ends, your right to use the Services ends and we will delete Your Content as described in the Privacy Policy. Sections 4.8, 7, 8, 10, 14, 15, 16, 18, 19, and 20, and any other provisions that by their nature should survive, survive termination.

14. Disclaimers

EXCEPT AS EXPRESSLY STATED IN THESE TERMS, AND TO THE MAXIMUM EXTENT PERMITTED BY LAW, THE SERVICES AND ALL OUTPUT ARE PROVIDED "AS IS" AND "AS AVAILABLE," WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS, IMPLIED, OR STATUTORY, INCLUDING WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, NON-INFRINGEMENT, ACCURACY, AND ANY WARRANTIES ARISING FROM COURSE OF DEALING OR USAGE OF TRADE.

WE DO NOT WARRANT THAT THE SERVICES WILL BE UNINTERRUPTED, TIMELY, SECURE, OR ERROR-FREE; THAT OUTPUT WILL BE ACCURATE, COMPLETE, RELIABLE, OR SUITABLE FOR ANY PURPOSE; THAT DEFECTS WILL BE CORRECTED; OR THAT THE SERVICES ARE FREE OF VIRUSES OR OTHER HARMFUL COMPONENTS. YOU USE THE SERVICES AND OUTPUT AT YOUR OWN RISK.

Some jurisdictions do not allow the exclusion of certain warranties, so some of the above may not apply to you. If you are a consumer, nothing in these Terms affects statutory rights that cannot be waived.

15. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, VERTTX AND ITS AFFILIATES, AND THEIR OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, SUPPLIERS, AND LICENSORS, WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF PROFITS, REVENUE, BUSINESS, GOODWILL, DATA, OR OPPORTUNITY, ARISING OUT OF OR RELATING TO THESE TERMS, THE SERVICES, OR ANY OUTPUT — INCLUDING YOUR USE OF OR RELIANCE ON OUTPUT — HOWEVER CAUSED AND UNDER ANY THEORY OF LIABILITY, EVEN IF WE HAVE BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

TO THE MAXIMUM EXTENT PERMITTED BY LAW, OUR TOTAL LIABILITY FOR ALL CLAIMS ARISING OUT OF OR RELATING TO THESE TERMS OR THE SERVICES WILL NOT EXCEED THE GREATER OF (A) THE AMOUNT YOU PAID US FOR THE SERVICES IN THE TWELVE (12) MONTHS BEFORE THE EVENT GIVING RISE TO THE CLAIM, OR (B) ONE HUNDRED U.S. DOLLARS (US $100).

These limitations do not exclude or limit liability for death or personal injury caused by negligence, for fraud or fraudulent misrepresentation, for gross negligence or willful misconduct, or for any other liability that cannot be excluded or limited under applicable law. Some jurisdictions do not allow the limitation of certain damages, so some of the above may not apply to you.

16. Indemnification

To the extent permitted by law, you will defend, indemnify, and hold harmless Verttx and its affiliates, and their officers, directors, employees, and agents, from and against any third-party claims, and any resulting damages, liabilities, costs, and expenses (including reasonable attorneys' fees), arising out of or relating to: (a) Your Content; (b) your use of the Services or Output, including any content you publish, send, or file that was generated with the Services; (c) your breach of these Terms or the Usage Policy; or (d) your violation of any law or the rights of any third party. We may assume the exclusive defense of any matter subject to indemnification, in which case you will cooperate with us. This Section does not apply to you to the extent you are a consumer in a jurisdiction where such indemnities are not enforceable against consumers.

17. Changes to These Terms

We may update these Terms from time to time. If we make a material change, we will notify you at least thirty (30) days before it takes effect, by email to your account address or by a prominent notice in the Services. Changes that are required by law, that address a new feature, or that are otherwise not materially adverse to you may take effect when posted. The "Last updated" date at the top reflects the current version. If you continue to use the Services after a change takes effect, you accept the updated Terms; if you do not agree, you must stop using the Services and may cancel under Section 4.7.

18. Dispute Resolution — Binding Arbitration and Class Action Waiver

PLEASE READ THIS SECTION CAREFULLY. IT REQUIRES MOST DISPUTES BETWEEN YOU AND VERTTX TO BE RESOLVED BY BINDING INDIVIDUAL ARBITRATION RATHER THAN IN COURT, AND WAIVES JURY TRIALS AND CLASS ACTIONS. THIS SECTION DOES NOT APPLY TO CONSUMERS IN THE EUROPEAN ECONOMIC AREA, THE UNITED KINGDOM, OR SWITZERLAND (SEE SECTION 19).

18.1 Informal resolution first

Before starting arbitration or any court proceeding, the party raising the dispute must send the other a written notice describing the dispute and the relief requested (to us: contact@verttx.ai with the subject line "Dispute Notice"; to you: your account email). You and we agree to try in good faith to resolve the dispute informally for sixty (60) days after the notice is received, including by a phone or video conference if either party requests one. Any applicable limitation period is paused during this period. If the dispute is not resolved, either party may proceed under this Section.

18.2 Binding arbitration

Except for the disputes described in Section 18.5, any dispute, claim, or controversy arising out of or relating to these Terms, the Services, or Output ("Dispute") will be resolved exclusively by final and binding arbitration administered by the American Arbitration Association ("AAA") under its Consumer Arbitration Rules (or, if you are not a consumer, its Commercial Arbitration Rules) then in effect, as modified by this Section. The rules are available at www.adr.org. The Federal Arbitration Act governs the interpretation and enforcement of this Section.

The arbitration will be conducted by a single neutral arbitrator, in English. Hearings, if any, will be held by video conference unless the arbitrator decides an in-person hearing is necessary, in which case it will be in King County, Washington, or a location reasonably convenient to you. The arbitrator has exclusive authority to resolve any dispute about the interpretation, applicability, or enforceability of this Section, except that a court decides whether Section 18.4 is enforceable. The arbitrator may award the same relief a court could award to an individual party, and must follow these Terms. Judgment on the award may be entered in any court with jurisdiction.

18.3 Fees

Arbitration fees are governed by the AAA rules. For claims by a consumer, if the value of the relief you seek is US $10,000 or less, we will pay all AAA filing, administration, and arbitrator fees (other than fees the arbitrator finds you incurred in bad faith), unless the arbitrator finds your claim frivolous. Each party bears its own attorneys' fees unless the arbitrator awards them under applicable law.

18.4 Class action and jury trial waiver

YOU AND VERTTX AGREE THAT EACH MAY BRING CLAIMS AGAINST THE OTHER ONLY IN AN INDIVIDUAL CAPACITY, AND NOT AS A PLAINTIFF OR CLASS MEMBER IN ANY PURPORTED CLASS, COLLECTIVE, CONSOLIDATED, OR REPRESENTATIVE PROCEEDING. THE ARBITRATOR MAY NOT CONSOLIDATE MORE THAN ONE PERSON'S CLAIMS OR PRESIDE OVER ANY FORM OF REPRESENTATIVE OR CLASS PROCEEDING. YOU AND VERTTX ALSO WAIVE ANY RIGHT TO A JURY TRIAL. If this Section 18.4 is found unenforceable as to a particular claim or request for relief, that claim or request will be severed and decided in court, and the remainder proceeds in arbitration.

18.5 Exceptions

Either party may (a) bring an individual claim in small claims court if it qualifies; (b) seek injunctive or other equitable relief in court to stop unauthorized use or abuse of the Services or infringement of intellectual property rights; and (c) bring claims that cannot be arbitrated under applicable law.

18.6 Coordinated filings

If twenty-five (25) or more similar demands for arbitration are filed against Verttx by the same or coordinated counsel, the parties agree that the AAA's Mass Arbitration Supplementary Rules (or, if unavailable, a comparable procedure the parties agree to) will apply, that the demands will be resolved in staged batches, and that any applicable limitation period is paused while a demand awaits its batch. A court may enforce this Section 18.6.

18.7 Opt-out

You may opt out of Sections 18.2 through 18.6 by emailing contact@verttx.ai within thirty (30) days after you first accept these Terms, with the subject line "Arbitration Opt-Out" and your name, the email address on your account, and a clear statement that you opt out of arbitration. Opting out does not affect any other part of these Terms. If you opt out, Disputes will be resolved in the courts described in Section 19.

18.8 Changes to this Section

If we change this Section 18 after you accept these Terms, you may reject the change by emailing contact@verttx.ai within thirty (30) days of the change taking effect, in which case the version of this Section you most recently accepted will apply to Disputes that arose before the change.

19. Governing Law and Venue

These Terms and any Dispute are governed by the laws of the State of Washington, United States, and applicable U.S. federal law, without regard to conflict-of-laws principles. Subject to Section 18, any court proceeding will be brought exclusively in the state or federal courts located in King County, Washington, and you and we consent to their personal jurisdiction. The United Nations Convention on Contracts for the International Sale of Goods does not apply.

If you are a consumer in the European Economic Area, the United Kingdom, or Switzerland: Section 18 does not apply to you. You may bring proceedings in the courts of the country where you live, and you benefit from any mandatory provisions of the consumer-protection law of that country. The European Commission's online dispute resolution platform is available at ec.europa.eu/consumers/odr; we are not obliged and do not commit to participate in alternative dispute resolution proceedings before a consumer arbitration body.

20. Export Controls and Sanctions

You must comply with all applicable U.S. and international export control and sanctions laws. You may not use, export, re-export, or transfer the Services or any Output in violation of those laws, and you represent that you are not located in, or ordinarily resident in, a country or region subject to comprehensive U.S. sanctions, and are not on any government list of prohibited or restricted parties.

21. General

21.1 Entire agreement

These Terms, together with the Usage Policy, the Usage Limits page, the Privacy Policy, and any additional terms we present for specific features, are the entire agreement between you and Verttx regarding the Services and supersede all prior agreements and understandings on that subject.

21.2 Severability

If any provision of these Terms is held invalid or unenforceable, it will be enforced to the maximum extent permitted and the remaining provisions remain in full force, except as provided in Section 18.4.

21.3 No waiver

Our failure to enforce any provision is not a waiver of our right to do so later. Any waiver must be in writing.

21.4 Assignment

You may not assign or transfer these Terms or your account without our prior written consent. We may assign these Terms to an affiliate or in connection with a merger, acquisition, reorganization, or sale of assets, and will notify you of any such assignment.

21.5 Notices and electronic communications

You consent to receive communications from us electronically, including by email to your account address and by notices in the Services, and you agree that these satisfy any legal requirement that a communication be in writing. Notices to us must be sent to contact@verttx.ai. Keep your account email current.

21.6 Force majeure

We are not liable for any failure or delay caused by events beyond our reasonable control, including natural disasters, acts of government, war, terrorism, labor disputes, epidemics, internet or telecommunications failures, or failures of third-party providers (including AI-model providers).

21.7 Relationship of the parties

You and Verttx are independent contractors. These Terms do not create a partnership, joint venture, agency, fiduciary, or employment relationship.

21.8 Interpretation and language

Section headings are for convenience only. "Including" means "including without limitation." These Terms are written in English; any translation is provided for convenience, and the English version controls to the extent permitted by law.

21.9 Notice to California residents

Under California Civil Code §1789.3, California users are entitled to the following notice: the Services are provided by Verttx Solutions LLC (contact@verttx.ai). The Complaint Assistance Unit of the Division of Consumer Services of the California Department of Consumer Affairs may be contacted in writing at 1625 North Market Blvd., Suite N 112, Sacramento, CA 95834, or by telephone at (800) 952-5210.
