Terms of Service

Last updated: June 7, 2026

These Terms of Service (“Terms”) are a binding agreement between you (“you” or “Customer”) and Kat ADA LLC, a California limited liability company (“Kat ADA,” “we,” “us,” or “our”), governing your access to and use of the Kat ADA website, application, and services (together, the “Service”).

By checking the “I agree” box, creating an account, subscribing, or otherwise using the Service, you acknowledge that you have read, understood, and agree to be bound by these Terms and by our Privacy Policy, which is incorporated by reference. If you do not agree, do not use the Service. If you accept these Terms on behalf of a business, you represent that you are authorized to bind that business, and “you” refers to that business.

Sections 9 (Disclaimers), 10 (Limitation of Liability), 11 (Indemnification), 12 (Release), and 13 (Arbitration and Class-Action Waiver) limit our liability and affect how disputes are resolved. Please read them carefully.

1. The Service; not legal advice

Kat ADA is an accessibility monitoring and remediation service for Squarespace websites. We scan your site for accessibility issues, generate fixes, apply them for you through the contributor access you grant us to your Squarespace site, and produce reports documenting your ongoing, good-faith remediation effort.

KAT ADA IS NOT A LAW FIRM AND DOES NOT PROVIDE LEGAL ADVICE. THE SERVICE IS NOT A GUARANTEE OF COMPLIANCE WITH THE ADA, WCAG, SECTION 508, THE UNRUH ACT, OR ANY OTHER LAW, REGULATION, OR STANDARD, AND DOES NOT MAKE YOUR SITE “LAWSUIT-PROOF.” Automated testing detects only a portion of accessibility issues; human judgment and manual testing remain necessary. Web accessibility is an ongoing responsibility of the site owner. Reports we produce document a good-faith effort and are not certifications of conformance or legal compliance.

2. Eligibility and accounts

You must be at least 18 years old and able to form a binding contract. You agree to provide accurate, current information, to keep your sign-in secure, and to be responsible for all activity under your account. You must promptly notify us of any unauthorized use. We use passwordless email sign-in; you are responsible for maintaining access to, and the security of, the email account you use.

3. Your site, authorization, and your responsibilities

You represent and warrant that you own, or are fully authorized to manage and to grant access to, any website you connect to the Service. You authorize Kat ADA to (a) crawl and analyze your public pages, and (b) where you grant us contributor access to your Squarespace site, access your site and apply accessibility changes to it on your behalf. We do the work for you, so you do not need to approve each change individually; changes are reflected in the report we send you, and you may revoke our access at any time from your Squarespace settings.

You are responsible for: maintaining your own Squarespace account, plan, and credentials; maintaining your own backups of your site and content; the accuracy and legality of your site content; and any changes you or third parties make outside the Service. We are not responsible for loss of, or changes to, your site or content that result from your Squarespace account, third parties, or causes outside our reasonable control.

4. Your content; license to us

As between you and us, you retain all rights in your website and its content (“Customer Content”). You grant Kat ADA a limited, non-exclusive, worldwide, royalty-free license to access, copy, analyze, display, and modify your Customer Content solely to provide, secure, and improve the Service for you and to document the work performed. You also grant us permission to retain scan results, reports, and a record of changes for the purposes described in our Privacy Policy.

5. Our intellectual property; feedback

The Service, including our software, scanning and triage technology, report templates, and all related intellectual property, is and remains owned by Kat ADA and its licensors. Except for the limited right to use the Service under these Terms, no rights are granted to you. We may create and use de-identified and aggregated data derived from use of the Service (which does not identify you or any individual) for any lawful purpose, including improving the Service. If you give us feedback or suggestions, you grant us a perpetual, irrevocable, royalty-free license to use it without restriction or obligation to you.

6. Fees, billing, automatic renewal, and cancellation

Automatic renewal. Paid plans are sold as subscriptions billed in advance through our payment processor (Stripe) on a monthly or annual basis. YOUR SUBSCRIPTION AUTOMATICALLY RENEWS AT THE THEN-CURRENT RATE FOR SUCCESSIVE PERIODS OF THE SAME LENGTH UNTIL YOU CANCEL, AND YOUR PAYMENT METHOD WILL BE CHARGED AT THE START OF EACH PERIOD. You authorize us and Stripe to charge your payment method for all fees when due.

Cancellation. You may cancel at any time from your account or by contacting us; cancellation stops future renewals and takes effect at the end of the current billing period. To avoid the next charge, cancel before that period renews.

Trials, taxes, changes, and refunds. A free trial or free month, where offered, lets you view scans and reports; applying fixes requires an active paid subscription, and unless you cancel before the trial ends, the subscription will begin and your payment method will be charged. Fees are exclusive of taxes, which you are responsible for. We may change prices or plans prospectively on notice (for example, by posting updated pricing or emailing you); changes apply to the next renewal. Early-adopter (“grandfathered”) pricing, where offered, applies only while your subscription remains continuously active. If a charge fails, we may suspend the Service until payment is resolved. Except where required by law, all payments are non-refundable and there are no refunds or credits for partial periods.

7. Acceptable use

You agree not to: connect sites you are not authorized to manage; use the Service in violation of any law or third-party right; interfere with, disrupt, or attempt to gain unauthorized access to the Service or its systems or other customers’ data; reverse engineer or copy the Service except as permitted by law; resell or provide the Service to third parties without our authorization; or use the Service to transmit malware or unlawful content. We may investigate and take appropriate action, including suspension or termination, for suspected violations.

8. Third-party services

The Service relies on third parties including Squarespace, our payment processor (Stripe), a third-party AI provider (used to generate fix suggestions), and email and hosting providers. Your use of those services is subject to their own terms, and your relationship with Squarespace is between you and Squarespace. We are not responsible or liable for third-party services, their availability, or their acts or omissions.

9. Disclaimers

THE SERVICE IS PROVIDED “AS IS” AND “AS AVAILABLE,” WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS, IMPLIED, OR STATUTORY, INCLUDING ANY IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT. Without limiting the foregoing, WE DO NOT WARRANT THAT THE SERVICE WILL DETECT ALL ACCESSIBILITY ISSUES, THAT FIXES WILL BE COMPLETE OR ERROR-FREE, THAT YOUR SITE WILL CONFORM TO ANY STANDARD OR LAW, OR THAT THE SERVICE WILL BE UNINTERRUPTED, SECURE, OR ERROR-FREE. Some jurisdictions do not allow the exclusion of certain warranties, so some of the above may not apply to you.

10. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, KAT ADA AND ITS OWNERS, OFFICERS, EMPLOYEES, AND CONTRACTORS WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF PROFITS, REVENUE, DATA, GOODWILL, OR BUSINESS, OR FOR ANY AMOUNTS ARISING FROM ANY THIRD-PARTY ACCESSIBILITY CLAIM, DEMAND LETTER, OR LAWSUIT BROUGHT AGAINST YOU, WHETHER BASED ON CONTRACT, TORT, STRICT LIABILITY, OR ANY OTHER THEORY, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

OUR TOTAL CUMULATIVE LIABILITY FOR ALL CLAIMS RELATING TO THE SERVICE WILL NOT EXCEED THE GREATER OF (A) THE AMOUNTS YOU PAID US FOR THE SERVICE IN THE TWELVE (12) MONTHS BEFORE THE EVENT GIVING RISE TO THE CLAIM, OR (B) ONE HUNDRED U.S. DOLLARS ($100). Some jurisdictions do not allow certain limitations, so some of the above may not apply to you. These limitations are a fundamental basis of the bargain between us.

11. Indemnification

You agree to indemnify, defend, and hold harmless Kat ADA and its owners, officers, employees, and contractors from and against any and all claims, demands, damages, liabilities, losses, and expenses (including reasonable attorneys’ fees) arising out of or related to: your website and its content; your use of or reliance on the Service; any accessibility claim, demand letter, or lawsuit brought against you by a third party; your breach of these Terms; or your violation of any law or third-party right. Kat ADA is a tool and service to assist your own accessibility efforts; it does not assume responsibility for your legal compliance. We will give you reasonable notice of a claim subject to indemnification, and you will control the defense (provided that any settlement affecting us requires our prior written consent); we may participate with our own counsel at our expense.

12. Assumption of risk; release

You understand and agree that automated accessibility testing detects only a portion of possible issues, that no tool or service can guarantee compliance, and that responsibility for your website’s accessibility remains with you. To the fullest extent permitted by law, you release Kat ADA from any claims, known or unknown, arising from your reliance on the Service or from any accessibility-related claim brought against you by a third party.

You expressly waive California Civil Code section 1542 (and any similar law in any other jurisdiction), which states: “A general release does not extend to claims that the creditor or releasing party does not know or suspect to exist in his or her favor at the time of executing the release, and that, if known by him or her, would have materially affected his or her settlement with the debtor or released party.”

13. Dispute resolution; binding arbitration; class-action waiver

PLEASE READ THIS SECTION CAREFULLY. IT AFFECTS YOUR LEGAL RIGHTS, INCLUDING YOUR RIGHT TO SUE IN COURT AND TO HAVE A JURY TRIAL.

Informal resolution. Before starting an arbitration, you agree to first contact us at hi@katadaapp.com and try to resolve the dispute informally for at least 30 days.

Arbitration. Any dispute, claim, or controversy arising out of or relating to these Terms or the Service that is not resolved informally will be resolved exclusively by final and binding arbitration, rather than in court, administered by the American Arbitration Association (AAA) under its applicable Consumer or Commercial Arbitration Rules, before a single arbitrator, seated in Orange County, California. The Federal Arbitration Act governs the interpretation and enforcement of this section. The arbitrator has exclusive authority to resolve any dispute about the interpretation, applicability, enforceability, or formation of this arbitration agreement, including whether a claim is arbitrable. Either party may bring a qualifying claim in small-claims court, and either party may seek injunctive or equitable relief in court to protect intellectual property or confidential information.

Class-action waiver. You and Kat ADA 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 or join the claims of more than one person.

Costs and opt-out. Each party is responsible for its own attorneys’ fees except as the rules or applicable law provide. You may opt out of this arbitration agreement by emailing hi@katadaapp.com within 30 days of first accepting these Terms, stating your name and that you opt out of arbitration. If any portion of this section is found unenforceable, the remainder will continue to apply, except that if the class-action waiver is found unenforceable as to a particular claim, that claim (and only that claim) will proceed in court.

Time to file. To the extent permitted by law, any claim relating to the Service must be filed within one (1) year after it arose, or it is permanently barred.

14. Term; suspension; termination; survival

These Terms apply while you use the Service. You may stop using the Service and cancel at any time. We may suspend or terminate your access, with or without notice, if you violate these Terms, fail to pay, create risk or legal exposure for us, or to comply with law. On termination, your right to use the Service ends; provisions that by their nature should survive (including Sections 4–13 and 15–18) will survive.

15. Changes to these Terms

We may update these Terms. For material changes, we will post the updated Terms with a new “Last updated” date and, where appropriate, provide additional notice. Changes are effective when posted, and your continued use of the Service after that means you accept the updated Terms.

16. Governing law and venue

These Terms are governed by the laws of the State of California, without regard to conflict-of-laws rules. Subject to Section 13, the state and federal courts located in Orange County, California have exclusive jurisdiction over any dispute not subject to arbitration, and you consent to their personal jurisdiction and venue.

17. General

Force majeure: we are not liable for delays or failures caused by events beyond our reasonable control. Assignment: you may not assign these Terms without our consent; we may assign them in connection with a merger, acquisition, or sale of assets. Severability: if any provision is unenforceable, the rest remains in effect. Entire agreement: these Terms and the Privacy Policy are the entire agreement between us regarding the Service and supersede prior agreements. No waiver: our failure to enforce a provision is not a waiver. No third-party beneficiaries. Relationship: the parties are independent contractors. Notices and electronic communications: you consent to receive communications from us electronically (by email or by posting on the Service), and we may send notices to the email associated with your account; legal notices to us must be sent to the contact below.
