Terms of Service

Last updated: April 2026

Agreement

By using Kontab (kontab.co), you agree to these terms. If you do not agree, do not use the service. Kontab is operated by KZO Lab LLC.

What Kontab is

Kontab is an EA exam readiness tool. It helps tax professionals assess their preparedness for the IRS Enrolled Agent exam using AI-generated questions and a confidence-aware scoring system.

Kontab is not an accredited educational institution. It does not guarantee exam passage. All questions are AI-generated and grounded in IRS publications and the Internal Revenue Code — they are not licensed from Prometric, Gleim, Becker, Wiley, or any other commercial exam prep provider.

Use of the service

You may use Kontab for personal EA exam preparation. You may not:

AI-generated content

Questions and coaching responses are generated by the Anthropic Claude API. While we design questions to be grounded in IRS publications and the IRC, AI-generated content may contain errors. Always verify tax law through authoritative IRS sources before acting on any information in Kontab.

Kontab is a study readiness tool — it is not legal or tax advice.

No warranty

Kontab is provided "as is" without warranty of any kind. We do not warrant that the service will be error-free, uninterrupted, or that any particular readiness score predicts exam passage. Use at your own discretion.

Limitation of liability

To the maximum extent permitted by law, KZO Lab LLC shall not be liable for any indirect, incidental, special, or consequential damages arising from your use of Kontab, including but not limited to exam failure, loss of data, or reliance on AI-generated content.

Intellectual property

The Kontab name, logo, scoring system, and interface are the property of KZO Lab LLC. AI-generated question content is based on publicly available government sources (IRS publications, Revenue Rulings, IRC) and is not proprietary to third-party exam prep providers.

Changes to these terms

We may update these terms as the product evolves. Continued use of Kontab after changes constitutes acceptance of the revised terms.

Governing law

These terms are governed by the laws of the State of Florida, without regard to conflict of law provisions.
