These Terms of Service ("Terms") govern your access to and use of Taxation.ai (the "Platform"), an AI-powered tax preparation service operated by Vaionex Corporation ("Company," "we," "our," or "us"), a company incorporated in the State of Delaware, United States.

By creating an account or using the Platform, you agree to be bound by these Terms. If you do not agree, you must not use the Platform.

2. Service Description

Taxation.ai provides AI-assisted tax preparation tools that help users organize financial information, identify potential deductions, and prepare tax returns. The Platform serves users in the United States, European Union, United Kingdom, and 20+ additional countries.

The AI-generated content, suggestions, and outputs provided by Taxation.ai are for informational purposes only and do not constitute professional tax advice, legal advice, or financial advice. You should always consult with a qualified tax professional, accountant, or financial advisor before making decisions based on information provided by the Platform. Vaionex Corporation is not a licensed tax preparation firm, accounting firm, or law firm. We do not guarantee the accuracy, completeness, or applicability of any AI-generated output to your specific tax situation.

You retain ownership of the data you submit to the Platform. By using the Platform, you grant us a limited, non-exclusive license to process your data solely for the purpose of providing the service.

AI-generated outputs (such as tax suggestions) are provided as part of the service. You may use these outputs for your personal tax preparation purposes. These outputs are generated algorithmically and are not guaranteed to be unique or proprietary.

11. Governing Law

These Terms shall be governed by and construed in accordance with the laws of the State of Delaware, United States, without regard to its conflict of law provisions.

Notwithstanding the foregoing, if you are a consumer resident in the EU, you retain the right to bring proceedings before the courts of your country of habitual residence, and you may also use the European Commission's Online Dispute Resolution platform at https://ec.europa.eu/consumers/odr.
