SmartPropFact Terms of Service
This English text is a courtesy translation provided for convenience. The official text of these Terms is the Japanese version; if there is any inconsistency between the two, the Japanese version prevails.
These Terms of Service (these "Terms") set out the conditions for using "SmartPropFact" (the "Service") provided by Chomchana Trevai (sole proprietor), trade name SmartPropFact ("we," "us," or the "Operator"). By registering for and using the Service, you agree to these Terms.
Article 1 (Application)
- These Terms govern the relationship between you and the Operator with respect to your use of the Service.
- Guidelines and notices we publish within the Service from time to time ("Supplementary Rules") form part of these Terms. If a Supplementary Rule conflicts with these Terms, the Supplementary Rule prevails.
Article 2 (Definitions)
- "User" means an individual who has agreed to these Terms and completed registration for the Service.
- "User Content" means the document images, files, and other information a User uploads to or enters into the Service.
- "Extracted Data" means data that the Service reads, classifies, and structures from User Content.
- "Paid Plans" means the Standard and Premium plans described in Article 6.
- "Output Documents" means the documents and data the Service produces from a User's records, including the 青色申告決算書 (blue-return financial statements for real-estate income), the 収支内訳書 (income and expenditure statement), and CSV exports.
Article 3 (Nature of the Service — Self-Preparation Software)
- The Service is self-preparation software: a tool with which individuals who own rental property organize their own records, compute their real-estate income, and prepare year-end documents for their own Japanese income-tax filing (確定申告).
- The Operator is not a licensed tax accountant (税理士) or tax accountant corporation. Neither the Operator nor the Service performs tax agency services, tax-document preparation on another person's behalf, or tax consultation as defined in Article 2 of the Certified Tax Accountant Act (税理士法).
- Output Documents are materials for the User's own review and correction, based on the User's records. You are responsible for reviewing their content and for using them in a filing that you make yourself. The Operator never signs a return, never submits a return on your behalf, and never represents you before any tax authority.
- The Service's Q&A feature is limited to information about your own recorded data and general information about publicly available tax rules. It does not provide individualized tax advice (税務相談). If you need professional judgment for your specific situation, consult a licensed tax accountant.
- Refund and tax projections shown by the Service are estimates expressed as ranges and do not guarantee any filing outcome (see Article 9).
Article 4 (Registration)
- A person who wishes to use the Service shall apply for registration by the method we specify, after agreeing to these Terms.
- The Service is available only to individuals aged 18 or over.
- Users shall keep their registered information accurate and up to date.
- We may decline or revoke registration if the applicant (i) provided false, erroneous, or incomplete information; (ii) previously violated these Terms; (iii) is, or is involved with, anti-social forces (organized crime groups and similar); or (iv) is otherwise judged by us to be unsuitable for registration.
Article 5 (Account Management)
