Privacy Policy

Overview

Japan Tax Calculator (japantaxcalculator.com) is committed to protecting your privacy. This Privacy Policy explains what information we collect, how we use it, and your rights regarding your data when you use our tax calculator and educational articles.

1. Information We Collect

Calculator Data

When you use our tax calculator, all calculations are performed entirely in your browser. We do not collect, transmit, or store the income figures, deduction amounts, or any other financial data you enter into the calculator. Your tax data never leaves your device.

Automatically Collected Data

Like most websites, our servers may automatically collect certain technical information when you visit, including:

• IP address
• Browser type and version
• Operating system
• Referring URL
• Pages visited and time spent
• Date and time of access

This data is used in aggregate form to understand site usage, improve performance, and maintain security. It is not used to personally identify individual visitors.

2. Cookies & Tracking

We may use essential cookies required for the website to function properly. We may also use analytics tools (such as privacy-respecting analytics) to understand how visitors use our site. These tools collect anonymized usage data and do not track you across other websites.

We do not use advertising cookies or sell your data to third parties.

3. How We Use Your Information

Any information we collect is used solely to:

• Provide and maintain our website and calculator
• Analyze site usage to improve our content and tools
• Ensure the security and integrity of our services
• Comply with legal obligations

4. Data Sharing

We do not sell, rent, or share your personal information with third parties for marketing purposes. We may share anonymized, aggregated data with service providers who assist in operating our website (e.g., hosting providers), subject to appropriate data protection agreements.

5. Data Retention

Server logs containing automatically collected data are retained for a limited period necessary for security and operational purposes, after which they are deleted. Since the calculator operates entirely in your browser, no financial data is retained on our servers.

6. Your Rights

Depending on your jurisdiction, you may have rights regarding your personal data, including the right to access, correct, delete, or restrict processing of your data. If you are located in the European Economic Area (EEA), you have rights under the General Data Protection Regulation (GDPR). If you are located in Japan, the Act on the Protection of Personal Information (個人情報保護法) may apply.

To exercise any of these rights, please contact us through the information provided on our About page.

7. Third-Party Links

Our website contains links to external websites, including government resources like the National Tax Agency (国税庁). We are not responsible for the privacy practices of these external sites. We encourage you to review the privacy policies of any third-party sites you visit.

8. Children's Privacy

Our website is not directed at children under the age of 16. We do not knowingly collect personal information from children.

9. Changes to This Policy

We may update this Privacy Policy from time to time. Changes will be posted on this page with an updated revision date. Your continued use of the website after changes are posted constitutes acceptance of the revised policy.
