Shiosai Audit House, 835 E 6th Street, 湖新井町, 北海道, Japan, is the controller for personal data collected through this website. Contact: hello@datavizlab.digital, +81-2-977-5559.

Data we collect

When you submit an inquiry or newsletter form we collect your name, email address, message content, and optional fields such as preferred call date, fiscal year-end, and engagement of interest. Server logs may record IP address, browser type, and pages visited.

Purposes

We use this data to respond to engagement inquiries, schedule scoping calls, send closing notes if you subscribe, and maintain the security of the site. We do not sell personal data.

Legal bases

Processing is based on steps prior to entering a contract (responding to your request), our legitimate interest in operating a professional practice website, and consent where you opt into optional analytics cookies or newsletter messages.

Retention

Inquiry records are kept for up to 24 months unless an engagement is formed, in which case retention follows the engagement letter and Japanese professional record-keeping requirements for audit files. Newsletter subscriptions remain until you unsubscribe. Server logs are typically rotated within 90 days.

Your rights

Subject to applicable Japanese law, you may request access, correction, deletion, or restriction of personal data we hold about you, and you may withdraw consent for optional processing. Contact us at the email above. You may also lodge a complaint with the Personal Information Protection Commission of Japan.

International transfers

Our primary operations and records for this practice are in Japan. If a hosting or email provider processes data outside Japan, we take steps consistent with the Act on the Protection of Personal Information, including contractual safeguards where required.
