Privacy Policy

Key Line Osaka (“we”, “us”) operates the adult piano studio at 1-8-15 Shinsaibashi, Chuo-ku, Osaka 542-0085, Japan, and the website unbenstras.top. This Privacy Policy explains how we handle personal information in accordance with Japan’s Act on the Protection of Personal Information (APPI) and guidance from the Personal Information Protection Commission (PPC).

We collect information you provide when you enquire about lessons, book sessions, or communicate with us by phone or email. Typical data includes your name, email address, telephone number, preferred schedule, and brief notes about your musical background that help us place you with a teacher. Payment records for lessons may include invoice details required for accounting under Japanese law.

We use personal information to respond to enquiries, schedule and deliver lessons, manage studio operations, send service-related notices (such as schedule changes), and improve our website experience. We do not sell personal information. Where we rely on optional analytics cookies, we do so only after you Accept or enable analytics in Settings; Declining keeps necessary cookies only.

Legal basis and purpose limitation

Under the APPI, we acquire personal information through lawful and fair means and use it within the purposes notified in this policy or otherwise clearly indicated at the time of collection. If we need to use information for a new purpose beyond what a data subject would reasonably expect, we will obtain consent where required or take other measures prescribed by the APPI.

Sharing and entrustment

We may entrust processing to service providers who support email hosting, scheduling tools, or payment processing. When we do so, we supervise those providers appropriately under the APPI. We may disclose information when required by Japanese law, court order, or requests from competent authorities, including cooperation with the PPC when applicable.

Security and retention

We take organisational and technical security measures appropriate to the size of our studio to prevent leakage, loss, or damage of personal data. We retain enquiry and student records only as long as needed for the original purposes, accounting duties, or dispute resolution, then delete or anonymise them in a secure manner.

Your rights

Subject to the APPI, you may request notification of purpose of use, disclosure, correction, addition, deletion, suspension of use, or suspension of third-party provision regarding your retained personal data. To exercise these rights, contact us at [email protected] or +81 6 6251 3384, or write to the studio address above. We may need to verify your identity before responding. You may also contact the Personal Information Protection Commission of Japan for guidance on APPI matters.

International transfers

Our primary operations and data storage are in Japan. If any tool involves transfer outside Japan, we will take measures required by the APPI, such as confirming an adequate level of protection or obtaining consent where necessary.

Updates

We may update this policy to reflect legal or operational changes. The revised version will be posted on this page with an updated effective note. Continued use of our services after posting constitutes awareness of the updated terms where permitted by law.
