Legal basis and retention
We process inquiry and newsletter data based on your request to contact us or receive communications, and our legitimate interest in operating the business. We retain contact and engagement-related correspondence for as long as needed to respond, maintain business records, and meet legal requirements, then delete or anonymize it when no longer necessary.
Cookies
We use one functional cookie, mbky_locale, to remember your selected language. It is not used for advertising or cross-site tracking. You can remove cookies through your browser settings; if removed, the site may default to your browser language or English on your next visit.
Service providers
We use trusted service providers to operate the site, including Resend (email delivery for contact form messages) and Vercel (website hosting). These providers process data on our behalf only as needed to provide their services. Some providers may process data outside Japan.
Sharing and sale of data
We do not sell your personal information. We share information only with service providers supporting site operation, when required by law, or when necessary to protect rights, safety, and security.
Your rights and choices
You may request access to, correction of, or deletion of your personal information, or withdraw consent for newsletter communications, by contacting us at support@mbky.co. We will respond within a reasonable period. You can unsubscribe from the newsletter at any time using the method provided in each message.
Security
We take reasonable measures to protect personal information, but no method of transmission or storage is completely secure.
Children
Our services and website are directed at adults in professional contexts. We do not knowingly collect personal information from children.
Changes and contact
We may update this policy from time to time by posting a revised version on this page with an updated date. Questions about privacy can be sent to support@mbky.co. Use of the website is also governed by our Terms of Service.
