Privacy Policy

D&S, Inc. ("D&S", "we", "us") respects your privacy. This policy explains what personal data this website collects, why we collect it, how we handle it, and the choices you have. It covers this website only.

1. Who we are

D&S, Inc. is a software and digital engineering company headquartered in Tokyo, Japan. We are the party responsible for the personal data described in this policy.

2. Information we collect

• Analytics data. Standard technical information such as IP address, browser type, device, approximate location, referral source, and pages viewed, collected automatically through analytics and cookies when you visit the site.
• Contact form. If you use our contact form, the details you submit, your name, email address, company (optional), and message, so we can read and respond to your inquiry.

3. How we use it

We use this data only to:

• respond to inquiries you send through the contact form; and
• understand how the site is used, and operate, secure, and improve it.

We do not use this data for anything else, and we do not sell your personal data.

4. How we share it

We do not sell or rent personal data.

To run this site we entrust data to service providers that process it on our behalf, under our supervision and their own terms:

• Cloudflare, Inc. — website hosting, and Turnstile bot and spam verification on the contact form (which processes your IP address and basic browser signals when you submit the form);
• Google LLC — analytics (Google Tag Manager and Analytics);
• Slack (Salesforce, Inc.) — delivery of contact-form submissions to us.

These providers act as processors handling data on our behalf, not as independent recipients. When your browser loads this site, it also retrieves web fonts and interface icons from third-party content delivery networks (Google Fonts and unpkg), which receive your IP address in order to deliver those files. Separately, we may disclose personal data where required by law.

5. International handling

We are based in Japan. To run this site, personal data may be handled by third-party providers located outside Japan, including Google LLC (United States), Cloudflare, Inc. (United States), and Slack (Salesforce, Inc., United States). This means your information may be transferred to and stored in the United States. You can obtain information about the countries involved and how your data is handled by contacting us using the details below.

6. Storage and security

We store personal data on access-controlled systems and apply reasonable technical and organizational measures to protect it against loss, misuse, and unauthorized access. Where we store or process personal data on cloud services located outside Japan (primarily in the United States), we assess the data-protection framework of that country and apply the measures necessary to keep the data secure.

7. Retention

We keep personal data only for as long as needed for the purposes described above, or as required by law, and then delete or anonymize it.

8. Your rights

You may request access to, correction of, or deletion of your personal data, and you may ask us to stop using it. To make a request, contact us using the details below. We may ask you to verify your identity before we act on a request, and we will respond within a reasonable time in accordance with applicable law.

9. Cookies and analytics

This site uses cookies and analytics (including Google Tag Manager) to understand how the site is used and to improve it. You can control or block cookies through your browser settings; some features may not work as intended if you do.

10. Changes to this policy

We may update this policy from time to time. The "last updated" date above reflects the most recent version.

11. Contact

For any question or request about this policy or your personal data, contact us at [email protected].
