Contact us

結 -MUSUBI- (“we”) handles personal information in accordance with the following policy.

1. Information We Collect
Through our contact forms (project inquiries, and feedback or app ideas), email or phone, we may receive your name, company or business name, email address, phone number and the details of your inquiry. When you submit a form, the service that receives it may record the sending device’s IP address and browser type to filter out spam.

2. Purpose of Use
We use this information only to respond to inquiries, to propose and provide services, and to handle contracts. App ideas you send help us decide which apps to build (if we build an app based on an idea, no payment is made to the person who sent it).

3. Third-Party Disclosure
Except where required by law, we do not disclose personal information to third parties without consent.

4. Service Providers (Including Providers Outside Japan)
Form submissions are received and stored by Netlify, Inc. (United States), and inquiry emails are received and sent through Google LLC (Gmail, United States). Netlify may use Automattic Inc. (Akismet, United States) to filter out spam. We use AI (Claude, by Anthropic, PBC, United States) to organise inquiries and draft replies; replies are sent by our staff. This site also uses Google Fonts (Google LLC) to display text, so opening a page sends your device’s IP address and similar data to Google. Information on the personal information protection system of the United States is available from Japan’s Personal Information Protection Commission (“Foreign systems: United States”, in Japanese).

5. Retention
Form submissions and their notification emails are deleted one year after we receive them. Records related to contracts are kept for the period required by law.

6. Requests About Your Information
To ask us to disclose, correct, delete or stop using your information, please contact us below. We will confirm your identity before responding.

7. Contact
For questions about this policy, please contact us at: 結 -MUSUBI- (Masaki Kushida) / musubi.bss@gmail.com
