We respect your privacy and clearly explain how we handle submitted information.

Information We Collect

When you use contact forms, we may collect your name, email address, and message content.

How We Use It

  • To respond to your inquiries.
  • To improve the service and maintain the site.
  • To send optional updates you agree to receive.

Cookies

We use basic cookies to improve user experience and stability monitoring.

Third-party Services

We use services such as Vercel and Resend for hosting and email delivery.

Retention and Rights

You can request access, correction, or deletion of your data by sending an email request.

If you have questions, please contact us via the contact page.

Processing principles

We keep collected data as concise as possible. Contact forms are used for reply, project scoping, and improving service quality, and do not create user profiles for ad targeting.

  • Only minimum information needed for communication is used.
  • Processing is bounded by retention windows and user intent.
  • Logs are used for operational quality and security inspection only.

Cookies and third-party services

The site uses basic browser and delivery services for security and stability. By default these are configured for minimal function and do not include aggressive tracking. If you want to remove non-essential cookies, please check your browser setting.

Services used for delivery may include Vercel and Resend. We do not sell information to any ad exchange.

Retention timeline

Contact data is generally retained for up to 24 months for service and audit purposes, and can be removed earlier after verified request.

This page was updated on 2026-08-20 and will be revised when processing scopes or legal requirements change.

User choices

You may ask what data was submitted, request correction, request deletion, or limit future communication. To help us identify the record, use the same email address that was submitted through the contact form. We may ask for a short verification step before making changes.

Before sending sensitive business information, we recommend reading the contact page and sharing only the details required for an initial assessment. Strategy inquiries can usually begin with objective, timeline, and expected outcome rather than confidential files.
