Privacy Policy

Quiz Harbor, the English edition of 診断つくーる!診断ランド, handles visitor information as described below.

Information we store

When a visitor creates a quiz, we store the submitted display name, title, description, questions, and results. Display names are optional, self-reported, and are not identity-verified. We also use local browser storage for device-level play counts. To reduce duplicate or abusive reports, we store report details and a non-reversible identifier generated from request information such as an IP address.

Advertising

We use Google AdSense. Google and other third-party vendors may use cookies, web beacons, IP addresses, and similar technologies to show and measure ads. Read how Google uses information from sites that use its services, or manage preferences in Google Ads Settings.

How information is used

  • To provide quiz creation, publishing, display, and sharing.
  • To prevent abuse and respond to policy violations.
  • To improve the service.
  • To display advertising and support site operation.

User submissions

Do not submit names, addresses, school names, contact details, or other information that identifies you or another person. Harassment, illegal material, explicit sexual content, threats, and other harmful submissions may be blocked or removed.
