Privacy · Public beta
The selector works without an account or form submission.
This site does not ask for a name, email address, payment information, or precise location. Selector answers remain in page memory and are not stored by Japan Decision Lab.
Aggregate measurement
Cloudflare Web Analytics measures page visits, paths, referrers, device categories, and page performance. Cloudflare describes this product as privacy-first and says it does not collect or use visitors' personal data. Its current documentation says query strings and custom events are not recorded.
Local decision events
The interface emits a non-identifying event structure inside the browser for quality testing. No first-party event endpoint receives selector answers, decision opens, or source-click events. Affiliate click and conversion events are not active.
Hosting and security
Cloudflare may process operational request data such as IP address, user agent, timestamps, and essential security information for service delivery under its own terms. This is separate from the Web Analytics product.
External links and changes
Official-source links lead to third-party sites with their own privacy practices. No affiliate redirect is active. This notice will be updated before email collection, persistent first-party tracking, or affiliate redirects are enabled, with consent controls where applicable.
