Honest status.

Product state: This is an early language-game prototype. Signal Shift is playable now. Learner accounts, saved cross-device progress, adaptation services, entitlements, checkout, billing, and paid access are planned but not yet live.

Language scope: Korean is the first target language, with separate English-guided and Japanese-guided website experiences. Additional target and guidance languages may follow. Foundation, Functional, Nuance, and Advanced are internal practice bands only, not TOPIK, JLPT, CEFR, school-grade, fluency, or validated proficiency levels.

Claims: Prototype task measures describe performance inside the task: first-attempt accuracy, first-response latency, assistance, direction, context/register performance, and recognition versus production. Nakimaru Labs does not currently claim measured language-learning gains, fluency, proficiency, or clinical benefit.

First-party measurement: After a visitor chooses “Allow measurement,” Nakimaru Labs records page views and a small event set: drill start, drill completion, language switching, and contact-email clicks. A completion event may include first-try score, assistance count, and median response time. Individual answer choices are not transmitted.

Data collected: Measurement records include time, page, referrer, network address, approximate location, browser/device information, interface language, and the bounded event fields described above. We do not run advertising trackers, session replay, browser-fingerprinting scripts, or cross-brand identity profiles. The choice is stored in local browser storage and can be changed below. Do Not Track and Global Privacy Control signals disable collection.

Early access: The early-access form stores the submitted email address, consent, source, time, network address, approximate location, browser/device information, and referrer in a Nakimaru-specific list. It does not start an account, subscription, checkout, or payment.

Planned access: The target model is one Nakimaru Labs membership at USD $8.99/month, covering language-game lanes as they become available. This target is not live; accounts, checkout, billing, and paid access will require a later launch.
