Terms

Prelaunch draft, requiring owner review. Operator name, business address, jurisdiction and consumer-law terms remain to be supplied. This draft is not a declaration accepted on the owner’s behalf.

The learning service

Yabai Sensei provides an independent N5 preparation curriculum. It does not promise complete JLPT N5 coverage, exam results, fluency or native-speaker-reviewed content. Level estimates and progress measures describe practice, not certification.

Your account

Sign-in is provided through Neon Auth. Keep your password and recovery email secure. You can export and delete your learning data in Settings. Humor is optional; turn it off in Settings or any lesson.

Free launch

All roadmap lessons, listening audio and reviews are currently free. No payment details or subscription are required. Sign-in is required to save progress and continue beyond the guest sample. Lesson prerequisites still apply.

Optional paid plans may be introduced later. Prices and access changes will be explained before they take effect. Using the free service does not authorize a charge; any future subscription requires an explicit purchase.

Acceptable use and content

Use the service for learning. Do not attack the service, access another learner’s records, upload content you do not have rights to use. Third-party components and audio retain their stated licenses. Original lessons and branding belong to their respective rights holders.

Availability and corrections

Lessons may be revised or withdrawn to correct errors. Earlier progress retains its content version. Report errors through Support. Offline answers need successful synchronization before they are safely stored in your account.

Before launch

The owner must review these terms, publish verified contact details and confirm applicable requirements for the free service. Payment account setup is deferred until a paid model is introduced.
