Terms of Service

The service

Itsumade ("the service") is a WaniKani completion forecasting and study management tool. It runs Monte Carlo simulations based on study parameters to estimate when you might complete the WaniKani course. It also provides a pacing dashboard, weekly planner, and workload tracking for Pro users.

Forecasts are estimates, not guarantees. Actual completion time depends on factors the simulation cannot predict.

Accounts

You may use the simulator without an account. Creating an account gives you access to the WaniKani integration and pacing dashboard. You are responsible for keeping your login credentials secure.

Free and Pro tiers

The forecast simulator is free and always will be. Pro features (dashboard, planner, behavior analysis) require a paid subscription. Pricing is listed on the pricing page.

Payments are processed by Gumroad. All purchases are subject to Gumroad's terms of sale. Itsumade does not handle payment card data directly.

If the service shuts down, Pro features will remain available for as long as the servers are running. No refunds are offered for time-based plans that have already started, but you can cancel at any time to prevent future charges.

WaniKani integration

Itsumade is not affiliated with Tofugu LLC or WaniKani. We access WaniKani data through their public API v2 using your personal API key, which you provide voluntarily.

Acceptable use

Do not abuse the service by sending automated bulk requests, attempting to access other users' data, or interfering with service operation. We reserve the right to suspend accounts that violate these terms.

Limitation of liability

The service is provided "as is" without warranty of any kind. We are not liable for any damages arising from your use of the service, including but not limited to inaccurate forecasts or service downtime.

Changes

We may update these terms from time to time. Continued use of the service after changes constitutes acceptance of the updated terms.
