Terms

Terms of Service

These terms describe Yujie's service scope, conditions of use, and responsibility boundaries in direct language.

Pro purchases and auto-renewal

Yujie Pro is available as an auto-renewing annual subscription or a one-time lifetime purchase. The annual plan renews and charges your Apple Account within 24 hours before the current period ends unless you cancel at least 24 hours beforehand in Apple Account subscription settings. Lifetime is a one-time purchase and does not renew. Both options unlock the same Pro features; the purchase screen shows the price in your local currency. Purchases can be restored with the same Apple Account. Apple handles refunds under its policies.

Service scope

Yujie is a badminton tracking and post-match review tool for Apple Watch and iPhone users. It is not a medical service, automatic officiating system, or professional tactical judging product.

Usage requirements

You are responsible for using Yujie on supported Apple platforms and for the safety of your own devices, account access, and exported data.

Feature boundaries

Yujie aims to provide stable tracking and review, but it does not guarantee zero error across every environment, device state, or network condition.

Updates and contact

If these terms change, the updated version will be published on the website or inside the product. Continued use after that generally means you accept the updated terms.
