Terms of Service

What the service is

Submission Chain is an educational reference and personal training journal for Brazilian Jiu-Jitsu. It is informational only and is not a substitute for a qualified instructor.

BJJ carries a real risk of injury. Train under proper supervision, warm up, and go at a safe pace. You are responsible for your own safety and for how you use anything you learn here.

Your account and content

You are responsible for the activity under your account and for keeping access to your email secure, since sign-in uses email magic links.

The content you create (sessions, flows, profile) stays yours. You grant us only the permission needed to store it and show it back to you as part of running the service.

Acceptable use

Don't misuse the service: no unlawful use, no attempts to break, overload, or gain unauthorised access to it, and no automated scraping or bulk copying of the technique data.

Availability and warranty

The service is provided “as is”, without warranties of any kind. We may change, suspend, or discontinue features, and we don't guarantee it will always be available or error-free.

To the extent permitted by law, we are not liable for injuries, losses, or damages arising from your use of the service or reliance on its content.

Governing law

These terms are governed by the laws of the Republic of China (Taiwan), and any dispute is subject to the jurisdiction of the courts of Taiwan.
