Terms of Use

What we offer

Musclecn (website musclecn.com, iOS app “明刚笔记”) offers training programs, an exercise library, a training log, learning articles and film features; the website also has comments, Old Friends club posts and topic polls. The website and the app share one account and your training records stay in sync.

Content is written by editors and checked by reviewers before publishing; it is not medical or individual training advice. Stop if you feel unwell. Content marked "dev test data" only validates the system and is not training guidance.

Accounts

Sign-in is by SMS code (email code as fallback); the first sign-in creates an account with a display name taken from the email prefix (editable).

Signing in requires declaring you are 18 or older and accepting these terms; the server records the version and time.

One phone number or one email maps to one account; they are not merged automatically.

Your content

Training logs, training notes and personal plans are private by default; only you can see them.

Program questions become public only if editors feature them, and never show who asked.

Comments and Old Friends posts become public after review and show your display name; you can withdraw or delete your own content. Do not post other people's private information, infringing or unlawful content; we remove such content or restrict posting.

Updates and contact

When these terms change, the version changes and you will be asked to confirm at your next sign-in.
