Terms of Service

Terms for using Lang Study's learning tools

2026/06/28

Product-use boundary

The terms keep the real product shape visible: Lang Study supports practice, print, review, and handoff workflows, but those outputs are practical aids rather than official records.

Allowed learning use

Worksheets, assignment notes, paper-review links, copied handoffs, and study plans can be shared for personal, family, tutoring, or classroom practice.

Progress limits

Local HSK1 progress, returned-paper marks, copied notes, and saved settings are not guaranteed school records or cross-device backups.

Payment boundary

Checkout, subscriptions, refunds, lifetime access, and billing recovery follow the shown plan terms and payment-provider flow when paid features are enabled.

Use the product terms

Make worksheet

Create a same-set printable worksheet for personal, tutoring, family, or classroom practice.

Classroom inquiry

Ask about classroom use before sharing student names, notes, or repeated assignment workflows.

Review pricing

Compare free practice, Pro, lifetime, and classroom fit before checkout.

Same-set continuation paths

Each link preserves the starter HSK1 set so the legal boundary can return to practice or account follow-up without losing scope.

Page: Product-use boundary
Starter set: 人 口 日 月 山 水
Boundary: browser-local progress, returned-paper marks, copied handoffs, account files, and provider-processed services are separate unless a feature explicitly imports or syncs them.
Use: copy this for a learner, parent, teacher, or support helper who needs to continue practice without treating legal pages as progress sync or official school records.
