By using a Lock&Learn app you agree to these terms. They cover the whole family: trivia, Chinese, and Japanese.
Lock&Learn shows curated trivia questions and facts on your widgets and inside the app. Lock&Learn Chinese and Lock&Learn Japanese show vocabulary that follows the official HSK and JLPT syllabi. All of it is offered for general interest and learning, not as professional advice.
Lock&Learn+ unlocks every topic or level in the app where you buy it; each app has its own purchase. It is offered as a yearly subscription that starts with a free trial, or as a one-time lifetime unlock, both processed by Apple through your App Store account. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period, and can be managed or cancelled at any time in your App Store account settings. The free trial converts to a paid subscription unless cancelled before the trial ends.
All content is provided as-is. Facts are checked against reliable sources before they ship, vocabulary is drawn from established dictionaries, and new content lands monthly. We correct mistakes when we find them or when you point them out.
You may not copy, resell, or redistribute the apps’ content or attempt to interfere with the apps’ operation.
These terms may be updated as the apps evolve. The current version always lives at this address, with the date at the top.
