QuipJot Terms of Service

Your account

• You sign in with an email verification code; the iOS app also supports Sign in with Apple. One account shares your saved items and study progress across apps.
• Keep the inbox that receives your codes secure, and you are responsible for activity under your account. Contact us promptly if someone else is using it.
• You must be at least 13. If you are under 18, use the Service with a parent or guardian's consent.

Free features and subscriptions

• Study features — saving and syncing, word books, list and card review, and study stats — are free.
• AI features such as translation, word explanations and speaking practice require an active QuipJot subscription and are subject to monthly usage limits. A subscription belongs to your account and works in every app.
• We may change free features and subscription contents; changes that reduce an active subscription apply only after the current billing period ends.

Purchases, renewal and refunds

• Plans are sold on quipjot.com and in the QuipJot Mac app, not inside the iOS app. Prices, allowances and billing periods are those shown at checkout when you buy. Payments are processed by Alipay in Chinese yuan, or by Stripe for card payments in US dollars where offered.
• Alipay purchases are one-time payments for one month, one year or the 7-day trial. They do not renew automatically; buy again when your period ends. The trial is limited to one per account and per email address, including after the account is deleted and registered again, and does not turn into a paid plan.
• Stripe card subscriptions renew automatically at the end of each billing period until you cancel. You can cancel future renewals at any time in the app's subscription management; you keep access until the paid period ends.
• Your plan starts as soon as payment is confirmed. Because it is a digital service delivered immediately, payments are not refundable once the plan is active, including for partly used periods, unused allowance and the trial, except as set out below.
• We will refund duplicate or mistaken charges, and the unused part of a paid period if a fault on our side stops you from using your plan's core features and we cannot fix it within a reasonable time. Rights you have under mandatory consumer law, such as withdrawal rights in the EU or UK, are not affected. Any other refund is at our discretion.
• To request a refund or ask about a charge, email info@luchenyuan.com with your account email and the time of the order. Approved refunds go back to the original payment method, and the plan paid for by a refunded or disputed payment ends when the refund or dispute is processed.

Your content

The text, notes and study records you save are yours. You allow us to store, process and sync them across your devices to provide the Service, including sending text you submit for translation to our translation providers. Make sure you have the right to submit that content, and do not submit confidential or highly sensitive text you would not want processed by an AI service.

AI output and word books

• Translations, definitions and some example sentences are generated by AI. They may be inaccurate or incomplete and are for study reference only, not a substitute for professional translation or an authoritative dictionary.
• Word book definitions are based on ECDICT (MIT License); example sentences in the graduate-exam word books come from past exam texts. Rights remain with their respective owners.

Acceptable use

When using the Service, you must not:

• break the law, or use the Service for unlawful or infringing content;
• call, scrape or resell the Service in bulk by automated means, or get around usage limits;
• crack, reverse engineer or interfere with the Service or its security;
• impersonate others, or share an account to avoid paying for a subscription;
• create multiple accounts to claim the trial repeatedly.

We may restrict or close accounts that break these rules.

Deleting your account and termination

You can stop using the Service at any time. In the iOS app, Me → Account → Delete account, or in the macOS app, the account menu → Delete account, permanently removes your account with all saved items and study progress; it takes effect immediately and cannot be undone. Unused paid time is forfeited without a refund. Cancel any Stripe auto-renewal before deleting. As described in the Privacy Policy, we keep a minimal record of a deleted account, including its hashed email address and purchase history. If we discontinue the Service, we will announce it on the website in advance and give you time to export your data.

Disclaimers and limitation of liability

The Service is provided "as is". We work to keep it reliable but do not promise it will be uninterrupted or error-free, or that it will produce particular learning results. To the extent permitted by law, we are not liable for indirect losses, and our total liability to you is limited to the amount you paid for the Service in the 12 months before the event. Liability that cannot be excluded by law is not affected.

Governing law and changes

These terms are governed by the laws of the People's Republic of China. Both sides will first try to resolve any dispute through discussion; failing that, it will go to a competent people's court where we are located. We may update these terms; material changes will be posted on this page with a new date, and continuing to use the Service means you accept the updated terms.
