Terms of Service

1. Acceptance

LingoHey ("we") provides a browser extension and the website https://lingohey.com/ (together, the "Service"). By using the Service you agree to these terms and our Privacy Policy. If you do not agree, please do not use the Service.

2. Early-bird period

• The Service is in its early-bird period. All prices of paid plans are early-bird prices.
• During this period, features, plan allowances and other values may change. We will notify you at least 7 days before any change (in the product or by email).
• How price changes and allowance reductions affect periods you have already paid for: see sections 5 and 6.

3. Accounts

Some features require signing in. Keep your account secure and do not share it; you are responsible for activity under your account. Each person should use only one account for the free allowance.

4. Free plan, paid plans and fair use

• The free plan includes a limited allowance for AI features (such as weekly AI usage and a number of video summaries and refined subtitles), reset every Monday 00:00 (UTC+8).
• Paid plans include a multiple of the free allowance, as described on the purchase page.
• Fair use: allowances exist to keep the Service available to everyone and to prevent abuse. We also apply reasonable-use limits (for example, the total length of videos processed per week and AI usage per day) that normal personal learning does not reach. If you reach one, we will tell you why and when it resets; it then resets automatically.
• Do not share or resell your account, call the Service in bulk with scripts or automation, forge requests or otherwise work around limits. If you do, we may restrict the affected features and, in serious cases, terminate the account (payments are handled under section 7).

5. Price changes

• Price increases: periods you have already paid for are not affected. The new price applies from your next period, and we will notify you at least 7 days in advance.
• Price drop compensation: if we lower the price of the plan you bought, by default we extend your plan for the remaining paid period by the difference (extra days = remaining days × (old price − new price) ÷ new price). You may instead request a pro-rata refund of the difference (refund = (old price − new price) × remaining days ÷ days in the period).

6. Allowance reductions

If, during your paid period, any allowance of the plan you bought is reduced by more than 20%, you may request a refund pro-rated by the remaining time (refund = amount paid × remaining days ÷ days in the period), or keep using the plan.

7. Refunds

• Annual plans: full refund, no questions asked, within 14 days of purchase.
• Quarterly and monthly plans: full refund, no questions asked, within 7 days of purchase.
• The no-questions-asked refund is limited to once per account. Refunds under sections 5 and 6 are not subject to this limit.
• Refunds go back to the original payment method; fees charged by the payment provider follow its rules.

8. Renewal and cancellation

Purchases through Alipay, WeChat Pay and similar methods are prepaid and do not renew automatically. Subscriptions paid by card renew automatically; you can cancel at any time and keep access until the end of the paid period.

9. AI-generated content

Explanations, translations, notes, video summaries, refined subtitles and similar results are generated by AI, may contain mistakes and are for learning reference only. Some results are cached and shared between users (see the Privacy Policy). Use "Report a problem" if you find an issue.

10. Disclaimer and limitation of liability

The Service is provided "as is". To the extent permitted by law, we are not liable for indirect damages, and our total liability to you will not exceed the amount you paid for the Service in the previous 12 months.

11. Termination

You can stop using the Service at any time and delete your account on the My data page. If we discontinue the Service, we will notify you in advance and refund paid fees pro-rated by the remaining time.

12. Changes to these terms

We may update these terms. We will give at least 7 days' notice of material changes (in the product or by email); continuing to use the Service after a change takes effect means you accept it.
