Terms of Service

These terms are the agreement between you and DongYouGuan. By using our extension or this website, you agree to them. Operator: Allen Fong (individual developer; FANG AILUN is the same person, legal name as on passport), who receives Stripe payments personally. The merchant name on your card, Alipay or WeChat Pay statement may be FANG AILUN or the statement descriptor we set in Stripe; for card payments made through Paddle, the statement shows PADDLE.NET*. Contact email: support@dongyouguan.com.

1. What we provide

DongYouGuan is a Chrome extension (Chrome Web Store name: 懂油管 - 中文字幕翻译 for YouTube™) that translates the subtitles of YouTube videos into Chinese. It also offers supporting tools: comment and title translation, Chinese search, a full transcript, video highlights, investment risk hints, region translate (translating the text inside an area you select on the video picture) and playback speed control.

Translations, highlights and risk hints are generated by AI and can be wrong. Be especially careful with names, numbers and technical terms. We do not guarantee that translations are accurate or complete. Please check anything important yourself. Investment risk hints are for reference only, are not investment advice, and are not a judgement about the video creator.

DongYouGuan is intended for users who can already watch YouTube normally. A video must have subtitles to be translated.

2. Our relationship with YouTube and Google

DongYouGuan is an independent extension. It is not an official YouTube or Google product and is not affiliated with either.

The copyright in videos and subtitles belongs to their original authors. We only show translations on your own browser page. You are responsible for following YouTube's terms of service and the laws where you live.

3. Accounts

• The translation service we host requires you to sign in, with an email code or a Google account.
• One account can be used on any number of devices, signed in at the same time. Quota is counted per account. A sign-in stays active on a device for 90 days.
• An account is for you only. You may not resell it, rent it out, or share it with others for profit.
• Keep your email and sign-in safe. We treat use under your account as your own use.

4. Your own API key (advanced use)

Advanced users can switch to their own API key in Settings. This mode costs nothing from us (your API provider bills you for API usage) and needs no sign-in. Subtitle data goes straight from your browser to the provider you choose and does not pass through our servers. In this mode, the small image area you select with "region translate" is also sent by your browser straight to the address you entered, not through us. Any charges and terms between you and that provider are your agreement with them. We take no part in it and are not responsible for it.

5. Quota

• Quota is measured in tokens. Subtitle translation, comment and title translation, Chinese search, video highlights, risk deep analysis and other hosted features draw from the same quota (for risk deep analysis, free accounts get 5 runs a month and members use quota). Region translate draws from the same quota too.
• In the interface we mainly show it as "about X hours of video", with the token count in a smaller place. The conversion uses a measured average of about 170,000 tokens per hour of video. It is an estimate and varies with the video.
• Free plan: 300,000 tokens per month, about 1.75 hours of video, reset on the 1st of each month (Beijing time). Eligible new accounts get 200,000 extra tokens in the month they sign up, about 3 hours in total for that month. To be eligible, the email address must not be a disposable one, and on any one device only the first 2 new accounts in a month get the bonus.
• Paid plan: 6,000,000 tokens per month, about 30 hours of video. A period is 30 days counted from the day you start.
• Quota you do not use in one period does not carry over to the next.
• When quota runs out: On the free plan, you can finish the video you are watching (up to about 30 more minutes of video, subtitles only; region translate asks you to upgrade straight away), and from the next video you will be asked to upgrade; your quota comes back on the 1st of next month. On the paid plan, the service pauses until the next period and the interface shows the date it resumes. We do not sell top-up packs at the moment.
• Rewatching a video you have already watched on the same computer uses the cache on that computer and does not use quota. If you switch computers, clear your browser data, or the cache has been cleared, watching it again uses quota again. Speed control and subtitle size adjustments do not use quota.

6. Pricing and payment

All prices are in Chinese yuan (CNY). Who the seller is depends on the payment channel: when you pay through Stripe, the seller is the extension's operator personally (payee: FANG AILUN) and Stripe is only the payment processor; when payment is switched to Paddle, Paddle acts as the Merchant of Record and is the legal seller of that transaction (see below). Either way, it has nothing to do with Google or YouTube.

• Monthly: launch price CNY 19.9 / month, about 30 hours of video per month; list price CNY 29.9 / month. The launch period is the first 3 months starting from the day DongYouGuan is publicly listed on the Chrome Web Store, or until 500 paying users have taken the launch price, whichever comes first (the exact dates will be stated here on the listing day). The price switches on the day the launch period ends; it is not extended or reopened, and new subscriptions after that are CNY 29.9 / month. If you start during the launch period and your membership does not lapse, you keep paying CNY 19.9. "Does not lapse" means the subscription has not ended; if you cancel and then resume before it ends, that still counts. If you start again after it has ended, the price at that time applies. Whether you get the launch price depends on when you open the payment page; places are counted in the order payments complete, so when the limit is close, several people paying at the same time may all get the launch price.
• Yearly: launch price CNY 168 / year, list price CNY 198 / year, with the same quota as monthly, released month by month. The opening date will be announced separately; it cannot be bought before it opens.
• Monthly is by bank card only: paid through Stripe (only the payment processor; the seller is the operator personally) and renewed automatically every month. Each period is charged automatically when it ends, until you cancel. You can cancel at any time under "Manage subscription" in the extension. If Stripe is unavailable we may take payment through Paddle instead, and the payment page will say so. If you pay through Paddle, Paddle acts as the Merchant of Record and is the legal seller of that transaction (you buy from Paddle): it charges you and issues the receipt, and refunds are processed through Paddle too.
• 30-day one-time pass: you can pay by bank card, Alipay or WeChat Pay, at the same price as monthly for the period you buy in: CNY 19.9 during the launch period and CNY 29.9 after it. Each purchase is charged at the price on the day you buy; prices are not locked. One purchase gives you 30 days; it does not renew automatically. If you buy early, the extra days are added after your current end date. The 365-day pass opens together with the yearly plan, with the date announced separately.
• Starting monthly while you still have membership days (when you subscribe through Stripe): the first charge is postponed to the day your current days run out, so your membership does not lapse. Each account can postpone only once; if you have already postponed once, you have to wait until your current days run out before starting monthly; if you cancelled during the postponement, you can resume it under "Manage subscription" in the extension instead of starting again. If fewer than 48 hours are left, you are charged right away. While payment is switched to Paddle, the first charge is not postponed.
• Referral discount stays at CNY 10: the first charge is CNY 9.9 during the launch period and CNY 19.9 after it.
• If your card issuer charges cross-border or currency conversion fees, those are set by the bank and are not part of our listed price.

7. Cancelling a subscription

For a monthly subscription, cancel automatic renewal on the customer self-service page (Stripe's page, or Paddle's if the backup provider took the payment). The extension popup and the account section of Settings both have a "Manage subscription" entry. After you cancel, the next period is not charged and your membership lasts until the end of the current period. A 30-day one-time pass never renews, so there is nothing to cancel.

8. Refunds

You can get a full refund if you ask within 7 days of your first payment and your usage is no more than about 340,000 tokens (about 2 hours of video). "First payment" counts once per membership type: the first purchase of a 30-day pass and the first actual charge of a monthly subscription (and, once they open, of a yearly plan or 365-day pass) each qualify, and each account can get one refund per membership type; if your first monthly charge was postponed, the 7 days and the usage both count from the day of the actual first charge. In every other case, including renewal charges and repeat payments for the same membership type, payments are not refunded. Deleting your account is not itself a refund; apply first if you want one. How to apply and how the money comes back are in the Refund Policy.

Read the full Refund Policy

9. Invoices

Payments by bank card, Alipay or WeChat Pay through Stripe come with a Stripe electronic receipt; payments through Paddle come with a receipt issued by Paddle. We do not issue Chinese VAT invoices (fapiao).

10. Chargebacks and abuse

• If something is wrong with a charge, please email us first and we will deal with it. An account that files a chargeback with its bank will be suspended.
• Accounts that farm the free quota, register in bulk, resell accounts, or crack or bypass quota limits will be banned.
• We ban accounts, not IP addresses. After an account is suspended, the extension shows "Account suspended. Contact support if you have questions."

11. Availability

We do not promise the service runs 24 hours a day without interruption. A YouTube page redesign, a failure at a third-party model provider or an unstable network can make features temporarily unavailable.

Batches that fail (cannot reach the service, service error, or a section that did not get translated) are not charged against your quota. A video without subtitles cannot be translated yet and does not use quota either.

12. Changes to prices and features

We may change prices, quota and features. We will tell you ahead of time through the website, the extension or email. A price increase does not apply to a period you have already paid for. Monthly members who started during the launch period keep the launch price as long as their membership does not lapse.

13. Termination and account deletion

• You can stop using the service at any time. To delete your account, use the one-click option in the account section of Settings, or email us; we complete email requests within 15 business days.
• Deletion takes effect as soon as you confirm: you are signed out on all devices, the account is deactivated, and automatic renewal is cancelled on the spot. Remaining membership days and invite days are forfeited. Deleting the account is not itself a refund; apply under the Refund Policy first if you want one.
• Within 30 days, we delete your account and usage records. Payment records are kept for 7 years under Hong Kong's Inland Revenue Ordinance, for tax reconciliation, refunds and chargebacks: the records no longer hold your email, but they keep the payment provider's order IDs and similar IDs, which the payment provider can trace back to the payer. Your invite code and the invite in which you were the invitee are deleted; your reward-day ledger, the invites you made and your membership records are moved to a placeholder ID that holds no email, without affecting days the other person already received. If you sign up again with the same email within one year, you get a brand-new empty account but no new-user bonus. The device ID we use against abuse is kept for about 12 months. Deletion cannot be undone. See the Privacy Policy for exactly what is kept.
• If you break these terms, we may suspend or terminate your account.

14. Limitation of liability, governing law and disputes

Limitation of liability. To the fullest extent permitted by law: DongYouGuan is provided as is, and we do not guarantee that translations are accurate or complete or fit for your particular purpose; we are not liable for any indirect, incidental, special or consequential loss (including loss of profit, data or goodwill) arising from your use of, or inability to use, the service; and our total liability to you in connection with the service is limited to the fees you actually paid us in the 12 months before the event giving rise to the claim, or RMB 100 if you have not paid anything. This section does not exclude or limit any liability that cannot be excluded or limited by law, including loss caused by our wilful misconduct or gross negligence, and does not affect your statutory rights as a consumer.

Governing law and disputes. These terms are governed by and construed under the laws of the Hong Kong Special Administrative Region of the People's Republic of China. Any dispute arising from these terms or the service will first be negotiated in good faith; if that fails, it will be submitted to the courts of the Hong Kong Special Administrative Region. This does not affect any consumer protection given to you by the law where you live that cannot be excluded by agreement.
