Terms of Service

Effective 13 November 2026

These terms set out your rights and ours when you use Muxun. By installing or using Muxun, you agree to them.

They cover Muxun on the Chrome Web Store, on Microsoft Edge Add-ons and on its website, muxun.app. This service is operated by TINGJI (听记), based in New Zealand ("we").

What Muxun does

• Muxun recognises the video you are watching on a web page, finds a matching subtitle from third-party subtitle libraries, shows it on the video and syncs it to the dialogue on your computer.
• Muxun does not provide videos and cannot download them.
• Subtitles come from third-party libraries, uploaded by their users. We do not own them, and we cannot promise that every film has one or that every subtitle and its timing are accurate.

How you may use it

• Muxun is for your personal viewing.
• Do not use Muxun to infringe anyone's copyright, to watch unauthorised copies of videos, or for anything unlawful.
• Do not bulk-download subtitles, scrape subtitle libraries or get around their limits.
• Keep your email account safe: anyone who gets a sign-in code from your inbox can sign in to your Muxun account.
• Do not crack, modify or interfere with Muxun, or get around the limits of membership or of the subtitle allowance.

Rights in subtitles and in Muxun

• Subtitles belong to their authors or rights holders. Subtitles you import or export are for your own use; do not redistribute or sell them.
• Muxun's software, name and logo belong to us. These terms let you use Muxun; they do not transfer those rights to you.

Free and membership

• Account: finding subtitles needs a Muxun account. Enter your email and the code we send you, with no password; your first sign-in creates the account. Importing your own subtitles, automatic sync and fine-tuning work without an account.
• An episode: finding and using a subtitle for one episode or one film counts as one episode. Switching to another subtitle for the same episode, searching again, or moving on automatically when the dialogue doesn't match does not count again.
• Free: subtitles for one episode every 3 days: once you have found one, the next one is available 3 days later. Importing your own subtitles, automatic sync and fine-tuning have no limits. The look is Cinema.
• Trial: a new account gets a 3-day trial from its first sign-in, with subtitles for one episode a day and all four looks. Each email address gets only one trial. When it ends, you go back to the free version.
• Muxun membership: opened with a Muxun account (you sign in with your email and a code, no password), monthly or yearly. Subtitles for up to 30 episodes a day and 300 episodes every 30 days, and all four looks.
• When the allowance resets: a member's daily allowance resets at midnight Beijing time (UTC+8); the 30-day allowance resets every 30 days from the day you join. Once it runs out, you can't find subtitles for a new episode, but importing your own subtitles still works.
• Signing in on several browsers: an account can be signed in on up to 2 browsers at once. When you sign in on a third, the one used least recently is signed out.
• Price: a monthly plan is CN¥9.90, NZ$9.90, US$9.90, A$9.90, €9.90 or £9.90 for 30 days; a yearly plan is 99 in the same currency (for example US$99) for a year. The currency depends on where you are; the price and taxes shown at checkout apply.
• 20% off the first month: if you have never paid before, your first monthly plan is 20% off, including 30 days bought with Alipay. A monthly plan that renews automatically is full price from the second month.
• Payment: depending on the country you pay from, handled by Paddle in the EU and the UK and by Stripe elsewhere; the ways you can pay are shown on the payment page. We never see your full card number. Cards from the EU and the UK must go through Paddle; if one is used through Stripe (for example over a VPN), we refund the payment in full, stop the subscription, take back that membership time and email you.
• Automatic renewal: monthly and yearly plans paid by card, Apple Pay or Google Pay renew automatically; the first and later prices are shown before you pay. We email you 7 days before a yearly plan renews. You can cancel any time under "Manage subscription"; you will not be charged again, and your membership stays on until the end of the period you paid for. Uninstalling Muxun does not cancel a renewal.
• Alipay: payments are in Chinese yuan only and can't renew automatically. With Alipay, a monthly plan is a one-off 30 days and a yearly plan a one-off 365 days; we email you 3 days before it ends so you can renew yourself. Alipay isn't available in the EU or the UK.
• Receipts: for each new or renewed membership, Muxun emails a receipt to your sign-in address; Stripe or Paddle also sends its own receipt.
• Switching from monthly to yearly: this can't be done directly under "Manage subscription". Cancel the monthly plan there, then buy a yearly plan in Muxun; the yearly plan is first charged when the current monthly period ends.
• If the renewal price changes, we tell you at least 30 days ahead. A period you have already paid for is not affected.
• Membership is for your personal use. Do not transfer or resell it.
• For refunds, see the Refund Policy.

Payments for Muxun go to the Stripe and Paddle accounts of TINGJI (听记). Orders paid through Paddle are processed by our online reseller Paddle.com. Paddle.com is the Merchant of Record for those orders and provides all customer service inquiries and handles returns for them. For orders paid through Stripe, the seller is TINGJI (听记), and your bank statement shows TINGJI* MUXUN.

Third-party services

• Third-party subtitle libraries, the title database, Stripe and Paddle are independent services with their own terms and privacy policies.
• They may change their limits or terms, or shut down. If a library stops working, or its terms no longer allow us to use it, we may remove it.

Privacy

How we handle data is set out in the Privacy Policy.

Updates and changes

• Muxun updates itself through your browser's extension store. Features may be added, changed or removed.
• If we make an important change to these terms, we will tell you in Muxun or on our website before it takes effect. Using Muxun after that means you accept the new terms.
• If a change clearly reduces what membership includes, contact us and we will treat it as a problem on our side under the Refund Policy.

Service and liability

• Muxun is provided as it is. We work hard on it, but we do not promise it will always be available or free of errors.
• To the extent the law allows, we are not liable for indirect losses, and our total liability to you is limited to what you paid for Muxun in the past 12 months.
• Nothing here limits rights you have under consumer law where you live that cannot be excluded.

Stopping

• You can uninstall Muxun at any time. If you are a member, cancel the renewal separately under "Manage subscription".
• You can delete your account in Muxun, confirming with one more emailed code. If your membership renews automatically, cancel it first under "Manage subscription". What happens to the records on the server is set out in the Privacy Policy.
• If someone breaks these terms, for example by reselling an account, finding subtitles in bulk with scripts, cracking Muxun, or through fraud or a security risk, we may switch off their membership.

Governing law

These terms are governed by the laws of New Zealand. This does not affect your rights under consumer law where you live.
