These Terms and Conditions (the "Terms") are entered into between you and Junyun Limited ("we", "us" or "our") and govern your access to and use of the TranslateBuff browser extension, the TranslateBuff Windows desktop client, and the translatebuff.com website and its related services. Please read these Terms carefully before using the Service, in particular the clauses shown in bold, which exclude or limit our liability, and the clauses covering automatic subscription renewal, refunds and dispute resolution.

8. Subscription Plans, Billing and Automatic Renewal

8.1 Plans and prices. The Service offers a free plan and paid Subscription Plans. The entitlements, usage quota, billing cycle and price of each plan are as published on our pricing page.

8.2 Automatic renewal. Paid subscriptions renew automatically. Unless you cancel before the end of the current billing cycle, your subscription will renew automatically at the end of each billing cycle for a further cycle of the same length, and will be charged automatically to your selected payment method at the price published at the time of renewal.

8.3 Payment authorisation. By completing your first subscription purchase, you authorise us and our payment service providers to charge your selected payment method on each renewal date until you cancel or the authorisation is withdrawn.

8.4 Payment service providers. Subscription payments are processed through third-party payment channels we integrate with. When using such a channel you are also bound by that channel's own terms. We do not store your full card number or equivalent payment credentials.

8.5 Taxes. Whether published prices are inclusive of tax is as indicated on the pricing page. You are responsible for any taxes that applicable law in your location requires you to bear.

8.6 Failed renewal and grace period. If a renewal charge fails, the subscription enters a grace period. During the grace period you may continue to use the Service on your paid plan and we will prompt you to update your payment method. If the charge succeeds during the grace period, the subscription is extended by one billing cycle. If the charge has still not succeeded when the grace period ends, the subscription terminates and the account is downgraded to the free plan. The length of the grace period is as shown in your account centre.

8.7 Usage quota. Quota under a paid plan resets periodically in accordance with the published rules. Unused quota does not carry over to the next period and has no cash value.

8.8 Price changes. We may change subscription prices. A price change applies only to billing cycles beginning after it takes effect, and we will notify you before it takes effect in the manner set out in Clause 20. If you do not accept the new price, you may cancel before it takes effect.

9. Refunds

9.1 Monthly subscriptions. You may request a refund within 24 hours of your initial purchase.

9.2 Annual subscriptions. You may request a refund within 72 hours of your initial purchase.

9.3 To request a refund, contact us using the details in Clause 23 with your order information and the reason for your request.

9.4 Refunds are not available where: the request is made after the periods above; the charge is an automatic renewal rather than an initial purchase; you have made substantial use of the Service before requesting the refund; or your account has been suspended or terminated because of your breach of these Terms.

9.5 Approved refunds are returned to your original payment method. The time to receive funds depends on your payment channel.

9.6 Where mandatory consumer protection law in your jurisdiction grants you refund, withdrawal or cancellation rights more favourable than this Clause, those rights prevail, and nothing in this Clause limits or excludes them.

10. Cancellation, Reactivation and Downgrade

10.1 You may cancel at any time from your account centre, without giving a reason.

10.2 After cancellation your subscription remains active until the end of the current billing cycle, and you keep full access to your paid plan during that period. At the end of the cycle your account is downgraded to the free plan and no further charges are made. Cancellation alone does not entitle you to a pro-rata refund.

10.3 You may reactivate your subscription at any time before the end of the current billing cycle, after which automatic renewal resumes on the original cycle.

10.4 After downgrade to the free plan, your account and order history are retained, but features and quota exclusive to paid plans are no longer available.

11. User Content and Intellectual Property

11.1 The Service and all of its components (including software, algorithms, interfaces, design, text, graphics, marks and documentation) are owned by us or our licensors and are protected by copyright, trademark and other laws. These Terms transfer no ownership in the Service to you.

11.2 You retain all rights in your User Content. You grant us a limited, non-exclusive, royalty-free licence to process and transmit your User Content, including forwarding it to Third-Party Model Providers, solely for the purpose of providing the Service to you.

11.3 You must ensure that you hold the necessary rights in the User Content you submit and that processing it does not infringe the rights of any third party.

11.4 Output is generated automatically by third-party AI models. To the extent permitted by applicable law, we claim no rights in Output. Because of how such models work, Output may be identical or similar to results obtained by others; we do not warrant that it is unique or that it is capable of copyright protection. You are responsible for assessing whether Output is suitable and lawful for your intended use.

12. Data and Privacy

12.1 We collect, use and protect your personal information in accordance with the Privacy Policy. By using the Service you confirm that you have read and understood the Privacy Policy.

12.2 To perform translation, we forward the content you submit for translation to Third-Party Model Providers, which process that data on our instructions.

12.3 To keep the Service secure and to diagnose faults, we record operational logs (such as access time, IP address and events) and retain them for the periods described in the Privacy Policy.

12.4 Whether a Third-Party Model Provider uses the content you submit for model training is governed by that provider's own policy. We give preference to providers that state they do not use customer data for training, but we cannot guarantee this.

13. Third-Party Services

13.1 The Service may contain links to, or integrations with, third-party websites, products or services (such as browser extension stores and payment channels). Those third parties are governed by their own terms and policies, and we are not responsible for their content, conduct or availability.

13.2 Third-Party Model Providers are treated differently. They form part of how we deliver translation, and we remain responsible to you for the availability of the translation service. Our liability for loss caused by such a provider (for example, incorrect model output or a service outage) is subject to Clause 17.

14. Changes to and Interruption of the Service

14.1 We may temporarily interrupt or restrict all or part of the Service for upgrades, maintenance, fault repair or to comply with law. For planned maintenance we will make reasonable efforts to give advance notice.

14.2 We may discontinue the Service or any part of it. If doing so means we can no longer provide subscription entitlements you have already paid for, we will refund the fees corresponding to the unserved period on a pro-rata basis.

15. Term and Termination

15.1 These Terms take effect when you begin using the Service and continue until terminated in accordance with them.

15.2 You may terminate these Terms at any time by ceasing to use the Service and uninstalling the relevant software. Your paid subscription is then handled in accordance with Clause 10.

15.3 If you breach these Terms, we may suspend or terminate your account and these Terms.

15.4 On termination your right to use the Service ends immediately. Clause 11 (User Content and Intellectual Property), Clause 16 (Disclaimers), Clause 17 (Limitation of Liability), Clause 18 (Indemnity), Clause 22 (Governing Law and Dispute Resolution), and any other clause that by its nature should survive, continue in effect after termination.

16. Disclaimers

16.1 To the maximum extent permitted by applicable law, the Service is provided "as is" and "as available", without warranty of any kind, whether express or implied, including the implied warranties of merchantability, fitness for a particular purpose, non-infringement and uninterrupted use.

16.2 We do not warrant that the Service will be uninterrupted, error-free or completely secure, or that it will meet your particular requirements.

16.3 Translations are generated by third-party AI models. We make reasonable efforts to select reliable providers, but we give no warranty as to the accuracy, completeness or suitability of any translation. You should not rely on Output alone in contexts that demand high accuracy, such as medical, legal, financial or safety-critical use.

16.4 We are not liable for failure to perform these Terms caused by events beyond our reasonable control, including natural disasters, war, acts of government, cyber-attack, or failures of infrastructure or third-party services.

17. Limitation of Liability

17.1 To the maximum extent permitted by applicable law, we are not liable for any indirect, incidental, special, consequential or punitive damages, including loss of profit, loss of data, business interruption or loss of goodwill, whether or not we have been advised of the possibility of such damages.

17.2 To the maximum extent permitted by applicable law, our total aggregate liability to you under these Terms or in connection with the Service will not exceed the total amount you actually paid for the Service in the twelve (12) months preceding the event giving rise to the claim.

17.3 Some jurisdictions do not allow the exclusion or limitation of certain warranties or liabilities, so the above exclusions and limitations may not apply to you in full. In those cases our liability is limited to the minimum extent permitted by applicable law.

18. Indemnity

18.1 You will indemnify and hold us harmless against any claim, loss, liability or expense (including reasonable legal fees) we incur arising out of your breach of these Terms, your breach of applicable law, or your infringement of the rights of a third party.

19. Export Control and Sanctions

19.1 You represent and warrant that you are not located in, and are not a resident of, any country or region subject to applicable export control or economic sanctions restrictions, and that you are not on any applicable restricted-party list.

19.2 You must not export, re-export or otherwise make the Service available to any such country, region, entity or individual.

20. Changes to These Terms

20.1 We may revise these Terms from time to time. Revised Terms will be published on this page with an updated "last updated" date.

20.2 For material revisions we will give you at least thirty (30) days' notice before they take effect, by website notice, in-product notice, or email to the address associated with your account, as appropriate.

20.3 Continuing to use the Service after a revision takes effect means you accept the revised Terms. If you do not accept them, stop using the Service before they take effect; if you are a paying subscriber you may cancel under Clause 10.

21. Language

21.1 These Terms may be translated into other languages for your convenience.

21.2 In the event of any ambiguity or conflict between language versions, the English version prevails.

22. Governing Law and Dispute Resolution

22.2 You must also comply with the laws applicable to you in your own location when using the Service.

22.3 Informal resolution first. For any dispute arising out of these Terms or the Service, you agree to contact us first using the details in Clause 23, and both parties will attempt to resolve the matter in good faith.

22.6 Where mandatory law in your jurisdiction gives you the right to bring proceedings in your local courts, nothing in this Clause excludes that right.

23. General

23.1 Severability. If any provision of these Terms is held invalid or unenforceable, the remaining provisions remain in effect.

23.2 No waiver. Our failure or delay in exercising any right under these Terms is not a waiver of that right.

23.3 Assignment. You may not assign your rights or obligations under these Terms without our written consent. We may assign these Terms in connection with a merger, acquisition or transfer of assets.

23.4 Entire agreement. These Terms, together with the Privacy Policy, constitute the entire agreement between you and us regarding the Service and supersede all prior oral or written communications.

23.5 Headings. Headings are for convenience only and do not affect interpretation.
