1. Acceptance
By downloading, installing, accessing, or using the App, you confirm that you have read, understood, and agree to be bound by this User Agreement. If you do not agree, do not use the App.
Where the App is obtained through Apple’s App Store, your use is also subject to Apple’s applicable store terms. As between you and us, we (not Apple) are responsible for the App and its content, subject to this Agreement and applicable law.
2. Eligibility
You must be able to form a legally binding contract in your jurisdiction to accept this Agreement. If you are under the age of majority where you live, you may use the App only with the consent and supervision of a parent or legal guardian.
For users in the United States, the App is not directed to children under 13, and we do not knowingly collect personal information from children under 13 through the App in a manner that would trigger obligations under the U.S. Children’s Online Privacy Protection Act (“COPPA”). See our Privacy Policy for details.
3. License to use the App
Subject to this Agreement and your compliance with it, we grant you a personal, limited, non-exclusive, non-transferable, revocable license to install and use the object code of the App on devices that you own or control, solely for your private, non-commercial entertainment.
You may not: (a) copy, modify, or create derivative works of the App except as allowed by applicable law; (b) reverse engineer, decompile, or disassemble the App except to the extent mandatory local law permits; (c) rent, lease, lend, sell, redistribute, or sublicense the App; (d) remove or alter proprietary notices; (e) use the App to build a competing product or service; or (f) use the App in violation of law or third-party rights.
4. Description of the experience
The App offers a portrait-oriented rhythm-action experience in which timing-based input (for example, tapping) affects bridge placement, scoring, combo progression, and related feedback. Available features may include different play modes (such as level-based, endless, or challenge-style rules), music packs or tracks, cosmetic or presentation options, local statistics, and optional virtual currency or items obtained through gameplay or in-app purchase.
We may update, balance, add, or remove features to improve the App, comply with law, or address technical or security needs. We do not guarantee uninterrupted or error-free operation.
5. Virtual items and in-app purchases
Optional in-app purchases (for example, virtual “gold” or similar currency) may be available. Purchases are processed by the platform provider (for example, Apple). Prices, billing, and refund rules are governed by that provider’s terms and policies.
Virtual items have no real-world monetary value, are non-redeemable for cash, and constitute a limited, revocable license to use them within the App. You do not acquire ownership of virtual items. We may adjust virtual economy balance where reasonably necessary for fairness or sustainability.
6. Acceptable use and fair play
You agree not to cheat, exploit, or harm the experience of others. Without limitation, you must not: use unauthorized automation, scripts, or bots; manipulate device time, input, or memory in a way intended to falsify scores or unlock content; interfere with the App’s normal operation or security; or attempt to gain unauthorized access to systems or data.
We may suspend or terminate access, reset local progress where technically appropriate, or restrict features if we reasonably believe you have violated this Section.
7. User content and conduct
If the App allows you to submit or display content (such as usernames or future social features), you represent that you have the rights to do so and that your content does not violate law or third-party rights. You grant us a non-exclusive, worldwide, royalty-free license to host, store, reproduce, and display such content solely as needed to operate and improve the App, unless a narrower scope is required by law.
8. Intellectual property
The App, including its name, branding, graphics, audio, text, software, and related materials, is owned by us or our licensors and is protected by intellectual property laws. The license in Section 3 does not transfer any ownership rights. Music packs and similar content are licensed for in-App use only unless we expressly state otherwise.
9. Third-party services
The App may rely on or link to third-party services (including the platform store, payment processing, analytics if enabled, and device features). Those services have their own terms and privacy practices. We are not responsible for third-party services except as required by applicable law.
10. Disclaimers
To the maximum extent permitted by applicable law, the App is provided “as is” and “as available,” without warranties of any kind, whether express, implied, or statutory, including implied warranties of merchantability, fitness for a particular purpose, title, and non-infringement.
Australia: Our goods and services come with guarantees that cannot be excluded under the Australian Consumer Law. You may be entitled to a replacement or refund for a major failure and compensation for any other reasonably foreseeable loss or damage. Nothing in this Agreement is intended to exclude, restrict, or modify those rights.
California (USA) and other U.S. states: Some states do not allow certain warranty exclusions; in those states, our warranties are limited to the extent permitted by law.
11. Limitation of liability
To the maximum extent permitted by applicable law, in no event will the Operator, its affiliates, or their respective directors, employees, or licensors be liable for any indirect, incidental, special, consequential, or punitive damages, or for loss of profits, data, or goodwill, arising from or related to your use of the App.
To the maximum extent permitted by applicable law, our aggregate liability for any claim arising out of or related to the App or this Agreement will not exceed the greater of (a) the amount you paid us for the App or in-app purchases in the twelve (12) months before the claim, or (b) fifty U.S. dollars (USD $50), except that this cap does not apply where prohibited (for example, where non-waivable consumer rights apply).
12. Indemnity
To the extent permitted by law, you agree to indemnify and hold harmless the Operator and its affiliates from claims, damages, losses, and expenses (including reasonable legal fees) arising from your misuse of the App, your violation of this Agreement, or your violation of third-party rights.
13. Term and termination
This Agreement begins when you first use the App and continues until terminated. You may stop using the App at any time. We may suspend or terminate your license if you materially breach this Agreement or if we discontinue the App where permitted by law.
Sections that by their nature should survive (including intellectual property, disclaimers, limitation of liability, indemnity, and governing law) will survive termination.
14. Changes to this Agreement
We may update this User Agreement from time to time. We will post the revised version with a new effective date. If changes are material, we will provide notice in a reasonable manner where practicable (for example, in-App notice or email if we have your address). Your continued use after the effective date of changes constitutes acceptance unless applicable law requires a different process.
15. Governing law and disputes
Except where mandatory local law provides otherwise (including non-waivable consumer protection rules), this Agreement is governed by the laws of the State of California, United States, excluding its conflict-of-law principles, and the federal laws of the United States applicable therein.
Informal resolution. Before filing a claim, you agree to contact us at meile-yb@163.com to try to resolve the dispute informally.
Class action waiver (where enforceable). To the extent permitted by applicable law, disputes will be brought only in an individual capacity, not as a plaintiff or class member in any class or representative proceeding. If a court holds this waiver unenforceable with respect to a particular claim, that claim may proceed in court; the remainder stays in effect.
Canada, Singapore, Australia, and other regions: Nothing in this Section limits your right to bring a complaint before a competent consumer protection agency or to pursue remedies that cannot be waived under the laws of your province, territory, or country.
16. Export and sanctions
You may not use or export the App except as authorized by law, including applicable export control and sanctions regulations.
17. Miscellaneous
If any provision is held invalid or unenforceable, the remaining provisions remain in effect. Failure to enforce a provision is not a waiver. You may not assign this Agreement without our consent; we may assign it in connection with a merger, acquisition, or sale of assets.
This Agreement, together with our Privacy Policy, is the entire agreement between you and us regarding the App and supersedes prior understandings on the same subject.
