MiYu Note User Service Agreement (Last updated: May 26, 2026)
Welcome to MiYu Note (hereinafter the “Service”). Before using the Service, please read this Agreement carefully. By clicking agree or by actually using the Service, you are deemed to have read and agreed to be bound by this Agreement.
I. Scope of Services
The Service provides users with functions such as storage, synchronization, and management of notes and related materials. Specific features are subject to what the product actually provides.
II. Data Security and End-to-End Encryption
1. Encryption mechanism
The Service processes user data using end-to-end encryption (End-to-End Encryption, E2EE). Your note content and attachments are encrypted on your local device before being uploaded to the server.
2. Zero-Knowledge statement
The server does not retain any of your plaintext data. However, to maintain core service interactions and basic search capabilities, the following information will be stored or processed in a non-end-to-end-encrypted manner: space name, space background image, note title, note icon, note header image, user nickname, and email account. For all other note body text and resource files, the server cannot technically read their contents.
3. User assumption of risk
You expressly acknowledge and agree that the space key is the sole credential to decrypt your data. Because of the zero-knowledge architecture, the service provider does not hold and cannot obtain your keys. If you lose your space key, the service provider cannot by any technical means recover your data or reset access permissions for you. Permanent data loss and related damages arising therefrom shall be borne by you alone.
III. Account and Security
You shall properly safeguard login credentials (including but not limited to email verification codes, login passwords, space keys, etc.) and be responsible for all actions taken through your account. If you discover unauthorized use, please notify us immediately.
IV. User Conduct
You undertake to comply with applicable laws and regulations. Because end-to-end encryption makes it technically impossible for the service provider to review the specific content you store, you bear absolute responsibility for the compliance and legality of any information you store or transmit using the Service. You must not use the Service to create, reproduce, or disseminate illegal or infringing content, or to interfere with the normal operation of the Service. Any legal disputes or government penalties arising from user conduct shall be borne by the user.
V. Intellectual Property
- The intellectual property rights in the software, interface design, and related documentation included in the Service belong to the operator or its licensors.
- Content stored by users in the Service remains copyrighted by the user or the original rights holder.
VI. Disclaimer and Limitation of Liability (Key Terms)
1. Provided “as is”
The Service and cloud storage are provided on an “AS IS” and “AS AVAILABLE” basis. The service provider does not guarantee that the Service will never be interrupted, that packets will never be lost, or that cloud data will never be corrupted. The Service should not be your sole storage destination for core assets; you should routinely back up your core data independently.
2. Encryption-specific disclaimer
Given the nature of end-to-end encryption, if data leakage, lockout, or loss results from client device failure, system crash, accidental deletion, improper safeguarding of keys/passwords, or attacks targeting your personal devices, the service provider shall not assume any liability for compensation.
3. Damages and force majeure
To the maximum extent permitted by law, for service interruptions, synchronization delays, or data loss caused by force majeure, network failures, third-party infrastructure or cloud provider outages, distributed network attacks, or similar reasons, the service provider shall not be liable for consequential or incidental damages.
4. Cap on total liability
Regardless of the form of litigation or claim (contract, tort, negligence, or otherwise), the aggregate maximum total liability of the service provider to users arising from the Service shall in no event exceed:
- Subscription or storage fees actually paid by the user to the service provider for using the Service in the twelve (12) months before the claim event; or
- Zero (0) if the user uses the free version or free storage quota.
VII. Changes to the Agreement
We may revise this Agreement from time to time and will notify you by reasonable means after revision. Your continued use of the Service constitutes acceptance of the revised Agreement.
