Service Content\n\n### 2.1 Scope of Service\n\nThe Service provides Personal Users with storage, synchronization and management functions for notes and related materials. Specific features are subject to what is actually delivered by the product, and we reserve the right to adjust, improve, suspend or discontinue certain features.\n\n### 2.2 Service Availability\n\n- The Service is provided on an \"as-is\" and \"as-available\" basis. **We do not warrant** that the Service will be continuously available, uninterrupted or error-free.\n- We may suspend part or all of the Service within a reasonable period for maintenance, upgrades, failures or other reasons, and will endeavour to give advance notice.\n\n### 2.3 Geographic Availability\n\nDue to legal and regulatory requirements, compliance obligations or business decisions, we may **restrict or completely stop** the availability of the Service in specific regions.

Eligibility and Accounts\n\n### 3.1 Eligibility\n\n- You shall be a natural person with **full civil capacity** or a duly established and existing legal entity.\n- **Use by minors** is described in Section 11 of the *MiYu Note Privacy Policy*; this Agreement and the Privacy Policy are consistent with respect to age requirements.\n- You are not a person with whom we are prohibited from doing business (including, without limitation, users who are subjects of sanctions).\n\n### 3.2 Account Registration and Use\n\n- You must provide a true and accurate email address or Mainland China mobile phone number for registration.\n- You shall properly safeguard your login credentials (email\u002Fphone number, verification codes, login password, Space Key password and Space Key) and shall be responsible for all operations performed through your account.\n- In principle, a single natural person may hold only **one (1)** account; multiple-account behaviour may be deemed abuse and may trigger account restrictions.\n\n### 3.3 Account Security\n\n- If you discover any unauthorized use, leakage or loss, please notify us **immediately** through the in-app feedback channel or our **security mailbox (security@miyunote.cn)**. We will assist in taking necessary measures within a reasonable time, but **we are not liable for losses caused by your failure to notify us in time**.\n- Where we reasonably suspect that account security is threatened, we may **proactively** take measures such as temporary freezing or mandatory secondary verification.\n\n---\n\n## 4. Data Security and End-to-End Encryption (Core Terms)\n\n### 4.1 Encryption Mechanism\n\nThe Service uses End-to-End Encryption (E2EE) to process user data. Your note bodies and attachments are encrypted on your local device before being uploaded to the server.\n\n### 4.2 Zero-Knowledge Architecture\n\nThe server does not retain any of your plaintext data. To support essential interactions and basic retrieval, the following information is stored or processed **without end-to-end encryption**: Space name, Space background image, note title, note icon, note cover image, user nickname, and registered email\u002Fphone number. Apart from these, the bodies of your notes and attachments cannot be read by the server in any technical way.\n\n### 4.3 Space Key and User Responsibility\n\n- You expressly acknowledge and agree that **the Space Key is the sole credential for decrypting your data**.\n- Due to the zero-knowledge architecture, we **neither hold nor are able to obtain** your Space Key, and **we cannot recover it for you**.\n- **If you lose your Space Key or Space Key password without having made a local backup, we cannot recover your data or reset your access by any technical means.** Any permanent data loss and related damage arising therefrom shall be borne by you alone.\n- For the specific mechanism of the Space Key, see Section 3 of the *MiYu Note Privacy Policy*.\n\n### 4.4 Backup Recommendation\n\nThe Service should not be the **sole** storage destination for your core assets. You should perform regular independent backups of your critical data.\n\n---\n\n## 5. User Conduct Rules\n\n### 5.1 Basic Obligations\n\nYou undertake to comply with the laws and regulations of the People's Republic of China (including the *Cybersecurity Law*, *Data Security Law*, *Personal Information Protection Law*, *Consumer Rights Protection Law*, *Criminal Law*, *Public Security Administration Punishments Law*, *Provisions on the Governance of the Online Information Content Ecology*, etc.) and the applicable laws of your jurisdiction.\n\n### 5.2 Prohibited Conduct\n\nYou **must not** use the Service to engage in any of the following:\n\n1. Creating, reproducing or disseminating content that violates national laws and regulations (including, without limitation, content endangering national security, advocating terrorism or extremism, inciting subversion of state power or secession, pornography, false information, or disturbing social order);\n2.

Violating export-control or sanctions regulations of your jurisdiction or the People's Republic of China;\n8. Any other conduct in violation of Internet content-governance regulations such as the *Provisions on the Administration of Internet User Public Account Information Services* or the *Provisions on the Governance of Cyberbullying Information*.\n\n### 5.3 Allocation of Responsibility for E2EE Content\n\n- Given that end-to-end encryption makes it **technically impossible** for us to review the specific content you store, you bear **full compliance and legality responsibility** for any information stored or transmitted through the Service.\n- Upon receiving a **lawful, valid and legally binding** notice or request from a judicial authority, government body or rights holder, we will cooperate in taking necessary measures (including, without limitation, suspending or terminating your account).\n\n### 5.4 Abuse of Refund Rights\n\n- You understand and agree that using the Service's refund policy in a \"subscribe – refund – resubscribe\" loop with the intent to **avoid payment over the long term** constitutes a breach of this Agreement.\n- We **do not impose system-level limits on the number of refunds**, but **we reserve the right to conduct risk-control reviews and take operational measures**, including without limitation: requiring additional verification, delaying the refund, **refusing to offer you further subscriptions** after your current subscription period ends, or restricting or permanently banning your account. For specific review objects, criteria and appeal procedures, see Section 3.6 of the *MiYu Note Refund Policy*.\n- **Commitment to normal Users**: We will only take the above measures when we have reasonable evidence that abuse has occurred; the refund rights of normal Users will not be affected.\n\n---\n\n## 6.

Invoice details are set out on the checkout page.\n- Exchange rates for cross-border payments are subject to the rate at the time of payment processing.\n\n### 6.4 Right of Withdrawal and Cooling-off Period (Reference)\n\n- The laws of Mainland China **currently do not provide a unified statutory cooling-off period** for online digital subscription services.\n- We **additionally** provide all Users with a **thirty (30) calendar day** no-reason full refund right (see Section 3 of the *MiYu Note Refund Policy*). After the 30-day no-reason refund period expires, you may still apply for a **pro-rata** refund under Section 3 of the *MiYu Note Refund Policy*.\n- **The above entitlements do not affect** any statutory rights you enjoy under the *Consumer Rights Protection Law of the People's Republic of China*, the *Product Quality Law of the People's Republic of China*, the *Civil Code of the People's Republic of China* and other laws (including remedies where the Service is defective or does not conform to the agreement).\n\n### 6.5 Transaction Confirmation\n\nUpon successful subscription, we will send a transaction-confirmation email to the email address you have provided **within twenty-four (24) hours**, including the order number, amount, currency, renewal date, cancellation method and refund method.\n\n---\n\n## 7. Suspension, Restriction and Termination\n\n### 7.1 Measures We May Take\n\nWhere any of the following circumstances occurs, we may, **after reasonable judgement**, take the following measures:\n\n- **Temporary restriction**: suspending certain or all functions;\n- **Account ban**: permanently or temporarily terminating your account;\n- **Data handling**: deleting offending content or banning the account as appropriate.\n\nTriggering circumstances include:\n\n1.

Since we currently do not provide automatic renewal, you only need to refrain from renewing after your current Subscription Period ends.\n- For the **specific procedure** for closing your account, see Section 8 of the *MiYu Note Refund Policy*; for rules on **data retention and destruction** after closure, see Section 7 of the *MiYu Note Privacy Policy*.\n\n---\n\n## 8.
