Privacy Policy

Effective: August 11, 2026 · Last updated: August 11, 2026

Pillow Moon (the “we” or the “App”) takes your personal information and privacy very seriously. Sleep and emotion records are highly private information. We follow the principle of “minimum necessity,” collecting only what is required to provide the features. Please read this policy carefully before using the App. By using the App, you understand and agree to all the contents of this policy.

1. Information We Collect

1.1 Information You Provide

• Account information: When you choose to register and sign in, we collect your phone number (to verify your identity) and the nickname you set.
• User content: The goodnight postcards you write, bedtime reflection journal entries, mood/emotion tags, and sleep-companion records.
• Subscription information: Your membership status and subscription records (to verify your purchases and provide membership benefits).

1.2 Information We Collect Automatically

• Device information: Device model, operating system version, language, time zone, and anonymized device identifiers (for feature adaptation and analytics).
• Usage data: The features you use, the audio you play, and the ritual steps you complete, used to improve the product.
• Logs and crash information: App crash logs and exception stacks, used to diagnose and fix issues.

1.3 Information Collected by Third-Party Services

To provide push notifications, analytics, and other services, we may integrate third-party SDKs. Their collection and processing rules are governed by their respective privacy policies. We evaluate their compliance before integration and anonymize data whenever possible.

2. How We Use Your Information

• Provide, maintain, improve, and refine the App's features and services;
• Generate your personal sleep and emotion trend records for your own reference;
• Review and display the goodnight postcards you choose to make public (shown anonymously by default, not linked to your phone number);
• Process your membership subscription, benefit verification, and related customer service requests;
• Send necessary service notifications (such as subscription expiration reminders);
• Conduct data analysis and product improvement, and safeguard the security and stability of the service.

3. Sharing, Transfer, and Disclosure of Information

We do not sell, rent, or illegally transfer your personal information. We may share or disclose information only in the following circumstances:

• Legal requirements: When required by laws, regulations, or competent authorities;
• Protecting legal rights: When necessary to protect our or others' legal rights, property, or safety;
• Service providers: Third-party providers engaged for cloud computing, SMS, push, and similar services. We provide them only the minimum information necessary and require them to assume confidentiality and security obligations;
• With your consent: After obtaining your explicit consent.

4. Storage and Protection of Information

4.1 Storage Location and Period

We store your personal information within the territory of the People's Republic of China. We retain your information only for as long as necessary to achieve the purposes of the service, unless otherwise required by law. After you delete content or deregister your account, we will delete or anonymize the relevant data in accordance with the law.

4.2 Local-First Storage

The App follows a “local-first” design principle. Your emotion records, reflection journals, and ritual data are primarily stored locally on your device, and are uploaded to the server only when you actively use features that require the network (such as signing in, submitting postcards, or verifying subscriptions).

4.3 Security Measures

We use industry-standard security measures including TLS transport encryption, access control, least privilege, and log auditing to protect your information. However, no security measure can guarantee absolute security. Please take good care of your device and account.

5. Your Rights

• Access and correction: You can view and modify your nickname and other profile information in the App;
• Deletion: You can delete content you have created, or contact us to delete personal information related to you;
• Withdrawing consent: You can turn off or withdraw authorization for related data collection and use at any time;
• Account deregistration: You can apply to deregister your account by contacting us. After deregistration, we will delete or anonymize your personal information (unless otherwise required by law);
• Complaints and suggestions: You can raise concerns or complaints through the contact information in Section 10, and we will respond promptly.

6. Protection of Minors

This App is primarily intended for users aged 14 or above. If you are a minor under 14, please use the App with your guardian's accompaniment and consent. We do not knowingly collect personal information of children. If we inadvertently collect a child's personal information, we will delete it promptly.

7. Health Disclaimer

The sleep-companion and emotion-recording features of this App are for personal record-keeping and auxiliary reference only, and do not constitute any medical diagnosis, treatment plan, or advice. If you or your family members have sleep disorders or mental health concerns, please consult a qualified medical institution promptly.

8. Changes to This Policy

We may revise this policy from time to time in response to changes in laws and regulations, product adjustments, or business needs. For material changes, we will prominently notify you in the App or through other means. The revised policy takes effect from its stated effective date. Please review it regularly.

9. Governing Law and Dispute Resolution

This policy is governed by the laws of the People's Republic of China. Disputes arising from this policy or the App service shall be resolved through friendly negotiation. If negotiation fails, either party may file a lawsuit with a competent court at the location of the App operator.

10. Contact Us

If you have any questions, comments, or suggestions regarding this policy or the processing of your personal information, please contact us through the in-App feedback channel. We will respond within 15 working days of receiving your request.
