Hujue Privacy Policy

1. Introduction

This Privacy Policy ("Policy") explains how Hujue ("Company", "We", "Us", "Our") collects, uses, discloses, and protects information in connection with the Hujue mobile application (the "App"), in compliance with applicable United States privacy laws, including the California Consumer Privacy Act (CCPA), California Privacy Rights Act (CPRA), Children's Online Privacy Protection Act (COPPA), and other relevant federal and state regulations.

Hujue is designed as an offline-first note-taking application that does not require user account registration or login. Our primary commitment is to protect your privacy and ensure that your personal information remains secure and under your control at all times.

By using the App, you acknowledge that you have read and understood this Policy and agree to the collection, use, and disclosure of your information as described herein. If you do not agree with this Policy, you must not use the App.

2. Information We Collect

2.1 Information You Provide Voluntarily

Since the App does not require account registration, we do not collect personal identifying information (PII) such as your name, email address, phone number, or date of birth unless you voluntarily provide it to us (e.g., when contacting our support team at hujue171726310@outlook.com).

The primary information associated with your use of the App is the content you create and store within the App, including:

• Text notes, journal entries, and to-do lists
• Checklist items and their status (completed/incomplete)
• Images uploaded to the App for note-taking purposes
• Tag information used to organize your content
• User interface preferences and customization settings

All user-generated content is stored locally on your device and is not transmitted to our servers unless you explicitly export or back up your data (at which point the data is under your complete control).

2.2 Automatically Collected Information

We may collect limited technical information automatically when you use the App, solely for the purpose of improving App performance and functionality. This information does not identify individual users and includes:

• Device type, operating system version, and unique device identifiers (only stored locally)
• App usage statistics (e.g., features used, session duration) - collected anonymously and locally
• Crash reports and error logs (only if you opt to send them to us for troubleshooting)

We do not collect, track, or store your location data, browsing history, or any other sensitive personal information.

2.3 Information from Third Parties

We do not collect any information about you from third-party sources, including social media platforms, advertising networks, or data brokers.

3. How We Use Your Information

We use the information we collect for the following limited purposes, all of which are directly related to providing and improving the Hujue App:

• To provide and maintain the core functionality of the App (e.g., storing your notes locally on your device)
• To personalize your experience with the App based on your preferences
• To diagnose and fix technical issues and improve App performance
• To respond to your customer support inquiries and provide assistance
• To comply with applicable legal obligations and protect our rights and interests

We do not use your information for:

• Targeted advertising or marketing purposes
• Selling or sharing with third parties for commercial gain
• Profiling or tracking your behavior across different apps or websites

4. Disclosure of Your Information

4.1 General Disclosure

We do not sell, rent, lease, or otherwise disclose your personal information to third parties for commercial purposes. We will only disclose your information in the following limited circumstances:

• With your explicit consent: We may share your information if you specifically authorize us to do so
• For legal compliance: We may disclose your information if required to do so by law, court order, or governmental request
• To protect rights and safety: We may disclose your information to protect our rights, property, or safety, or the rights, property, or safety of others
• In connection with business transactions: If the Company is involved in a merger, acquisition, or sale of all or a portion of its assets, your information may be transferred as part of that transaction (with notice to you as required by law)

4.2 Service Providers

We may engage third-party service providers to perform functions on our behalf (e.g., technical support, app development). These service providers will have access to your information only to the extent necessary to perform their functions and are contractually obligated to protect your information and use it only for the purposes specified by us.

5. Data Security

We implement appropriate technical and organizational security measures to protect your information from unauthorized access, disclosure, alteration, or destruction. These measures include:

• Local storage encryption for all user data on your device
• Secure data transmission protocols (when applicable)
• Regular security assessments and updates to the App
• Restricted access to any collected information (limited to authorized personnel only)

However, no method of transmission over the internet or electronic storage is 100% secure. While we strive to use commercially acceptable means to protect your information, we cannot guarantee absolute security. You are responsible for taking reasonable precautions to protect your device and the data stored within the App (e.g., using device passcodes, biometric authentication).

6. Your Privacy Rights (CCPA/CPRA Compliance)

If you are a California resident, you have the following rights under the CCPA/CPRA:

• Right to Know: You may request information about the categories and specific pieces of personal information we have collected about you, the sources of that information, the purposes for which it was collected, and the third parties with whom it was shared
• Right to Delete: You may request that we delete any personal information we have collected from you (subject to certain exceptions under California law)
• Right to Opt-Out: You may opt out of the sale of your personal information (note: we do not sell your personal information, so this right applies only if our practices change)
• Right to Non-Discrimination: We will not discriminate against you for exercising your CCPA/CPRA rights (e.g., by charging you different prices or providing different services)
• Right to Correct: You may request that we correct inaccurate personal information about you

To exercise these rights, please contact us at hujue171726310@outlook.com with sufficient information to verify your identity. We will respond to your request within 45 days (or up to 90 days if necessary, with notice to you).

7. Children's Privacy (COPPA Compliance)

The App is not intended for children under the age of 13, and we do not knowingly collect personal information from children under 13. If we become aware that we have collected personal information from a child under 13 without parental consent, we will take steps to delete that information as soon as possible. If you are a parent or guardian and believe your child has provided us with personal information, please contact us at hujue171726310@outlook.com to request deletion of that information.

8. Data Retention

Since all user-generated content is stored locally on your device, you have complete control over the retention of your data. We do not retain your personal information for longer than necessary to fulfill the purposes for which it was collected, unless required by law. If you delete the App from your device, all locally stored data will be deleted (unless you have exported a backup).

Any technical information collected anonymously may be retained for a reasonable period to analyze trends and improve App performance, but will not be linked to individual users.

9. International Data Transfers

If you use the App outside of the United States, your information may be transferred to, processed, and stored in the United States. By using the App, you consent to the transfer of your information to the United States, which may have different data protection laws than your country of residence. We will ensure that any international transfers comply with applicable laws and provide adequate protection for your information.

10. Changes to This Policy

We may update this Privacy Policy from time to time to reflect changes in our practices or applicable laws. Any changes will be effective immediately upon posting the revised Policy in the App or on our website (if applicable). We will notify you of material changes by posting a prominent notice in the App or by other means of communication. We encourage you to review this Policy periodically to stay informed about how we are protecting your information.
