Introduction

100 Feed (“we,” “our,” or “us”) is a product developed and operated by Jiacheng Wang. When you use our services, we may collect and use certain information about you. This Privacy Policy explains how we collect, use, store, and share such information, and how you can access, update, manage, and protect it.

By using or continuing to use our services, you acknowledge that you have read, understood, and agreed to this Privacy Policy.

If you have any questions regarding this Privacy Policy, please contact us at support@100feed.com.

1. Information We Collect

We or our third-party partners may collect, store, and use certain information related to you when providing our services. If you choose not to provide certain information, you may be unable to register as a user, access certain features, or experience the full functionality of our services.

We may collect the following types of data:

• Account and authentication information (e.g., login credentials, identifiers used for syncing data);
• Usage and diagnostic data (e.g., app usage frequency, crash logs, anonymized analytics);
• Subscription and purchase verification data (e.g., in-app purchase receipts, anonymous identifiers).

2. Storage of Information

2.1 Storage Method and Retention Period

We store your information securely using local storage (such as app cache), databases, and server logs. We retain personal information only for as long as necessary to fulfill the purposes described in this policy or as required by applicable laws and regulations. When the retention period expires, your data will be deleted or anonymized.

2.2 Storage Location

All personal data collected within mainland China is stored in China in compliance with applicable laws and regulations. We currently do not transfer or store personal information outside of China. If cross-border transfer becomes necessary in the future, we will inform you of the purpose, recipient, and potential risks, and obtain your explicit consent before proceeding.

2.3 Notice of Service Termination

If our products or services are discontinued, we will notify you via in-app messages, announcements, or other appropriate means, and will delete or anonymize your personal data within a reasonable period, unless otherwise required by law.

3. Information Security

We adopt a variety of technical and organizational measures to protect your data from loss, misuse, unauthorized access, or disclosure. For example, we use encryption technologies (such as SSL/TLS) to protect data transmission. However, please understand that no method of data transmission or storage on the internet can be guaranteed to be 100% secure. You acknowledge that network failures or security issues beyond our control may occur.

4. How We Use Your Information

• To provide, maintain, and improve our services;
• To verify identity, provide customer support, enhance security, and prevent fraud;
• To design new features and improve existing services;
• To understand how users interact with the app and personalize the user experience (e.g., language settings, preferences);
• To evaluate and enhance app functionality and performance;
• To manage software verification and updates;
• To invite you to participate in surveys related to our products and services.

5. Information Sharing

We do not sell your personal information to any third party. If it becomes necessary to share or transfer your data—for example, to enable specific features or as required by law—we will first obtain your explicit consent or ensure the third party has obtained such authorization, and we will require them to comply with strict data protection standards.

Third-Party SDK: RevenueCat

We use a third-party service provider, RevenueCat (provided by RevenueCat, Inc.), to manage in-app purchases and subscriptions. RevenueCat may process certain data, such as purchase receipts, subscription status, app version, and an anonymized app-specific user ID, solely for the purpose of verifying and restoring purchases.

RevenueCat does not process or store sensitive payment data such as credit card numbers or billing addresses. All payment-related data is handled directly by Apple’s in-app purchase system.

For more details on RevenueCat’s privacy practices, please refer to its official Privacy Policy: https://www.revenuecat.com/privacy

We will never share personally identifiable information (such as your name or email address) with any partner unless you have explicitly authorized us to do so or as required by law.

If our business undergoes a merger, acquisition, or asset transfer, we will continue to protect your personal information or ensure the new controller maintains equivalent protection standards.

We may disclose your information without prior consent only in the following cases as permitted by law:

• For national security or defense purposes;
• For public safety, public health, or significant public interests;
• For criminal investigations, prosecutions, or enforcement of judgments;
• To protect the life, property, or other significant legal rights of you or others when it is difficult to obtain consent;
• When information is voluntarily made public by the individual;
• When information is collected from legitimate, publicly available sources.

6. Your Rights

During your use of our services, you may access, modify, or delete your personal information through the app’s settings or features where applicable. You may also contact us directly to exercise the following rights:

• Request access to or a copy of your personal information;
• Request correction or deletion of your personal information;
• Withdraw previously granted consent;
• Request data portability.

To exercise your rights, please contact us via support@100feed.com. We will respond within 15 business days of receiving your request. If your request is complex or requires additional verification, we will inform you of the reason and expected processing time.

7. Policy Updates

We may revise this Privacy Policy from time to time to reflect changes in our services or legal requirements. When updates occur, we will notify you by updating the “Last Updated” date on this page or through in-app notices. If the changes significantly affect your rights, we will seek your consent again before implementing them. Continued use of our services after such updates constitutes your acceptance of the revised Privacy Policy.

8. Protection of Minors

We encourage parents or guardians to guide minors under the age of 18 in using our services. If you are under 18, please use this app under the supervision and consent of your parent or guardian. If we become aware that a minor has provided personal information without proper consent, we will take reasonable steps to delete such data as soon as possible.
