FUFU Journey

• Apple ID Authentication (optional). Signing in with Apple is optional. Most learning features work signed-out. When you do sign in, we receive a unique Apple-provided user identifier and, if you choose to share it, your email address. We never receive your Apple ID password.
• Purchase Information. When you buy a Fufu Coin pack (1, 5, or 10 coins) or activate a monthly/yearly subscription, Apple processes the payment. We store the transaction ID and product ID solely to credit your account. We do not have access to your payment card, bank, or billing details.
• Study Log. When you use the “Fufu Insights” AI reading aid, the resulting interpretation text and the lesson context are stored on our servers, associated with your account, so you can revisit them later. We keep at most 20 records per user; older records roll off automatically.
• Conversational Practice usage counter. When you use “Conversational Practice” with a classical persona (Confucius, Laozi, Mencius, Sunzi, etc.), we increment a server-side daily call count tied to your account for rate-limiting and fraud prevention. The count is a number; the message content is not stored.
• Learning Progress (cross-device sync). Course completion status, quiz scores, and total study time are stored locally on your device and synced across your other Apple devices via Apple's iCloud Key-Value Store, using the same Apple ID you signed into iCloud with. We do not receive or store this progress on our servers.
• Fufu Energy. Your daily Fufu Energy balance (a learning-pace meter that resets at midnight) is stored locally on your device.
• Milestone Claim Records. When you receive one-time bonuses (new-user gift, first-subscription gift, first-lesson-per-classics-course gift), we record the milestone key on the server to prevent the same bonus from being granted twice. No content is stored beyond a string identifier.

• To provide and maintain your account and learning services
• To process in-app purchases and manage your Fufu Coin balance
• To store your Study Log so you can revisit AI-assisted readings
• To sync your learning progress across your Apple devices via iCloud
• To enforce fair-use limits on Conversational Practice
• To improve the quality of our app and services

We do not sell, trade, or share your personal information with third parties, except:

• Apple. Payment processing through the App Store; iCloud Key-Value Store synchronization for learning progress.
• DeepSeek API. Requests powering Fufu Insights and Conversational Practice are sent to the DeepSeek AI service. These requests contain only the lesson content and your conversational input; they do not include your name, email, Apple ID, or other personal identity information.

Your account data, Study Log, daily usage counters, and milestone claims are stored on secure servers (Neon PostgreSQL hosted on AWS). All data is transmitted using industry-standard encryption (HTTPS/TLS). JWT authentication tokens are stored in the iOS Keychain on your device. Learning progress synced via iCloud is encrypted by Apple in transit and at rest.

• Study Log: capped at 20 records per user. You can delete individual records at any time from within the app.
• Conversational Practice daily counter: retained briefly for rate-limiting purposes; older counters are pruned automatically.
• Account deletion: you can delete your account and all associated server-side data (account, credits, transactions, Study Log, daily counters, milestone records) directly within the app. iCloud-synced learning progress can be cleared from your Apple device settings or by erasing the app.

FUFU Journey is not directed at children under 13. We do not knowingly collect personal information from children. If you believe a child has provided us with personal information, please contact us so we can remove it.

We may update this Privacy Policy from time to time. Material changes will be posted within the app or on our website. Continued use of the App after a policy update constitutes acceptance of the revised policy.
