Read in English — Terms of Service
1. Service and account
Beijing Huo Du Du Technology Co., Ltd. provides self-produced learning materials, layered reading, audiovisual learning, action plans, reflection and AI assistance. Phone verification supports personal record synchronization. Protect your credentials and do not impersonate others.
2. Content and AI
Our learning explanations and reconstructed materials are self-produced. Referenced original works, titles and rights remain with their owners; our materials do not replace original works. You retain rights to your notes and inputs and authorize necessary processing to provide requested services. Do not submit unlawful, infringing, fraudulent or privacy-invasive material, disrupt services or bypass access controls. AI output is for learning and is not guaranteed accurate or suitable in every situation.
3. Pricing, access and refunds
Basic reading is available and non-members receive a daily AI coaching allowance. Trial access and its expiry are shown in the app. Purchasing is possible only through an enabled purchase flow; unavailable flows do not charge you. Under the current product model, monthly and yearly passes are one-time purchases without automatic renewal. Price, duration and benefits must be shown before purchase; listed but unavailable products are not purchasable. iOS digital purchases use Apple in-app purchasing without external payment redirection. Request Apple transaction refunds at reportaproblem.apple.com under Apple’s rules. Contact dodofun@126.com for entitlement or payment issues. Account deletion does not automatically request a refund; unpaid orders do not grant paid access.
4. Privacy, termination and contact
Processing follows our Privacy Policy and separate AI permission. Delete your account in Settings to end personal service. Maintenance, network issues or force majeure may interrupt service; we will make reasonable repairs without excluding your statutory rights. Contact dodofun@126.com to resolve issues. Mainland Chinese law applies, with disputes handled by a court with lawful jurisdiction. Operator and filing details appear in our Privacy Policy.
