Privacy Policy.

1. Operator and scope

Youhua is run by the individual operator shaolong yu. This policy applies to the Youhua iOS app, related backend, and this website. Contact the operator about privacy and personal information rights through the support channel listed here: support@youhua.me.

You must meet the requirements of local law and the app store's age rating. Obtain guardian consent where legally required. Contact support about minors' personal information so we can investigate and respond.

2. Information we process and why

We use the profile information you provide to personalize content discovery and help you find interesting topics. You can edit it in your profile. Discovery results depend on available content.

Mutual follows can send original voice recordings of 1–60 seconds. Microphone permission is requested when recording. Audio is held in private storage and playable only by authorized conversation participants. We do not transcribe voice, analyze its content, assess its content risk, or send it to AI or content review services. The server checks only conversation permissions, attachment format, size, and duration. We do not access device contacts, precise location, or advertising identifiers and do not use advertising tracking SDKs. Only images you select are processed. Faces, text, and other identifiable image details may still be personal information. This website uses no analytics scripts, advertising, or non-essential cookies.

3. AI chats, memory, and content review

Platform AI topics: Youhua generates batches of public topics using AI, reviews them, and displays their source. Generation uses only previous platform AI topics, not your profile, user-published topics, or private chats. If you select a topic and send a message, processing follows the AI chat rules below.

AI chats: After you agree to AI conversation processing, the everyday companion chat sends your current input and images, up to the most recent 40 completed turns of that conversation (retaining only necessary recent images), public topic text you explicitly quote, and saved long-term memories filtered by topic and validity to a third-party AI service for replies. AI topic chats in Inbox use only that topic's original topic, current message and images, and up to 40 recent completed turns. They do not read or organize long-term memories. Separate topics and the everyday companion do not automatically mix contexts. When bringing an AI topic or personal chat to Youhua, you can explicitly select up to 20 turns. Preview reads only records you may access and does not call the model. Confirming “Include and continue chatting” saves a snapshot of selected text on the server and sends it, plus your added text, to the third-party AI service. The original AI topic text may also be included. Images, voice messages, unselected history, and automatic summaries are excluded. These records continue the everyday chat. If withdrawal, source deletion, or relationship restrictions make original content inaccessible, the corresponding snapshots are no longer displayed or supplied to future AI replies. Deleting the source topic chat also clears linked snapshots; deleting the receiving chat clears snapshots with its turns. Included history does not independently generate long-term memory; subsequent everyday chat follows normal memory rules. We do not automatically send personal private messages as AI chat context.

Memory: After consent to AI processing, only the everyday companion in Youhua organizes long-term memories through a third-party AI service, using relevant conversation text after the first 40 successful turns and every 20 additional turns. Saved memories support later replies. There is currently no separate memory switch. View, edit, or delete entries in “Memories.” Withdrawing AI consent stops new memory organization and use but does not automatically delete saved memories.

Content review: To filter prohibited content, we send profile text, avatars, topics, moments, personal text messages and attached images, AI inputs and replies, and memories requiring review to a third-party AI service. Review may happen before publication or delivery. If processing fails or approval cannot be confirmed, content may temporarily be unavailable for publication or delivery. The operator may examine reported content and handle it manually when necessary.

These requests primarily contain content and necessary context. We do not intentionally attach Apple sign-in credentials, email addresses, or credit ledgers. However, identity, health, location, or other information you include in text or images is transmitted with that content. Do not upload passwords, identity documents, financial account information, sensitive health information, or others' personal information without permission.

AI service recipient: Youhua uses the DeepSeek Open Platform API (杭州深度求索人工智能基础技术研究有限公司). Its public privacy contact is privacy@deepseek.com and platform support is api-service@deepseek.com. It receives the chat inputs, necessary context, images, and content for review described above to generate replies, organize memories, and review content safety. Processing may occur in mainland China and may involve cross-border transfers. Youhua uses the standard Open Platform terms without a separate zero-retention, no-training, or synchronized-deletion agreement.

A provider's privacy policy for its own users does not replace Youhua's notice to downstream users. Youhua does not promise specific API input/output retention periods, zero retention, or exclusion from training. Do not submit content you do not want this recipient to process. Submit access, correction, deletion, or other rights requests through support@youhua.me. After verification, Youhua requests necessary provider assistance under applicable rules and section 3.5 of the Open Platform terms. We cannot guarantee withdrawal of already-sent content or immediate deletion of provider data. Material processing changes will be communicated, with renewed consent where required.

Turn off AI conversation processing in Me → Settings, or delete chats or memories. If you do not agree to third-party review of social content, do not submit it. You can still read this website, contact support, or delete your account. Withdrawing consent does not reverse earlier processing. Plus renewal can be canceled separately through Apple subscription management.

4. Other recipients and visibility

• Alibaba Cloud: Provides Singapore cloud servers and private object storage for databases, images, and necessary backups. The backend checks image access rights. Storage buckets do not allow anonymous reads.
• Apple: Provides sign-in, in-app purchases, subscriptions, transaction verification, and system notifications when enabled. Delivery involves device tokens, conversation identifiers, and sender nicknames and previews enabled under this policy. Apple processes information under its privacy information.
• Other users: Your published topics, profile, and moments appear to users with access according to app visibility rules. Personal messages appear to conversation participants. Choose public content carefully. We cannot recall all copies saved or captured by others.
• Legally required recipients: Relevant records may be disclosed as needed under applicable law, lawful requests, or to protect personal and service safety.

We do not sell personal information or use it for cross-app advertising tracking. 阿里邮箱（中国站免费版） provides email delivery or storage for support, processing your email address, message, and attachments to answer questions and handle requests. Having servers in Singapore does not mean all recipients are there. Processing locations may differ from where you live.

5. Retention, deletion, and account closure

During normal account use, we retain profile data, content, and free credit records needed for the relevant features. You can delete AI chats, memories, and moments. Expiry or removal from display does not necessarily mean immediate physical deletion from databases. Images not referenced by valid content become eligible for cleanup 30 days after upload. Images marked for deletion are cleaned asynchronously, with retries after failure.

After you verify your identity again with Apple in the app and choose “Permanently delete account,” we revoke Youhua's Apple sign-in authorization, invalidate sessions, clear profile data, delete AI chats and memories, withdraw your topics, moments, personal message text and image references, and arrange media cleanup. Your Youhua account cannot be restored through this process.

We may retain the minimum records needed for transactions, refunds, reports, safety restrictions, and audits, plus conversation structures with content cleared. These currently have no universal automatic expiry cleanup. The operator reviews them manually at least quarterly. Records still needed for subscriptions, refunds, disputes, or legal retention obligations have their reasons, scope, and retention periods documented. Records without a remaining basis are deleted or de-identified. Send requests through support@youhua.me. Where immediate deletion is unavailable, we explain specific reasons and next steps. We do not promise all backend data will be deleted immediately or within a single fixed period.

Historical or manual backups for recovery have restricted access and are not used for everyday display. Their necessity and cleanup are included in quarterly manual reviews, without a promised universal automatic rotation period. Confirmed deletion requests must be reapplied after recovery. Deleting local records cannot synchronously erase data already received by third parties. We assist with provider data requests after verifying identity.

Before deletion, save needed data and cancel unwanted Apple subscriptions. Account deletion does not automatically cancel renewal. Remaining credits and benefits do not transfer to a new account. See Usage and purchases.

6. Your choices and rights

• Edit your profile in Me. In Settings, choose “Export my data” to export available text and records. This is not a complete archive of all images or backend operational records.
• Delete conversations, memories, and moments. Turn off AI conversation processing to stop new chat and memory processing. Disable notifications or change Show Previews in iOS settings.
• Verify your identity and delete your account in Me → Settings → Delete account. Contact support if you cannot sign in.
• Use support@youhua.me to request access, correction, deletion, restriction, copies, other applicable rights, or to make a complaint. We may request the minimum identity verification needed and respond within applicable legal deadlines. If we cannot meet all of a request, we explain why and available remedies.

We will not ask you to email Apple passwords, verification codes, private keys, or complete bank card information. This policy does not reduce statutory rights. You may also complain to the competent data protection authority.

7. Security and policy updates

Production services use HTTPS, media access is authorized, and access to sign-in and service credentials is restricted. We take safeguards appropriate to the risks, but transmission and storage still carry risks. For data incidents requiring notice, we respond and notify as applicable law requires.

We update this page and notify you in the app or through suitable channels when adding recipients, changing purposes, or making other material changes. Processing requiring renewed consent proceeds after consent is obtained. The version and date appear at the top of this page.
