Privacy Policy

LinkHuaren, the iPhone app and the website linkhuaren.com, is operated by Supret LLC ("we"), which is responsible for the personal information described here.

1. What we collect

• Account: your Sign in with Apple identifier (and name/email if you share them), your verified phone number, handle, profile details you add (photo, bio, birthday, gender, interests, language preference).
• Content: posts, listings, comments, messages, photos, help requests, feedback, and reports you submit.
• Verification applications (optional): if you apply for a tag, the papers that application asks for. 实名认证 (identity): photos of the front and back of an ID and a selfie holding it. 金牌经纪人 (agent): your licence card and number, brokerage and service areas. 认证商家 (business): storefront photos or a document naming the owner. They are stored privately and reviewed by LinkHuaren staff; no outside verification vendor sees them.
• Purchases: when you buy credits (点数) with In-App Purchase, Apple takes the payment and sends us the transaction record (product, transaction id, date, refunds). We never see your card or Apple account details. Credits you earn, buy and spend are recorded on your account.
• Location: only if you allow it. Used to find nearby content and, on a listing you post, at the precision you choose (see §4). Showing your city on your profile is off until you turn it on.
• Voice calls: calls are carried by Stream between the two people in a chat, and only inside a chat both have accepted. We do not record calls. To ring your phone while it is locked, Stream holds a VoIP push token for your device.
• Device & usage: app version, device model, a device identifier used to connect calls, a push notification token (if you allow notifications), crash reports, analytics events, and session replay (screen recordings of your app usage with text inputs, images and sensitive screens masked).
• Website: linkhuaren.com sets a sign-in cookie when you sign in there, and records page views and clicks with PostHog under a cookie identifier (it honours your browser's Do Not Track setting). Cloudflare, which hosts the website, processes visitors' IP addresses and request details to deliver pages and stop abuse.
• Listing views: when you open someone else's listing, we record that you viewed it, at most once per listing per day, to count its views. The seller sees a total, never who viewed it. The record of who viewed what is deleted after three days; only the daily totals are kept.
• From automated systems: moderation results on your content. Every photo you upload (listing, post, profile and chat photos) is checked by Claude, an AI model from Anthropic, before anyone but you sees it, and every new or edited post, listing, comment and bio is reviewed by Claude after a keyword screen. A refused photo is removed and you are told why. Text Claude flags goes to LinkHuaren staff; a serious case is hidden until they look, and you are told.

2. How we use it

To run the App (accounts, feeds, listings, messaging, calls, credits, and notifications, including a daily digest of your listings' views and a daily local-news alert, each of which you can turn off in Settings); to keep it safe (moderation, anti-fraud, one-account-per-phone-number, and the optional verification tags); to fix and improve it (crashes, analytics, replay); to comply with law. We do not sell your personal information and do not use cross-app tracking (no ATT prompt — there's nothing to ask about).

3. Who processes it for us

Supabase (database, storage, auth) · Cloudflare (hosting linkhuaren.com, security) · Stream (messaging, voice calls & call push) · Apple (sign-in, push notifications, In-App Purchase) · Twilio (SMS verification) · PostHog (analytics, error tracking & session replay) · Anthropic (checking every uploaded photo, reviewing the text of posts, listings, comments and bios, suggesting categories, and rewriting public news stories into plain 简体) · Sightengine (image moderation, only if we switch it on; not used today). Each receives only what its job requires. Verification papers are reviewed by LinkHuaren staff and go to none of these.

4. What others see

Your handle, profile, and public posts/listings are visible to signed-in users. On linkhuaren.com, anyone can read listings and community posts without signing in, with the poster's display name and photo and a post's top comments, and search engines may list them; your handle, profile page, phone number and a listing's exact address are shown only to signed-in users. Your phone number is shared only in the contexts you use it for member-to-member contact. Your birthday and gender are not public. Blocked users can't see your profile or content or message you. A listing's view count is a number; nobody sees who viewed it.

Verification. An approved application shows its tag (实名认证, 金牌经纪人, 认证商家) on your profile and listings. The papers themselves are never shown to anyone but the reviewing staff. An approved agent's brokerage (所属公司) and service areas (服务区域) are public, and an approved business has a public page with its name and listings.

Your location on a listing is as precise as you choose. Every listing asks for one, and the same screen asks how much of it readers get: the exact point, an approximate area of roughly 500 m, or nothing at all. Exact publishes the address you picked to every signed-in reader. Approximate publishes only the neighbourhood. Hidden publishes no place name.

We keep the point you picked either way, and use it only to answer "is this listing within N miles of me" — a question whose answer reveals nothing beyond the radius you were already told about. We do not verify that any address is yours.

5. Retention & deletion

Delete your account in the app: Me › Settings › Delete account (我的 › 设置 › 删除账号), or request it at linkhuaren.com/delete-account. There's a 30-day grace period (sign back in to restore), then data is permanently deleted or de-identified; a small set of records may be kept where the law requires (e.g., moderation/safety records). Content you deleted individually is removed from serving immediately. Purchase records are kept as long as tax and accounting law requires. Verification papers (ID photos, the selfie, licence and business papers) are deleted 30 days after your application is decided (approved, rejected or withdrawn), and when your account is permanently deleted; we keep the decision and the details you typed.

6. Children

The App is for people 13 and older. We don't knowingly collect data from children under 13 — if a birthday shows under 13, the account is closed and data deleted. Parents: contact support@linkhuaren.com.

7. Your choices & rights

Notification types, analytics opt-out, location sharing, and language are controlled in Settings. Depending on where you live (e.g., California), you may have rights to access, correct, or delete your data — email support@linkhuaren.com and we'll honor them.

8. Changes & contact

Material changes are announced in-app and the version you accepted is recorded on your account. Contact: support@linkhuaren.com.
