Privacy Policy

This Privacy Policy applies to the Yuskai iOS application, Yuskai's public legal and support pages, and the services used to provide Jobs, Housing, Marketplace, saved listings, messaging, reporting, blocking, and moderation features.

Yuskai is operated by Zekai Yu. In this policy, “Yuskai,” “we,” “us,” and “our” refer to the Yuskai service and its operator.

The information we handle depends on the features you choose to use. You may browse some nearby content without creating an account, but posting, saving, messaging, reporting, and blocking require authentication.

Account and profile information

• Email address, authentication credentials, authentication identifiers, and session information processed when you create or access an account.
• Your Yuskai user ID, display name, account status, locale, and profile image path if profile images are supported and you choose to add one.
• Account creation, update, restriction, suspension, and deletion timestamps needed to operate and secure the service.

Listings and other content you provide

• Listing titles, descriptions, category, location name, coordinates, status, and publication dates.
• Job information such as employer name, pay range, employment type, education or experience requirements, and whether training is provided.
• Housing information such as housing type, monthly price, currency, and availability date.
• Marketplace information such as price, currency, item condition, and uploaded listing images.
• Optional free-form text may contain information you choose to include. Please do not post sensitive personal information that is not necessary for the listing.

Messaging and interaction information

• Conversation participants, messages, message timestamps, client message identifiers used to prevent duplicate delivery, and read state.
• Listings you save or remove from saved items.
• Accounts you block or unblock.

Safety, reporting, and moderation information

• Reports you submit about a listing, account, or message, including the selected reason and optional details.
• Automated review signals, moderation status, staff review decisions, action reasons, and operational notes.
• Relevant listing, profile, or message context needed to investigate reports, prevent abuse, and enforce Yuskai rules.

Location information

If you grant location permission, Yuskai receives coordinates from your device to find nearby listings and identify a nearby city. The app currently requests approximately hundred-meter accuracy, but coordinates sent to the service may still qualify as precise location under platform definitions. When you publish a listing, its submitted location and coordinates are stored with that listing. Coordinates used only for a nearby search are processed to return results; Yuskai does not currently maintain a separate persistent search-history feature.

Support and technical information

• Your email address and the contents of messages you send when requesting support or exercising a privacy choice.
• Request identifiers, timestamps, authentication outcomes, error information, and service logs used for reliability, security, and troubleshooting.
• Infrastructure providers may process standard connection information, such as an IP address and request metadata, to deliver and secure the service.

• Directly from you when you create an account, publish or edit a listing, upload an image, send a message, save content, block an account, file a report, contact support, or request deletion.
• From your device when you grant location permission or make an authenticated request to the service.
• From your use of Yuskai when the service creates delivery, read-state, safety, moderation, and operational records.
• From service providers that support authentication, database hosting, storage, realtime message events, email, and application hosting.

• Create and authenticate accounts and maintain account sessions.
• Publish, search, sort, display, update, close, review, and remove listings.
• Show nearby content and associate a location with a listing you choose to publish.
• Store and deliver listing images and private messages.
• Maintain saved listings, read state, blocking, and other user-requested features.
• Detect prohibited or suspicious content, route content for review, investigate reports, and enforce safety rules.
• Prevent duplicate operations, fraud, spam, account misuse, and unauthorized access.
• Operate, debug, secure, and improve the reliability of Yuskai.
• Respond to support, privacy, legal, and safety requests.
• Comply with applicable law and protect users, Yuskai, and the public.

Yuskai uses rule-based automated screening on certain listing and message text. Content matching a high-risk prohibited pattern may be rejected. A listing matching a suspicious pattern may be hidden from public results and placed into the staff review queue. Staff can review context and approve, reject, hide, restore, restrict, or otherwise act on content as permitted by Yuskai's moderation workflow.

Automated screening is used for safety and service integrity. If you believe a decision was made in error, contact us using the address at the end of this policy.

We share information only as needed to operate Yuskai, comply with law, protect the service, or carry out a request you make.

• Other users receive information you intentionally publish, such as listing content, images, location labels, and the display information needed to use the service.
• Conversation participants receive messages and related conversation information. Private messages are not public, but authorized moderation staff may access relevant context when investigating a report or safety issue.
• Supabase provides authentication, PostgreSQL database infrastructure, file storage, and realtime delivery infrastructure.
• Cloud hosting, networking, email, and operational providers process information necessary to run, secure, and support the service.
• Information may be disclosed when reasonably necessary to comply with law, respond to lawful process, protect safety or rights, investigate abuse, or address an emergency.
• If Yuskai is reorganized or transferred, information may be transferred as part of that transaction subject to this policy and applicable law.

We require service providers that receive personal information to use it only for the services they provide and to maintain the same or equivalent protections described in this policy.

Listings are designed to be visible to people using Yuskai. Do not include private contact credentials, government identifiers, passwords, banking credentials, or other sensitive information in a listing, image, message, or report unless it is genuinely necessary and safe to share.

Messages are visible to conversation participants and may be made available to authorized moderators when required to evaluate a report, a safety concern, or a violation of Yuskai rules.

We retain account and service information for as long as reasonably necessary to provide Yuskai, keep the service secure, resolve disputes, investigate abuse, and meet legal obligations. Different records may be retained for different periods based on their purpose.

You can initiate permanent account deletion inside the iOS app from Me → Settings → Delete Account. When deletion completes:

• Your Supabase authentication identity is deleted.
• Your profile name and personal profile information are removed or anonymized.
• Your listings are removed from public access and their user-provided text, category details, location, and images are deleted or redacted.
• Your sent message text is removed while limited non-personal tombstone records may remain to preserve conversation integrity and safety history.
• Your saved listings, block relationships, media metadata, and staff access, if any, are removed.
• Limited anonymized identifiers, report records, moderation records, or security records may remain where reasonably necessary for integrity, fraud prevention, safety, dispute resolution, or legal compliance.

You may also contact us if you cannot access the in-app deletion control. Deleting the app from your device does not by itself delete your Yuskai account.

• Location: decline or revoke location permission in iOS Settings. Some nearby-search and publishing features may not work without it.
• Listings: edit or close eligible listings through My Listings. Account deletion removes your listings as described above.
• Saved content: add or remove saved listings at any time.
• Safety: report listings, accounts, or messages and block or unblock other accounts using the controls in Yuskai.
• Account: sign out or permanently delete your account from Settings.
• Privacy requests: depending on applicable law, you may request access, correction, deletion, or other available controls by contacting us.

Yuskai uses technical and organizational measures intended to protect information, including authenticated API access, restricted staff roles, private realtime channels, database constraints, and controlled storage access. No network, service, or storage system can be guaranteed completely secure. Protect your password and notify us if you believe your account or information has been compromised.

Yuskai is not directed to children under 13, and we do not knowingly collect personal information from children under 13. If you believe a child has provided personal information to Yuskai, contact us so we can investigate and take appropriate action.

Yuskai and its service providers may process information in the United States and other locations where infrastructure providers operate. Privacy and data-protection rules in those locations may differ from those where you live. We use appropriate safeguards as required for the information and services involved.

We may update this policy when Yuskai's features, providers, or legal obligations change. The “Last updated” date identifies the current version. If a change materially affects how we handle personal information, we will provide additional notice when appropriate.

For privacy questions, account-deletion assistance, safety concerns, or requests about your information, contact Yuskai's operator, Zekai Yu, at yu.zekai@icloud.com.
