This Privacy Policy explains what information Yueban ("the Platform") collects when you use our website and related services, how we use and store that information, and the rights you have over your own data. By using the Platform, you acknowledge that you have read and agree to this policy.
When you register an account, we collect your phone number and verify that you control it via an SMS one-time code. Once your account is created, we store basic account information such as your role, balance, and settlement currency, along with any optional details (e.g. a display name) you choose to add.
We do not require identity documents unrelated to core account functionality.
To understand how features are used, diagnose issues, and improve the product, we use PostHog to record partially anonymized or de-identified browsing and interaction events - such as pages visited, features used, and device/browser type. This data is used for product analytics only and is not used to serve third-party advertising.
Cryptocurrency payments are processed through our third-party payment gateway, NOWPayments. We record order IDs, amounts, and transaction status for reconciliation and support purposes.
We never handle or store your wallet's private keys; the on-chain transfer itself happens between your wallet and NOWPayments, not through the Platform.
Profile gallery photos, videos, avatars, and cover images, as well as other images you or an administrator upload (such as a support QR code), are stored using Cloudflare R2 object storage and are only used to render the corresponding feature, not for any purpose beyond what this policy describes. In some environments, for development/testing purposes, the displayed version of this media may be replaced with placeholder content - this only affects what is shown publicly, not the stored original files.
To help keep transactions safe, the Platform offers a customer reputation lookup and blacklist-exposure feature: negative records associated with a phone number may be publicly displayed or looked up by profile owners/administrators. If you believe you were listed in error, you may contact us through the channels at the bottom of this site and we will review it.
We retain account and transaction records for as long as necessary to keep your account secure, resolve disputes, and meet legal obligations. Key administrative actions are recorded in an audit log for security traceability; retention periods vary by record type.
You have the right to know what information the Platform holds about you, and may request to access, correct, or delete your account information via the contact channels at the bottom of this site. We will process verified requests within a reasonable time.
The Platform uses a small number of cookies to keep you signed in and remember your language preference. We do not use cookies for cross-site tracking or third-party advertising.
We use access controls and operational audit logging to help protect your information. No method of transmission over the internet is completely secure, and we continue to improve our security practices to reduce risk.
If you have any questions about this Privacy Policy or your account information, you can reach us through the official contact channels shown at the bottom of this site (WeChat, Telegram, Twitter/X, or email).
We may update this Privacy Policy from time to time. Updated versions will be posted on this page with a revised update date. We encourage you to review this page periodically.
