Effective date: July 6, 2026
Scope: This document applies to the CHHES i OS App, Android App, and all CHHES versions available on app stores or mobile manufacturer channels, including Huawei, Xiaomi, OPPO, vivo, Honor, Samsung, and App Bao. In-app messaging rules for the website, We Chat mini-programs, or other platforms can also follow this document.
To deliver push notifications—including order alerts, shipping updates, system notices, promotional messages, and customer service messages—this app uses DCloud uni Push, and may also invoke the offline push SDK provided by your device manufacturer. On i OS, system notifications may additionally be sent via Apple Push Notification service (APNs) and other system channels, depending on i OS permissions and display settings.
Push notifications are not a prerequisite for using the CHHES App. After disabling notification permissions, you can still use all core features such as browsing, ordering, payment, after-sales service, and customer support, but you may not receive timely order, shipping, event, system, or customer service notifications.

The above information is used solely to enable push notifications, offline push delivery, notification receipt confirmation, message analytics, and service optimization. It will not be used for any purpose unrelated to push notifications. We will not send sensitive personal information such as payment passwords, complete ID numbers, or full bank card numbers via push notifications. Promotional, discount, or marketing notifications will only be sent in compliance with applicable laws, regulations, and platform rules. You can disable or adjust these notifications through your system settings or within the app.
You can disable notification permissions through your device's system settings. After disabling them, you can still use all other app features normally, but you may not receive order, shipping, promotional, system notifications, and other messages in a timely manner. Steps vary by device, but the typical path is Settings > Notifications > CHHES > Allow Notifications. On some Android devices, you can also manage this through App Management, Permission Management, Notification Management, or your phone manufacturer's security center.
For personal information processing rules, third-party SDK sharing details, user rights, and contact information related to push notifications, please also refer to the Privacy Policy, Permission Request Description, and Login and Account Security Description. If this description conflicts with specific event rules or system authorization pop-ups, the description that better protects user rights and complies with applicable laws, regulations, and platform rules shall prevail.
