1. Overview of Data

To provide sign-in and account services, when you use "Sign in with Apple" or "WeChat Login", we receive and store the account-related information necessary for that purpose (see Section 2 below). Apart from that, XC Master does not collect or store any information that identifies you or your device.

2. Third-Party Login and SDKs

To support Apple and WeChat login, we use the following SDKs. We only use the information we receive to create or link your XC Master account:

(1) Sign in with Apple (iOS only)

We use Apple's Sign in with Apple SDK. We only receive the user identifier (sub) provided by Apple, and optionally the email and name you choose to share (only on first authorization), to create or link your account.

(2) WeChat Login (iOS / Android)

On Android we integrate the third-party SDK WeChat OpenSDK Android (com.tencent.mm.opensdk). SDK name: WeChat OpenSDK Android; developer: Shenzhen Tencent Computer Systems Company Limited. SDK privacy policy URL: https://support.weixin.qq.com/cgi-bin/mmsupportacctnodeweb-bin/pages/RYiYJkLOrQwu0nb8. When you choose WeChat login, we receive your openid, nickname, and avatar from WeChat to create or link your account. On Android, the SDK may access your app install list to determine whether WeChat is installed; without this permission you cannot use WeChat quick login. On iOS, the SDK collects device model information and stores it only on your device for cross-device compatibility, and uses the system clipboard to transfer information between this app and the WeChat app.

The above related information will not be provided to third parties in any form.

3. Account Deletion

If you have registered an account, you may request deletion in the mobile app: open the "My" / profile screen and use "Delete account". Please read the in-app warnings carefully. After deletion, you will no longer be able to use that account; cloud favorites and other personal data linked to the account will be deleted or anonymized according to our rules and cannot be recovered. Back up any important data before you proceed. We will process your request after verifying your identity, as described in the in-app flow.
