Privacy Policy

1.1 Registering a SellerSprite Account

When you register a SellerSprite account, we may collect your mobile phone number, email address, SMS verification code, or other information necessary to create your account, verify your identity, and protect your account security, depending on the registration method you choose.

After registration, you may log in to SellerSprite and use features such as the User Center to view or update your name, nickname, login password, and other account information.

1.2 Login Information, Passwords, and Authentication Data

To complete account login, identify your login status, protect account security, and synchronize account information between the SellerSprite website and browser extension, we may process the following authentication information:

1. Account identifiers, such as your mobile phone number, email address, username, or SellerSprite account ID;
2. Login passwords or SMS verification codes that you actively submit;
3. Your login status;
4. Login cookies, session identifiers, session tokens, or other authentication identifiers associated with SellerSprite domains;
5. Authorization codes, access tokens, third-party account identifiers, and basic account information authorized by you and returned by a third-party login provider.

We use this information only to register accounts, verify identities, complete account login, maintain login sessions, synchronize account information, process logout requests, and prevent account theft or other security risks.

1.2.1 SellerSprite Account Passwords and Verification Codes

When you log in using a SellerSprite account password or SMS verification code, the SellerSprite authentication system processes the account information, password, or verification code that you actively submit to verify your identity.

Your password or SMS verification code is used only for authentication purposes. The SellerSprite extension does not permanently store your login password or SMS verification code in plain text within the browser extension, and we do not sell, rent, or use such information for advertising.

Authentication information is transmitted through a secure connection to SellerSprite authentication servers for verification.

The SellerSprite extension does not access passwords stored in your browser's password manager, record your keystrokes, or collect passwords that you enter on unrelated websites.

1.2.2 Login Cookies, Session Identifiers, and Authentication Tokens

The SellerSprite extension may use the Chrome cookies permission to access login cookies, session identifiers, or authentication tokens associated with SellerSprite domains for the following purposes:

1. Determining whether you are logged in to your SellerSprite account;
2. Synchronizing login status between the SellerSprite website and browser extension;
3. Associating extension features with your authenticated SellerSprite account;
4. Maintaining your login session and protecting account security.

Login cookies, session identifiers, and authentication tokens are considered authentication information.

We process such information only to the extent necessary to provide the login and account synchronization functions described above. We do not use the cookies permission to access cookies from websites unrelated to SellerSprite, and we do not use authentication information for advertising, user profiling, or purposes unrelated to the extension's stated functionality.

1.2.3 Third-Party Login Through Google, Facebook, WeChat, or Other Providers

When you choose to log in to SellerSprite through Google, Facebook, WeChat, or another third-party account, the login process is generally handled directly by the relevant third-party authentication provider.

Any password that you enter on a third-party login page is processed directly by that third-party authentication provider. SellerSprite does not access, read, collect, or store your Google, Facebook, WeChat, or other third-party account password.

After you provide authorization, we may receive the following information from the third-party authentication provider:

1. An OAuth authorization code or access token;
2. A unique third-party account identifier;
3. Your email address, nickname, profile image, or other basic account information that you have authorized the third party to provide;
4. Information about the authorization scope, authorization status, and authorization validity period.

We use this information only to complete third-party identity verification, create or link a SellerSprite account, log you in to SellerSprite, and maintain your login status.

The exact information provided to us depends on the permissions and authorization scope that you approve on the third-party authorization page.

The third-party authentication provider's processing of your personal information is also governed by that provider's own privacy policy and terms of service. We recommend reviewing those terms before granting authorization.

1. Search and query requests;

1. Your contact information;

2. Feature states;
3. Temporary cached data;

Locally stored data is used only to provide extension functionality, maintain user preferences, and improve extension performance.

Some locally stored information may be deleted or become invalid when you log out, uninstall the extension, or clear your browser data.
