3. Zettlab Account Management

3.1 Account Registration and Login

(1) To use Zettlab, you may choose to register a Zettlab account using your mobile phone number or another method recognized by Zettlab (the specific methods available may vary depending on your country or region).

(2) We provide a login feature using third-party platform authorization, provided that you hold a lawful third-party software or platform account and comply with the requirements of applicable laws and regulations.

(3) The account name and password you set are your credentials for logging in to and using Zettlab; please ensure that this information remains secure.

(4) You acknowledge that this account is a globally unified Zettlab account, and that this information is necessary for us to provide you with our global services.

3.2 Account Information and Security

(1) All information you register must be true, accurate, and complete; if it changes, you should update it promptly. If you provide false information, we have the right to restrict or terminate your use of the account.

(2) You should properly safeguard your account information to prevent unauthorized intrusion into or use of your account. If you discover any abnormality or security vulnerability, please notify us immediately and take appropriate protective measures.

3.3 Account Conduct

Without another person’s express written permission, you may not open a Zettlab account in another person’s name, nor impersonate or imitate another person’s name, title, trade name, trademark, avatar, or other identifying information as your account information. When using your account, you must not mislead the public into confusing the owner of the account, and in particular must not create confusion with institutions or individuals widely known to the public, nor harm the personality rights, property rights, or other lawful rights and interests of others in any form. We have the right to review the account information you submit; if the account information you submit does not comply with applicable laws, administrative regulations, government rules, or this Agreement, we have the right to take measures permitted by law and regulation, including issuing a warning, requiring correction within a specified period, resetting your account information, restricting account functions, suspending use, closing the account, or prohibiting re-registration.

3.4 Transfer and Sharing of Accounts

(1) A Zettlab account may only be used by the original registrant and may not be transferred, lent, or shared with others.

(2) If we discover, or have reasonable grounds to suspect, that an account is being used by someone other than the original registrant, we have the right to suspend or terminate the service.

3.5 Security and Confidentiality of Accounts and Passwords

You must make every effort to maintain the security and confidentiality of your Zettlab account and password. All actions carried out using your account and password are deemed to be your own actions, and you bear full legal responsibility for them, including without limitation any legal liability arising from content you upload, download, share, or publish on the Zettlab platform. If you believe that your account or password may have been used unlawfully, or there is any other circumstance relating to account security, you should notify us immediately. If you lose your account or forget your password, you may attempt recovery in accordance with the guidance and procedures we provide. You understand and accept that our account recovery process relies primarily on matching the account information you provide against our system records. We cannot guarantee that you will be able to successfully recover your account, nor can we verify that the person making the request is the true rightful holder of the account. You must therefore ensure that the information you provide when registering and using your account is accurate, complete, and up to date. You bear all losses or risks arising from inaccurate information or inadequate safeguarding of your account.

3.6 Use of Linked Version Services

Unless otherwise expressly stated, you understand that when you log in to and use any linked version or feature using your Zettlab account, you are simultaneously bound by this User Agreement, the user agreement applicable to the linked version, and other relevant legal documents. If you find any conflict or inconsistency between the user agreement of a linked version (or other legal document) and this User Agreement, the user agreement of the linked version (or other legal document) shall prevail.

3.7 Coordinated Management Measures

We may take coordinated management measures across Zettlab and its linked versions. For example, if a penalty is imposed on you in Zettlab for violating applicable laws or this Agreement, your use of linked versions and related services may also be affected by such penalty, and vice versa.

3.8 Account Deactivation

You may apply to deactivate your Zettlab account. You may apply to deactivate only your own account and must complete the relevant verification procedure to confirm account ownership. After deactivation, we will delete or anonymize the information in your account, except where laws, regulations, or other applicable rules provide otherwise for the retention period or method of handling such information. After deactivation, you will no longer be able to log in to Zettlab using that account, and you will not be able to retrieve any content or information associated with the account.
