H. How may we protect your Personal Information

Protection for you as our user is essential to our business. Maintaining a secure network and server system is in the best interests of our users and our partners. We process and store Personally Information using industry standard physical, technical, and administrative safeguards to secure such personal information against foreseeable risks such as unauthorized use, access, disclosure, destruction, and modification. Such security safeguards include the use of encryption, password protection and user authenticated access rights. While we will use reasonable efforts to create a secure, safe, and reliable OSC, the confidentiality of any communication or material transmitted to or from this OSC over the internet cannot be guaranteed.

We have established a data security management system focusing on data and its lifecycle centric and improved the security of personal information in multiple dimensions from organizational construction, system design, personnel management, and product technology. We will organize security and privacy protection training sessions to strengthen employees' awareness of the importance of Personal Information protection. We will update and disclose assessment reports on security risks, personal information security impact and other relevant content from time to time, which you may obtain through announcements of the OSC.

Where our physical, technical, or management protection facilities are damaged, resulting in unauthorized access, public disclosure, tampering or destruction of information and damage to your legitimate rights and interests, we will promptly activate emergency plans and take reasonable remedies to minimize the impact on your Personal Information and other interests. In the case of Personal Information incident, we will, pursuant to applicable laws and regulations, inform you: the general information and possible impact of the incident, the measures we have taken or will take, suggestions for you to prevent and reduce risks on your own, and remedial measures for you, etc. We will inform you of the incident-related information by email, letter, telephone, push notification, etc. Where it is difficult to inform the subject of Personal Information individually, we will publish an announcement in a reasonable and effective way. Meanwhile, we will also report the handling of Personal Information security incidents as required by the regulatory authorities.

The security of your Personally Information is also, in part, your responsibility. When you register through this OSC, you should select passwords that are hard to guess and you must keep your passwords private and confidential. You should not share your password with anyone and should not store it in an unprotected format, such as taped to your computer or saved in your email. We do not accept liability for unintentional disclosure.

I. How we may store your Personal Information

The information you provide to us may be archived or stored periodically by us according to backup processes and will only be retained for as long as is required for the purposes for which it was collected, to provide our products and services to you, resolve disputes, establish legal defenses, conduct audits, pursue legitimate business purposes, enforce our agreements, and comply with applicable laws.

J. Access, correction, deletion, and removal of Personal Information

You may access, update, correct or remove the Personally Information you provided to us by sending an email to

You can ask us to provide you with information about and copies of your Personally Identifiable Information that we keep by sending an email to

If you have any requests concerning your personal information or have any questions or comments about privacy, please send an email to Please include your contact information, the name of this OSC or service at issue, and a detailed description of your request or privacy concern.

Please Note:

Although we make good faith efforts to provide users with access to their Personally Information, there may be circumstances in which we are unable to provide access or delete certain information, including but not limited to where the information: contains legally privileged information, must be maintained according to law, would compromise others' privacy or other legitimate rights, where the burden or expense of providing access would be disproportionate to the risks to the individual's privacy in the case in question, or where it is commercially proprietary. If we determine that access should be restricted in any particular instance, we will provide you with an explanation of why that determination has been made and a contact point for any further inquiries. To protect your privacy, we will take commercially reasonable steps to verify your identity before granting access to or making any changes to your Personal Information.

Non-identifiable information in our databases will not be deleted. Like all responsible OSC, we maintain backup files as a protection against natural disasters, equipment failures, or other disruptions. Backup files protect you and us because they lessen the risk of loss of valuable data. Removing a record from our principal files does not remove that record from any of the backup systems. It may take up to 6 months before all information in a backup record is completely erased through the normal recycling of backup files. In the meantime, as long as backup records exist, they receive the same privacy and security protections as our other records.

All requests received from you under this Policy will be processed in line with applicable local laws.

b) Do Not Track
