I. How We Collect and Use Personal Information

1. Users do not need to register for an account with this app; they can simply download and install it. If you subsequently need to use an account, this app will clearly indicate that the registration is linked to a mobile phone number/email address. Please register for a "Company" account using a mobile phone number or email address that is not already linked to a "Company" account, or a mobile phone number that has not been blocked by the service in accordance with this Agreement. The Service may change the account registration and binding methods based on user needs or product requirements without prior notice to users.

2. "Weebill" is an app product based on the "Company." Users must authorize the Company to use their personal information during registration in order to successfully register a "Company" account. Therefore, by completing registration, users consent to the Service's collection, disclosure, and use of their information.

User information may be used for the following purposes:

Account Creation: Account registration is not currently required for use of this app.

However, this notification cannot distinguish whether clipboard information is being collected, and false positives may occur. Therefore, if you encounter such a notification, please contact us so we can troubleshoot the issue.

II. How to better control the use of personal information

(1) We attach great importance to the security of your personal information and will strive to take reasonable security measures (including technical and management aspects) to protect your personal information and prevent the personal information you provide from being improperly used or accessed, disclosed, used, modified, damaged, lost or leaked without authorization.

We adopt a strict data use and access system to ensure that only authorized personnel can access your personal information, and conduct security audits of data and technology in a timely manner.

(4) Although we have taken the above reasonable and effective measures and have complied with the standards required by relevant laws and regulations, please understand that due to technical limitations and the possibility of various malicious means, in the Internet industry, even if we do our best to strengthen security measures, it is impossible to always guarantee 100% security of information. We will do our best to ensure the security of the personal information you provide to us. (5) You know and understand that the systems and communication networks you use to access our services may have problems due to factors beyond our control. Therefore, we strongly recommend that you take active measures to protect the security of your personal information, including but not limited to using complex passwords, changing passwords regularly, and not disclosing your account password and related personal information to others.

Once a user information security incident (leakage, loss) occurs, we will inform you promptly in accordance with the requirements of laws and regulations: the basic situation and possible impact of the security incident, the disposal measures we have taken or will take, suggestions for your independent prevention and risk reduction, and remedial measures for you. We will promptly inform you of the relevant circumstances of the incident through push notifications, emails, letters, text messages and related forms. When it is difficult to inform you one by one, we will take reasonable and effective measures to issue an announcement. At the same time, we will also report the handling of the user information security incident in accordance with the requirements of relevant regulatory authorities. (7) Once you leave the Company and related services and browse or use other websites, services and content resources, we will have no ability and direct obligation to protect any personal information you submit on software or websites outside of the Company and related services, regardless of whether you log in, browse or use the above software or websites based on links or guidance from the Company.

If you are a guardian of a minor, we remind you to properly fulfill your guardianship responsibilities and protect the security of the minor's personal information. If the minor you supervise uses our apps or products, you should provide proper guidance and supervision. If you are a minor, please carefully read this Privacy Policy with the assistance of your parents or guardians before using our devices or apps. Only use our services or provide us with information with the consent of your parents or guardians.

If it is necessary to collect children's personal information from you in specific services, we will obtain your authorization and consent in advance and inform you of the purpose and use of the collection. If you do not provide the above information, you will not be able to enjoy the relevant services we provide. As a guardian, you should properly perform your guardianship duties and protect the safety of children's personal information. If the child himself needs to register or use our products and/or services, you should provide correct guidance and supervision.
