Privacy Policy — Big-O Personal Data Protection Statement

Regarding the protection of personal data, please read the following Big-O Privacy Policy carefully. Big-O is a brand operated by Big-O Information Intelligence Corp. (大鷗摩飛智能有限公司). In order to protect personal privacy and support personal data protection, Big-O hereby makes the following declaration to inform you of the purposes, categories, scope of use and methods of Big-O's collection of personal data, as well as the rights you may exercise. If you have any questions regarding Big-O's Privacy Policy, the related notices below, or any matters related to personal data protection, please contact the Big-O Customer Service Center, and Big-O will respond as soon as possible.

Scope of Application

This Big-O Privacy Policy and the notices contained herein apply only to websites owned and operated by Big-O. Big-O websites may contain links to, or goods or services provided by, other partners and individual store operators. For the privacy policies and personal data protection notices of such linked websites, partner websites, or individual online stores, please refer to the respective websites.

Purposes and Categories of Personal Data Collection

For the purposes of providing e-commerce services, after-sales services, fulfilling statutory or contractual obligations, protecting the rights and interests of data subjects and relevant stakeholders, marketing, customer management and service, and conducting business in accordance with registered business items or organizational charters, Big-O may, depending on the nature of each service, collect your name, contact information (including but not limited to phone numbers, email addresses, and physical addresses), information required to complete collection or payment, IP addresses, and other personal data that can directly or indirectly identify you. In addition, to improve service quality, Big-O may, depending on the nature of the services provided, record users' IP addresses and browsing activities on Big-O's related websites or apps (e.g., the hardware and software used, web pages clicked, apps downloaded). However, such data is used solely for traffic analysis and online behavior research to improve the service quality of Big-O's related websites and will not be associated with any specific individual.

Use of Personal Data

Personal data collected by Big-O that is sufficient to identify a user will only be processed and used internally by Big-O in accordance with the purposes of collection. Unless prior notice has been given, or it is necessary for providing services or fulfilling contractual obligations, or as required by applicable laws and regulations or by orders of competent authorities, Big-O will not provide personal data sufficient to identify a user to any third party (whether domestic or foreign) or use such data for purposes other than those for which it was collected. Big-O will continue to maintain, process, and use such data during the retention period prescribed by law.

Data Security

Big-O shall maintain the security of personal data using reasonable technical measures and procedures that meet industry standards.

Rights of Data Subjects

Data subjects may request to inquire about, review, or obtain copies of their personal data. If your personal data has changed or you discover that your personal data is inaccurate, you may request Big-O to amend or correct it. When the purpose for collecting personal data no longer exists or the retention period has expired, you may request the deletion, cessation of processing, or cessation of use of your personal data. However, this does not apply where such data is necessary for Big-O to perform its duties or conduct its business.

Cookies

For the convenience of users, Big-O websites may read cookie data stored on users' computers. Users may disable or restrict this functionality through their browser settings; however, doing so may prevent the use of certain website features. If you would like to know how to disable or restrict this functionality, please contact the Big-O Customer Service Center.

Google API Services and Google Calendar Data

Big-O uses Google Calendar API solely to provide user-requested appointment scheduling, calendar synchronization, and scheduling conflict prevention features.

When a user voluntarily connects their Google Account to our services through Google OAuth, we access Google Calendar data only to the extent necessary to provide these features. Depending on the functionality selected by the user, this may include creating, synchronizing, updating, or deleting calendar events associated with appointments and accessing calendar availability information necessary to prevent scheduling conflicts.

Google user data obtained through Google APIs is not sold or used for advertising purposes.

Google Workspace API user data is not transferred to or processed by third-party AI/ML service providers, including providers used by other AI-related features of the Big-O platform. Our AI-related functionality operates separately from the Google Calendar integration and does not access or process Google Workspace API user data.

We do not use Google Workspace API user data to train, fine-tune, develop, or improve generalized or foundation AI/ML models.

Google user data may only be processed by infrastructure or service providers acting on our behalf where necessary to operate, secure, and maintain the service, subject to appropriate confidentiality and data protection obligations.

Users may disconnect their Google Account from our service. When access is no longer required, applicable OAuth credentials and Google user data will be handled or deleted in accordance with our data retention practices and applicable legal requirements.

Big-O's use and transfer to any other app of information received from Google APIs will adhere to the Google API Services User Data Policy, including the Limited Use requirements.

Impact

If you are unwilling to provide the relevant personal data required for services or transactions to Big-O, and to consent to Big-O's collection, processing, use, and international transfer of such personal data in accordance with applicable laws and regulations and this Privacy Policy and related notices, Big-O will respect your decision. However, depending on the nature or conditions of the relevant services, you may be unable to use such services or complete related transactions, and Big-O reserves the right to decide whether to provide such services or complete such transactions.

Right to Amend

Big-O reserves the right to amend this Privacy Policy and related notices at any time. Any amendments will be published on the Big-O website without individual notice. You may review the amended Privacy Policy and related notices on the Big-O website at any time.
