I. What information do we collect

Personal information is any information related to an identified or identifiable natural person recorded electronically or otherwise. Sensitive personal information is personal information that, if leaked or illegally used, is likely to infringe upon the personal dignity of a natural person or endanger the personal or property safety of that natural person, including information such as biometrics, religious beliefs, specific identities, medical health, financial accounts, and whereabouts.

When you use our products and/or services, we need to collect and use your personal information, including:

1. 1. When you register or log in to our products and services, you can create or log in to your account using your mobile phone number, email address, password, or verification code to meet the online real-name system and other regulatory requirements of relevant laws and regulations; you can also complete your personal information by completing relevant online identity information (such as avatar, nickname, and personal profile) according to your needs. If you only need to use functions such as browsing and searching, you do not need to register as our user and provide the above information. When you are not logged in, we may collect your unique device identifier (such as IMEI, IDFA, IDFV, Android ID) for statistical data purposes. When you register/log in, in order to protect the security of your account, we will use the human-machine verification function to collect your browser type and settings, device type and settings, operating system, mobile network information (including operator and mobile phone number), and application version number through the SDK.

2. 2. In order to realize the additional functions of the products/services we provide to you, you can choose to authorize us to collect and use this information. If you refuse to provide it, you will not be able to use the relevant additional functions or achieve the functional effects we intend to achieve, but it will not affect your normal use of the basic functions of our products or services. You understand and agree to this.

3. 3. You can use the “Share” button to share community content to third parties (third parties include but are not limited to: Facebook, Tweitter, Line accounts). We need to access the mobile application installation list of your device to determine whether you have installed a third-party client. We will obtain the avatar and nickname of the third-party account you use when logging in through a third-party authorization service and save this information to the server. This information will be used to manage your account. Unless you choose to do so or comply with relevant laws and regulations, we will not provide the above information to the outside world, nor will we use it for any purpose other than this function.

4. 4. When you create an account, provide feedback, contact us directly, or otherwise use the Platform, you may provide some or all of the following information:

4.1 Information You Provide

4.3 Cooperating third-party SDK service providers

When you use the functions provided by a third party in the LemonX APP, we may access the software development kit (SDK) provided by the third party to implement the relevant functions. At this time, the third-party SDK service provider may collect your relevant personal information. We will fulfill our prudent obligations and conduct strict security monitoring of the aforementioned third-party SDK to protect the security of personal information.

When you visit a page in an app, AppsFlyer SDK collects the following information to analyze user behavior and provide better product services to users:

• App activity information: number of clicks, in-app searches, installed apps, other user-generated content, other actions.

• App information and performance: diagnostics, other app performance data, and may receive data about app launch time or battery charge level for anti-cheating detection.

• Location information: approximate location. The received IP address will be associated with a certain region/city.

• Device information: device ID or other IDs (such as IMEI identifier, MAC address, and advertising identifier).

When you use the login/registration function to verify human-machine identification, Geetest SDK will passively collect the following information

• Device information: device system, device model, device brand, device screen size, IDFA, IMEI, AndroidID, IDFV and location information, etc.

• Device environment information: jailbreak logo, simulator logo, debugging logo, etc.

4.4 When you use the personal avatar editing function and post posts, comments, photos, etc. in the community, we need you to authorize the use of the device's camera permissions; if you use the “Select from Album” method, we need you to authorize the use of the device's album permissions. When you save pictures in the APP to the album when necessary, we need you to authorize the use of the device's album permissions. At the same time, we will collect information such as clicks, browsing, following, favorites, searches, comments, sharing, uploads, friend relationships, medal information, and notes generated during your access and use of community services. The above information you upload and generate will be stored in our servers because storage is necessary to achieve this function.

4.5 When you are authenticating as a corporate employee, we will collect your company name, official website, establishment time, registration area, company size, corporate email address, and mobile phone number to verify your corporate employee identity and confirm your exclusive entity qualifications.

4.6 When you use the collection function of LemonX to store various types of information, such information will be uploaded and stored in our server so that you can use such information when you log in to LemonX on other devices. This is necessary to realize the collection function. We will store your collection information in an encrypted manner, and you can delete your collection information at any time. Unless you choose to do so or comply with relevant laws and regulations, we will not provide the above information to the outside world or use it for other purposes other than this function.

Below we will explain in detail the operating mechanism of this personalized recommendation service and how you can control it.

(3) We will provide real-time feedback on the recommendation model based on your browsing behavior when using the product, and continuously adjust and optimize the recommendation results to better provide you with high-quality content.

Please be aware that our personalized recommendation algorithm does not identify the real identity of a specific natural person, but only provides more relevant and richer information based on user behavior and characteristics. We will inform you of the user information collected for personalized recommendations, user feedback, and methods of controlling information recommendations through this privacy policy, instant notifications (such as pop-ups, prompts, etc.).
