Privacy Policy

This Privacy Policy applies to the Rang application (“Rang”, “we”, “us”) and its subsequent versions. In this policy, our products and services are collectively referred to as the “Service”. Please read it carefully to fully understand our data handling practices. By using the Service, you agree to the terms of this Privacy Policy; if you disagree, please stop using it.

I. Information Collection

(A) Basic Information Collection

When you download and open Rang for the first time, we may collect device information, such as the device model, operating system version, and device identification code. This information is used to adapt the application and optimize its performance, ensuring a stable and smooth service. This process is completely anonymous and will not be associated with your personal identity. If you enable the device location function and grant permission, we will collect your approximate geographical location information to precisely push local social activities and nearby trending topics, creating a more regionally characteristic social atmosphere for you.

(B) User Interaction Information Collection

During your use of the application, when you browse user profiles, send messages, join group chats, or participate in interactive features, we will record the details of these interactions, such as chat records, likes, and comments. This behavioral information is used to recommend like-minded friends to you and optimize the social matching algorithm, enhancing your interactive experience. If the content you send, such as text, images, or videos, involves a speech-to-text function, the relevant voice segments will be temporarily stored solely for the purpose of accurate text conversion and will be deleted immediately after the conversion is completed.

II. Information Use

(A) Provision of Personalized Services

With the help of the collected information, we conduct in-depth analyses of your social preferences and interest tags to accurately recommend interesting users, popular groups, and topic discussions to you, allowing you to meet like-minded people at any time. We can also customize an exclusive message stream, presenting content that suits your taste and reducing the interference of irrelevant information.

(B) Service Optimization and Upgrades

By leveraging vast amounts of interaction data, we analyze user behavior patterns to identify the root causes of issues such as application lags and slow loading. We then take targeted measures to fix bugs and iterate features. Through A/B testing and collecting user feedback, we continuously improve the interface design and operation process, aiming to create a social space that is extremely convenient and comfortable for you.

We monitor in real-time for security threats such as abnormal logins and malicious attacks. Device and behavior information helps us quickly identify risks, freeze suspicious accounts, and intercept illegal operations. We encrypt all data during transmission and storage to safeguard your information security, allowing you to chat without worry.

III. Information Sharing and Disclosure

(A) Sharing with Affiliated Parties

Within the group to which Rang belongs, certain functions and data may be shared and coordinated to build an integrated social ecosystem and provide a seamless user experience. For example, another event-organizing application under the same group can combine the interests of Rang users to accurately recommend offline gatherings. When sharing information, only necessary data is transferred, and strict privacy protection rules are followed to ensure that your information remains controllable.

(B) Third-Party Partners

To enable specific services, such as push notifications, cloud storage, and data analysis, we collaborate with professional third-party providers. Before partnering, we conduct strict reviews of their privacy compliance qualifications and sign confidentiality agreements. Data transfer is limited to the necessary scope and is fully encrypted to prevent information leakage. For instance, for a push notification service, only the device identification code is passed for precise delivery, without involving any private content.

We often aggregate and anonymize large amounts of user data before sharing it for market research and industry trend analysis. These anonymized data have no personal characteristics and cannot be traced back to specific users. The purpose is to drive innovation in the social field and uncover popular trends, which in turn feeds back into service optimization.

IV. User Information Management

(A) Information Viewing and Modification

You can log in to Rang at any time and access the settings section to conveniently view your personal information profile. You can independently adjust your avatar, nickname, and personal signature. You can also turn on or off permissions for functions such as location access, message push, and friend recommendations as needed, precisely controlling the scope of information collection.

(B) Information Deletion

If you decide to deactivate your account and leave Rang, you can submit a request with one click. Upon receiving your request, we will immediately initiate the deletion process, erasing all your data from our servers, including chat records, friend lists, and personal information. Information associated with third-party platforms will also be cleared according to their respective rules, ensuring no residual traces are left.

V. Security Measures

We have invested in cutting-edge technology and a professional team to comprehensively protect your information security. We employ SSL encryption protocols to ensure that data is not stolen or tampered with during transmission. Our servers are equipped with multiple firewalls and intrusion detection systems to resist external malicious attacks. We regularly back up data to prevent data loss caused by hardware failures or natural disasters. When our internal employees access user information, they strictly adhere to the principle of minimal authorization, and the entire process is audited with a trace, preventing any unauthorized operations.

VI. Data Storage and Transfer

Your data is stored on secure cloud servers located in top data centers around the world, following high-standard operation and maintenance specifications. Based on business expansion and service optimization needs, data may be transferred across borders. However, the entire process is encrypted, strictly adhering to privacy protection standards to ensure the safety of your data.

VII. Children's Privacy Protection

Rang is designed for users aged 18 and above, and we have no intention of collecting information from minors. If we discover that we have inadvertently collected information from a minor, we will immediately initiate the deletion process to protect the rights and interests of minors.

VIII. Notification of Privacy Policy Changes

We reserve the right to amend this Privacy Policy as appropriate. Before any changes take effect, we will post announcements and push notifications in prominent positions within the application, along with links to the new policy. Please check regularly. Your continued use of the Service after the policy change indicates your acceptance of the new policy. If you disagree, you may stop using the Service and contact us to handle any outstanding issues.
