This Agreement applies to the H7 Chat mobile application, in-app web pages, account system, messaging services, file services, audio/video call services, content safety and report handling services, as well as the server interfaces and WebSocket real-time communication capabilities associated with H7 Chat.

The current main features of H7 Chat include: account registration and login, verification code login, personal profile management, friend search and friend requests, contact management, one-on-one chat, group chat, private chat, message translation, text/image/video/voice message sending, message pinning/deletion/recall, unread message reminders, audio/video calls, user reporting, group reporting, blocking, feedback, multi-language switching, push notifications, version updates, and necessary security risk control.

In this Agreement, "H7 Chat" and "we" refer to the operator that provides the H7 Chat application and related services; "you" refers to the user who registers, logs in, accesses, or uses H7 Chat.

II. How We Collect and Use Information

1. Account Registration, Login, and Identity Verification

When you register or log in to H7 Chat, we may collect and process your phone number, verification code, username, nickname, avatar, password or encrypted password credentials, login token, user ID, registration time, login time, login status, device information, network information, and necessary security verification information.

The above information is used to create accounts, verify identity, maintain login status, protect account security, prevent abnormal registration or attacks, recover or change passwords, provide basic communication services, and comply with legal requirements or platform review obligations.

2. Personal Profile and Social Connections

You can set or modify your avatar, nickname, email, gender, bio, notes, and other profile information in H7 Chat. When you add friends, delete friends, set notes, view contacts, send friend requests, handle friend requests, join or leave group chats, set group member roles, or manage group chats, we will process the corresponding user profiles, friend relationships, request records, group member relationships, group names, group announcements, group avatars, administrator status, and operation records.

This information is used to display your social identity, maintain friend and group chat relationships, complete message routing, synchronize multi-device status, and ensure group chat management and account security.

3. Chat Messages, Group Chats, and User-Generated Content

When you use one-on-one chat, group chat, private chat, message pinning, message recall, message deletion, clear chat history, conversation tags, conversation pinning, chat translation, reporting, and feedback features, we may process the message sender, recipient, group, message type, message content, message ID, send time, read status, recall status, pin status, translation status, unread count, conversation identifier, and related operation records.

Message content may include text, images, videos, voice, files, emojis, call status records, or other content that you actively send. We process this information to complete message delivery, message history display, unread reminders, message synchronization, content safety management, complaint and report handling, troubleshooting, and service security.

4. Image, Video, Voice, File, and Avatar Upload

When you capture or select images or videos, record voice, send files, upload avatars, save images or videos from chats, or submit feedback attachments, we will process the file content, file name, file size, file type, upload time, download URL, thumbnail, media duration, and related message records that you actively select, capture, record, or upload.

This information is used to enable message sending, profile display, chat history display, file download, feedback processing, content safety review, and service stability maintenance. Please do not upload content that you do not have the right to use or that infringes upon the lawful rights of others.

5. Audio/Video Calls and Real-Time Communication

H7 Chat supports one-on-one voice calls, video calls, and group calls through Tencent Cloud TRTC real-time audio/video capabilities. When you use audio/video calls, we and the relevant service providers may process user ID, room or call identifier, call type, call status, call start and end time, network quality, device audio routing, camera and microphone status, and the audio, video, and connection data necessary to complete the call.

The above information is used to establish, maintain, and end audio/video calls, improve call quality, troubleshoot issues, and prevent abuse. H7 Chat will not use the camera or microphone for purposes unrelated to your active use of photo capture, voice recording, voice messages, or audio/video calls.

6. Message Push, WebSocket, and Service Notifications

H7 Chat uses WebSocket real-time connections to enable message sending and receiving. To enable real-time communication, we process connection status, heartbeat detection, reconnection records, message synchronization status, and necessary network information.

To send you new message reminders, friend requests, group chat notifications, system notifications, or security alerts, we may process device identifiers, push tokens, notification status, unread count, message summaries, and notification records. You can turn off notification permissions in your system settings; after turning them off, you may not receive message reminders in a timely manner.

7. Translation, Content Safety, Reporting, Blocking, and Community Governance

When you actively use message translation or enable auto-translation, we will process the text to be translated, source language, target language, translation result, translation status, and necessary request records to return translation results or improve the service experience.

To maintain a safe and healthy communication environment, H7 Chat may perform necessary content safety checks, sensitive word or violation filtering on user-generated content. For content suspected of being illegal, infringing, harassing, pornographic or vulgar, violent or terrorist, hateful or discriminatory, fraudulent, spam advertising, or otherwise inappropriate, we may take measures such as intercepting messages, restricting display, preserving necessary evidence, handling reports, restricting account features, or other reasonable actions.

When you report a user, group chat, or chat message, we will process the reporter, reported user, reported group chat, reported content type, reported object, report reason, supplementary description, related messages or group chat information, and submission time. After you add a user to the blacklist, we will process the blacklist status and restrict the other party from continuing to send you messages.

8. Feedback, Customer Service, Troubleshooting, and Service Optimization

When you submit feedback, complaints, problem descriptions, or contact us, we will process the feedback content, contact information, related screenshots or attachments, device model, system version, app version, error information, and handling records that you submit, in order to locate issues, respond to requests, and improve the product.

To ensure the safe and stable operation of H7 Chat, we may collect IP addresses, network types, device models, operating system versions, app versions, language settings, API access logs, crash logs, exception information, performance data, and security risk control records for identity verification, anti-spam, anti-attack, fault location, compatibility improvement, and service quality optimization.

III. Device Permission Usage

H7 Chat does not enable your device permissions by default. We only request necessary permissions from the system when you actively use relevant features. You can manage or revoke authorizations in your device system settings; after revocation, the relevant features may not function properly, but other features that do not depend on that permission will not be affected.

IV. Information Storage and Security

1. Storage Location

To provide you with H7 Chat services, we may store and process your personal information in servers, cloud services, or service provider deployment environments outside your country or region. Regardless of where your information is stored or processed, we will take reasonable protective measures in accordance with this Agreement and applicable data protection requirements.

2. Retention Period

We retain your personal information only for the shortest period necessary to achieve the purposes described in this Agreement, except where otherwise required by laws and regulations or necessary for handling disputes, security incidents, user complaints, platform reviews, or regulatory requirements. Account profile information is typically retained for the duration of the account; chat records, group chat records, uploaded files, report records, feedback records, and security logs are retained based on service needs, user requests, compliance requirements, and security management needs.

When you delete relevant content, deactivate your account, or revoke authorization, we will delete or anonymize the relevant personal information within a reasonable period, except for information that must be retained by law, has been anonymized, is temporarily retained by backup systems, or is necessary for maintaining security and handling disputes.

3. Security Measures

We take measures such as access control, identity authentication, transmission encryption, permission grading, log auditing, data backup, security monitoring, abnormal access detection, and least-privilege authorization to protect your personal information. For features such as private chat, the application may use local keys, device keys, message encryption, and dedicated message channels to enhance privacy protection.

Please understand that the internet environment is not absolutely secure. Please safeguard your account, password, verification code, and device, and do not disclose or transfer your account to others. If you discover account abnormalities, device loss, or information leakage risks, please contact us promptly.

V. Sharing, Transfer, and Public Disclosure

1. Sharing

We do not sell your personal information to unrelated third parties. We may share your personal information only in the following necessary circumstances:

• When we obtain your explicit consent or authorization;
• To implement core H7 Chat features, sharing necessary information with cloud service, file storage, message push, real-time audio/video, translation, content safety, operations, or customer service providers;
• To handle reports, complaints, disputes, infringement, or security incidents, providing information to relevant parties, regulatory agencies, judicial authorities, or platform reviewers within the necessary scope;
• When required by laws, regulations, or administrative or judicial authorities.

We require our partners to process information in accordance with the principles of legality, legitimacy, necessity, and minimization, and to take reasonable security protection measures.

2. Transfer

We do not actively transfer your personal information to any company, organization, or individual. In the event of a merger, division, acquisition, asset transfer, bankruptcy liquidation, or other circumstances involving the transfer of personal information, we will require the new holder to continue to be bound by this Agreement, or re-obtain your authorization and consent when necessary.

3. Public Disclosure

We only publicly disclose your personal information when we obtain your explicit consent, or when required by law, regulations, or compulsory orders from judicial or administrative authorities. For the results of actions taken against illegal accounts, group chats, or content, we may display or notify within the necessary and minimal scope.

VI. Third-Party SDKs and Services

To implement certain features of H7 Chat, we may integrate third-party SDKs or services. Third parties process information in accordance with their own privacy policies, and we recommend that you also read the relevant third-party policies. The capabilities that may be involved in the current project include:

We will update the third-party service list based on business changes. If a third-party service undergoes significant changes that may affect your rights, we will notify you through in-app prompts, agreement updates, or other reasonable means.

VII. Your Rights

You are entitled by law to access, correct, copy, delete, withdraw consent, deactivate your account, restrict or refuse certain processing, and request explanations. You can submit requests to us through H7 Chat's personal profile, account and security, blacklist, message deletion, feedback entry, or the contact methods listed in this Agreement.

1. Access and Correction

You can view or modify your avatar, nickname, email, gender, bio, password, language, translation settings, contacts, blacklist, and some conversation settings in the app. If you are unable to make changes yourself, you can submit a request through feedback or the contact email.

2. Deletion and Withdrawal of Authorization

You can delete chat records, clear conversations, unblock users, turn off notifications, disable auto-translation, or revoke camera, microphone, album, and other permissions in system settings. After revoking authorization, we will no longer process the corresponding information based on that authorization, but this does not affect information processing that has already been completed based on your previous authorization.

3. Account Deactivation

If you need to deactivate your H7 Chat account, you can do so through the relevant in-app entry or by contacting us. After deactivation, we will stop providing services to you and delete or anonymize your personal information, except for information that must be retained by law, for maintaining security, handling disputes, fulfilling regulatory requirements, or protecting the lawful rights of others. Account deactivation may result in the inability to recover chat records, friend relationships, group chat information, uploaded files, and private chat local keys. Please proceed with caution.
