H7 Chat Privacy and Service Agreement

1. Scope and Service Description

This Agreement applies to the H7 Chat mobile application, in-app web pages, account system, messaging services, file services, audio and video call services, content safety and reporting services, as well as server APIs and WebSocket real-time communication capabilities supporting H7 Chat.

The current main features of H7 Chat include account registration and login, verification-code login, profile maintenance, friend search and friend requests, contact management, one-to-one chats, group chats, private chats, message translation, text/image/video/voice message sending, message pinning/deletion, unread message reminders, audio and video calls, user reports, group reports, blocking, feedback, notification push, 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 any user who registers, logs in to, accesses, or uses H7 Chat.

2. 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 mobile phone number, verification code, username, nickname, avatar, password or encrypted password credential, login Token, user ID, registration time, login time, login status, device information, network information, and necessary security verification information.

The information above 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, regulatory, or platform review requirements.

2. Profile and Social Relationships

You may set or modify your avatar, gender, personal signature, region, remarks, and other profile information in H7 Chat. When you add friends, delete friends, set remarks, 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 profile, friend relationship, request record, group member relationship, group name, group announcement, group avatar, administrator status, and operation records.

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

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

When you use features such as one-to-one chats, group chats, private chats, message pinning, message deletion, clearing chat history, conversation tags, conversation pinning, chat translation, reporting, and feedback, we may process the message sender, recipient, group, message type, message content, message ID, sending time, read status, recall status, pinned status, translation status, unread count, conversation identifier, and related operation records.

Message content may include text, images, videos, voice messages, files, emojis, call status records, or other content that you actively send. We process this information to complete message delivery, display message history, provide unread reminders, sync messages, support content safety governance, handle complaints and reports, troubleshoot issues, and maintain service security.

The private chat feature is designed to provide a more privacy-protective conversation experience. Private messages may use a separate private chat channel, device keys, local encryption materials, burn-after-reading status, and necessary message receipts. To protect the private chat experience, the relevant conversation list may display only a private reminder, sender, or unread status, and will not display decrypted private message content. Please keep your device and account secure. Device loss, app uninstallation, clearing local data, or changing devices may affect your ability to view private messages.

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

When you take or select images or videos, record voice messages, send files, upload an avatar, 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 address, thumbnail, media duration, and related message records that you actively select, capture, record, or upload.

This information is used to send messages, display profile information, display chat history, download files, process feedback, perform content safety review, and maintain service stability. Please do not upload content that you are not authorized to use or that infringes the lawful rights and interests of others.

5. Audio/Video Calls and Real-Time Communication

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

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

6. Message Push, WebSocket, and Service Notifications

H7 Chat uses a WebSocket real-time connection to send and receive messages. To enable real-time communication, we will process connection status, heartbeat detection, reconnection records, message sync status, and necessary network information.

To send you new message alerts, friend requests, group chat notifications, system notifications, or security alerts, we may process device identifiers, push Tokens, notification status, unread counts, message summaries, and notification records. You may disable notification permissions in your system settings. After disabling notifications, you may not receive message reminders in time.

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

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

To maintain a safe and healthy communication environment, H7 Chat may conduct necessary content safety checks, sensitive-word filtering, or violation filtering on user-generated content. For content suspected of being illegal, infringing, harassing, sexually explicit or vulgar, violent or terrorist, hateful or discriminatory, fraudulent, spam advertising, or otherwise inappropriate, we may block sending, restrict display, preserve necessary evidence, process reports, restrict account functions, or take other reasonable measures.

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, additional description, relevant message or group chat information, and submission time. After you add a user to the blacklist, we will process the blacklist status and restrict that user from continuing to send messages to you.

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

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

To keep H7 Chat secure and stable, we may collect IP addresses, network type, device model, operating system version, app version, language settings, API access logs, crash logs, exception information, performance data, and security risk-control records for identity verification, anti-spam, attack prevention, fault diagnosis, compatibility improvement, and service quality optimization.

3. Device Permission Usage

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

4. Information Storage and Security Protection

1. Storage Location

To provide H7 Chat services to you, we may store and process your personal information on servers, cloud services, or service provider deployment environments outside the country or region where you are located. Regardless of where your information is stored or processed, we will take reasonable protection 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, unless otherwise required by laws and regulations or necessary for handling disputes, security incidents, user complaints, platform reviews, or regulatory requirements. Account information is generally retained while the account exists. Chat records, group chat records, uploaded files, report records, feedback records, and security logs will be retained according to service needs, user requests, compliance requirements, and security governance needs.

After you delete relevant content, cancel your account, or withdraw authorization, we will delete or anonymize the relevant personal information within a reasonable period, except for information that must be retained by law, has already been anonymized, remains temporarily in backup systems, or is necessary for security maintenance and dispute handling.

3. Security Measures

We will use access control, identity authentication, transmission encryption, permission hierarchy, log auditing, data backup, security monitoring, abnormal access identification, and minimum necessary authorization to protect your personal information. For features such as private chats, the app may use local keys, device keys, message encryption, burn-after-reading timers, and separate message channels to enhance privacy protection.

Please understand that the Internet environment is not absolutely secure. Please properly protect your account, password, verification codes, and device, and do not disclose or transfer them to others. If you discover account abnormalities, device loss, or risk of information leakage, please contact us promptly.

5. Sharing, Transfer, and Public Disclosure

1. Sharing

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

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

We will require partners to process information according to the principles of legality, legitimacy, necessity, and minimization, and to take reasonable security protection measures.

2. Transfer

We will not proactively transfer your personal information to any company, organization, or individual. If a merger, division, acquisition, asset transfer, bankruptcy liquidation, or similar event involves the transfer of personal information, we will require the new holder to continue to be bound by this Agreement, or obtain your authorization and consent again when necessary.

3. Public Disclosure

We will publicly disclose your personal information only with your explicit consent, or when required by laws, regulations, judicial authorities, or administrative authorities. For the handling results of illegal or non-compliant accounts, group chats, or content, we may display or notify such results within the necessary and minimum scope.

6. Third-Party SDKs and Services

To implement some H7 Chat features, we may integrate third-party SDKs or services. Third parties will process information according to their own privacy policies, and we recommend that you also read the relevant third-party policies. Capabilities that may be involved in the current project include:

We will update the third-party service list according to business changes. If a third-party service changes materially and may affect your rights and interests, we will notify you through in-app prompts, agreement updates, or other reasonable methods.

7. Your Rights

You have the rights to access, correct, copy, delete, withdraw consent, cancel your account, restrict or refuse certain processing, and request explanations regarding your personal information. You may submit requests through your H7 Chat profile, account and security settings, blacklist, message deletion, feedback entry, or the contact methods listed in this Agreement.

1. Access and Correction

You may view or modify your avatar, personal signature, region, password, language, translation settings, contacts, blacklist, and certain conversation settings in the app. If you cannot complete a change yourself, you may submit a request through feedback or the contact email.

2. Deletion and Withdrawal of Authorization

You may delete chat records, clear conversations, unblock users, disable notifications, disable automatic translation, or withdraw permissions such as camera, microphone, and photos in system settings. After you withdraw authorization, we will no longer process the corresponding information based on that authorization, but this will not affect information processing that was already carried out based on your prior authorization.

3. Account Cancellation

If you need to cancel your H7 Chat account, you may do so through the relevant in-app entry or contact us. After cancellation, we will stop providing services to you and delete or anonymize your personal information, except for information that must be retained under laws and regulations, or that is necessary to maintain security, handle disputes, fulfill regulatory requirements, or protect the lawful rights and interests of others. Account cancellation may prevent you from recovering chat records, friend relationships, group information, uploaded files, and private chat local keys. Please proceed with caution.

8. Service Usage Rules

You must ensure that the information you provide when registering for and using H7 Chat is true, accurate, lawful, and valid, and you must properly protect your account, password, verification codes, and device.

If such losses involve our fault, we will assume responsibility according to law.

For losses caused by users' own reasons, third-party services, network failures, device issues, force majeure, legal/regulatory requirements, or reasons beyond our control, we will assume corresponding responsibility only to the extent permitted by law.

9. Protection of Minors

H7 Chat is mainly intended for users with full capacity for civil conduct. If you are a minor under the age of 18, please read this Agreement and use our services under the accompaniment and guidance of your parents or other guardians and with their consent. Guardians should help minors use online communication tools properly and avoid addiction, privacy leakage, or exposure to harmful content.

If we discover that we have collected personal information from a minor without guardian consent, we will delete it as soon as possible or take other necessary protective measures. Guardians who discover such circumstances may contact us through the methods listed in this Agreement.

10. Agreement Updates

We may update this Agreement according to laws and regulations, regulatory requirements, platform review requirements, product features, third-party services, or operational circumstances. After an update, we will notify you through page updates, in-app prompts, pop-ups, announcements, or other reasonable methods. If an update involves your important rights and interests, we will notify you in a more prominent manner. Your continued use of H7 Chat means that you accept the updated Agreement.
