imimchat (hereinafter “imimchat,” “we,” or the “Service”) is a cross-platform application that provides instant messaging, groups, media sharing, and audio and video calling features. This Policy explains how we handle information when you use the imimchat website, web application, and mobile applications.
We do not sell your personal information or use chat content for targeted advertising. Please read and understand this Policy before using the Service.
1. Information We Process
- Account and profile information: The account identifier required for registration and profile information you provide, such as your nickname, avatar, and signature.
- Communications content: Text, images, videos, files, voice messages, location sharing, group, and contact information that you send or receive, so that we can provide message synchronization and storage features.
- Device and network information: IP address, login time, device/system identifiers, app version, network connection information, and security logs, used for login, maintaining sessions, troubleshooting, and security protection.
- Push notification information: When you enable message notifications, we process Apple Push Notification service (APNs) device tokens or Web Push subscription information to send notifications.
- Location and call information: We process relevant information only when you actively use location sharing or audio and video calling features and grant the required permissions.
- Crash and performance information: When the relevant configuration is enabled, we process necessary error, performance, and usage events to help us improve stability. Features that are not configured will not collect related data as a result.
2. How We Use Information
- To provide features such as account registration, login, message sending and synchronization, groups, media uploads, search, notifications, and audio and video calls;
- To verify identity, maintain sessions, detect abuse, and protect account and Service security;
- To handle support requests you submit, fix faults, and improve Service performance;
- To comply with applicable laws and regulations and judicial or regulatory requirements.
3. Message Encryption and Visibility
imimchat supports end-to-end encrypted private chats. When end-to-end encryption is enabled, messages are encrypted and decrypted on the devices of the two communicating parties, and the server should not be able to read message plaintext. However, metadata necessary to operate the Service, such as account profiles, group relationships, and message timestamps, may still be processed by the server. Please refer to the encryption status actually displayed in the app.
4. Information Sharing and Third-Party Services
We use service providers only to the extent necessary to provide the Service. For example, Apple APNs is used to send iOS notifications; cloud servers, databases, caches, and object storage configured by the app deployer are used to host Service data. We do not sell personal information.
If you visit third-party links or use third-party services, those third parties may process information in accordance with their own policies. Please read their privacy policies separately.
5. Storage, Security, and Retention
Information is stored on the servers where the Service is actually deployed and in related infrastructure. We take reasonable security measures, including HTTPS/TLS, access controls, encryption in transit, permission isolation, and log audits. Information is retained only for as long as needed to provide the Service, fulfill legal obligations, or handle disputes. After the necessary retention period, we will delete or anonymize it, unless otherwise required by law.
6. Your Rights
To the extent permitted by applicable law, you may request access to, correction, deletion, or export of your personal information. You may also withdraw consent that can be withdrawn, request account deletion, or inquire about how information is processed. Deleting certain information or disabling permissions may make the corresponding features unavailable.
To exercise the rights above, contact us at security@imim.chat and describe your request and the information needed to verify your account. We will handle it within a reasonable period.
7. Protection of Minors
This Service is not intended to be independently registered for and used by children or minors who do not have the relevant civil capacity. If a guardian discovers that a minor has used the Service or submitted information without appropriate consent, please contact us at the email address above.
8. Cross-Border Transfers
Because network and Service deployment locations may differ, information may be processed on servers outside your country or region. Where cross-border processing occurs, we will take appropriate protective measures in accordance with applicable law.
9. Policy Updates
We may update this Policy when Service features, data processing practices, or applicable laws change, and will display the new effective date on this page. We will notify you of material changes by appropriate means through the app or website.
