Privacy Policy

1.1 Information you actively provide

We may collect the following personal information in the scenarios described below in order to deliver our Services:

1.1.1 Account registration and sign-in

When you register or sign in via email or a third-party account (such as WeChat or GitHub) we may collect:

• Email address for account creation and verification;
• Username and avatar obtained through authorised third-party login;

1.2 Information obtained from third parties

Where permitted by law, we may obtain supplementary information from third parties (such as social networks or advertising partners) to offer better personalisation and analytics. We will ensure that these third parties have obtained your consent before sharing information.

1.4 Device identifiers and installed app information (Android App)

To deliver push notifications, enable third-party login and protect account security, the App may process the following information when implementing related features. We only process data within the scope necessary for those features and do not use it for advertising profiling unrelated to our services.

• You may disable notification permission in system settings to stop push-related processing; if you decline WeChat login, we will not query WeChat installation status for that purpose.
• See Chapter 10 for the full third-party SDK list.

1.3 How we use your personal information

• To create and maintain your account;
• To provide personalised content, recommendations and notifications;
• To ensure platform security, prevent fraud and troubleshoot issues;
• To comply with legal obligations or cooperate with competent authorities.

2.1 Sharing

We do not share your personal information with companies, organisations or individuals outside of Memene unless:

• We obtain your explicit consent;
• Sharing is necessary to provide core features (for example, service providers that support message delivery);
• Sharing is required by law or competent authorities.

2.2 Transfer

If Memene undergoes a merger, acquisition or restructuring, your personal information may be transferred to the new operator. We will require the new operator to continue to comply with this policy or obtain your consent again.

2.3 Public disclosure

We will not publicly disclose your personal information unless you explicitly agree or disclosure is required by law.

3.1 Storage location and period

Your personal information is generally stored within China. We retain it only for the period necessary to achieve the purposes described in this policy, unless laws require a longer retention period.

3.2 Security measures

We adopt industry-standard measures such as encryption, access control and security audits to protect your data. Although we work hard to safeguard your information, the internet is not absolutely secure, so please keep your account credentials safe and create strong passwords.

You have the following rights under applicable laws:

• Access and correction: you may view and edit your personal information in the account settings;
• Deletion: you may request deletion of your account and related data where permitted by law;
• Withdrawal of consent: you may adjust your notification preferences or unsubscribe from newsletters at any time.

If you wish to exercise these rights, please contact us at official@hkai.ai.

We use cookies and tracking technologies to improve your experience. You can adjust cookie settings in your browser, but disabling cookies may affect certain features.

Memene is intended for users aged 18 and above. If we learn that information from minors was collected without guardian consent, we will delete it promptly.

We may update this policy from time to time. If the changes are material we will notify you via website announcements, email or other reasonable means. Please review the latest version regularly.

If you have any questions or requests about this policy, please contact us at official@hkai.ai. We will respond within 30 days.

This policy applies to Memene and its related services. Third-party services accessed through the Platform are subject to their own privacy policies.

You may request to deactivate your account at any time by sending an email to official@hkai.ai. Please use your registered email address and specify "Account Deactivation Request" to facilitate identity verification. After confirming your identity and ensuring there are no outstanding matters, we will complete the account deactivation within 15 business days and delete or anonymize your personal information within 30 days.

• Your account information and identifiable personal data will be deleted or anonymized;
• Information related to others or public content may be retained in an anonymous form;
• Due to legal, financial, or security requirements, we may retain certain records for the minimum necessary period as required by law.

Deleted data may be retained in an isolated environment for up to 90 days due to system backups and will be automatically purged upon expiration. Once the account deactivation is completed, it cannot be restored.

To ensure the normal operation and service functionality of the Memene mobile application on iOS and Android platforms, this section provides supplementary information regarding third-party SDKs and system permissions used in the App version. If you only use the Web version, you may skip this section.

10.1 Scope of Application

This section applies to the Memene mobile application downloaded and installed through the App Store, Android app stores, or other official channels.

The application is jointly operated by Hangzhou Yuansun Technology Co., Ltd. and its affiliate Hong Kong Artificial Intelligence Association.

10.2 Third-Party SDK Information

To enable third-party login, push notifications, number authentication and other features, we have integrated the following third-party SDKs in the App.

Some SDKs may involve device MAC address, OAID and similar identifiers, as well as installed app information read for WeChat login and number authentication security checks. We only call relevant interfaces when necessary and strictly follow data minimization.

We do not collect personal information unrelated to our services through the above SDKs, nor do we use the collected information for unauthorized purposes.

For specific data processing methods of third-party SDKs, please refer to their respective privacy policies.

10.3 System Permissions

To ensure the core functionality of the application, we may request the following system permissions.

You can manually enable or disable these permissions in system settings, but disabling them may affect certain features.

We will not access sensitive permissions such as contacts, photo albums, camera, microphone, or location without authorization.

10.4 Data Security and Cross-Border Transfer

Data storage and processing for the App version are consistent with the Web version, all completed on servers within China.

We will not actively transfer personal information overseas unless required by laws and regulations or with your explicit authorization.

10.5 App Self-Start and Associated-Start Disclosure

To ensure that push notifications, subscription updates and other notification services are delivered in a timely manner, the App integrates Alibaba Cloud Mobile Push and OEM push SDKs (OPPO, Xiaomi, Huawei, Honor, vivo on Android) and Apple Push Notification service (iOS). When a new notification arrives, the operating system wakes the App's process through these push channels to deliver the message; when you tap a notification in the system notification tray, the operating system launches the App and navigates to the corresponding page. These behaviors constitute App self-start / associated-start. Details are as follows:

How to disable: You may turn off the push toggle at Profile → Push Management → APP Push, which will guide you to the system notification settings page to revoke this app's notification permission. You may also revoke the notification permission directly in system settings. Once disabled, the self-start / associated-start behaviors above will no longer occur.

Consent timing: We only use device identifiers for login registration, push binding and core services after you read and agree to the Terms of Service and this Privacy Policy; you may tap Disagree and exit the App.

10.6 Device Identifier Disclosure

To establish push notification channels, recognise the same device across multiple accounts (with sign-out unbinding), deduplicate push messages, enable one-tap login and security controls, the App may read and use the following device identifiers (see Section 1.4):

We do not actively collect IMEI, MEID, IMSI, SIM serial number or similar sensitive identifiers for advertising or unrelated purposes. On iOS we use a random UUID stored in Keychain, not linked to hardware identifiers.

10.7 Policy Updates and Applicable Versions

If we add new third-party SDKs, advertising services, or analytics tools to the App in the future, we will promptly update the relevant information in this privacy policy and seek your consent again during version updates.

This section takes effect from the Memene App May 2026 version.
