Golden Mango Privacy Policy

Introduction

Welcome to Golden Mango (「金芒果」)!

Golden Mango ("we," "our," or "the App") is operated by Shanghai Golden Mango Technology Co., Ltd. (Registered address: No. 1999 North Xing Highway, Sanxing Town, Chongming District, Shanghai, China (centralized registration address); Contact: mongram.app@gmail.com). We understand the importance of your personal information and are committed to protecting it securely and responsibly. We follow the principles of lawfulness, fairness, necessity, and good faith.

Please read this Privacy Policy carefully before using our products. Important points are shown in bold. This policy applies to the Golden Mango mobile apps (Android / iOS) and related services, including app store listings and user consent requirements.

1. Information We Collect and How We Use It

We collect and use personal information that you provide, authorize, or generate while using our services, only for the purposes described in this policy. If you refuse information or permissions required for a specific feature, that feature may not work, but other features may still be available.

1.1 Service Operation and Account Security

To keep the service running, troubleshoot issues, and protect accounts, we may collect: device information (model, OS version, device identifiers such as Android ID / OAID / IDFV where permitted by law and necessary for push delivery or security), network information (IP address, network type), app information (version, logs, crash and performance diagnostics), and push tokens (FCM / APNs / vendor push tokens). We do not collect device serial numbers, IMEI, IMSI, or MAC addresses. Device-related collection by the app or SDKs occurs only after you agree to this policy.

1.2 Registration, Login, and Account Management

1. Phone / email / username login: You may register with a phone number, email, or username. We may collect your phone number, email address, and account ID, and verify identity via SMS/email codes or password. Phone numbers are sensitive personal information collected for account security and applicable legal requirements.
2. Third-party login: With your authorization, you may sign in with a Google account or Apple ID. We receive only the identifiers returned by the provider (e.g., OpenID, email) within the scope you authorize, to create or link your Golden Mango account.
3. Invite codes / deep links: If you join via an invite link or code, we may collect invite codes and attribution data to bind referral relationships.
4. Account deletion: You may delete your account in the app via Me → Account Setup → Delete Account. After deletion, we will delete or anonymize your personal information as required by law, except where retention is legally required.

1.3 Messaging and Content Interaction

1. Messages and content: When you send text, images, voice, video, files, location, or contact cards, we process the message content, media files, and location data (latitude/longitude) you submit for transmission, storage (as designed), display, and sync across devices. Location sharing in chat requires your location permission.
2. Photos / camera / microphone / files: To send or save media, take photos, scan codes, or attach files, we request storage/album, camera, microphone, and file access permissions. On Android 13+, media permissions may be requested separately for images and video.
3. Profile: You may set avatar, nickname, gender, region, etc. Setting an avatar may use the camera or photo library.
4. QR codes: Scanning or displaying QR codes to add friends or join groups requires camera permission.
5. System sharing: Content you share to or from other apps is processed as you choose to share it.
6. Reporting and community rules: You may report illegal or abusive content or block users in the app. See our Community Guidelines. To handle reports, we may retain the reason, description, and related conversation identifiers you submit.

1.4 Voice/Video Calls and Online Meetings

Calls and meetings require microphone and camera permissions and may use Bluetooth for headsets. For incoming call alerts and background operation, we may use notifications, overlay/full-screen incoming call UI, wake lock, foreground services, and battery optimization exemptions where applicable.

1. Real-time audio/video: Live streams are captured and transmitted during calls/meetings via our real-time communication services.
2. Screen sharing: Screen sharing requires screen capture / media projection permission and may capture information visible on your screen.
3. Meeting recording: When recording is enabled, meeting audio/video and metadata may be stored for playback, minutes, or compliance. Continuing a recorded meeting indicates you acknowledge the recording (see in-app notices).
4. Live captions and translation: Captions may use the microphone and (on iOS) speech recognition to convert speech to text; translation processes caption text via on-device or server-side processing.
5. Meeting background music: Extended features may process audio you select; local library access follows system permission prompts.

1.5 In-App Security Lock

If you enable biometric or gesture unlock, verification uses Face ID / fingerprint / device biometrics or a gesture password on your device. Biometric templates are handled by the system secure enclave; we do not upload biometric templates.

1.6 Customer Support

When you contact us, we may retain your communication records, issue descriptions, and contact details to resolve your request.

3. Storage and Security

Personal information collected and generated in our operations within the People's Republic of China is generally stored in China. We use TLS/HTTPS encryption in transit, access controls, and security audits. No internet transmission or storage is 100% secure—please protect your account credentials.

For overseas users: If you use a version provided for overseas regions, your information may be processed or stored outside mainland China (e.g., Hong Kong SAR) for regional access and service quality. We apply appropriate safeguards as required by law. Messages are stored on our servers to enable multi-device sync and are not end-to-end encrypted in the Signal/WhatsApp sense.

4. Your Rights

You may access, correct, delete personal information, withdraw consent, delete your account, and disable permissions in device settings. Contact us at mongram.app@gmail.com or use in-app settings. We will respond within the legally required period (typically within 15 business days) after verifying your identity.
