Privacy Policy

1. Introduction

QQLink Plus ("we", "our", or "us") operates the QQLink Plus mobile and desktop applications. This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our services.

2. Information We Collect

Account Information: When you register, we collect your phone number or email address and a display name to create your account.

Device Information: We may collect device type, operating system version, and a push notification token to deliver messages to your device.

Messages: Messages are protected with end-to-end encryption. We cannot read the content of your encrypted messages. Message metadata (sender, recipient, timestamp) may be processed transiently to deliver messages.

Usage Data: We may collect anonymized usage statistics (such as feature usage frequency) to improve the app. This data cannot be linked to your identity.

3. How We Use Your Information

• To provide, maintain, and improve the QQLink Plus messaging service
• To deliver push notifications for new messages
• To provide customer support and respond to inquiries
• To detect and prevent fraud, abuse, or security incidents
• To comply with applicable legal obligations

4. Information Sharing

We do not sell, rent, or trade your personal information to third parties. We may share information only in the following circumstances:

• With service providers who assist in operating our service (e.g., cloud hosting, push notification delivery), bound by confidentiality agreements
• When required by law, court order, or government request
• To protect the rights, property, or safety of QQLink Plus, our users, or the public

5. Data Retention

Account information is retained while your account is active. Encrypted messages are stored only as long as needed to deliver them to offline recipients, then deleted from our servers. You may delete your account at any time, which will permanently remove your account data.

6. Your Rights

Depending on your jurisdiction, you may have the right to:

• Access the personal data we hold about you
• Request correction of inaccurate data
• Request deletion of your account and associated data
• Object to or restrict certain processing activities

7. Children's Privacy

QQLink Plus is not intended for children under 16 years of age. We do not knowingly collect personal information from children under 16. If you believe we have collected information from a child under 16, please contact us immediately.

8. Security

We implement industry-standard security measures including end-to-end encryption, TLS for data in transit, and secure server infrastructure. However, no method of transmission over the Internet is 100% secure.

9. International Data Transfers

Your information may be processed in countries other than your own. We ensure appropriate safeguards are in place for international data transfers in compliance with applicable data protection laws including GDPR.
