Privacy Policy

1. Introduction

QQLink Plus ("we", "our", or "us") is operated by KeepBit Exchange Inc, which is also the App Store seller. We operate 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. If you sign in with Apple or Google, we receive the account identifier returned by that service.

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

Messages: Chat messages are protected with end-to-end encryption. We cannot read the content of your encrypted chat messages. Message metadata (sender, recipient, timestamp) may be processed transiently to deliver messages. This end-to-end protection applies to chat messages; it does not automatically apply to text you send to support channels, nor to the in-app assistant and translation features described below.

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.

Wallet Information: When you use the wallet feature, we collect and process your cryptocurrency wallet addresses, balances, and on-chain transaction history to display your balance and transaction records. For hosted wallets, we process your wallet balance, ledger, and transaction data on our servers. For non-custodial (Web3) wallets, your private keys are generated and stored locally on your device and are never transmitted to our servers.

Transfer and Red Packet Data: When you send or receive cryptocurrency transfers or red packets, we process the transaction amount, token type, recipient identifier, timestamp, and transaction status. These transactions are recorded on the respective blockchain and may be visible to third parties; we cannot erase on-chain records.

Exchange Rate Data: To display fiat currency equivalents for your crypto assets, we fetch real-time exchange rates from third-party market data providers. This request does not transmit your wallet data to those providers.

Identity Verification (KYC): Where identity verification is required for money services features, we collect the identity information you submit, such as your name, date of birth, nationality, images of your government-issued ID, and a liveness/selfie recording. Verification is performed by our identity verification service provider. This is distinct from system Face ID or Touch ID, which is handled by your device operating system and is never sent to us.

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, including through the in-app assistant
• To detect and prevent fraud, abuse, money laundering, or security incidents
• To comply with applicable legal obligations, including anti-money-laundering recordkeeping obligations
• To process cryptocurrency transfers and red packets initiated by you
• To display wallet balances, transaction history, and fiat value estimates
• To provide market data for informed financial decisions
• To verify your identity where required for money services features

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 (for example cloud hosting, push notification delivery, identity verification, and market data), bound by confidentiality obligations and required to protect your data at least to the level required by this Policy and Apple App Store Review Guidelines; we remain responsible for processing performed by service providers on our instructions
• When required by law, court order, or government request, including reporting obligations applicable to registered money services businesses
• To protect the rights, property, or safety of QQLink Plus, our users, or the public
• With your instruction or separate consent

5. Data Retention and Withdrawal

Retention periods depend on the category of data. Account information is retained while your account is active and then deleted or anonymized after account deletion. Encrypted message content is stored only as long as needed to deliver it to offline recipients, then deleted from our servers. Hosted wallet ledger records are retained as required by applicable money services recordkeeping laws; blockchain records are permanent and cannot be erased by us. Identity verification records are retained by our verification service provider for the legally required period. Diagnostic and crash data is retained in accordance with Apple App Store required-reason API policies; advertising attribution data is retained according to the attribution provider’s retention settings. You can withdraw system permissions at any time in iOS Settings (for example camera, microphone, contacts, and tracking); you may also request deletion as described in Section 6. Withdrawal of permissions stops future collection but does not delete data already lawfully recorded.

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
• Withdraw consent, for example by turning off tracking or a system permission in iOS Settings
• Data portability

To exercise these rights, contact us at [email protected]

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 a child has provided us with personal data, contact us and we will delete that data.

8. Security

We implement industry-standard security measures including end-to-end encryption for chats, 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, including by service providers described in Section 4. We ensure appropriate safeguards are in place for international data transfers in compliance with applicable data protection laws including GDPR.

10. Analytics and Advertising Attribution (Tracking)

Where you allow tracking, we use the advertising identifier (IDFA) to measure install attribution and campaign performance, and for in-app product recommendations. Tracking begins only after you allow it in the system prompt. You can change that decision at any time in iOS Settings → Privacy & Security → Tracking. If you do not allow tracking, we do not access the advertising identifier for those purposes.

11. AI and Automated Processing

Customer support conversations, the in-app assistant, and translation features process the text you submit in order to generate a reply or a translation. Because the service provider must read that text to process it, these features do not have the end-to-end protection described in Section 2 for chat messages. Text you submit to these features is not used by us for third-party advertising. We do not list third-party AI vendor names on this page unless they are confirmed in the production environment.
