Privacy Policy

1. Information We Collect

We collect information only as necessary to provide the Service:

• Registration and account data: phone number, email, password (stored encrypted), display name, avatar, etc.;
• Third-party sign-in data: when you sign in with Google, we obtain and record your email address, basic profile, and avatar; when you sign in with WeChat, we obtain and record your WeChat nickname, unique identifier (OpenID/UnionID), and WeChat avatar;
• Business data: call recordings and transcripts, summaries, message logs, contacts and leads, knowledge-base content, and other data you upload or generate;
• Payment data: order and payment-status information (full card/account details are handled by third-party payment providers and not stored by us);
• Device and log data: IP address, device and browser type, activity logs, and access times, used for security and service optimization.

2. How We Use Information

• To provide, maintain, and improve the Service;
• For authentication, account management, and customer support;
• To enable core features such as call connection, real-time translation, AI reception, transcription, and summarization;
• For billing, settlement, and transaction management;
• To protect the security of the Service and accounts and to prevent fraud and abuse;
• With your consent or as permitted by law, to send you service notices or marketing (you may opt out at any time).

3. Third-Party Sign-In (Google / WeChat)

When you choose third-party sign-in, the relevant platform provides necessary account information after your authorization:

• Google: we record your email address to create/match your account, verify sign-in, and send necessary service notices;
• WeChat: we record your WeChat nickname and unique identifier and obtain your WeChat avatar as your account avatar. We use the WeChat avatar only if you have not already set one; an existing custom avatar will not be replaced.

We use this information only as necessary for sign-in and account functionality.

4. Cookies and Similar Technologies

We use cookies and local storage to maintain your session, remember preferences (such as language and theme), and secure the Service. You can manage or clear cookies in your browser, though some features may be affected.

5. Sharing and Disclosure

We do not sell your personal information. We share it only in the following cases and require recipients to apply appropriate safeguards:

• Service providers: with necessary third parties for communications, payments, AI model inference, and cloud storage, limited to what their service requires;
• Legal obligations: as required by law, regulation, or lawful requests from judicial or administrative authorities;
• With your consent: in other cases where you have given separate consent;
• Business changes: in a merger, acquisition, or asset transfer, we will require the successor to remain bound by this Policy.

6. Cross-Border Data Transfers

Our servers and providers may be located in different countries or regions. For cross-border use, some of your information may be transferred and processed outside your country/region.

For such transfers, we adopt measures required by applicable law (such as data-transfer agreements, security assessments, or obtaining your consent) to ensure adequate protection.

7. Storage and Security

We retain your personal information only for as long as necessary to fulfill the purposes described in this Policy, unless a longer period is required by law.

We apply reasonable technical and organizational measures—such as encrypted transmission, access control, least-privilege authorization, and security auditing—to protect against unauthorized access, disclosure, alteration, or loss.

In the event of a data-security incident, we will activate our response plan and notify you and the authorities as required by law.

8. Your Rights

Subject to applicable law, you have the right to:

• Access, copy, and inquire about your personal information;
• Correct or supplement inaccurate information;
• Delete your personal information or close your account;
• Withdraw consent you previously granted;
• Object to or request an explanation of automated decision-making.

You can exercise these rights in account settings or by contacting us using the details below; we will respond within the statutory period.

9. Children’s Privacy

The Service is intended for business users and is not directed to minors. If you are a minor, please read this Policy with, and use the Service only with the consent of, your guardian. If we learn that we have collected a minor’s personal information without guardian consent, we will delete it promptly.
