Coolwai Voice Privacy Policy

深圳市酷外智联科技有限公司 (Shenzhen Coolwai Zhilian Technology Co., Ltd., referred to as "we", "us", or "our") attaches great importance to the protection of your personal information and will take appropriate security measures in accordance with applicable laws. This Policy applies to all functions and services provided by "Coolwai Voice" (the "App"), including Bluetooth device discovery and control, audio playback, text-to-speech (TTS), shout/voice recording, and audio file import.

1. Information We Collect

We only collect information that is necessary to provide the features of the App, and we do not collect any personal or private information unrelated to those features. You may choose not to provide certain information, but this may prevent you from using the corresponding features.

1.1 Information You Provide Voluntarily

• Account information: When you register or sign in, we obtain the information required by the sign-in method you choose, including: your phone number (via carrier-based one-tap sign-in or verification code), your Apple account nickname and unique identifier, your Google account nickname and avatar, your WeChat account, or a username and password set by yourself. Credentials are stored using irreversible encryption.
• Text for speech synthesis: When you use the TTS feature, the text you enter is transmitted to our server and processed by our speech synthesis provider to generate speech (see Sections 5 and 6). The text is used solely to provide the feature and for necessary anti-abuse traceability; we do not read or retain your text beyond that.
• Customer support and feedback: Contact details and descriptions you voluntarily provide when contacting our support team or submitting feedback.

1.2 Local Audio Files (Not Collected)

• Audio files you produce through import (e.g., MP3), recording, shouting or speech synthesis are stored only on your own device and are used for playback on your device and your paired Coolwai Bluetooth device.
• The App does not offer cloud upload or storage of personal audio. Your audio files are never transmitted to our servers.

1.3 Device and Bluetooth Information

• To discover, connect to and control your Coolwai Bluetooth device, we process the device's broadcast data, device name, model, firmware version, unique identifier (MAC address) and connection status. This information is necessary to pair and control the device within your authorization.
• We do not read or collect unrelated data from your Bluetooth device, such as contacts or call logs.

1.4 Permissions We Use

• Bluetooth: Used to scan for, connect to and operate Coolwai devices, including playback and control.
• Microphone: Used only when you proactively initiate shout, recording or voice input. We never record audio in the background, and recordings are stored only on your device.
• Location (older systems only): Some older operating systems require the location permission in order for Bluetooth scanning to discover nearby devices. We do not collect, store or use your geographic location; this permission only enables the system to complete Bluetooth device discovery. Newer systems use the system-level Bluetooth scanning capability and do not require the location permission.
• Local file access: When you choose to import a local audio file (e.g., MP3), we only access the file you selected for import and playback, and we never upload that file.

1.5 Usage and Log Information

• To keep the service running and diagnose issues, we process necessary device information (device model, operating system version, app version, network type) and functional usage logs (e.g., feature triggers and latency).
• When an error occurs, we collect error logs to locate and fix the problem.

2. How We Use Information

We use your information only for the following purposes:

1. To create and maintain your account, enable sign-in, authentication and account security;
2. To provide core features including Bluetooth discovery, connection and control;
3. To provide the text-to-speech (TTS) service by converting text you enter into speech audio;
4. To keep the records necessary for the TTS feature, in order to prevent abuse, troubleshoot and enable security traceability;
5. To provide customer support and handle your feedback and complaints;
6. To improve the product, fix faults, protect network security, and fulfill obligations under applicable laws.

We do not use your personal information for purposes unrelated to those described above. If another purpose is required, we will seek your separate consent.

3. Local Storage and Cache

To improve your experience, we cache necessary configuration on your device (e.g., device connection parameters, interface preferences, sign-in status). Your audio files are also kept on your device. Such data exists on your device only and can be removed at any time through App features or by clearing the app's data via your system settings. This product does not use cookies for cross-site tracking.

4. Sharing, Processing and Disclosure

We do not sell, rent or otherwise trade your personal information to any third party. We share or entrust your information only in the following circumstances:

1. With your separate consent: after obtaining your explicit authorization;
2. When necessary to provide a feature: sharing the minimum necessary information with the service providers supporting this App (see Section 5);
3. Legal requirements: disclosing personal information when required by law, litigation, or a mandatory order of a competent government authority;
4. Corporate transactions: in the event of merger, acquisition or bankruptcy, the successor will be required to remain bound by this Policy or to obtain your authorization afresh.

5. Third-Party Services and SDKs

Some features of the App are supported by third-party providers. To enable these features, the minimum necessary portion of your information is transferred to the corresponding provider and is subject to that provider's privacy policy:

• Speech synthesis (Volcano Engine): When you use the TTS feature, the text you enter is transmitted to Volcano Engine (Beijing Volcano Engine Technology Co., Ltd., openspeech.bytedance.com) to generate speech. Necessary synthesis records may be kept on our server for anti-abuse and traceability purposes (see Sections 6 and 7). See Volcano Engine's privacy policy for details.
• Cloud services (uniCloud / Alibaba Cloud): We use DCloud's uniCloud service hosted on cloud servers located in mainland China (Alibaba Cloud). Our servers store only the necessary account information and necessary TTS records, and do not store your personal audio files.
• Identity providers: Sign in with Apple, Google Sign-In, WeChat sign-in and carrier-based one-tap sign-in are provided by Apple Inc., Google LLC, Tencent and the corresponding telecom carriers respectively for identity verification.
• Analytics (DCloud uni-analytics, when enabled): Used to understand feature usage and crash analysis; statistics do not contain information that identifies you personally.
• Advertising (mainland China channel versions only): Versions distributed through mainland China channels may integrate third-party advertising SDKs (e.g., Pangle), which process advertising identifiers under their own privacy policies. Versions distributed through app stores do not include advertising SDKs.

6. Storage and Security

6.1 What We Keep on Our Servers and for How Long

• We keep only two categories of data on our servers: (1) necessary account information (account identifier, sign-in method, registration time, etc.), retained while your account exists and deleted or anonymized upon deactivation; and (2) necessary TTS records (synthesis time, text used, account identifier, etc.), retained only for the period necessary to prevent abuse and enable security traceability (generally no more than 6 months), after which they are deleted or anonymized.
• The above data is stored on servers located in mainland China. Your audio files, contacts, photos and other personal data are not uploaded to our servers.

6.2 Security Measures

We protect your information with industry-standard technical and organizational measures, including encrypted transmission (HTTPS/TLS), access control, least-privilege principles and log auditing, and we assess security risks regularly. No method of transmission over the Internet is absolutely secure. Please safeguard your account credentials and enable your system's security features.

7. Your Rights

Subject to applicable law, you have the following rights regarding your personal information. You may exercise them directly through features in the App, or by contacting us through the channels in Section 10:

• Access and portability: request access to or a copy of your personal information;
• Rectification: correct inaccurate or incomplete personal information;
• Deletion: request deletion of personal information kept on our servers, including TTS records, where legally permitted; audio files on your own device can be deleted at any time through App features or your system's file manager;
• Withdraw consent: withdraw authorization for a permission (e.g., microphone, Bluetooth) or a processing activity; withdrawal does not affect the lawfulness of processing that occurred before withdrawal;
• Account deactivation: deactivate your account via "Me – Account Management – Deactivate Account". Upon deactivation, we delete or anonymize the account information and personal data stored on our servers, except where retention is required by law. Deactivation is irreversible — please proceed with caution;
• Complaints: file a complaint about our processing with us or with a supervisory authority.

We will respond to your request within 15 business days. For security reasons, we may need to verify your identity before handling certain requests.

8. Children's Privacy

This product is intended for adults and is not directed to children under the age of 14. If you are a minor, please use the App only after a parent or guardian has read and agreed to this Policy and the Terms of Service. If we become aware that we have collected personal information of a child without verifiable parental consent, we will take steps to remove that information promptly. Parents or guardians may contact us to request access to or deletion of a child's personal information.

9. Policy Updates

We may update this Policy from time to time. For material changes (e.g., changes to the categories of information collected, purposes of use, or sharing partners), we will notify you through prominent in-app means (pop-ups, announcements or in-app messages) and update the version and date on this page. Your continued use of the product after the changes take effect constitutes acceptance of the revised Policy.
