TransTalk Privacy Policy

1. Personal Information We Collect and How We Collect It

To provide you with stable and secure AI real-time call translation services, we only collect personal information necessary to deliver the service, following the "minimum necessity" principle. We do not collect information unrelated to the service. Details are as follows:

(1) Account Login Information

• Email Information: When you register and log into the App, we collect the email address and email verification code you provide to complete account registration, login verification, and password recovery, ensuring your account security. This is necessary information for using the App. If you do not provide it, you will not be able to complete registration and login, and will not be able to use any services of the App.
• Account Password: The App login password you set will be encrypted before storage (using Android Keystore encryption; plaintext storage is prohibited). It is used solely for subsequent login verification and will not be stored in plaintext or disclosed to third parties.

(2) Call and Translation Information

• Basic Call and Translation Information: When you use the App for voice calls and real-time translation services, we collect the account identifiers of both parties (linked to your email account), call duration, call time, call type, translation language type, and translation trigger records. This is used to ensure proper functioning of calls and translation, troubleshoot issues, optimize service quality, and ensure translation accuracy and call fluency.
• Call and Translation Content: We do not actively collect or store your call content. However, your translated call content will be continuously saved within the App for your later review and reference of cross-language communication, improving your user experience. Only when you actively enable the "Call Recording" feature will the relevant call audio be stored on your local device. Translation content will be retained in the App on a long-term basis (linked to your account). We implement security measures such as encrypted storage for translation content, strictly protecting your communication privacy. We will not upload call content or translation content to servers for third-party access or use.

(3) Device and Network Information

To ensure the App functions properly, optimize service experience, and prevent security risks, we automatically collect your device and network-related information. This does not require manual input from you and specifically includes: device model, operating system version, device unique identifier (used only for device identification and not linked to personally identifiable information), network type (Wi-Fi/mobile network), IP address, and network connection status. This information is used solely for technical service optimization and security protection and will not be used to identify you personally.

(4) Other Voluntarily Provided Information

When you proactively provide feedback or submit suggestions to us, you may voluntarily provide information such as your name and contact details so we can communicate with you promptly to address your concerns. This information is non-essential, and you may choose not to provide it without affecting your normal use of the App's core services.

(5) Permission Requests

To provide core services, the App needs to request the following device permissions from you. Permission requests are only triggered when you use the corresponding functions. You may choose to grant or deny them at your discretion. Denial will not affect the use of unrelated functions. Details are as follows:

• Microphone Permission: Used to capture your voice during voice calls and to capture speech content for real-time translation, enabling core voice call and translation functions. If denied, you will not be able to use voice calls and translation services, but you can still use non-core functions such as account login and viewing call records normally.
• Storage Permission: Used when you actively enable the call recording feature to store related audio content to your local device. If denied, you will not be able to use the recording feature, but this will not affect core services such as calls and translation.
• Network Permission: Used for account login, call connectivity, and real-time translation data transmission to ensure normal use of voice call and translation functions. If denied, you will not be able to use any core services of the App.
• Ad Tracking Permission (iOS ATT): On iOS devices, we will request tracking authorization through the App Tracking Transparency framework for personalized advertising on ad platforms. You can manage this authorization at any time in your device's Settings → Privacy & Security → Tracking. If you deny authorization, we will still display ads but their relevance may be reduced.

(6) Advertising-Related Information

To support the App's continued free services, we integrate third-party advertising platforms to display rewarded video ads. You can earn free call credit rewards after watching ads. Data collection related to advertising services includes:

• Device Advertising Identifier: The App collects your device's advertising identifier (IDFA on iOS and AAID on Android) for ad platforms to perform frequency capping, conversion attribution, and personalized ad delivery. This identifier is a resettable, non-permanent identifier not linked to your personally identifiable information. You can reset your advertising identifier or enable the Limit Ad Tracking feature at any time in your device's system settings.
• Ad Interaction Data: Ad platforms collect interaction data such as ad impressions, clicks, and watch duration for ad effectiveness measurement and anti-fraud verification. This does not include your call or translation content.
• Custom Rule Data: To ensure proper issuance of ad rewards, we transmit your anonymous user ID (not email, phone number, or other personally identifiable information) to the ad platform, used solely for server-side reward verification callbacks and will not be used for any other purpose.

2. How We Use Your Personal Information

We use your personal information strictly in accordance with this Privacy Policy, solely for the purposes of providing our services, and not beyond the agreed scope. Specific usage scenarios are as follows:

• Account Management: Use your email information and account password to complete registration, login, password recovery, and account security verification, preventing risks such as account theft and abnormal login, ensuring the security of your account.
• Core Service Provision: Use basic call and translation information to ensure smooth voice calls and accurate real-time translation, troubleshoot call and translation issues, and optimize service quality. Call translation content will be continuously saved within the App for your later reference and review.
• Service Optimization and Security Protection: Use device and network-related information to optimize App performance, adapt to different devices and network environments, improve call and translation stability; identify risks such as abnormal login and malicious attacks, ensuring the security of the App and your personal information.
• Advertising Services and User Incentives: Use device advertising identifiers and anonymous user IDs to display rewarded video ads through third-party advertising platforms. You can earn free call credits after watching ads.
• User Feedback Handling: If you voluntarily provide feedback-related information, we will use that information to communicate with you, address your suggestions and issue reports, and improve service quality.

We will not use your personal information for purposes unrelated to the App's services. Without your explicit consent, we will not expand the scope of personal information usage without authorization.

3. Storage of Personal Information

• Storage Location: The personal information we collect will be stored on servers compliant with the Google Play User Data Policy and on your local device. Servers are deployed in compliant data centers to ensure data storage security.
• Storage Period: We store your personal information only for the period necessary to fulfill the service purposes set out in this policy: Account information will be stored for the duration of your account. If you delete your account, we will promptly delete or anonymize the information after the deletion is completed. Basic call and translation information, and device and network-related information, will be retained for a reasonable period (not exceeding 6 months) after service ends for troubleshooting and service optimization, after which they will be automatically deleted or anonymized. Call translation content is linked to your account and will be retained in the App for the duration of your account; you may delete it at any time via the in-app functionality. Advertising-related data will be retained on the server for a reasonable period for reward verification and automatically deleted thereafter.
• Storage Security: We employ industry-standard security measures, including data encryption (sensitive data is stored in encrypted form), access control, security auditing, etc., to prevent your personal information from being leaked, tampered with, or misused.

4. Sharing, Transfer, and Disclosure of Personal Information

We strictly protect your personal information and will not share, transfer, or disclose your personal information to any third party without your explicit consent, except in the following legal or agreed circumstances:

• Necessary for Core Service Provision: Sharing necessary personal information with our affiliates or cooperative service providers (e.g., sharing temporary speech segments with compliant translation service providers to enable translation functionality — these segments are used only for translation and immediately deleted upon completion; sharing device advertising identifiers and anonymous user IDs with advertising service providers to enable ad functionality). We execute strict confidentiality agreements with all partners.
• Legal and Regulatory Requirements: Disclosing your personal information as required by laws, regulations, judicial authorities, or administrative authorities (e.g., cooperating with criminal investigations, prosecutions, trials, or related proceedings).
• Emergency Situations: To protect the lawful rights and interests, life, or property safety of you or other users, or to maintain the normal operation of the App's services, necessary personal information may be shared or disclosed in emergency situations in accordance with the law.
• Mergers and Acquisitions: In the event of a merger, acquisition, asset transfer, or similar transaction, your personal information may be transferred as part of the transaction. We will require the new information holder to continue to comply with this policy; otherwise, we will require them to seek your authorization and consent anew.

We will not sell or rent your personal information to any third party. We will not use your call content, translation content, or other core privacy data for other advertising, push notifications, or marketing purposes.

5. Your Personal Information Rights

In accordance with relevant laws and regulations and the Google Play User Data Policy, you are legally entitled to the following personal information rights. We will provide convenient channels for you to exercise these rights:

• Right of Access: You may view your user ID, call records, translation records, and other personal information within the App.

Call translation content can be independently deleted at any time via the corresponding in-app functionality, and deletion takes effect immediately.
• Right to Withdraw Consent: You may withdraw your authorization for permissions such as microphone and storage in your device settings. After withdrawal, we will no longer collect the relevant personal information. For ad tracking authorization, you may disable it in iOS: Settings → Privacy & Security → Tracking, or on Android: Settings → Privacy → Ads → enable "Limit Ad Tracking."
• Right to Know: You have the right to review this Privacy Policy at any time. If we revise this policy, we will notify you via in-app pop-ups, in-app notifications, or other means.

6. Protection of Minors

The App is designed for adults and is not intended for minors under the age of 14. If you are under 14, please read this Privacy Policy accompanied by a guardian and use the App only after obtaining guardian consent. We do not knowingly collect personal information from minors. If a guardian discovers that we have collected personal information of a minor without effective guardian consent, they may contact us via our support email address, and we will promptly delete the relevant information.

7. Changes to This Privacy Policy

We may revise this Privacy Policy from time to time. When significant changes are made to the terms of this policy, we will notify you of the revised Privacy Policy through in-app pop-ups, in-app notifications, or other means. Significant changes include but are not limited to: changes to the scope of information collection, changes to the purposes of information use, and the addition of new third-party information recipients.
