PRIVACY POLICY FOR LIVASUB

Effective Date: August 29, 2026
Last Updated: August 29, 2026

HaiVo (“we,” “our,” or “us”) provides the LivaSub – AI Live Translator mobile application (“LivaSub” or the “App”).

This Privacy Policy explains how LivaSub processes information, what limited technical data may be collected, and how user privacy is protected.

1. Overview

LivaSub provides live speech recognition, subtitles, language identification, translation, text-to-speech, offline language models, and local conversation history.

LivaSub is designed so that the content of your conversations is processed locally on your device.

LivaSub does not send your microphone audio, recognized speech, subtitles, transcripts, translation input, or translation output to any third-party AI service or external server for AI processing.

The App does not require a user account.

2. On-Device Speech Recognition and Translation

LivaSub's core processing pipeline operates locally on the user's device:

Microphone Audio → On-device Nemotron ASR ONNX → Recognized Text → On-device Google ML Kit Translation → Translation Result

Speech-to-text recognition is performed locally using a Nemotron ASR model running on-device through ONNX.

Translation and supported language identification are performed on-device using Google ML Kit.

LivaSub does not send users':

  • Microphone audio

  • Recognized speech

  • Subtitle content

  • Conversation transcripts

  • Translation input

  • Translation output

  • Text entered for translation

to HaiVo, NVIDIA, Google, or any other third-party AI provider for speech recognition, translation, AI model training, profiling, or advertising.

An Internet connection may be required to initially download or update speech-recognition or translation model files.

These model-download requests do not contain the user's microphone audio, conversation content, transcripts, or translated text.

After the required models are installed, supported speech-recognition and translation features can operate without an Internet connection.

3. Microphone and Audio Processing

When you start a live subtitle or translation session, LivaSub may request access to your device microphone or another supported audio source.

Audio is:

  • Processed temporarily on your device;

  • Used to generate speech recognition, subtitles, and translations;

  • Not intentionally stored as a permanent audio recording;

  • Not uploaded to our servers;

  • Not sent to third-party AI services;

  • Not used for advertising or profiling; and

  • Not used to train remote AI models.

Microphone access begins only after you grant the required operating-system permission and activate a feature that requires audio input.

On supported Android devices, LivaSub may also process eligible device audio after the user approves the operating system's audio or screen-capture permission.

LivaSub does not bypass operating-system or application audio restrictions.

4. Local Data and Conversation History

LivaSub may store certain information locally on your device, including:

  • Recognized subtitle text;

  • Translated text;

  • Conversation history;

  • Selected source and target languages;

  • Session date and time;

  • App preferences and settings; and

  • Downloaded model information.

This information remains on your device and is not remotely accessible by HaiVo.

You can remove locally stored information by deleting conversation history inside the App, clearing the App's storage, removing downloaded models, or uninstalling the App.

Device backup services may retain local App data depending on your operating-system and account settings.

5. Analytics and Diagnostic Information

LivaSub may use Google Analytics for Firebase to understand how the App is used and improve its functionality.

Limited analytics information may include:

  • App launches and sessions;

  • App version;

  • Operating-system version;

  • Device model;

  • Approximate geographic region;

  • Onboarding completion;

  • Feature usage;

  • Selected language codes;

  • Model download status;

  • Translation session duration;

  • App settings or mode changes;

  • In-app purchase events; and

  • Pseudonymous app or installation identifiers.

Analytics events are designed not to contain microphone audio, recognized words, subtitles, transcripts, translated text, text entered by the user, contacts, passwords, or precise GPS location.

LivaSub may also use Firebase Crashlytics to diagnose crashes and technical problems.

Crash reports may contain technical information such as:

  • Stack traces;

  • Error information;

  • App version;

  • Device model;

  • Operating-system version;

  • Crash time; and

  • Pseudonymous installation identifiers.

Crash reports are designed not to contain users' microphone audio, transcripts, subtitle content, or translation content.

6. Third-Party Services

LivaSub may use the following third-party technologies:

Google ML Kit

Used for on-device translation and language identification.

Translation input and output are processed locally on the device. Google services may be contacted to download language models and may process limited technical, diagnostic, SDK, or model-download information.

User conversation content is not sent to Google for translation processing.

Google Analytics for Firebase

Used for limited App usage and engagement analytics.

Firebase Crashlytics

Used to identify crashes and technical problems.

Apple App Store and Google Play

Used to distribute the App and process purchases.

Apple or Google may process payment and transaction information according to their own privacy policies. LivaSub does not receive or store full payment-card information.

We do not authorize these providers to use users' microphone audio, transcripts, subtitles, or translation content for their own AI processing, advertising, or model training.

Third-party service providers process limited information according to their applicable privacy terms and are expected to provide protections consistent with applicable privacy and data-protection requirements.

7. Permissions

Depending on your device and the features you use, LivaSub may request access to:

Microphone
Used for live speech recognition, subtitles, and translation.

Device Audio or Screen Capture
Used on supported devices to process eligible audio after operating-system approval.

Display Over Other Apps
Used on supported Android devices to display floating subtitles.

Internet Access
Used to download required models, communicate with supported platform services, send limited analytics data, and submit technical crash reports.

Bluetooth and Audio Routing
Used to manage compatible audio devices.

Notifications and Background Services
Used where required to maintain an active subtitle session or display its status.

You may revoke permissions through your device settings at any time. Some features may stop working if their required permissions are disabled.

8. Advertising and Tracking

The current version of LivaSub does not contain third-party advertising.

LivaSub does not sell or rent personal information.

We do not use microphone audio, conversations, subtitles, transcripts, translation content, or local history for advertising, behavioral profiling, or cross-app tracking.

Limited analytics information may be processed using pseudonymous identifiers according to the user's device privacy settings and the configuration of the relevant SDK.

9. Data Retention

Audio, subtitles, transcripts, translation content, and conversation history processed locally are not remotely retained by HaiVo.

Locally stored history, settings, and models remain on the user's device until they are deleted, the App's storage is cleared, or the App is uninstalled.

Analytics and crash-diagnostic information may be retained by Google according to the configured retention settings and Google's applicable privacy policies.

10. Data Security

LivaSub relies on operating-system security protections for information stored locally on the device.

Limited analytics and diagnostic information transmitted by third-party SDKs uses the security mechanisms provided by those services and the underlying network platform.

No electronic storage or transmission method can be guaranteed to be completely secure.

11. Children's Privacy

LivaSub is intended for users aged 13 and older and is not specifically directed to children under 13.

We do not knowingly request names, email addresses, phone numbers, contacts, or other account information from children.

Parents or legal guardians should supervise a minor's use of microphone, device-audio, and locally stored conversation features where appropriate.

12. Changes to This Privacy Policy

We may update this Privacy Policy when LivaSub's functionality, SDKs, legal requirements, or data practices change.

When changes are made, the Last Updated date at the top of this page will be revised.
