1. Introduction

OmniTalk — Real-Time Voice Translator ("OmniTalk," "we," "our," or "us") is committed to protecting your privacy. This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our mobile application.

OmniTalk is designed to be private by default: it requires no account, and whenever a language pair is downloaded to your device, speech recognition and translation run entirely on-device — your conversations never leave your phone.

By using OmniTalk, you agree to the collection and use of information in accordance with this policy. If you do not agree with the terms of this Privacy Policy, please do not use the app.

2. Information We Process

Voice and Speech Data

On-device (BASIC mode with downloaded languages): Your speech is transcribed and translated using Apple's on-device models. Audio and text are processed locally and are not transmitted to us or anyone else.
Apple online recognition: For a small number of languages without on-device speech support, audio may be processed by Apple's speech recognition service under Apple's privacy terms.
Cloud translation: When a language pair is not downloaded and you are online, the transcribed text (not audio) is sent to our cloud translation provider over an encrypted connection to perform the translation.
PRO mode: In PRO mode, audio is streamed to a premium cloud speech recognition service over an encrypted connection to provide higher-accuracy transcription.

We do not store your audio, transcriptions, or translations on any server. Cloud providers process this data solely to provide the recognition or translation service.

Camera Data

The camera is used solely to recognize text in the world (signs, menus, labels). Text recognition happens on your device; camera images are never uploaded or stored by us.

Conversation History

Your conversation history is stored locally on your device only. It is never uploaded to us or to any third party, and deleting the app removes it entirely.

Purchase Information

PRO subscriptions are processed by Apple through the App Store. We receive only anonymous purchase status (whether a subscription is active) — never your name, payment details, or Apple ID.

Diagnostics

We may receive aggregated crash reports and diagnostic data through Apple's standard, opt-in mechanisms to help us identify and fix issues. This data does not identify you.

3. Device Permissions

Microphone: Required to hear speech so it can be translated in real time.
Speech Recognition: Required to transcribe what is said so it can be translated.
Camera: Required only for the camera translation feature.

Each permission is requested only when the corresponding feature is first used, and you can revoke any of them at any time in iOS Settings.

4. Third-Party Services

Depending on the features and mode you use, the following services may process data on our behalf:

Apple (Translation & Speech): On-device translation models and speech recognition, including download of language models. Apple Privacy Policy
Cloud translation provider: Text translation when a language pair is not downloaded and you are online.
Cloud speech recognition provider: Speech recognition used only in PRO mode.

5. Data Sharing

We do not sell your personal information.

We may share information only in the following circumstances:

Service Providers: With the third-party services listed above, solely to perform speech recognition or translation you requested.
Legal Requirements: If required by law or in response to valid requests by public authorities.
Aggregated Data: We may use aggregated, anonymized data that cannot be used to identify you to improve the app.

6. Data Storage and Security

Local Storage: Your settings, downloaded languages, and conversation history are stored locally on your device.
Encryption in Transit: Any data sent to cloud services (text for translation, audio in PRO mode) is transmitted using industry-standard encryption (HTTPS/TLS).
No Server-Side Retention: We operate no servers that store your conversations, audio, or translations.

7. Your Rights and Choices

Stay On-Device: Download your language pairs and use BASIC mode — no conversation data leaves your phone.
Delete App Data: Delete conversations in the History tab, or remove all data by uninstalling the app.
Revoke Permissions: Disable microphone, speech recognition, or camera access at any time in iOS Settings → OmniTalk.
Questions or Requests: Contact support for any privacy-related request.

8. Children's Privacy

OmniTalk is not intended for children under the age of 13. We do not knowingly collect personal information from children under 13. If you are a parent or guardian and believe your child has provided us with personal information, please contact support, and we will take steps to delete such information.

9. Changes to This Privacy Policy

We may update this Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy on this page and updating the "Last updated" date. You are advised to review this Privacy Policy periodically for any changes.

Your continued use of the app after any modifications to this Privacy Policy constitutes your acceptance of such changes.
