Privacy Policy

1. Scope and controller

This Policy applies to the Tradova Translator mobile application operated by Dưa Hấu AI (DuaHauAI) through chotaikhoan.vn. It does not replace the privacy policies of the app store, the translation service, the speech services of your device or the advertising networks described below.

2. Information the app processes

Text you translate

• Online translation: the text you type, paste, speak or capture with the camera is sent over HTTPS to Google's translation service to return the translation. We do not store it on our servers.
• Offline translation and "Offline only" mode: text is translated on your device with downloaded language packages and does not leave the device.

Camera frames and photos

While the Camera tab is open, or when you pick a photo, images are processed on your device to recognise text. Images are never uploaded or saved by the app.

Voice

While the microphone button is active, your speech is handled by the speech-recognition service provided on your device (by the device maker, Google or Apple). Their privacy terms apply. Text-to-speech uses the voice engine installed on your device.

History, favourites and settings

Translations, favourites and app preferences are stored only on your device. When you update from an earlier version of the app, its existing on-device history is moved into the new history list on the same device.

Error reports (optional)

The first time you open the app, it asks whether it may send error reports. Only if you agree, technical information about crashes, freezes and errors is sent to Sentry (sentry.io), the error-monitoring service we use, so we can fix problems faster: the app version, device model, operating system version, a random installation identifier and the technical description of the error. Error reports never include the text you translate, your photos or your voice, and the app removes web addresses that could contain your text before sending. You can turn error reports off at any time in Settings → Send error reports. See the Sentry privacy policy.

Advertising and technical data

When ads are shown, the advertising network may process an advertising identifier, approximate location derived from the IP address, and device and app information (see section 4).

3. How we use information

Information is processed only to:

• translate the text, speech or image you choose;
• show your history and favourites and remember your settings;
• download and manage offline language packages you request;
• show and measure ads that fund the free app;
• find and fix crashes and errors, if you allowed error reports;
• keep the app working reliably and comply with law.

We do not sell personal information and we do not build user profiles.

4. Advertising

• Huawei AppGallery version: uses Petal Ads (Huawei Ads) and requests non-personalised ads only. See the Petal Ads privacy statement.
• Google Play and iOS versions: use Google AdMob. In the EEA, the UK and Switzerland the app asks for your consent before personalised ads are shown, and you can change your choice in Settings → Ad privacy options. On iOS the app asks for permission to track (App Tracking Transparency); if you decline, only non-tracking ads are shown. See how Google uses information from ads.

5. Permissions

• Camera — only to translate text in front of you. Optional; requested when you open the Camera tab.
• Microphone — only for voice input and conversation mode. Optional; requested when you tap the microphone.
• Internet and network state — online translation, downloading offline packages and ads.

The app does not request location, contacts, phone state, storage or account permissions.

6. When information is shared

Information is shared only:

• with the translation service to translate text you submit online;
• with your device's speech services when you use voice input or read-aloud;
• with the advertising network of your app store version, as described in section 4;
• with Sentry, only if you allowed error reports, as technical error information (section 2);
• when required by law or to protect users and the security of the service.

7. Storage and retention

We do not run servers that store your text, voice or images. Error reports, if you allowed them, are kept by Sentry for up to 90 days and then deleted. History, favourites, settings and offline language packages remain on your device until you delete them in the app or uninstall the app.

8. Security

All network traffic from the app uses encrypted HTTPS connections. The app has no login and stores no passwords. No system is perfectly secure; please contact us promptly if you notice a problem.

9. Your choices

• Use Offline only mode so text never leaves your device.
• Delete individual history items or clear all history in the History tab.
• Remove offline language packages in Settings → Offline language packages.
• Turn error reports on or off in Settings → Send error reports.
• Change ad consent in Settings → Ad privacy options (where available) or reset your advertising ID in your device settings.
• Deny or revoke the camera and microphone permissions at any time in your device settings.

10. Children's privacy

Tradova Translator is not directed to children under 13 and does not knowingly collect their personal information.

11. Changes and contact

We may update this Policy when features, store requirements or laws change. The latest version and its date will remain available at this URL.
