User Service Agreement

Product: XD AI Translator
Effective Date: November 5, 2026

Welcome to XD AI Translator. Please read this agreement carefully before using the app. By installing, launching, or using the app, you acknowledge that you have read and agree to all of its terms.

1. Service Description

XD AI Translator is an on-device speech translation tool providing speech recognition, machine translation, and text-to-speech. Except for downloading model resources, the core translation features do not rely on a network connection; all processing is performed on your device.

2. Auto-Renewable Subscriptions

A subscription unlocks voice conversation, simultaneous interpretation, and text translation features. Monthly and yearly subscription plans are available; prices are as shown on the purchase page.
Eligible new subscribers can receive a 3-day free trial. Each Apple Account is eligible for only one free trial within the same subscription group.
Unless you cancel at least 24 hours before the end of the free trial or current subscription period, you will be charged automatically for your selected plan at the end of the free trial, and your subscription will automatically renew and be charged at the end of each subsequent period.
You can manage or cancel your subscription in your App Store account settings. Deleting the app does not cancel the subscription.
After deleting or reinstalling the app, you can use "Restore Purchases" to restore an eligible existing subscription.

3. Acceptable Use

You must comply with applicable laws and regulations and must not use the app for any illegal activity.
Translations are generated automatically and are for reference only. They should not be the sole basis for legal, medical, financial, or other professional decisions.
You are responsible for judging the accuracy of translations and for how you use them.

4. Intellectual Property

The intellectual property rights in the app, including its software, interface design, and documentation, belong to the developer. The open-source components used by the app (sherpa-onnx, llama.cpp, Piper TTS) are governed by their respective open-source licenses. Rights in the content you translate with the app remain with you or the original rights holders.

5. Disclaimers and Limitation of Liability

The app is provided "as is". We make no express or implied warranty regarding the accuracy, completeness, or timeliness of translations.
We are not liable for feature unavailability or abnormalities caused by device performance, system environment, network conditions, or third-party components.
To the maximum extent permitted by law, we are not liable for any indirect or incidental damages arising from the use of, or inability to use, the app.

6. Changes and Termination

We may update this agreement from time to time; updated versions will be published on this page. If you do not agree to the updated agreement, you may stop using and uninstall the app. Continued use constitutes acceptance of the updated agreement. You may stop using the service at any time by uninstalling the app.

7. Governing Law and Dispute Resolution

This agreement is governed by the laws of the People's Republic of China. Disputes arising from this agreement shall first be resolved through friendly negotiation; failing that, either party may bring the dispute before a people's court with jurisdiction at the developer's place of business.
