Terms of Use

Last updated: May 25, 2026.

These Terms of Use govern your use of the Tongo mobile app and related realtime translation services provided by SYSTEM ART DESIGN LLC.

1. Service

Tongo provides realtime voice translation, translated text, translated speech, quick phrases, conversation UI, demo access, and subscription-based premium access. Translation quality can vary depending on language, accent, background noise, network connection, provider availability, and other factors.

2. Subscriptions and Purchases

Tongo Premium subscriptions are purchased through Apple using the App Store. Apple handles payment processing, renewal, cancellation, refunds, and payment method management. Subscriptions renew automatically unless canceled at least 24 hours before the end of the current billing period. You can manage or cancel subscriptions in your Apple ID settings.

3. Demo Access

Tongo may offer limited demo access so users can try the app before subscribing. Demo access may be time-limited, device-limited, or otherwise restricted.

4. Acceptable Use

You agree not to misuse Tongo, interfere with the service, attempt unauthorized access, reverse engineer protected service components, use the app for unlawful activity, or transmit content that violates applicable law or the rights of others.

5. Translation Limitations

Tongo is a general communication tool and is not a certified interpreter, legal advisor, medical advisor, financial advisor, or emergency service. Do not rely on Tongo for critical, medical, legal, financial, safety, or emergency communications without independent verification.

6. Intellectual Property

Tongo, including its app design, software, branding, and service components, is owned by SYSTEM ART DESIGN LLC or its licensors and is protected by applicable intellectual property laws.

7. Availability

We may update, suspend, limit, or discontinue parts of the service at any time. We do not guarantee uninterrupted or error-free operation.

8. Apple Standard EULA

Unless a custom EULA is configured in App Store Connect, Apple's standard End User License Agreement applies to apps distributed through the App Store. You can review Apple's standard EULA at apple.com/legal/internet-services/itunes/dev/stdeula/.
