Terms of Use

Last updated: 11 July 2026

Welcome to Boba Bopomofo. By using the app you agree to these terms.

1. The service

Boba Bopomofo helps you learn Zhuyin (注音 / ㄅㄆㄇㄈ) and Taiwanese Mandarin pronunciation. Free content is available to everyone; some units require a Boba Pro subscription.

2. Subscriptions & billing

Boba Pro is offered as an auto-renewing subscription (monthly or yearly).
Payment is charged to your Apple App Store or Google Play account at confirmation of purchase.
The subscription automatically renews unless cancelled at least 24 hours before the end of the current period.
You can manage or cancel in your App Store / Google Play account settings.
Any free-trial period, if offered, converts to a paid subscription unless cancelled before it ends; unused trial time is forfeited on purchase.
Prices are shown in the app before purchase and may vary by region.

3. Acceptable use

Please don’t attempt to reverse-engineer, disrupt, or misuse the app or its servers, or use it in any unlawful way.

4. Educational content

Learning materials are provided for general educational purposes. While we work hard on accuracy, we don’t guarantee any specific learning outcome or that content is error-free.

5. Disclaimer & liability

The app is provided “as is”, without warranties of any kind. To the extent permitted by law, we are not liable for indirect or incidental damages arising from use of the app.

6. Changes

We may update these terms or the app’s features over time. Continued use after an update means you accept the revised terms.
