Privacy Policy

Effective November 4, 2026 · Bản tiếng Việt

If the Vietnamese and English versions differ, the Vietnamese version prevails.

This policy explains what personal data the JiSpeak app (“JiSpeak”, “we”) collects, why, who processes it, how long it is kept and what rights you have. It is written with reference to Vietnam’s Decree 13/2023/ND-CP on personal data protection.

In short: JiSpeak has no ads, does not sell data and uses no third-party tracking or analytics SDKs. Your voice during a practice session is sent to the Google Gemini API so the AI tutor can reply and so your report can be generated. You can delete your account and all of its data inside the app.

1. Data controller

JiSpeak is developed and published by the individual developer Duc Nguyen Tien (Vietnam) through a personal App Store developer account. He is the controller of your personal data. Contact: support@jispeak.com.
