Privacy Policy
Last updated: August 2026
Overview
Dixo is an English pronunciation coach that scores how you say each sound and coaches the ones to fix. Everything runs on your device. This policy explains what the app accesses and how it is used.
Data Collection
Dixo does not collect, store, transmit, or share any personal data. Specifically:
- No analytics or tracking of any kind
- No advertising or ad-related data collection
- No accounts, sign-up, or login
- One network request, ever: on first launch the app downloads its speech model (~317 MB) from our server (dixo.greatdanecode.com). Nothing is sent up: it is a plain download, with no account, no identifier and no data of yours attached. Like any web server, ours records standard request information (IP address, time, file requested) for a short period to keep the service running; it is not used to identify or profile anyone. After that download the app works fully offline and makes no further requests
- No crash reports sent to external servers
Your Voice
When you practice, the microphone records short clips so the app can score your pronunciation. This audio is processed entirely on your device by the speech model the app downloaded on first launch and is never uploaded or saved off-device. Recordings exist only briefly in memory while you practice.
Your Progress Data
Your practice history (scores, streaks, weak sounds) and settings are stored locally on your device using standard system storage. You can export this data to a file you choose and import it back, from Profile then "Your data". Nothing is transmitted; the file goes only where you send it.
Permissions
| Permission | Purpose | Data sent off-device? |
|---|---|---|
| Microphone | Listen to your speech and score your pronunciation | No |
Read mode uses the system photo picker, which runs out-of-process and needs no photo-library permission. Permissions can be revoked any time in your device's Settings app.
Third-Party Services
Dixo integrates no third-party SDKs, analytics, advertising networks, or social platforms. It is built entirely with the platform's own native frameworks.
Children's Privacy
Because Dixo collects no personal data, it complies with COPPA and similar regulations. The app has no user accounts, social features, or in-app purchases.
