Subtitle Studio App — Sync, Style, Export
Welcome to Fexo Subtitle Studio — your powerful lyric subtitle companion. At Fexo FZC LLC, we believe privacy is a fundamental right. This Privacy Policy explains how we handle information when you use our mobile application ("the App"), which allows you to add lyric subtitles to your videos, sync captions, style text, and export your creations.
By using Fexo Subtitle Studio, you agree to the practices described in this policy. If you do not agree, please discontinue use of the App.
We are committed to minimal data collection. Fexo Subtitle Studio does not require accounts, and we never collect personally identifiable information unless strictly necessary for functionality.
| Data Type | Description | Purpose |
|---|---|---|
| Device Info | Model, OS version, app version | Optimize performance and compatibility |
| Crash Reports | Anonymous stack traces & diagnostics | Fix bugs and improve stability |
| Usage Analytics | Feature interactions (import/edit/export) | Understand usage patterns to enhance UX |
We do NOT: Sell personal information, upload your videos, access your media for any purpose other than subtitle editing at your request, track your location, or use data for advertising profiling.
Local-First Approach: All videos you import, subtitle projects, editing history, and app preferences are stored exclusively on your device. We maintain no remote database containing your created content.
Security Practices: We follow industry best practices: encrypted data transmission (where applicable), secure API communication only for crash reporting, and regular security reviews.
Retention: Since all project data lives on your device, you can clear app data or uninstall the App to permanently remove all information at any time.
Fexo Subtitle Studio requests only the permissions necessary to deliver its subtitle creation and export features. Below is a full breakdown:
| Permission | Why It's Required |
|---|---|
| Internet Access | Allows the app to connect to the internet to load app content, ads, and online features. Your videos and subtitles are never uploaded. |
| Keep Screen Awake | Keeps the device awake while certain features are running, such as long subtitle exports, so they are not interrupted. |
We use limited third-party tools solely to maintain app quality:
This app uses code of FFmpeg (ffmpeg.org) and libmpv (mpv.io), licensed under the LGPL v3.0. These libraries run entirely on your device for video analysis, playback, and export; their source code can be obtained from their project websites. The app also includes open-source packages under MIT, BSD-3-Clause, and Apache-2.0 licenses.
No advertising SDKs, no tracking SDKs for cross-app profiling, and no data brokers. Your recordings stay yours, always.
Depending on your region (GDPR, CCPA, etc.), you have rights over your data. Since all user-generated content is stored locally:
Fexo Subtitle Studio is not directed to children under 13. We do not knowingly collect personal information from minors. If a parent or guardian becomes aware that a child has provided us with information, please contact us and we will ensure data is promptly removed. Camera and microphone permissions should be used under parental guidance for younger users.
We may update this policy to reflect operational, legal, or technical changes. The "Effective Date" at the top indicates the latest revision. Continued use of the app after changes constitutes acceptance. For significant updates, we will notify you via in-app notice or on our website.
If you have any questions about this Privacy Policy, your data, or how we handle permissions, please reach out — we're happy to help.
