Voxio
Privacy Policy
Last Updated: January 25, 2026
Voxio (“we”, “our”, “us”) is a language learning application that helps you practice speaking through AI-powered conversations. This Privacy Policy explains what data is processed when you use the app and how it is handled.
Summary
- We do not require an account, and we do not collect your name or email by default.
- Your conversations and settings are primarily stored locally on your device.
- When you use features like speech-to-text, text-to-speech, and AI chat, your audio/text is sent to our API and then to OpenAI for processing.
- We store minimal server-side data to support app functionality (such as daily usage time, premium status, and basic settings).
Information We Process
Information you provide
- Audio recordings you choose to record for speech-to-text (if you use that feature).
- Text input you send during conversations (messages, prompts).
- Preferences such as selected language, difficulty, voice choice, and practice settings.
Information processed automatically
- Device-generated user ID (a random identifier created on your device to link usage and settings; it is not your real-world identity).
- Usage statistics such as daily practice time and conversation counts (used for limits and progress).
- Premium status (whether premium features are enabled).
How We Use This Information
- Provide core services: speech-to-text, AI responses, text-to-speech, and feedback features.
- Improve your experience: remember your preferences and show your progress.
- Usage tracking: support daily usage limits for free users and track practice duration.
Third-Party Services
OpenAI
Voxio uses OpenAI services to process audio and text and generate responses (e.g., transcription, chat responses, and text-to-speech). The data you submit for these features is sent to OpenAI for processing. OpenAI’s handling of data is governed by their policies. We send only the data necessary to provide the requested feature.
Cloudflare
Our API is hosted on Cloudflare (Workers). We may store minimal app-related data in a Cloudflare D1 database, such as usage totals, premium status, and settings. Cloudflare processes requests and provides infrastructure services.
Data Storage
Stored locally on your device
- Conversation history and transcripts (if enabled in the app)
- Language preferences and settings
- Weekly goals and progress
This local data stays on your device unless you delete it or uninstall the app.
Stored on our servers (minimal)
- Device-generated user ID
- Daily practice time (seconds per day)
- Premium status
- Optional settings (stored as JSON)
Audio data
Audio recordings are transmitted for real-time processing when you use speech-to-text. We do not intentionally store raw audio files on our servers as part of normal app operation.
Data Retention
- Local data: stored until you delete the app or clear app data.
- Server-side minimal data: retained as needed to operate the app (e.g., usage limits, premium status). You may request deletion (see below).
Your Rights and Choices
- Access: you can view most information (history/settings) inside the app.
- Delete local data: uninstalling the app removes locally stored data.
- Request deletion of server-side data: contact us and include your device-generated user ID.
- Control recording: you control when audio is recorded and sent.
Security
Data in transit is encrypted using HTTPS. We use reasonable technical measures to protect the services we operate. No method of transmission or storage is 100% secure.
Children’s Privacy
Voxio is not intended for children under 13. We do not knowingly collect personal information from children under 13.
International Processing
Your data may be processed by service providers in countries other than your country of residence.
Changes to This Policy
We may update this Privacy Policy from time to time. We will update the “Last Updated” date above when changes are made.
