VoiceFlow Privacy Policy

Last updated: March 22, 2026

        Summary: VoiceFlow keeps a history of your transcribed texts on your device so you
        can re-use them later. Your voice recordings are never saved — only the resulting text is stored.
        All API keys are encrypted. No data is sent to our servers.
    

Information We Collect

VoiceFlow stores the following data locally on your device:

Transcription history: The last 20 transcribed texts are saved on your device so you can view and re-use them from the History screen. This text is stored only in your device's app storage and never sent to us or any third party. History is never recorded when you dictate into a password field.
API keys: Your Groq, Gemini, and Sarvam API keys (whichever you configure) are stored on your device using Android's encrypted storage (AES-256). They are never transmitted to us.
App settings: Your language preferences, customization settings, and other in-app choices are saved locally on your device.

Voice recordings are never saved to storage. Audio is captured in memory, processed, and immediately discarded.

How We Use Your Information

Your voice recording is sent to one of the following services depending on which engine you have selected in Settings:

Groq Whisper (Cloud): Voice is sent to Groq's Whisper API for transcription.
Google Gemini (Cloud): Voice is sent to Google's Gemini API for transcription and optional formatting in a single call.
Sarvam AI (Cloud): Voice is sent to Sarvam AI's API for transcription, optimised for Indian languages.
Offline Mode: Voice is processed entirely on your device using a local AI model (IndicConformer or Whisper Local). No audio or text leaves your phone.

The resulting text is inserted into the active app and saved to your on-device History (unless you were typing into a password field). We do not use your data for any other purpose.

Third-Party Services

Depending on your chosen engine, your voice recording may be sent to one of these services:

Groq API: Speech-to-text transcription. See Groq's Privacy Policy.
Google Gemini API: Speech-to-text and text formatting. See Google's Privacy Policy.
Sarvam AI API: Speech-to-text for Indian languages. See Sarvam's Privacy Policy.

If you use Offline Mode, no audio or text is sent to any external service.

Data Security

API keys are stored using Android's EncryptedSharedPreferences (AES-256-GCM).
All network communication uses HTTPS encryption.
Voice recordings are never saved to disk — processed in memory only.
Transcription history is stored only in your device's private app storage.
No data is sent to our servers — we don't have any.
When using Offline Mode, nothing leaves your device at all.

Data Retention

VoiceFlow retains the last 20 transcribed texts on your device in the History feature. You can clear this at any time using the Clear History button. Voice recordings are never retained — they are processed in memory and immediately discarded after transcription.

Your Rights & Control

Clear history: Open the History screen and tap "Clear All" to delete all saved transcriptions immediately.
Delete API keys: Go to Settings → API Configuration and clear any key at any time.
Full deletion: Uninstalling the app removes all locally stored data, including history, API keys, and settings.

Children's Privacy

VoiceFlow does not knowingly collect personal information from children under 13. Since we do not operate any servers, no data from any user (including children) is transmitted to us.

Changes to This Policy

We may update this policy occasionally. Significant changes will be communicated through app updates.
