4. Audio Recordings
When you use the conversation practice, roleplay, or placement test features, we access your device's microphone to record your speech. These recordings are:
- Sent to OpenAI and/or Deepgram for speech-to-text transcription and AI-generated responses
- Not stored permanently on our servers after processing
- Used solely for the purpose of providing language learning feedback
You can deny microphone access at any time through your device settings, though this will limit the app's conversation practice functionality.
5. Data Security
We implement appropriate technical and organizational measures to protect your personal information. However, no method of electronic transmission or storage is 100% secure, and we cannot guarantee absolute security.
6. Data Retention
We retain your personal information for as long as your account is active or as needed to provide you services. You can delete your account and all associated data (saved words, phrases, conversations, decks, and progress) at any time from Settings > Delete account within the app, at polyspeech.ai/delete-account, or by contacting us at the email address below.
