AI provider details

Personalang powers Lucia's memory, coaching, and live conversation experience. To deliver live voice sessions, we use specialized AI infrastructure providers for transcription, response generation, coaching, and voice audio.

What is sent during a live session

When you start a live session, the following data may be processed by Personalang and the AI providers listed below:

• Voice audio from the session, used to transcribe what you said.
• Transcript text from your conversation, used to generate Lucia's replies, coaching, and memory updates.
• Language settings, such as your target language and coaching language.
• Relevant memories and conversation context, used so Lucia can respond with continuity instead of starting from scratch.
• Lucia's reply text, used to create the voice audio you hear.

Recordings are separate

We believe you should decide what happens to your data. Live processing is required for a voice session, but saving a replay recording is different. Recordings can help improve session quality and learning continuity, but they are optional and off by default. We save a replay recording only if you turn on the recording option before a session, and you can turn it off again at any time.

How providers may use this data

These providers process data on our behalf to provide Personalang's features. They are not permitted to use Personalang user data for advertising. We require providers we use to protect personal data under confidentiality and data-protection obligations that provide the same or equal protection described in our Privacy Policy.

Our providers include OpenAI, Google Gemini, and Cartesia.

Your choices

Before your first live voice session, Personalang asks you to agree to this live voice and third-party AI processing. You can withdraw voice data consent in Settings. You can also delete your account, conversations, recordings, and memories from Settings.
