Privacy Policy
Last updated 14 November 2026
Evolcent is a voice app for practicing spoken American English with an AI coach named Ava. This page says what we collect, who receives it and how to remove it. Evolcent is for adults aged 18 and over.
What we collect
- Your email address, to sign you in. If you continue with Google or Apple, they share your email with us, and may share your name and picture, which are kept with your sign-in.
- If you ask for early access on evolcent.com, your email address and the call style you picked, so we can email you once when the app is ready.
- Your voice during calls and practice, and Ava’s voice, recorded so you can replay them.
- Transcripts of what you say, messages you type in a call, pronunciation scores, call summaries and practice results.
- What you tell us in your profile: first language, level and reasons for learning.
- Notes Ava keeps between calls (facts you mention, open threads and a one-line summary). She avoids health, religion, politics, sexuality and money unless you ask her to remember them. You can view, edit, delete or turn off these notes in the Memory panel.
If you allow it, your camera image stays on your device: it shows you your own picture in a call and is never sent to us. During a call we make a temporary voiceprint so that Ava can ignore other people talking near you. It is not stored after the call.
We do not use advertising, sell your data or track you across other apps and websites.
AI and other service providers
Evolcent works by sending your data to the companies below. We ask for your permission in the app before your first call, and no call starts without it. You can withdraw it in Settings, which stops new calls.
| Provider | What it receives | Why |
|---|---|---|
| OpenAI | Transcripts, your profile, Ava’s notes | Writes Ava’s replies, summaries, notes and translations |
| Anthropic | Same as OpenAI | Backup when OpenAI is unavailable |
| Microsoft (Azure) | Your voice | Turns your speech into text |
| Your voice, Ava’s replies | Ava’s backup voice, and hosts our pronunciation scorer | |
| DeepInfra | Ava’s replies | Speaks Ava’s replies |
| OpenRouter | Your voice, and the same as Google and Anthropic | Backup for speech to text, and a backup route when Google or Anthropic is unavailable |
| Prime Intellect | Your voice, through OpenRouter | Runs the backup speech-to-text model |
| LiveKit (with Krisp) | Your voice, Ava’s voice | Carries the call and removes background noise |
| Supabase | Email, recordings, transcripts, scores, notes | Sign-in, database and recording storage |
| Google and Apple | Nothing from your calls; only that you are signing in | Sign-in, if you choose it |
| Render and Vercel | Requests as they pass through | Host our service and website |
| Cloudflare | Requests as they pass through, and your email if you ask for early access | Hosts evolcent.com and keeps the early-access list |
We do not allow these providers to use your data for anything but providing their service to Evolcent, within the terms they offer API customers. We do not use your recordings to train AI models.
How long we keep it
- Recordings: deleted 24 hours after they are made.
- Transcripts, scores, summaries, profile and notes: until you delete them or your account.
Your choices
We keep a record that you agreed to send your voice and words to the AI providers above, and when. To withdraw, go to Settings, then Voice and privacy, and turn off the Recording notice. That pauses any call in progress, and we won’t send your voice again unless you agree again.
To delete your account, go to Settings, then Privacy and account. It removes your profile, calls, recordings, notes and sign-in right away. To ask for a copy of your data or to ask anything else about privacy, email support@evolcent.com.
Children
Evolcent is not for anyone under 18. If you believe a child has used it, email us and we will delete the account.
Changes
If this policy changes in a way that affects your data, we will ask for your permission again in the app.
