No. Voice conversations are transcribed in real time; the audio is never saved — not by us, and not by our voice provider (audio storage is disabled at the account level). What exists after an interview is the written transcript, nothing else. For interviews at physical venues, location is checked once at the start — only the yes/no verification result is kept, never coordinates.
The business that runs an interviewer is responsible for the interviews it collects and is the controller of that data. Proust is the processor: we run the conversation, transcribe it, and analyze it on the business’s behalf and on its instructions. The business controls how long transcripts are kept and can delete them at any time. Deleted data is removed from the live database immediately; short-lived backup copies expire on a fixed schedule.
Businesses see transcripts, themes, and quotes — never a participant’s name, email, phone number, or payout details.
Proust is the controller of two narrow things: merchant account data (your login email, billing) and participant reward data (the email, or the Venmo phone number or PayPal email a participant gives us to get paid). We use reward data to pay rewards and prevent fraud — nothing else. We do not sell personal data, and we do not use it for advertising.
Neither we nor our AI providers use your conversations to train AI models.
Yes. By agreeing to our terms when creating a Proust account, businesses also agree to our Data Processing Agreement. It is not necessary to sign a separate document.
These are the services Proust runs on. The column that matters: whether a vendor reads or hears conversations. We give 14 days’ notice before adding a vendor that does.
| vendor | what it does | where | reads or hears conversations? |
|---|---|---|---|
| Railway | Application hosting and database | US | Yes — transcripts are stored in our database on Railway, encrypted at rest |
| Anthropic | The AI that conducts and analyzes interviews | US | Yes — processes conversations to run them; does not train on them |
| ElevenLabs | Voice conversations (speech in, speech out) | US | Yes (voice interviews only) — audio storage disabled; its transcript copy auto-deletes in 30 days |
| Vercel | Web page hosting | US | In transit only — conversations pass through, nothing is stored |
| Resend | Transactional email (reward claims, sign-in) | US | No — email addresses only |
| Trolley (Trolley Inc.) | Reward payouts, paid to Venmo or PayPal | US | No — payout contact details only (Venmo phone number or PayPal email) |
All data is encrypted in transit (TLS) and at rest. Interview links are single-session tokens — the printed QR contains an opaque identifier, never data. Access to production systems is limited to the founders. The website uses no analytics scripts and no tracking cookies.
Businesses: delete interviews or your whole account from the dashboard, or email us. Participants: email privacy@proust.dev from the address you used to claim a reward and we’ll delete your data within 45 days. See also the participant page.
