Confidence Labs (Lee Nguyen) · Last updated: September 10, 2026

Confidence Labs makes three practice apps: Rehearse – Sales, Rehearse – Interview, and Rehearse Social (listed as “Rehearse: Small Talk & Social” on the App Store and “Social Anxiety” on Google Play). The short version, true across all three: your voice is used only to power the conversation you asked for and is not stored as a recording, we don't sell your data, and payment details never reach us. The details for each app are below, followed by a section about this website itself.

What all three apps have in common

Accounts. You sign in with an email address, managed by Firebase Authentication (Google). Passwords are encrypted and never stored in plain text.
Voice audio. When you speak during a practice session, your audio is transcribed in real time by OpenAI's speech-to-text and immediately discarded. We do not store, retain, or have access to your voice recordings.
AI processing. Conversation text is processed by third-party AI services (OpenAI and Anthropic) to generate your practice partner's replies, and Fish Audio converts reply text into the voice you hear. Requests go through our secure server; each provider receives only what it needs, and OpenAI and Anthropic do not use API data to train their models.
Subscriptions. Purchases are handled by the Apple App Store or Google Play together with RevenueCat. We never see your payment card details.
No selling, no ads. We do not sell your personal information and do not use your conversations to advertise to you.
Product analytics. Each app sends a small stream of product events to our own servers (Google Firestore) so we can see where people get stuck: app first opened, an onboarding step viewed, sign-up, a practice session started or finished, the upgrade screen shown, a purchase completed, and a handful of technical events such as the microphone receiving no input. Each event carries a random install identifier, your account id once you are signed in, the app version and platform, and small details such as which scenario or how many exchanges. No conversation content and no audio is ever included.
Children. The apps are not directed at children under 13, and we do not knowingly collect data from them.

Rehearse – Sales

In addition to the common practices above:

Account information: email address, first and last name.
Subscription status: account tier (Free, Trial, or Pro) and trial sessions used.
Conversation content: the text of your practice conversations is processed in real time and is not stored on our servers — it exists only during your active session.
Document upload (Practice a Real Account): if you upload a company PDF, the file itself is read once and then discarded — we never store the file, and it is never sent to an AI provider; only text extracted from it is used as session context. The practice scenario built from it (the company name and the scenario description used to run the roleplay) is saved to your account so you can practise that account again. You can delete a saved account at any time in the app.
Practice history and debriefs: your session history, the written debrief after each call, streaks, and achievements are kept on your device, not on our servers. You can clear them in the app or by uninstalling. This is separate from the product events described above.

Rehearse – Interview

Interview stores more than Sales does, because reviewing a past round is the point of it:

Account information: email address, first and last name.
Subscription status: account tier and trial sessions used.
Interview history: when you complete a round, that round is saved to your account so you can review it: the job posting details, your feedback and scores, per-answer metrics, and the transcript of the round (what you said and what the interviewer said). It is kept until you delete the interview or your account.
Job postings and résumés: postings you save and any résumé you add are stored in your account so the interviewer can be built from them.
Practice statistics: round analytics and streaks are stored with your account so your progress screens work across devices.

In addition to the common practices above:

Account information: email address (Firebase Authentication, or Google Sign-In if you use it).
Profile answers: the situations, challenges, and goals you select during onboarding, used to generate your personalized practice plan.
Practice data: generated scenarios, session history and statistics, confidence check-ins, and real-life challenge progress — retained while your account is active so your progress is preserved.
Documents you upload: parsed on our own server; the file is not sent to any AI provider, and only the extracted text is used as session context.
Third-party AI disclosure: before your first session the app shows exactly what is sent to OpenAI (your voice audio, for transcription), Anthropic (conversation text, scenario, and goals, to generate replies), and Fish Audio (the AI partner's reply text, for speech) and asks for your permission.

Not a medical service. Rehearse Social is a practice tool, not mental health treatment, and conversations are not reviewed by clinicians. If you are experiencing clinical anxiety, depression, or another mental health condition, please consult a licensed professional.

This website

The confidencelabs.app website is a static site with no accounts and no forms — we never ask you for personal information here. It does run two Google measurement tags on every page: Google Analytics 4, so we can see which pages people read, and a Google Ads conversion tag, which records when a visitor taps through to the App Store or Google Play. Both set cookies in your browser and both are governed by Google's privacy policy. We use them only in aggregate — we do not build advertising profiles, we run no remarketing lists, and we do not attempt to identify you. You can block them with any content blocker or your browser's tracking protection and the site will work normally.

Your rights and deletion

You can access and update your account information in each app, and delete your account and associated data at any time — use the app's account features or email support@confidencelabs.app and we will complete deletion within 30 days.

Changes

If we make material changes to this policy, we will update this page and the date above.
