Sound Sharp collects the following information when you use our app:
Account information: email address and display name (and the name Apple shares if you sign in with Apple)
Profile photo, if you add one (from your camera or photo library)
Audio recordings you make for analysis
Transcripts, scores and feedback for your answers
Voice measurements from your recordings: how much your pitch moves and how your volume changes, relative to your own voice (not a voiceprint)
Your interview setups (field, role and interviewer style; up to 3), and a company name and job posting for each if you add them. Your setups, question lists, company names and job postings are kept on your phone; only the setup in use (field, role and interviewer style) is stored with your account, along with the one used for each AI conversation or mock interview. The company and job posting are sent to Anthropic with your answers and question requests (with your current question list when you ask for a new set). They are not stored on their own, but questions and feedback written for that job, which can name the company, are stored with your results.
Questions you type are stored with your answers, like any question you practice, and with any mock interview that asks them.
Your interview date, if you add one
The one skill you're working on and how it's going, worked out from your results
Conversation answers and the AI's replies
Usage data: practice sessions, streaks and your time zone
Device push notification tokens, if you allow notifications
Subscription status and App Store purchase history
2. How We Use Your Information
We use your information to:
Analyze your speech and give coaching feedback
Measure your voice (pitch movement and loudness) on our own servers to give you voice feedback. No AI service or other company receives anything for this, and we never use it to identify you.
Suggest interview questions and vocabulary
Track your progress and streaks
Keep track of the skill you're working on and pace your prep for an interview date
Send practice reminders and weekly summaries (if enabled)
Manage your subscription
We do not sell your data, and we do not use it to train AI models.
3. AI Services and Your Permission
Before anything is sent to an AI service, the app asks for your permission. You can withdraw it at any time in Profile → AI processing; nothing more is sent after that.
AssemblyAI receives your voice recordings and turns them into text, with filler words and timing. We delete each transcript from AssemblyAI as soon as the analysis is done.
Anthropic (Claude) receives your transcripts and the questions you answer (including ones you type), interview setup (including any company and job posting you add), conversation answers and short notes from your earlier answers (the skill you're working on and where you started on it, the advice you were given last time on the same question, your measured pace and filler rate, and which STAR parts that answer had), and writes your feedback, questions and replies.
4. Other Services We Use
Google Firebase: sign-in, data storage, server functions, and notifications on Android
Apple: Sign in with Apple and notifications on iPhone
RevenueCat: subscription management (your account ID and App Store purchase history)
Mock interview questions and the word of the day are read aloud by your phone's built-in text-to-speech. On iPhone this stays on the device; on Android your phone's speech engine may use an online voice, depending on its settings. Only that text is spoken.
5. Data Storage & Security
Your data is stored in Google Firebase. Audio recordings are stored in Firebase Cloud Storage. The app plays each one through an unlisted web address given only to your account; anyone given that address could play the recording. Your profile photo is stored at an unlisted web address so the app can show it; anyone given that address could open it. Data is encrypted in transit and at rest.
6. Data Retention
Your recordings, results and history are kept while your account is active
Deleting your account removes all of them, including your recordings, profile photo and sign-in records
Transcripts are deleted from AssemblyAI once each analysis is done
Voice measurements are kept with each result and deleted with your account
The word of the day is cached for 24 hours
7. Your Rights
You can:
Delete your account and all its data at any time in Profile → Delete Account
Withdraw permission for AI processing in Profile
Turn off notifications in Profile or in your device settings
Ask us for a copy of your data, or ask any question about it
