Privacy Policy
Last updated: 28 August 2026
Baritone (Umang Singh, "we") measures acoustic properties of your speaking voice and gives you a training programme. This policy explains exactly what we collect, what we do not, and why.
The short version
- Your recordings are deleted. Audio is analysed the moment it arrives and removed in the same request. We never store it, and there is no setting to keep it, because we have not built one.
- We keep the measurements, not the recording. Numbers like your median pitch and voice steadiness — never anything you can listen to.
- The app does not know who you are. No name, no account, no phone number. Your device generates a random identifier and that is all we hold.
- If you gave us your email on the website, that is the one thing we hold that has your name on it — and it is not connected to the app at all.
- Your quiz answers stay on your phone.
- We do not sell your data, and we do not show you ads. We buy advertising to tell people Baritone exists, like anyone else does. What we do not do is use anything you give us to target it, or let an ad network follow you here.
What we collect
Voice recordings — processed, then deleted
When you record the passage, your phone sends us two audio files: the passage and about three seconds of room tone. We measure them and delete both before the request finishes. They are never written to a database, never backed up, and never sent anywhere else.
We are not identifying you by voice. We measure physical properties of a sound — pitch, steadiness, clarity, resonance — the way a tape measure reads a length. We do not build a voiceprint, we do not attempt to recognise you from a recording, and we cannot match one person's recording to another's.
Measurements — kept
We keep the numbers extracted from each recording, which is what makes a progress graph possible. For each scan:
| We store | Example |
|---|---|
| A random scan id | scn_a41f09c2 |
| Your random device id | u_m8x2p91k |
| When it was recorded | 2026-08-24T09:07:00Z |
| Which norms you asked to be compared against | male / female |
| Which direction you are training toward | deeper / brighter |
| Which microphone you used | builtin / wired / bluetooth |
| The measurement vector | median pitch in Hz, steadiness, clarity, resonance and pace figures |
What we never receive
Your quiz answers — your age band, what you use your voice for, your habits, your self-rating, which voice you are aiming for — never leave your phone. They personalise what the app says to you, locally. Only your comparison group, your goal and your microphone type are attached to a recording.
Your streak, XP and completed days are also stored only on your phone.
Purchases
If you subscribe, Apple processes the payment. We never see your card, your Apple ID, or your billing address. Our payments provider (RevenueCat) tells us that a purchase, renewal, cancellation or refund happened, tied to the same random device id — so we can unlock the app and understand how many people are refunding.
Analytics
We record which screens you reach and which steps you complete — for example that a score card was shown, or that a drill was finished — tied to the same random device id. We use this to find where the app is confusing. We do not track you across other apps or websites, and we do not use advertising identifiers.
Who else touches your data
| Who | What they get | Why |
|---|---|---|
| Our server (Hetzner Online GmbH, Falkenstein, Germany) | Audio, momentarily; then the measurements | To score your voice |
| Anthropic (Claude) | The numbers only, as text | To write the short explanation on your card |
| RevenueCat | Your random device id, purchase events | Subscriptions |
| Apple | Payment details, directly from you | Payment processing |
| Mixpanel | Your random device id, app events | Product analytics |
The service that writes your card's explanation receives numbers as text and never receives audio. It is given your pitch and your sub-scores; it is not given anything you said, because we do not send it the recording.
How long we keep things
- Audio: deleted within the request. Seconds.
- Measurements and scan history: until you ask us to delete them, or the service shuts down.
- Purchase records: as long as required for tax and accounting.
- On-device data: until you delete the app.
Your choices and rights
- Delete everything: email support@trybaritone.com from the device you use, or use the delete option in Settings. Deleting the app removes everything held on your phone; ask us to remove your server-side scan history.
- Get a copy of your data: email support@trybaritone.com.
- Turn off reminders: in Settings, or in iOS notification settings.
Depending on where you live you may have rights to access, correct, delete, port, or object to processing of your data (for example under the UK/EU GDPR, the CCPA/CPRA in California, or India's DPDP Act). Email support@trybaritone.com and we will action it.
Children
Baritone is not directed at children under 18 and we do not knowingly collect data from them. If you believe a child has used the app, email support@trybaritone.com and we will delete the associated records.
Baritone is rated 18+ on the App Store and the onboarding offers no under-18 age band. We do not knowingly collect data from anyone under 18.
This is deliberate rather than incidental. Under India's Digital Personal Data Protection Act anyone under 18 is a child, which requires verifiable parental consent and bars behavioural monitoring — and this app records voice and measures product usage. Serving minors properly is a different product, not a wider funnel.
This is not a medical service
Baritone is a training and self-improvement app. It does not diagnose, treat, or assess any medical or voice condition, and nothing it shows you is a clinical finding. If your voice is persistently hoarse, tires quickly, or hurts to use, see an ENT or a speech-language pathologist.
Changes
If we change what we collect we will update this page and the "last updated" date, and say so in the app.
