Privacy Policy

Effective November 13, 2026 · applies to the Practice Studio app for iPhone and iPad (beta, version 0.1) and this website.

1. What stays on your device

Microphone

The app uses the microphone for the tuner and the recorder. Sound is analyzed on your device while you play. The app does not send audio anywhere. You can turn microphone access off at any time in the iOS Settings app.

Recordings

Recordings are saved in the app's own folder on your device. You can also see them in the Files app (On My iPhone or On My iPad › Practice Studio). When you delete a recording it goes to Recently Deleted for 30 days and is then removed for good.

If you back up your device to iCloud or to a computer, your recordings are included in that backup like your other files. Apple or your computer handles that backup under your own account, and we can't see it.

Settings

Your choices, such as your instrument, the A4 reference pitch and which recordings you starred, are saved on your device.

App log

The app keeps a small log of what it did, so problems can be fixed if you decide to send a report. It records things like which screen was open, tuner readings (note, cents and frequency), metronome tempo, audio errors, and your device model and iOS version.

It never contains sound, recording names or anything you type. It is kept below about 1 MB (older lines are removed), stays on your device, is left out of device backups, and is deleted when you delete the app. It only leaves your device inside a problem report that you choose to send.

2. What we receive, only when you choose to send it

Problem reports

In the app you can tap Report, write what went wrong and tap Send. This opens the Mail app, or the share sheet if Mail isn't set up, with a message ready for you. Nothing is sent until you send it yourself from Mail or from the app you pick in the share sheet. The report contains:

• what you wrote;
• your device model, iOS version, app version and build, free storage, whether the app has microphone permission, and which screen and layout the app was showing;
• the app log described above;
• your most recent recording, only if you turn on Attach my last recording. This is off by default.

Because a report is an email, we also receive the email address you send it from, and any name your email account shows.

Emails you write to us

If you email us, we receive your message, your email address and anything you attach.

How we use and keep what you send

We use reports and emails only to answer you and to fix problems in the app. Our inbox is hosted by Google (Gmail), so Google stores those emails for us. We don't share them with anyone else. We delete a report once the problem is solved, and at the latest one year after we receive it. You can ask us to delete it sooner at any time.

Sharing recordings

When you use the share button on a recording, it goes to the app or person you choose, not to us.

TestFlight (Apple)

If you install the beta through Apple's TestFlight, Apple may share with us crash reports and any feedback or screenshots you send through TestFlight, as described in Apple's TestFlight terms. Apple's own privacy policy covers what Apple collects.

3. Children's privacy

Practice Studio is made to be used by children who are learning an instrument. The app does not collect personal information from children: it has no accounts, no sign-up and no chat, and it doesn't send anything on its own.

The only way information reaches us is an email (including a problem report) that someone chooses to send. For children under 13 in the United States (COPPA) and under 14 in Korea (Personal Information Protection Act), we ask that a parent or guardian send the report or email, or send it together with the child.

If we learn that we received personal information from a child without a parent's consent, we delete it. A parent or guardian can email us at any time to ask what we received and to have it deleted.

4. Your choices

• Microphone: turn it off in Settings › Apps › Practice Studio (the tuner and recorder won't work without it).
• Recordings: delete them in the app or in the Files app.
• Everything on the device: deleting the app removes its recordings, settings and log from the device. Copies in your own device backups stay until those backups are replaced or deleted.
• Things you sent us: email us to see or delete them.

5. This website

This website uses no cookies, no analytics and no scripts. It is hosted by Cloudflare, which handles technical information such as IP addresses to deliver the pages and protect the site from attacks, under Cloudflare's privacy policy. We don't use that information to identify you.

6. Changes

If the app starts handling data differently, we will update this page and the date at the top before that version is released, and mention it in the release notes.
