Who provides the app
AfterLogic Corporation provides Ivories.music, a piano note-reading game called Guess the Note. This policy covers the current local-only iOS app and these Privacy and Support pages. No Ivories account is required.
For privacy questions, contact a.nefedov@gmail.com.
Practice data
The app stores note-reading results, response times, mistakes, your color map, level progress and practice preferences in local app storage. It also remembers your selected input and presentation preferences. This information is used to run practice, adapt note selection and show your progress.
The app does not upload this practice history to an Ivories or AfterLogic server. It has no custom analytics or advertising SDK and does not track you across other companies’ apps or websites.
Microphone and instrument input
Microphone input is optional. When you choose it, grant permission and start or resume practice, audio is analyzed on your device to identify piano notes. Audio is not recorded to a file or uploaded. Pausing practice, opening Practice settings or leaving the active app stops input capture.
In builds where a MIDI instrument connection is enabled, note events are processed locally. The app does not save an audio or MIDI recording or upload the input stream.
You can revoke microphone permission in iOS Settings. You can use the on-screen keyboard without granting microphone or instrument permissions.
Storage, backups and deletion
Individual answer observations are retained for a rolling 90-day period and removed when the app next reads or writes practice history. Your compact color map and level progress can remain until you reset them.
Practice settings → Reset heat map deletes the local answer history, color map and level progress after confirmation. Input and presentation preferences remain. This reset cannot be undone by us.
iOS may include app storage in device backups according to your Apple settings. Ivories does not provide its own cloud backup, account sync or remote recovery. We cannot remotely inspect or delete your on-device practice database; you control the local reset.
Apple diagnostics and TestFlight
Apple operates the App Store, iOS diagnostics and TestFlight separately from Ivories. Apple may provide developers with app analytics and diagnostic information under its own privacy terms and your applicable settings.
If you install a beta through TestFlight, Apple collects beta usage and crash information and shares reports with AfterLogic. These reports may identify the tester and device. Feedback you choose to submit may include screenshots and comments. We use these reports to investigate problems and improve the app; we do not routinely copy them into a separate analytics service.
See Apple App Analytics & Privacy and TestFlight & Privacy. Apple controls retention of records in its services.
When you contact support
If you email us, we receive your email address, message and any attachments you choose to send. We use them to respond, investigate the issue and manage your request. Email is processed by the email services used to send and receive it.
We retain support correspondence while needed to handle the request and related follow-up, or to meet applicable legal obligations. You can use the contact address above to request access, correction or deletion of information you have sent us. We will explain any information we must retain. Please do not send passwords, sensitive recordings or unrelated personal information.
