Privacy Policy

Last updated: October 16, 2026

1. Introduction

CODAA (the “App,” “we,” or “us”) is an application offering audio processing tools and supporting music education, practice, and creation on compatible devices.

We respect users’ privacy and are committed to transparency in the collection, use, storage, and protection of personal data.

This Privacy Policy explains how CODAA processes information when users access and use the App, including free features, paid subscriptions, and integrated third-party services.

By using CODAA, users acknowledge that they have been informed of the data processing activities described in this Policy. Where consent is required by applicable law, CODAA will request separate consent as necessary.

2. Privacy Protection Principles

CODAA is developed with a preference for processing data directly on users’ devices (Local-first Processing).

Accordingly:

• Audio analysis and processing tasks are preferably performed on the device.

• Personal recordings or music files do not need to be uploaded to CODAA servers for locally processed features.

• We do not access or collect the contents of users’ music libraries without authorization.

• We request access only to resources necessary for features that users actively choose to use.

• We do not sell users’ personal data or audio content to third parties.

• We do not use personal recordings to train artificial intelligence models without an appropriate legal basis and consent.

Local processing does not rule out the possibility that advertising, payment, notification, or technical diagnostic services may process certain data under the separate terms described below.

3. Information and Data Processed

3.1. Audio Files and Music Data

CODAA may process data actively selected or created by users, including:

• Audio files and recordings.

• Pitch, note duration, rhythm, chord, and musical structure data.

• MIDI, MusicXML, and other supported music formats.

• Editing and arrangement projects and audio settings.

• Vocal training, vocal range assessment, and music practice results.

Such data is preferably processed and stored on the device.

CODAA does not transfer personal audio content to the developer’s servers by default.

When users choose to export, share, or synchronize files through external services, subsequent processing may be governed by the privacy policies of those services.

3.2. Microphone Data

Some features require microphone access, including:

• Audio recording and analysis.

• Pitch and chord recognition.

• Vocal warm-up and vocal range assessment.

• Ear training, rhythm training, and sight-singing practice.

• Music tools requiring an audio input signal.

CODAA uses the microphone only when needed for the relevant feature and when permission has been granted by the operating system.

Users may revoke microphone access at any time in their device settings.

Revoking permission may prevent certain features from functioning.

3.3. Device Information and Technical Data

CODAA and integrated services may process certain technical information to maintain operation, troubleshoot issues, and improve stability, such as:

• Device type and operating system version.

• App version.

• Performance information and crash reports.

• Network connection status.

• Device identifiers or app instance identifiers where necessary for the relevant service.

The actual scope of data depends on the App configuration, user permissions, and integrated SDKs.

3.4. Music Learning and Practice Data

For Pageno Music features, CODAA may process:

• Vocal range and voice settings.

• Pitch, intensity, and audio duration analysis results.

• Practice scores and progress.

• Practice history and exercise results.

• Personal settings used for learning.

This data is used to provide feedback, assess results, and personalize the practice experience.

CODAA does not share personal practice data with educational institutions, teachers, or professional partners by default. Sharing occurs only when users actively use an export or sharing feature, or where an appropriate legal basis exists.

4. Purposes of Data Processing

CODAA processes data only for purposes consistent with the App’s operation, including:

• 1. Providing audio processing and analysis features.

• 2. Storing projects, settings, and practice results.

• 3. Managing access to features according to subscription plans.

• 4. Displaying advertisements and managing the advertising experience.

• 5. Sending App-related notifications when permitted by users.

• 6. Detecting, diagnosing, and resolving technical errors.

• 7. Maintaining safety and security and preventing misuse of services.

• 8. Complying with legal obligations where necessary.

We do not use users’ personal audio content for commercial purposes beyond those disclosed and authorized.

5. Advertising and Third-Party Services

CODAA may integrate Google AdMob or other advertising platforms to support and develop free features.

Depending on advertising settings, jurisdiction, and users’ privacy choices, advertising providers may process certain data, such as:

• Advertising identifiers, where permitted.

• IP addresses and connection information.

• Device and App information.

• Advertising interaction data.

• Diagnostic and advertising performance measurement data.

On Apple devices, CODAA will request permission through App Tracking Transparency when tracking activities fall within Apple’s requirements.

Users may decline tracking permission. Doing so does not prevent the use of CODAA’s basic features, but may affect ad personalization.

Data collected and processed by advertising providers may be subject to their own privacy policies.

6. Subscriptions and Payments

CODAA offers subscription plans such as CODAA Elite and CODAA Premium.

In-app purchases and subscription renewals are processed through the payment systems of the relevant distribution platforms, such as the Apple App Store or Google Play.

CODAA does not directly collect or store users’ complete payment card details through these systems.

The App may receive and process information necessary to determine subscription status, feature entitlements, validity periods, and transaction status.

Subscription management, cancellation, and renewal are governed by the rules of the relevant payment platform.

7. Push Notifications

CODAA may use notification services such as Firebase Cloud Messaging (FCM) or Apple Push Notification service (APNs).

When users allow notifications, the App and service providers may process a device push token and other technical information necessary to deliver notifications.Local-first Processing

Notifications may concern feature updates, service changes, subscription information, or other content consistent with users’ choices.

Users may disable notifications at any time in their operating system settings.

8. Artificial Intelligence and Audio Analysis

CODAA may use digital signal processing algorithms, machine learning models, and artificial intelligence technologies to support:

• Pitch, rhythm, and chord analysis.

• Audio signal recognition and processing.

• Vocal and instrumental separation.

• Speech or audio content recognition.

• Sheet music analysis and practice assistance.

These features are designed to prioritize on-device processing where technically feasible.

CODAA does not use personal audio content to train or improve AI models by default.

If a future feature requires data to be transferred to a server or an external AI provider, CODAA will update the relevant processing disclosures and meet applicable notice and consent requirements before deployment.

9. Information Sharing and Disclosure

CODAA does not sell users’ personal data.

Data may be shared with or processed by third parties in the following circumstances:
