1. Overview

Tunathic is a guitar and music utility application providing tools such as a guitar tuner, metronome, BPM tap tool, chord library, scale library, interactive fretboard, music theory references, and a repertoire of song sheets you write yourself.

The current version of Tunathic does not require an account and does not operate a developer-controlled backend service.

2. Microphone Access

Tunathic requires microphone access for the Guitar Tuner.

Microphone input is used to analyze audio locally on your device and estimate musical pitch.

Microphone audio used by the tuner:

• is processed locally on your device;
• is not uploaded to Tunathic servers;
• is not stored as an audio recording;
• is not shared with third parties; and
• is not used for advertising or tracking.

Microphone access is requested only when functionality requiring the microphone is used.

You may revoke microphone permission at any time through your device settings. The Guitar Tuner will not function without microphone access, while other features of the application can continue to be used.

3. Information Stored on Your Device

Tunathic may store application preferences locally on your device, such as interface or tool settings.

Tunathic also stores your Music Theory progress locally: which lessons you have starred as favourites and which you have opened most recently. This is kept only to bring you back to what you were reading.

Tunathic also stores the songs you add to the Repertoire, including their lyrics, chords, and transposition settings, locally on your device. This content is created or entered by you. Tunathic provides no song catalog and no import, export, or sharing feature.

This information is used to preserve your preferences, your songs, and your reading position between sessions, and is not transmitted to Tunathic servers. You can delete a song at any time in the app, and clearing the application's storage or uninstalling the application removes all of it.

4. Data Collection and Sharing

The current version of Tunathic does not intentionally collect or transmit personal information to the developer.

Tunathic currently does not include:

• user accounts;
• analytics services;
• advertising services;
• crash-reporting services;
• cloud synchronization; or
• developer-operated remote storage of user data.

Tunathic does not sell personal information.

5. Internet and Network Services

The current production version of Tunathic does not require an Internet connection for its core functionality and does not intentionally transmit application usage or microphone data to Tunathic servers.

6. Third-Party Services

The current version of Tunathic does not integrate third-party advertising or analytics services.

Third-party services may be introduced in future versions of the application. If a future version changes how user information is collected, processed, shared, or transmitted, this Privacy Policy will be updated before or alongside that change, as applicable.

Any relevant disclosures and consent mechanisms required by applicable law or platform policies will also be implemented where necessary.

7. Advertising

Tunathic does not currently display advertisements and does not currently use Google AdMob or another advertising network.

Advertising may be introduced in a future version of Tunathic. If advertising is introduced, this Privacy Policy will be updated to describe the advertising services used and their data practices before or alongside the applicable release.

Where required, appropriate consent and privacy controls will be provided.

8. Children's Privacy

Tunathic is a general-purpose guitar, music practice, and music theory utility and is not specifically designed or directed toward children.

The application does not knowingly collect personal information from children through developer-operated services.

If the application's audience, services, or data practices change, this section will be reviewed accordingly.

9. Data Security

Because the current version does not intentionally transmit personal information or microphone recordings to Tunathic servers, such information is not stored in developer-operated remote systems.

Information stored locally by the application remains subject to the security protections provided by the user's device and operating system.

10. Artificial Intelligence

Tunathic contains no artificial intelligence or machine learning feature that processes your data. No user content — songs, lyrics, chords, transposition settings, preferences, or microphone audio — is sent to an artificial intelligence service, and none of it is used to train an artificial intelligence model.

Pitch detection in the Guitar Tuner is a deterministic signal-processing algorithm that runs locally on your device. It is not a remote artificial intelligence service and requires no Internet connection.

Development disclosure: parts of Tunathic's source code were written with the assistance of artificial intelligence coding tools (OpenAI Codex and Anthropic Claude). These tools are used only during development, on the developer's own systems, and have no access to user data, to your device, or to the application at runtime. Code produced with their assistance is reviewed by the developer before release.

If a future version of Tunathic introduces a feature that transmits user data to an artificial intelligence service, this Privacy Policy will be updated before or alongside that release.

11. Changes to This Privacy Policy

This Privacy Policy may be updated as Tunathic evolves.

Changes may be necessary when new features, third-party services, advertising, analytics, online services, or other data-processing functionality are introduced.

The effective date at the top of this page will be updated when material changes are made.
