Privacy Policy

Effective May 14, 2026. HarmonyKeen is built to keep your music work close to you: on your device, under your control.

Overview

HarmonyKeen is a local-first desktop app for creating harmonies from melodies you provide. The current app does not require an account, does not include HarmonyKeen cloud sync, and does not automatically upload your music projects to HarmonyKeen servers.

What Stays on Your Device

The app works with the musical material you choose to use, such as imported MIDI files, HarmonyKeen project files, generated harmony ideas, autosaves, and app preferences. This information is stored locally on your device to support app functionality.

Files You Choose

HarmonyKeen imports files only when you choose to open or import them. It exports files only when you choose to save, export, download, or drag them out of the app. Once you export a file, it is managed by your device and by any other service you choose to use.

Crash and Error Reporting

HarmonyKeen is not built around advertising, analytics, or session replay. Basic crash reporting may be added later only to help improve reliability, and this policy will be updated if that happens.

What We Do Not Collect

HarmonyKeen does not sell your data. The current app does not require account registration, does not use advertising tracking, does not use product analytics, and does not access your microphone, camera, precise location, contacts, calendar, health data, or financial data.

Data Sharing

HarmonyKeen does not automatically share your MIDI files or HarmonyKeen project files with HarmonyKeen servers. If you export a file, upload it somewhere, send it to someone, or open a third-party link, that action is controlled by you and by the service you choose to use.

Your Choices

  • You choose which music files to open or import.
  • You choose when and where to save or export files.
  • You can delete exported files wherever you saved them.
  • You can remove local app data through app or operating system controls where available.

Website and Third-Party Links

This website does not use analytics, account systems, tracking cookies, or other tracking tools. HarmonyKeen may include links to third-party websites for credits, licenses, support, or documentation. Their privacy practices are their own.

Updates and Contact

This policy may be updated as HarmonyKeen changes. Questions about HarmonyKeen privacy can be sent to [email protected].
