Privacy Policy

Last updated: September 2026

Overview

Muzik 2007 (“the App”) is published by Sundai. The App is available for Mac and iPhone (Apple App Store), for Windows (Microsoft Store and direct download) and for Android (Google Play and direct download). This policy covers all of them.

Data collection

We do not collect any personal data. There is no account, no sign-in, no analytics, no crash reporting, no advertising identifiers and no third-party SDK that collects data. We do not operate any server that your music or your listening passes through.

Your library — the audio files, the artwork, the playlists, the play counts and every setting — stays on the devices you installed the App on.

What the App accesses

• Your music files. On Windows the App watches the folders you point it at; it reads them and never copies, moves, renames or writes into them. On Mac, iPhone and Android it reads the library folder it owns.
• Your local network (Windows and Android). See “Syncing” below.
• Your iCloud account (Mac and iPhone only). Used solely to sync your library between your own Apple devices. That data lives in your personal iCloud account, is governed by Apple’s privacy policy, and is not accessible to us.
• Device battery level (iPhone and Android). Shown in the player’s status bar. It is never transmitted.

Syncing

Windows ↔ Android sync happens entirely on your local network. The Windows app runs a small web server that only accepts connections from private (LAN) addresses; your phone pairs with it using a six-digit code you read off the PC screen, and then pulls the library over Wi-Fi. Nothing is uploaded to us or to any third party, and no connection leaves your network. This is what the privateNetworkClientServer capability on the Microsoft Store listing is for.

Mac ↔ iPhone sync happens through your own iCloud account, as described above.

Network connections the App makes

The App contacts the internet only in these cases, all of them optional or user-initiated:

• Album metadata lookup. When you ask the App to fill in missing artist, album, year or artwork, it sends the song’s search text (title and artist) to Apple’s public iTunes Search API (itunes.apple.com) and uses the result. No identifier of you or your device is sent. You can decline the lookup and tag your files by hand.
• The mp3 downloader (direct-download Windows build only). When you paste a link and press import, the bundled yt-dlp and FFmpeg contact that site directly from your machine to fetch the audio and convert it to an mp3 on your disk. Nothing about the link, the download or the resulting file is sent to us or to anyone else. Before downloading, the app may also run a search on the same site to find the official album upload of the same track and prefer it. This feature is not present in the Microsoft Store build, which ships without it and without yt-dlp and FFmpeg, nor in the Mac App Store or iOS App Store builds, where the code is compiled out.
• Links you click. Opening a link in the About screen hands it to your browser.

Children’s privacy

The App does not collect data from anyone, including children under 13.

Changes to this policy

We may update this policy from time to time. Changes will be posted on this page, with the date above updated.
