Privacy Policy

Who is responsible for your data

The controller is Marian Romanienko, the developer of MusicOS™. For anything about privacy, write to kontakt@estateos.pl or call +48 733 344 955. Please put “MusicOS” in the subject line.

Your library stays with you

Your library (titles, artists, albums, artwork), playlists, favourites, listening stats, lyrics and offline copies are stored on your device. We run no server and no accounts — none of it ever reaches us.

Passwords and tokens for your music servers are kept in the iOS Keychain on your iPhone.

Sync through your iCloud

So that your iPad, Mac and Apple TV on the same Apple ID see what your iPhone sees, MusicOS™ stores your list of sources (addresses and user names), My Stations, favourites, lyric timing fixes and the date your trial began in your private iCloud.

Source passwords go to a private CloudKit database in an end-to-end encrypted field — only your Apple ID can read them, not Apple and not us. To stop syncing, turn off iCloud for MusicOS™ in Settings.

Connections to your sources

MusicOS™ connects directly to the places you add, with nothing in between:

• files on your device, iCloud Drive and folders from the Files app (including Google Drive, Dropbox, OneDrive, USB drives and SMB) — only the folder you choose,
• WebDAV and NAS servers, Navidrome / Subsonic, Jellyfin / Emby — the address, user name and password go only to your server,
• Plex — your sign-in goes only to plex.tv to obtain a token,
• DLNA servers on your home network and the station and M3U / PLS addresses you enter.

Public services

A few features use open catalogues. Only the data listed below is sent, with no identifier of any kind:

• lyrics — LRCLIB (lrclib.net) receives the title, artist, album and length of the track,
• artwork and details — Apple’s iTunes Search catalogue receives the title and artist,
• radio — radio-browser.info receives the code of the country you pick; stations play straight from the broadcasters’ servers.

Microphone, photos and local network

• The microphone is used only when you tap the song recognition button. Apple ShazamKit turns the sound into a digital signature; no audio is recorded or stored.
• You pick a photo for a playlist cover in the standard system window — the app receives only that one photo.
• Local network access is used only to reach your NAS, music server or DLNA device.

Your music, your rights

MusicOS™ neither sells nor provides music. It plays only the files and streams you have access to, and you are responsible for using them lawfully.

Purchases

Payments are handled entirely by Apple through the App Store. We never see your card number or billing details — the app only learns from Apple whether a purchase is active. MusicOS™ keeps the date your 7-day free trial began in your iCloud Keychain, so reinstalling does not start it again.

No ads, no tracking

MusicOS™ contains no ads, no analytics and no third-party tracking code. We do not track you across other apps or websites and we never sell data. That is why the App Store lists the app as “Data Not Collected”.

When you contact us

The only data that reaches us is a message you choose to send, together with your email address or phone number. We use it solely to reply (Art. 6(1)(b) and (f) GDPR) and keep it only as long as the matter and any related claims require.

Apple services

Features built on iCloud, the App Store and other Apple services are governed by Apple’s terms, including where Apple processes data outside the European Economic Area under standard contractual clauses. Details: apple.com/legal/privacy.

Your rights

You have the right to access, correct, delete, restrict and port your data, to object, and to withdraw consent. You may also lodge a complaint with the Polish data protection authority (UODO, ul. Stawki 2, 00-193 Warsaw, uodo.gov.pl) or the authority where you live.

You can delete all MusicOS™ data yourself: remove a source, clear offline copies in Settings → Storage, or delete the app. To remove its iCloud data, go to Settings → your name → iCloud → Manage Storage.

Children

The app is not directed at children under 13 and does not knowingly collect their data.

Changes

If we change this policy, the new version will appear at this address with a new date. We will tell you about significant changes in the app.
