Privacy Policy

App “tunewell” · Last updated: October 2026

The app contains no ads, no analytics and no tracking, and it doesn’t create an account. It communicates with a server of mine (api.bumberger.at, hosted by World4You in Austria) only for searching with Claude.

Data on your device

The app stores your favorites, settings, the last station you listened to, recently chosen countries and the alarm and sleep timer settings on your device. The “Played” list (artist, title, artwork address, station and time of recently played songs, up to 500) stays on your device only and is neither synced nor transmitted.

Sync via iCloud

If you are signed in to iCloud, the app syncs your favorites and some settings (country for suggestions, appearance, station list behavior, autoplay) between your devices through your private iCloud area. I have no access to them. Apple’s privacy policy governs what data Apple processes as part of iCloud.

Station directory (Radio Browser)

The station list, suggestions by country and the search by station name come from the free, community-run directory Radio Browser. For this, the app sends your search text or the chosen country to its servers. When you start a station, the app also reports its identifier there so that popular stations rank higher. No information about you personally is transmitted; as with any connection, the server sees your IP address. Radio Browser’s own information applies to its processing.

Radio stations

The app fetches the audio directly from the server of the respective station, as well as the station logo and the title information the station sends. The station or its streaming provider sees your IP address and the type of your device and may log this; the station’s privacy information applies. I have no influence on this and receive nothing from it.

Artwork and titles (Apple)

For the song that’s playing, the app looks up the album artwork and the correct spelling in Apple’s catalog (iTunes Search). For this, it sends the artist and title as the station sends them, and your device’s country, to Apple. No information about you personally is transmitted.

Song recognition (Shazam)

With Premium, the app identifies songs on stations that send no title, on demand or automatically. For this, it loads a few seconds of the station over a separate connection, computes a signature from it on your device and sends only that signature to Apple’s Shazam service, which returns the matching song. The microphone is not used. Apple’s privacy policy applies to the processing at Apple.

Search with Claude

With Premium you can describe what you want to hear. Only after you have agreed to searching with Claude once does the app send your search text, the app language, your device’s country and a random identifier of your app installation (not linked to your name, Apple ID or email address) over an encrypted connection (HTTPS) to my server. The server forwards the search text, country and language to the Anthropic (Claude) API and returns the suggested search terms to the app; the app then looks up the stations itself on Radio Browser. I do not store search texts or answers and don’t write them to any log.

To limit usage, the server counts searches per calendar month and installation identifier and logs the time, the number of tokens processed and the response time of each search – without the search text – as well as technical error messages. I delete the counters after 13 months and the log after 90 days. As I don’t know you by name, I cannot link these entries to a person. The hosting provider World4You keeps the usual technical access logs (e.g. with the IP address); its privacy policy applies. The legal basis is providing the feature you chose (Art. 6(1)(b) GDPR) and my legitimate interest in preventing abuse and controlling costs (Art. 6(1)(f) GDPR).

Anthropic (Claude)

The searches are processed by Anthropic PBC (USA); data may be transferred to the USA. How Anthropic processes data is governed by its terms and privacy notices. My server transmits no information about you personally. Please don’t enter personal data such as names or addresses into the search; they are sent to Anthropic with the search text.

Saving songs (Apple Music, Spotify, Tidal)

When you add a song to a playlist, iOS asks once for access to your library. The app then reads the list of your playlists, creates the “tunewell” playlist if needed and adds the song; this happens directly between your device and Apple Music. The links to Apple Music, Spotify and Tidal open their app or website with a search for artist and title; from there, their privacy information applies.

Siri, CarPlay, alarm and AirPlay

Apple processes voice commands through Siri; the app only receives the recognized command, such as the name of the station you asked for. For CarPlay, AirPlay and the Lock Screen, the app passes the station, title and artwork to your device’s system. The app sets the alarm with Apple’s AlarmKit on your device; iOS asks once for permission. No data is sent to me for any of this.

“tunewell Premium” subscription

You buy and manage the subscription through Apple. Apple processes payment data, name and email address; I do not receive them. The app checks on your device whether a subscription is active, using the purchase records signed by Apple; nothing is sent to my server for this.

Android version

This policy also applies to tunewell on Android. Radio Browser, the radio stations, the artwork lookup at Apple and the search with Claude work the same way as described above. The differences:

• Data on your device: The app stores favorites, “Played” and settings only in its own storage; there is no sync like iCloud. If Android backup to your Google account is turned on, Android also backs up this data there so it comes back on a new device; Google’s terms apply.
• Subscription: You buy and manage the subscription through Google Play. Google processes payment data, name and email address; I do not receive them. The app checks on your device via Google Play whether a subscription is active; nothing is sent to my server for this.
• Song recognition (Shazam): The app passes the audio of the station that is playing directly to ShazamKit; a signature is created on your device and sent to Apple’s Shazam service. The microphone is not used. To access ShazamKit, the app fetches a short-lived access token from my server; nothing but the request itself is transmitted, and my server stores nothing about it. As with any request, my hosting provider sees the IP address (see above).
• Chromecast: When you play a station on a Chromecast or a Google Cast speaker, the device receives the stream address, the station name and the logo and fetches the audio from the station itself. Meanwhile, the app reads the titles over a separate, short connection to the station. The connection to the Cast device runs through Google Play services on your device.
• Android Auto, notification and lock screen: The app passes the station, title and artwork to Android and Android Auto. Android asks once for permission to show notifications; without it the radio still plays, just without controls in the notification.
• Saving songs: The links to Spotify, YouTube Music, Apple Music and Tidal open their app or website with a search for artist and title. Apple Music playlists, Siri, CarPlay, AirPlay and the alarm are not available on Android.

No tracking

tunewell contains no ads, no analytics or tracking services and doesn’t create an account.

If you email me, I use your address and message only to answer your request.

Your rights

Under the GDPR you have the right of access, rectification, erasure, restriction of processing and objection, and the right to lodge a complaint with the Austrian Data Protection Authority (dsb.gv.at). You delete favorites, settings and the “Played” list by removing the app; you can also clear “Played” in the app, song by song or all at once. You delete the copy of your favorites and settings in your iCloud area in your device’s iCloud settings. You cancel a subscription in your Apple account settings.
