The short version

This is a static web app. It does not have a user database or a server that stores anything about you. There are no accounts, no first-party cookies, no analytics, no fingerprinting and no tracking pixels set by this site. The player starts from its defaults each visit and audio is processed entirely in your own browser.

What is stored on your device

Nothing personal. The player does not write settings, presets or listening history to storage. The only client-side storage is the service-worker cache of the app's own files, which lets the page load fast and start offline.
Dark/light theme is a session-only CSS class: it resets when you close the tab and is never sent anywhere.

Clearing site data removes the service-worker cache. There is nothing else to erase.

What leaves your browser

Only the requests needed for the feature you actively use:

The stream you play — your browser connects directly to the radio station you choose (or to the station's HLS/CDN host). That host necessarily sees your IP address, as with any HTTP request; we do not proxy or log it.
Optional AI ad-muting — only when you enable the toggle: your browser downloads models/commercial-detector.onnx (101 KB), its config.json and calibration.json from this site, plus the ONNX Runtime Web build (onnxruntime-web@1.22.0, WebAssembly) from cdn.jsdelivr.net. Log-mel features are computed locally from the stream tap; audio samples and features are never uploaded, stored or transmitted. Disable the toggle and no further requests occur.
Anonymous advertising — one A-ads frame is loaded from acceptable.a-ads.com in a sandboxed iframe. It is third-party content: we set no cookies on it and it cannot read our page, but the ad network may set its own cookies under its own policy.
Hosting — this site is served by Codeberg Pages from Berlin, Germany (EU), which processes standard server logs (IP address, user agent) to deliver the page.

Legal basis and your rights (GDPR)

We do not process personal data ourselves, so we have no user records to hand over, correct or delete. Where server logs exist at our host, the legal basis is our legitimate interest in operating the site (Art. 6(1)(f) GDPR). You have the right to access, rectification, erasure, restriction, portability and objection (Art. 15–21 GDPR), and to lodge a complaint with your local supervisory authority. Since nothing is stored on your device beyond a cache of the app's own files, clearing site data is the complete erasure.

Commercial radio and processing

Audio-processing disclaimer: the enhancer (automatic gain staging, adaptive three-band expansion, parallel harmonic excitation, auto-volume, optional tape saturation and valve drive) changes the signal you listen to; some rights holders' terms restrict altering or re-broadcasting their streams. Only process what you are allowed to process, and check each source's terms. This is not legal advice.

AI ad-muting: privacy and legal position

The AI ad-mute is an optional listening aid, not an advertising system. It runs entirely on your device, classifies 3-second windows of the stream you already chose, and attenuates the output gain. No audio, transcript, fingerprint or listening history leaves your browser; the model was trained on public Internet Archive radio material, never on user data, and contains no personal information. It is off by default and can be overridden at any time with FORCE UNMUTE.

Legal position: the classifier is probabilistic — on our held-out evaluation it caught 97% of ad clips at 90% precision, so a false mute is possible. Muting happens locally to audio you are already allowed to play; it does not record, store, redistribute or re-broadcast anything, does not circumvent access controls, and does not affect the anonymous ad unit that funds this site. It does not change your licensing obligations, does not authorise public or commercial playback you would otherwise need a licence for, and some broadcasters' terms restrict altering their stream — check them. This is not legal advice.

Business and venue use

This player is intended for personal, private listening. Playing radio or licensed music in a business (café, bar, restaurant, shop, gym, office) generally requires a licence or permit from your local collecting society — for example Buma/Stemra in the Netherlands, SABAM/PlayRight in Belgium and GEMA in Germany — and unlicensed public performance can lead to fines. Businesses should use the High Fidelity Pure Business edition, which is built around royalty-free music, and should still verify the licence of every source they play. This is not legal advice.

Children

The player is not directed at children and collects no data from anyone, including children.

Changes

If this policy changes, the date at the top changes with it. Because there is no account or mailing list, we cannot notify you individually.
