Privacy
What this site does and does not collect: Google Analytics 4 for aggregate traffic, no advertising, and two small local items that never leave your device.
The short version: this site does not profile you and runs no advertising. It uses Google Analytics 4 to count visits in aggregate (see Analytics below). There is no advertising network, no social embed and no other third-party script.
What the site stores on your device
Two small things, both in your browser’s localStorage and neither ever transmitted. Your colour-theme choice, under the key musics-theme, holds either light or dark. The search box’s recent picks, under the key musics.recent, hold the titles and addresses of the last five pages you opened from search. The page reads them to apply your preference and to offer those pages again. Clearing site data removes both, and nothing breaks if they are absent.
The site sets no cookies of its own. No session identifier, no tracking pixel, no fingerprinting script. Google Analytics sets two optional cookies, described in the cookies page.
Analytics
Google Analytics 4 (Google LLC) receives the pages you view, your approximate location from the IP address, device and browser type, the referrer, and a random identifier stored in its cookies. We use it only for aggregate traffic reports and do not combine it with anything else. You can block it in your browser or with Google’s opt-out add-on.
What the server sees
Like every website, the server that hosts the site records requests in an access log: IP address, time, the URL requested, the referrer if your browser sends one, and your browser’s user-agent string. These logs are controlled and rotated by the hosting provider, are used for security and capacity purposes, and are not combined with anything else or used to build a profile. The site code itself neither reads nor stores them.
Microphone and audio
The chromatic tuner asks for microphone access when you start it. The audio is analysed inside the page with the Web Audio API to estimate the fundamental frequency of the note you are playing. It is never recorded, never uploaded, and stops the moment you stop the tuner or leave the page. Every other tool synthesises sound locally and needs no permission at all.
External links
Articles and the catalogue link to other sites — streaming platforms, reference works, scores. Those sites have their own privacy practices and will see the request once you follow a link. Nothing is loaded from them while you are reading here: no embedded players, no preview widgets, no tracking parameters beyond the ones the platforms themselves attach to their own release links.
Your rights
Apart from the pseudonymous analytics identifier above, no personal data is collected by this site, so there is little to export, rectify or erase. If you believe a host-level log contains something it should not, or you want to ask about a specific request, use contact.
The legal basis for the server logging described above, where the GDPR applies, is legitimate interest in operating a secure website. No data is sold, shared or transferred to third parties for marketing.
