This page explains which data are nevertheless produced and what happens to them.

Hosting and server log files
The website is hosted by STRATO AG, Otto-Ostrowski-Straße 7, 10249 Berlin. When you open a page, your browser necessarily transmits data to the server for technical reasons: your IP address, the date and time, the address requested, the amount of data transferred, the page previously visited, and your browser and operating system. STRATO processes these data in server log files in order to deliver the website and ensure its secure operation, and deletes them after a short time. The legal basis is Art. 6 (1) (f) DSGVO (GDPR, General Data Protection Regulation); my legitimate interest is a stable and secure website. A data processing agreement pursuant to Art. 28 GDPR is in place with STRATO.
All pages are transmitted in encrypted form (HTTPS).
Visitor statistics without cookies
So that I can see which pages are read, the website counts its own page views, without any third-party service and without cookies. For each day, it counts the pages viewed, the number of views and, if you came here via a link on another website, that website’s name (for example “google.de”). So that nobody is counted twice on the same day, a checksum is formed from the IP address and the browser identifier together with a random value that is newly generated every day. The IP address itself is not stored. The random value is discarded the next day; after that, the checksum can no longer be attributed to anyone, and only the figures remain. The legal basis is Art. 6 (1) (f) GDPR; my legitimate interest is to know how the website is used.
Basket and audio excerpts
Whatever you put in the basket is remembered by your browser in its local storage, so that the basket is kept as you move between pages. Likewise, until you close the window, it remembers which audio excerpt is currently playing. This information does not leave your device; the contents of the basket are only transmitted when you send an order. They disappear when you empty the basket or delete the website data in your browser. The legal basis is § 25 (2) no. 2 TDDDG (German Telecommunications Digital Services Data Protection Act): the storage is necessary so that the basket and the player work as you expect.
Contact form and e-mail
If you write to me via the form or by e-mail, I process your name, your e-mail address and your message in order to reply to you. Messages from the form are stored on the web space and delivered to me by e-mail. To protect against misuse, the website keeps count for one hour of how often messages are sent from a single connection; for this purpose a checksum of the IP address is formed, and the address itself is not stored. The legal basis is Art. 6 (1) (b) GDPR if your enquiry is aimed at a contract (such as lessons or a concert), otherwise Art. 6 (1) (f) GDPR, because I wish to answer enquiries. I delete messages that have been dealt with after one year at the latest, unless I am required to keep them.
CD orders
For an order I need your name, your address, your e-mail address and the CDs ordered: in order to send the CDs, issue the invoice and confirm the order to you by e-mail (Art. 6 (1) (b) GDPR). Your address is on the parcel, so the delivery company (usually Deutsche Post) receives it as well. When you pay, I learn your name and your bank details through my bank. I keep orders and invoices for as long as tax and commercial law require, currently eight years for invoices (§ 147 AO (German Fiscal Code), § 14b UStG (German VAT Act); Art. 6 (1) (c) GDPR).
Videos from YouTube
Some pages show videos from YouTube, a service of Google Ireland Limited, Gordon House, Barrow Street, Dublin 4, Ireland. At first you see only a still image, which is stored on this website itself; no connection to YouTube is made. Only when you click on the video is it loaded via youtube-nocookie.com. Google then receives, among other things, your IP address and the information as to which video you are playing on this website, may use cookies or similar technologies, and may also transfer data to the USA; Google LLC is certified under the EU-US Data Privacy Framework. The legal basis is your consent given by clicking (Art. 6 (1) (a) GDPR, § 25 (1) TDDDG). What Google does with the data is described in Google’s privacy policy.
Links to other websites
Links to other websites (for example to Facebook or to publishers) are ordinary links: only when you follow one do you reach the other website, and its privacy provisions apply there.
Your rights
You have the right to information about the data I have stored about you (Art. 15 GDPR), and to rectification (Art. 16), erasure (Art. 17), restriction of processing (Art. 18) and data portability (Art. 20). You may object to processing based on my legitimate interest (Art. 21 GDPR). You may withdraw consent at any time with effect for the future. An e-mail to me is sufficient.
You can also lodge a complaint with a data protection supervisory authority, for example the one responsible for me: Landesbeauftragte für Datenschutz und Informationsfreiheit Nordrhein-Westfalen (the North Rhine-Westphalia Commissioner for Data Protection and Freedom of Information), Kavalleriestraße 2–4, 40213 Düsseldorf, www.ldi.nrw.de.
