Privacy policy
This is a translation for convenience. Only the German version is legally binding.
In short: This website sets no cookies, uses no advertising services and embeds no third-party content. We serve fonts and images ourselves. We measure how often the pages are viewed with our own tool, without cookies and without storing your IP address (section 3). Beyond that, only the technical data needed to deliver the page is processed, plus whatever you send us yourself through the contact form.

2. Hosting and delivery
The website is delivered via Cloudflare (Cloudflare, Inc., 101 Townsend St., San Francisco, CA 94107, USA). When you open the page, Cloudflare processes technically necessary connection data: IP address, date and time, requested address, browser identifier (user agent) and amount of data transferred. This is needed to deliver the page and protect it against attacks.
From the IP address, Cloudflare also determines the country you are visiting from. We use it to send you to the matching language version (German, French or English) when you open the homepage. The country is not stored for this redirect; it is included in our audience measurement as the country of origin (section 3).
The legal basis is Art. 6 (1) (f) GDPR; our legitimate interest lies in providing the website securely and reliably. Cloudflare processes the data on our behalf under a data processing agreement. A transfer to the USA is possible; Cloudflare is certified under the EU-US Data Privacy Framework (Art. 45 GDPR). We do not analyse this connection data and have not enabled any logging at Cloudflare; our own audience measurement is described in section 3.
3. No cookies, audience measurement without cookies
We set no cookies and use no advertising pixels, social media plugins or third-party analytics services. The website stores nothing in your browser's local storage; the language versions are separate pages. We serve the fonts together with the website ourselves; there is no connection to Google or other font providers.
We measure how our website is used with a tool we run ourselves (Spurlos Analytics). It sets no cookies and stores nothing on your device.
With every page view, your browser transmits: the page viewed and its title, the page you came from (referrer), screen size, browser language, time zone and technical details of your browser (user agent). Clicks on external links (e.g. the donation platforms), phone numbers, email addresses or downloads are counted as well. Sending the contact form is not recorded. For each of these events we store the page on which it happened and, for links, the link target.
Your IP address is not stored. To link page views from the same visit, we create a hash value from the IP address, the user agent and a secret random number. The random number is generated anew every day and the old one is deleted; after that, the hash value can no longer be traced back to you. As origin we store only the country that Cloudflare determines from the IP address, not the city.
We store the time of page views and clicks only to the full hour. The exact time of the most recent request is used solely to tell where a visit ends (a visit ends after 30 minutes without a request) and is deleted afterwards; only the length of the visit remains.
Only aggregated information is stored (page, referrer, browser, device type, country, language), no profiles. The data is kept in a Cloudflare database located in the EU and is not passed on to third parties. Cloudflare runs the tool for us as a processor (see section 2).
The legal basis is our legitimate interest in designing the website to meet visitors' needs (Art. 6 (1) (f) GDPR). There is no access to your device within the meaning of Section 25 of the German TDDDG, as no information is stored on it or read from it beyond what is technically necessary to deliver the page.
You can switch off the measurement in your browser: with the “Do Not Track” setting or with a content blocker.
4. Visits by search engines and AI services
When an automated program (for example a search engine crawler or AI services such as ChatGPT, Claude or Perplexity) retrieves our pages, we log, based on the program's identifier (user agent), the name of the program, the page retrieved, the time, the response status and the country the request comes from. We do not store IP addresses. We delete individual requests after 90 days; after that, only daily totals per program and page remain. The legal basis is Art. 6 (1) (f) GDPR (interest in our content being findable in search engines and AI services).
5. Links to donation platforms and other sites
We link to GoFundMe, Ulule, Spotify, BNN and scientific publishers. Only when you click a link do you move to that provider's site; from then on, its privacy policy applies. Donations and orders are handled exclusively through these platforms. We only receive the information the platform makes available to campaign organisers (e.g. name and amount, unless you donate anonymously).
6. Contact by email and contact form
If you write to us, we use your details only to answer your message. The legal basis is Art. 6 (1) (f) GDPR, and Art. 6 (1) (b) GDPR for enquiries about working together. We delete the message once it has been dealt with, unless retention obligations apply.
When you use the contact form, we process your name, your email address, the topic you chose and your message. The website forwards these details via Cloudflare (see section 2, “Email Service”) as an email to our mailbox so that we can reply to you directly. Nothing is stored on the website itself.
7. Your rights
You have the right of access (Art. 15 GDPR), rectification (Art. 16), erasure (Art. 17), restriction of processing (Art. 18), data portability (Art. 20) and to object to processing based on Art. 6 (1) (f) GDPR (Art. 21). An informal email to us is sufficient.
You can also lodge a complaint with a data protection supervisory authority, for example the State Commissioner for Data Protection and Freedom of Information of Baden-Württemberg.
