2. Website hosting and server logs

When you access this website, technical data may be processed automatically in order to deliver the requested pages and keep the service secure and reliable. This may include your IP address, the date and time of access, the requested URL, referrer information, browser and operating-system information, and the response status.

The website is operated using OpenAI’s Sites service and Cloudflare infrastructure. These hosting and infrastructure providers may process technical data on our behalf. The legal basis is Article 6(1)(f) GDPR. Our legitimate interests are the secure, stable and efficient operation of the website.

Log data is retained only for as long as required for delivery, security, troubleshooting and compliance with legal obligations. It may be retained for longer where this is necessary to investigate a security incident or establish, exercise or defend legal claims.

3. Bookmarks and local storage

If you use the “Save article” feature, the selected article identifiers are stored locally in your browser under the-bitcoin-signal:bookmarks:v1. This information remains on your device and is not transmitted to us. The storage is necessary to provide the bookmarking function you request. You can remove individual bookmarks on the website or delete them through your browser settings.

4. Market data and external sources

Bitcoin market data displayed on this website is retrieved by our server from external data sources, including Bitstamp. Your browser does not contact these market-data providers merely because the data is displayed on our pages.

Articles may contain links to third-party websites. If you follow an external link, the relevant third party receives the technical information required to serve its website and processes data under its own privacy policy. We do not control those third-party websites.

5. Cookies, analytics and advertising

This website currently does not use advertising cookies, third-party analytics, tracking pixels or profiling technologies. No non-essential cookies are set for public visitors. If this changes, this policy will be updated and consent will be obtained where required.

6. Recipients and international transfers

Technical data may be disclosed to hosting and infrastructure service providers where this is necessary to operate and secure the website. Depending on the provider and its infrastructure, data may be processed outside the European Economic Area. Where required, such transfers are protected by an adequacy decision or appropriate safeguards under Articles 44–49 GDPR, such as the European Commission’s standard contractual clauses.

7. Your rights

Subject to the applicable legal requirements, you have the right to request access to and rectification or erasure of your personal data, restriction of processing, data portability, and to object to processing based on legitimate interests. You may also lodge a complaint with a data-protection supervisory authority. The competent authority for private-sector controllers in Bavaria is the Bavarian State Office for Data Protection Supervision.
