This Privacy Policy explains what information is collected when you visit bacher-ai.com, how it is used, and what rights you have as a visitor. The short version: this site sets no tracking cookies, runs no analytics software, displays no advertisements, and does not share any information with third parties for commercial purposes.
This policy is written in accordance with the Swiss Federal Act on Data Protection (revDSG, in force since 1 September 2023) and, where applicable to visitors from the European Economic Area, with the General Data Protection Regulation (GDPR, Regulation EU 2016/679).
Who operates this site
bacher-ai.com is a personal website and blog covering artificial intelligence, digital privacy, and related topics. It is operated as a private, non-commercial project based in Switzerland. It is not a registered business and does not collect or process personal data for commercial gain. For enquiries regarding this policy, use the Contact page.
What data is collected and why
This site does not use analytics software, advertising networks, social media pixels, or any third-party tracking tools. Visitor behaviour is not monitored, profiled, or recorded at the application level. No personal data is collected through forms, comment fields, or subscriptions — these features are not active on this site.
The only data processing that occurs is at the infrastructure level, as is standard for any server connected to the internet:
- Server access logs — the web server automatically records each request in a standard access log. This includes the requesting IP address, the URL requested, the HTTP status code, the referring URL if present, and a timestamp. These logs exist solely for operational and security purposes — diagnosing server errors and identifying malicious or abusive traffic. They are retained for a maximum of 7 days and are then automatically deleted, unless retention beyond that period is required for the investigation of a specific incident. They are not used to analyse visitor behaviour and are not shared with any third party.
- WordPress session cookie — WordPress sets a temporary
wordpress_test_cookieduring the login process only, to verify that cookies function correctly in the browser. This cookie is not stored persistently and contains no personal data. - WordPress authentication cookies — when a user logs in to this site, WordPress sets standard authentication cookies (
wordpress_[hash]andwordpress_logged_in_[hash]) to maintain the session. These are strictly functional cookies required for the authenticated session to operate. They are only set for users who actively log in and are not set for any visitor who does not have an account or does not log in.
Fonts and locally hosted assets
This site uses the typefaces Rubik and Karla. These fonts are served directly from this server — they are not loaded from Google Fonts or any other external font service. No font request is made to any third-party server when you visit this site, and no IP address or browser data is transmitted to Google or any font provider.
Hosting and infrastructure
This site is hosted on the infrastructure of CCC Rheintal (Meierenaustrasse 32, 9443 Widnau SG, Switzerland). The server is located in Switzerland. The hosting provider processes IP addresses in server access logs as part of routine server operation, in accordance with their own privacy policy. As confirmed by the hosting provider’s policy, server log data is deleted after a maximum of 7 days. No application-level data from this site is shared with the hosting provider beyond what is inherent to the server infrastructure.
Third-party services
This site does not embed content from third-party platforms (such as YouTube, Twitter/X, or Instagram) that would cause your browser to make requests to those platforms. Images used on this site are either self-hosted or sourced from Pexels under a free licence and served locally. No external service receives your IP address or any other data as a result of visiting this site.
Cookies
This site sets no cookies for visitors who are not logged in. Authentication cookies are only set when a user actively logs in to the site — a feature intended for registered users in the future. Visitors browsing the site without an account or without logging in will not have any cookies set in their browser. As a result, no cookie consent banner is required or displayed — under both Swiss revDSG and EU ePrivacy rules, a consent mechanism is only required where cookies that are not strictly necessary for the service are set for general visitors. None are.
Legal basis for processing (revDSG / GDPR)
The only personal data processed — IP addresses in server access logs — is processed on the basis of legitimate interest (Art. 6(1)(f) GDPR; Art. 31 revDSG): specifically, the operational necessity of running a web server and the security interest in being able to identify and respond to malicious traffic. This processing is proportionate, limited in duration (7-day retention), and does not override the interests or rights of visitors given the minimal nature of the data and its non-commercial use.
Your rights
Under the Swiss revDSG and, where applicable, the GDPR, you have the right to request access to any personal data held about you, to request its correction or deletion, and to object to its processing. In practice, the only data that could relate to you is a server log entry containing your IP address, which is deleted automatically within 7 days. You may submit a request via the Contact page. You also have the right to lodge a complaint with the Swiss Federal Data Protection and Information Commissioner (FDPIC) at www.edoeb.admin.ch, or, if you are located in the EU, with your national data protection authority.
Changes to this policy
This policy will be updated if the data processing practices of this site change materially — for example, if analytics, a contact form, or a newsletter subscription are introduced. The date at the top of this page always reflects when the policy was last revised. Continued use of the site after a change constitutes acceptance of the revised policy.
