Privacy notice: what this site records about visitors, and what not

The pages are plain, static documents. They do not ask for an account, a name or an email address, and there are no forms that submit personal data. Nothing on the site places a cookie in your browser, whether for preferences, advertising or measurement.

There is no analytics software of any kind. No page-view counter, heat map, session recorder or advertising tag runs on the site, and no social media buttons or embedded videos report your visit to another company. Because no third-party scripts are loaded, no outside service learns which pages you read here.

The reason is simple. A reference about discontinued electronics kits has no need to know who its readers are, how long they stay or where they came from. Collecting that kind of data would add risk for visitors and bring nothing useful to the pages, so the site leaves it out entirely.

Fonts are served from the same server as the pages rather than from an external font service, so loading the text does not send your address to anyone else. Images and style sheets are served from the same server as well.

Like almost every web server, the server that hosts this site writes a line to an access log for each request it receives. A typical entry contains:

• the IP address the request came from;
• the date and time of the request;
• the page or file that was requested, and whether it was delivered;
• the user agent string your browser sends, which names the browser and operating system.

These logs exist for security and for keeping the site running: spotting attacks, blocking abusive traffic and finding broken links. They are not used to build profiles of visitors, not combined with other data, and not sold or shared for marketing. They are retained for a limited time and then deleted in the normal course of log rotation.

If you write to [email protected], the message and the address it came from are the only personal data involved. The message has one purpose: checking the correction or suggestion it contains against the available sources. It is not added to a mailing list, not used for marketing and not passed to third parties.

Messages are not answered individually, as the contact page explains, so there is no ongoing correspondence to store.

Some pages link to outside sources, such as manufacturer datasheets on analog.com, the OWFS project, the Linux kernel documentation or the Home Assistant documentation. Following such a link takes you to a site with its own privacy practices, which this notice does not cover. No information about you is passed along when you click, apart from what your browser normally sends to any site it visits. Outbound links are limited to manufacturers, established open-source projects and software vendors, and the link text names the site or document it leads to, so it is clear before clicking where a link goes.

If the way the site handles data ever changes, for example if a new feature needs a cookie, this page will be updated before the change takes effect, and the description above will say exactly what is new. For how the site's text and illustrations are made, see the AI notice and the about page.
