Privacy,
in plain words.
Who is responsible
This site and the data below are run by H. C., Zurich. For any question about your data, write to [email protected].
Hosting
The site is served by Cloudflare. To deliver pages and protect the site, Cloudflare processes the technical data every visit sends, such as your IP address and browser, under its own privacy policy. Cloudflare is a US company; transfers to the US are covered by its certification under the EU-US and Swiss-US Data Privacy Frameworks. This site does not store that data.
What the site records
To see which pages are read, the site keeps a small record of visits:
- Page views: the time, the page and the country your visit came from.
- Reads: when you stay on a page, scroll or click, the same plus how far you scrolled, how long you stayed, the kind of device (desktop, tablet or phone) and the browser family. To tell visitors apart within one day, a code is made from your IP address and browser with a one way function and a secret. The code changes every day, is never stored in a form that shows your address, and cannot follow you from one day to the next. Where you came from is kept as the search engine or the domain of the site that linked here, never the full address.
- Clicks: when you follow a link that leaves the site or open a prototype, the time, the page, the link and the country.
No IP address and no user agent string is stored. The site sets no cookies for visitors, loads no third party scripts or fonts, and shares nothing with advertisers or analytics companies.
How long
Visit records are kept for up to 120 days, then deleted.
Why
To understand which pages are useful and to improve them. Under the EU General Data Protection Regulation this is a legitimate interest; Swiss data protection law allows the same.
If you write, your message and address are kept to answer you and are not used for anything else.
Your rights
You can ask what is stored about you, and ask for it to be corrected or deleted, at [email protected]. Because visit records hold no name or address, they usually cannot be linked to you. You can also complain to a supervisory authority: in Switzerland the Federal Data Protection and Information Commissioner, in the EU the authority of your country.
