The sizeof.cat website is hosted and served statically from an Exoscale cloud instance in Switzerland, is not logging any data, is not using any scripts/applications for tracking its visitors, does not place any cookies on your computer.

Logging

I disabled access and error logs in nginx so there is absolutely no trace of any of the visitors of this site. I suggest you do the same thing if you can. The side effect is that I have no idea how many visitors the website gets but let’s say I’m rounding the number down to one million daily. j/k

access_log off;
error_log /dev/null;

Data Transfer

All data is served over the HTTPS protocol , encrypting all data between the browser and the server. Your network provider will still be able to see that you are downloading data from sizeof.cat, but they will not be able to see the content.

Do Not Track

This site uses the LetsEncrypt Certificate Authority , which is itself DNT-compliant and does not log your browser checking the validity of this site’s HTTPS certificate. The DNT policy file is available here .

HTTP referer

This website is using meta tags to strip referer information (yes, that’s how the HTTP header IS spelled) from all outgoing links as well as placing rel="noreferrer" on the same anchor links, therefore not passing any referral data from this site to any external websites.

<meta name="referrer" content="never" />
<meta name="referrer" content="no-referrer" />

Webmentions

When you send a webmention to this site, you are explicitly providing metadata in your site’s markup, and this information is used to display your comment/reply on this site. This information consists of:

  • Your name or username.
  • A profile picture or avatar, if you have set one on your site.
  • The url of your site, and the specific url of your comment/reply.
  • The content of your comment/reply.

All of this is information made public by you, and no information other than information you have made public can be captured by this process.
