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.
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;
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.
This site opts out of all FLoC cohort calculation by sending the HTTP response header
Permissions-Policy with a specific flag. This enables a site to declare that it does not want to be included in the user’s list of sites for cohort calculation.
add_header Permissions-Policy "interest-cohort=()";
Whether Google respects the flag, now that’s another issue.
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 .
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" />
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.
