This website uses Remark42 comment system. The remark42 is self-hosted by author of this website on Hetzner Cloud in Hetzner Cloud datacenters in Finland. Remark42 collects minimal amount of information necessary to provide comment service: authentication information and comments text, as well as some information necessary for debugging / abuse detection such as IP addresses.

Authentication is provided by 3rd party services. Please consult their privacy policies when choosing to authenticate. Authentication is only required for posting comments, reading comments does not expose your data to any third-party services. Unfortunately the author of this site did not find a way to enable anonymous posting without exposing website to spam and fraudulent posts.

Remark42 is an open-source software, and authors publish following privacy claims:

  • Remark42 is trying to be very sensitive to any private or semi-private information.
  • Authentication requesting the minimal possible scope from authentication providers. All extra information returned by them dropped immediately and not stored in any form.
  • Generally, remark42 keeps user id, username and avatar link only. None of these fields exposed directly - id and name hashed, avatar proxied.
  • There is no tracking of any sort.
  • Login mechanic uses JWT stored in a cookie (httpOnly, secured). The second cookie (XSRF_TOKEN) is a random id preventing CSRF.
  • There is no cross-site login, i.e., user's behaviour can't be analyzed across independent sites running remark42.
  • There are no third-party analytic services involved.
  • User can request all information remark42 knows about and export to gz file.
  • Supported complete cleanup of all information related to user's activity.
  • Cookie lifespan can be restricted to session-only.
  • All potentially sensitive data stored by remark42 hashed and encrypted.


The website itself does not use any cookies. However:

  • Google Analytics stores "_ga" cookie to provide statistics about returning visitors. Owners of the website do not have access to this cookies, and Google Analytics is set up in a way which does not exposes any PII (see above).
  • For authenticated visitors comment system (remark42) stores two cookies: one containing login information, and one random (XSRF_TOKEN) to prevent cross-site scripting. Both cookies are required for correct functionality of the comment system. The cookies are limited to "" subdomain and are not passed to any 3rd parties.
