Hidden Systems is a static website. It sets no cookies of its own, runs no advertising, and uses no analytics or tracking scripts. It does not ask for, collect, or store any personal information about readers.
Hosting
The site is served by Cloudflare Pages. Like any web host, Cloudflare processes standard request data (IP address, user agent, requested URL) to deliver pages and protect against abuse. SeeCloudflare's privacy policy.
Fonts
Typefaces are loaded from Google Fonts, which receives your IP address when the font files are requested. SeeGoogle's privacy policy.
Comments
Article and topic pages embed giscus, which stores comments as GitHub Discussions. Posting a comment requires signing in to GitHub and is governed by GitHub's terms and privacy policy. Reading a page loads the giscus widget from giscus.app.

The community feedback space at feedback.hiddensystems.orgruns on Fider, and the support link points to Ko-fi. Both are separate services with their own privacy policies; visiting them is subject to those.
If you email contact@hiddensystems.org, that message and your address are retained only as long as needed to respond and keep a record of any factual correction. They are not added to a mailing list or shared.
