Privacy Policy
Who runs this site
The IE Knowledgebase is a free, open-source collection of courses on industrial engineering, maintained by its contributors and published from the crackcode09/ie-knowledgebase repository. There is no company behind it and nothing is sold here.
What we collect
Nothing that identifies you. The site has:
- no sign-up, login or user accounts;
- no cookies, including no cookie banner because there is nothing to consent to;
- no analytics, advertising, pixels or fingerprinting scripts;
- no forms, comments or newsletter, so there is nothing for you to type and send to us.
We do not see who visits. We cannot link a visit to a person.
Browser storage
The site keeps a small amount of data in your browser's local storage so the page remembers you between visits:
| Key | What it holds |
|---|---|
iekb-done | Which courses you have ticked as done |
iekb-mods | Which modules you have ticked as done |
iekb-theme | Light or dark theme, if you changed it |
iekb-track | Which learning track you picked on the learning path |
iekb-pmode | Whether the learning path follows a track or fits your time |
This data stays on your device. It is never sent to us or to anyone else, and it is not shared between your devices. The reset button in the catalog header clears your course and module progress; clearing site data in your browser removes all of it. The site works without it; if storage is blocked, progress is simply not remembered.
Third-party services
Like almost every website, these pages are delivered by services that process your IP address and standard request details (browser type, page requested, time) in order to serve the files. We do not receive that information from them.
| Service | Used for | Their policy |
|---|---|---|
| Cloudflare Pages | Hosting and delivering the site and the course files | Cloudflare privacy policy |
| cdnjs (Cloudflare) | Loading the D3, marked, DOMPurify, Mermaid and anime.js libraries that draw the map, render and clean the lessons, and animate the page | Cloudflare privacy policy |
| Google Fonts | Loading the Inter, Space Grotesk and JetBrains Mono typefaces | Google Fonts privacy FAQ |
Cloudflare, which hosts and delivers the site, processes visitor IP addresses and may keep them in its logs for security and to keep the service running; those logs belong to Cloudflare and are not available to us. Cloudflare's dashboard shows the site's maintainer aggregate traffic totals (requests, data served, countries) that do not identify anyone. We do not turn on Cloudflare Web Analytics or any other analytics.
If you take part on GitHub
If you open an issue, start a discussion or submit a pull request, you do so on GitHub under your GitHub account and GitHub's own terms. Whatever you post there is public, as is the usual case for an open-source project. We do not collect it separately.
Children
The courses are written for working professionals and students. Because the site collects no personal data, there is nothing to collect from anyone of any age.
Your rights
Privacy laws such as the GDPR and the CCPA give you rights over personal data an organisation holds about you. We hold none, so there is nothing to access, correct, export or delete on our side. For the data in your browser, you are in control: use the reset button or your browser's site-data settings.
Changes to this policy
If the site ever adds anything that would change the picture above, for example analytics or a way to sign in, this page will be updated first and the effective date at the top will change. The full edit history is public in the repository.
