Privacy
Plain language about what this site does and does not collect. Last updated 17 August 2026. Questions: panoutruleout@gmail.com.
What this site is
Scientia is a POL study handbook. It shows basics and formulas in chemistry, biology, physics, astronomy, earth science, electrical engineering, and mathematics in Korean and English. There is no visitor login, member profile, checkout, or comment box.
No accounts
You can read every public page without creating an account. We do not take visitor passwords, and we do not store study progress or bookmarks on a server.
What stays on your device (theme)
Light/dark theme is stored only in your browser under the localStorage key scientia-theme. Clearing site data removes it. That value is not sent to a server.
Hosting logs
Pages are static files on Cloudflare Pages. As with most websites, hosting and security layers may briefly log technical details such as IP address, browser type, and the path requested. That helps keep the site reliable and reduce abuse. We do not build a membership list from those logs.
Cookies and Google ads
This site may use Google AdSense to help keep the handbook free to read. Google and ad partners can use cookies or similar technology under their own policies. Ads do not rewrite formulas or constant tables.
You can limit ad personalization in Google Ad Settings where available: https://www.google.com/settings/ads
Children
Scientia is a general-audience study handbook. We do not knowingly collect personal information from children for accounts, because we do not offer visitor accounts. It can be used in school study, but it is a companion to textbooks, not a child-directed social service.
