Privacy policy
What Cyber CTF stores about you, why, and how to have it deleted.
Last updated: October 2026
Cyber CTF is a free platform. We collect as little as possible to run it.
Your account
Accounts are provided by Cyber Auth (cyberauth.co): it stores your email address, name and password hash. Cyber CTF receives an identifier, your name and email when you log in.
Your progress
For each lab we store your evidence submissions: whether they were correct and when. The evidence values you type are compared and never stored.
Cookies
One strictly necessary cookie keeps you logged in (encrypted, httpOnly). A short-lived cookie protects the login flow. We use no advertising or tracking cookies.
Analytics
We use Vercel Web Analytics, which measures page views without cookies and without identifying you.
Your rights
You can ask for a copy or the deletion of your data at any time: hello@cyberctf.org.
