Privacy policy

Last updated: November 3, 2026

This policy explains what happens to your information when you visit ckptzero.com, the website of Checkpoint Zero (CKPT0), an online community about using AI. We keep it short and plain.

What we collect

If you make an account, we keep your email address, your password (stored scrambled, so nobody, including us, can read it) and the lessons you save. We never ask for payment details here. Accounts are run by Supabase, which stores this information for us on secure servers. We also use an email delivery service to send account emails, so it receives your email address and the message it delivers for us.

If you don't make an account, we don't ask you for your name or email. Two tools collect information automatically:

• Cloudflare Web Analytics counts visits and page views so we know which pages are useful. It doesn't use cookies and doesn't identify you. We only see totals.
• Meta Pixel (from Meta, the company behind Facebook and Instagram) uses cookies to record that your browser visited our pages and whether you clicked a link to join our community. Meta may receive technical details such as your IP address, browser and device type.

Our interactive pages may save your progress (for example, your score in a game) in your own browser. That information stays on your device and isn't sent to us.

How we use it

• To let you log in, save lessons and search your library.
• To send emails about your account, such as confirming your email or resetting your password. We don't add you to a mailing list.
• To understand which pages and lessons people find useful.
• To show ads for Checkpoint Zero on Facebook and Instagram to people who have visited this website, and to measure whether those ads work.

We don't sell your information. Meta handles the data it receives under its own privacy policy.

Your choices

You can turn off the Meta Pixel on this site at any time. If your browser sends a Global Privacy Control signal, we treat it as a "No thanks" automatically.

You can also manage how Meta uses your activity for ads in your Facebook ad preferences, or clear cookies in your browser settings.

Your account

You can change your password from your account page at any time. To delete your account and everything saved in it, email us from the address you signed up with and we'll remove it.

Other websites

Links on this site take you to other services, such as our community on Skool. Those services have their own privacy policies, which apply once you're on their sites.
