Your Privacy is Pivotal
We protect passwords
Your password is hashed using Bcrypt and a per user salt, then stored in a protected external server. This way, we don’t see (or have any knowledge of) your password. This server is managed by an information security partner, which uses Cloudflare to protect against numerous potential attacks.
We don’t sell your information
Our mission is to provide free, relevant math materials to teachers and students - not to make money from your information. We do not sell your information to third parties for profit.
We avoid reaching out to students
Intrigued students sometimes make accounts on our site. We try to avoid contacting students, unless they first reach out to us with questions or they apply/enroll in a sponsored student program.
