Privacy

The short version: you can use FLC without an account and without telling us who you are. Many of our learners are minors, so we try to collect as little as possible.

Learning progress

Lesson completion, quiz scores, saved lessons, achievements, your Daily Challenge streak, and your sound setting are stored in your browser's local storage on your own device. This information is not sent to FLC unless you make a save code or join a class (see below). You can erase it anytime from the My progress page or by clearing your browser data.

Save codes

If you choose to make a save code, FLC stores a copy of your progress under that code so you can pick it up on another device: lessons finished and when, quiz scores, saved lessons, calculators tried, and your Daily Challenge streak. A save code has no name, email, or password attached, and we don't ask who you are. Anyone who has the code can see and add to that progress, so keep it private.

You can delete the saved copy anytime from the My progress page, and the code stops working. A saved copy that goes unused for 400 days is deleted automatically.

Certificate verification

After earning the FLC Certificate, you can choose to create a verification link. FLC then stores the name you typed for the certificate (or no name, if you left it blank), the date you earned it, and your final quiz score in each course, under a certificate ID printed on the certificate. Anyone with the ID or link can see that record, so a college or employer can confirm FLC issued it. Verification pages are kept out of search engines.

You can delete the record anytime from the certificate page on the device that made it, and the link stops working. Records you don't delete are kept so the certificate stays verifiable.

Teacher accounts

Teachers can create a free account with their email address. We use it only to email sign-in codes — there are no passwords. Signing in sets a cookie that keeps the teacher signed in for up to 30 days; it's used only for signing in.

Classes

A teacher can create a class and share its code. To join, a student types the code and a name — we ask for a first name and last initial, like “Maya R.” Students don't give an email or password; instead they get a student code for signing in on other devices.

While a student is signed in to a class, FLC stores their name, student code, and progress in that class: lessons finished and when, knowledge check and final quiz scores, and which page they're on and when they were last active. Only the teacher who owns the class can see it. Signing out of a class removes that progress from the device; it stays saved with the class.

Teachers can remove a student, give a student a new code, delete a class, or delete their account at any time, and that data is deleted. Accounts, classes, and student progress that go unused for 400 days are deleted automatically.

Live quiz games

To join a live quiz game, a player types a nickname (we ask players not to use their real full name, and inappropriate nicknames are blocked). The game stores that nickname, the player's answers, and their score so the teacher's screen can show a leaderboard. The teacher can remove any player. Everything about a game is deleted automatically about 3 hours after it was last used.

Forms

The teacher and chapter forms ask for a name, a school email address, and details about a class or school. We use this only to follow up with the person who submitted it. The forms are meant for teachers and faculty sponsors, and they ask people not to include student information.

Submissions are emailed to the FLC club inbox using Resend, an email delivery service. To count sign-ups, the site also keeps the school name, city, and state (and, for teachers, subject and grade level) — but not names or email addresses. Submissions are kept only as long as they're useful for following up, and we'll delete yours if you ask.

Analytics

FLC uses Vercel Web Analytics, which is cookieless, to count page views and see general traffic (like which pages are popular and which countries visitors come from). The site also counts a few anonymous learning milestones — a course started, a lesson completed, a final quiz taken, a course or certificate completed, a calculator used — as simple totals. These counts include no names, emails, account IDs, or anything that identifies a person.

Children's privacy

Students never need an account, email address, or password to use FLC, and their progress stays on their own device unless they make a save code (which holds no name or contact details) or join a teacher's class. In a class, students share only a first name and last initial, and only their teacher can see it. A certificate verification record includes a name only if the student chooses to add one, and they can delete it anytime. Live quiz games use nicknames. Teacher accounts and our forms are for adults, and our forms ask them not to include student information. Teachers should use classes only as their school's student privacy policies allow. If you believe a child has sent us personal information, email us and we'll delete it.
