What MathPrepLab is

MathPrepLab (mathpreplab.com) is an independent, free visual practice lab for Digital SAT Math and AP Calculus AB/BC covering 40 core subtopics (160 interactive problems). Every problem is algebraically verified by our curriculum team and generated from synchronized mathematical parameters. You can use all lessons and practice problems as a guest without creating an account.

What we collect

Google profile information (only if you choose to sign in): When you sign in with Google, Google shares only your email address and display name with us. We never see your Google password or other Google account data.
Practice progress & mastery state: Which questions you answered, whether they were solved correctly, and your study streak. For guests, this is stored only in your browser’s local storage. When you sign in, your progress is also synced to our server so you can pick up on any device.
Usage & diagnostic telemetry: A random visitor ID stored in your browser, which pages and learning tools you interact with (for example, opening the 3-step method, calculator, or reporting an issue), device viewport category (mobile/tablet/desktop), and error diagnostics. When you are signed in, this activity is associated with your account to support progress syncing and site reliability.

We honor your browser’s Do Not Track (DNT) and Global Privacy Control (GPC) signals by disabling analytics telemetry when enabled.

How we use it

To sync your progress, to understand which lessons help students, and to find and fix bugs. We do not sell your data and we do not show ads.

Where it is stored
