MathBrain.lk is a maths-practice app used by students across Sri Lanka, many of them under 16, so we keep it minors-safe. We collect only what we need to sign you in and personalise your practice: your grade, study language, maths exam, attempts and bookmarks. No ads, no ad-tracking and no third-party trackers. You can export your data or delete your account at any time from Settings.
