Privacy Policy

MathsUnlockedBN (“we”, “the app”) is a free maths practice app for secondary-school students in Brunei, available at mathsunlockedbn.vercel.app. This page explains, in plain language, what information the app keeps and who can see it.

What we keep

• Your account: a display name you choose, and either a 6-digit PIN or your Google sign-in. If you use Google, Google gives us your email address so we can recognise you when you come back.
• Your school (optional), if you choose one.
• Your progress: answers, grades, streaks, XP and level, achievements, daily challenge and Mock Exam results, and your profile choices (icon, card background, and so on).
• Feedback you send from the app, and any replies to it.
• Homework you do for a class: your answers and score and, if your teacher turns it on for that class, the written working you draw on the sketch pad.
• Notes your teacher keeps about you if you join a class: for example session goals, a short summary of a tutoring session, and corrections to your rank.
• When you were last active, used to show “online now” to your friends.
• If you turn on notifications: a token from your browser that lets us send you reminders. You can turn this off at any time in Settings.

We don’t ask students for a real name, address, phone number, or date of birth, and there is no advertising or tracking by advertisers in the app.

Parent phone numbers. A teacher may save a parent or guardian’s phone number against a student so they can send that parent the student’s session or monthly summary on WhatsApp. The number is entered by the teacher, not the student. Only that teacher (and the app’s administrator, for support) can see it. The app never sends a message by itself: when the teacher taps the button, WhatsApp opens on the teacher’s own phone or computer with the message ready, and WhatsApp’s own terms apply from there. Teachers are responsible for having the parent’s agreement to be contacted.

Who can see what

• Other players can see your display name, school, level, achievements, card style, and rankings on the leaderboards. Friends can also see when you were last online. Your email address is never shown to other players.
• Your teacher, if you join a class, can see your progress, grades, homework results and any working you recorded in that class, and can see whether you have notifications turned on.
• Your parent or guardian can see your progress if you share your Parent Link with them.
• The app’s administrator can view accounts and feedback in order to run the app, give support (for example resetting a forgotten PIN), and keep it safe.

Who processes the data for us

• Supabase stores accounts and progress.
• Vercel hosts the website.
• Google, only if you choose “Continue with Google”, to confirm who you are. We only ask for your basic profile (name and email).
• Your browser’s push service, only if you turn on notifications.

We don’t sell your information or share it with advertisers.

Cookies and storage

The app doesn’t use advertising or tracking cookies. It keeps your login and settings in your browser’s own storage on your device so you stay signed in, and (if you tick “remember me”) so the login screen can be filled in for you. Logging out, or clearing your browser’s site data, removes it.

To understand how many people visit the site and how many make an account, we count visits to the landing and sign-up pages using a random number stored in your browser (not your name, PIN, email or IP address), the website you came from and your country (a two-letter code such as BN). It is not used for advertising and is never linked to your account.

Students

The app is meant for secondary-school students. We recommend students use it with the knowledge of a parent, guardian or teacher. Please don’t put personal details you wouldn’t want others to see into your display name or feedback.

Keeping and deleting your data

We keep your account and progress while you use the app. You can delete your account yourself at any time in Settings → Account → Delete account. This removes your login, progress, friendships, leaderboard results, class memberships, messages and everything else linked to you straight away, and it can’t be undone. (If you are a teacher, it also removes your classes, homework and saved parent numbers.) If you can’t sign in, email the address below and we’ll delete it for you. Teachers can remove students from their class at any time.

Changes

If this policy changes in a way that matters, we’ll update the date above and, where appropriate, tell players inside the app.
