Questions, feedback, bug reports, or just want to share how your child is getting on — we'd love to hear from you. We aim to respond within 2 business days.
Questions about the app, how it works, what's covered, or how to get the most out of Brain Booster for your child.
✉ hello@bboostapp.comQuestions about how Brain Booster handles your family's data, requests to access or delete your data, or COPPA and GDPR enquiries.
✉ privacy@bboostapp.comFound something that isn't working right, or have an idea for how Brain Booster could be better? We genuinely read and consider every message.
✉ feedback@bboostapp.comYes — completely free to use. All six practice categories, all five grade levels, the parent dashboard, progress tracking, and the reward system are all available at no cost. The app is supported by contextual advertising shown to parents (never to children during practice sessions).
Progress is saved to the cloud via Firebase, so it requires an active internet connection. If you're seeing saving issues, check your connection and try refreshing. If the problem persists, email feedback@bboostapp.com with a description of what's happening and which device you're using.
Yes — the parent dashboard supports multiple child profiles under a single parent account. Each child has their own private profile and their own progress data.
Open app.bboostapp.com in Safari on your iPhone, tap the Share button (the square with an arrow), then tap "Add to Home Screen". Brain Booster will install as a full-screen app without any Safari chrome — just like a native app, with no App Store required.
You have two options:
Option 1 — Self-service (instant): Open the app at app.bboostapp.com, go to the Parent Dashboard, tap Settings, then Storage Panel, then Clear all data. This immediately and permanently deletes all quiz history, child profiles, and progress data from Firestore. Your login account remains active so you can start fresh.
Option 2 — Full account deletion: Email privacy@bboostapp.com with the subject line "Account deletion request" and include the email address associated with your Brain Booster account. We will delete all Firestore data associated with your account and remove your account from Firebase Authentication within 5 business days. You will receive a confirmation email when complete.
Brain Booster covers the CogAT (Cognitive Abilities Test) — Verbal, Quantitative, and Nonverbal batteries — and the SAGES (Screening Assessment for Gifted Elementary and Middle School Students) — Reasoning, Language Arts, and Maths & Science subtests. Content is available for Kindergarten through Grade 8.
