Getting Started

What is Cube IQ?
Cube IQ is a calm, focused app for training your brain through trivia, flashcards, and daily study. You can explore dozens of topics, test yourself with quiz challenges, review with spaced repetition, and even create your own custom flashcard decks to study anything you like.

How do I start studying?
From the Home screen, tap Practice to review flashcards at your own pace, or Challenge to test yourself with multiple-choice questions. Set a daily goal to build a steady study habit and keep your streak alive.

What is spaced repetition?
Spaced repetition is a proven study method that shows you cards at the right moment just before you'd forget them so information sticks in your long-term memory with less effort. Cube IQ handles the scheduling for you automatically.

Custom Decks

How do I create my own flashcards?
Head to the Topics screen and choose to create a custom deck. Give your deck a name, then add your own questions and answers. Your custom decks are perfect for studying anything whether it is a new language, medical or legal terms, exam material, class notes, or any subject you're learning.

How do I delete a custom deck?
Open the custom deck from the Topics screen and use the delete option on the deck's detail page. This permanently removes the deck and all of its cards, so please delete with care.

Are custom decks part of Cube IQ Premium?
Creating unlimited custom decks is a Cube IQ Premium feature. See the subscription section below for details.

Cube IQ Premium & Subscriptions

What does Cube IQ Premium include?
Cube IQ Premium unlocks unlimited daily cards, unlimited custom decks, Challenge Mode across every topic, and an ad-free experience.

How much does it cost?
Pricing is shown in the app on the upgrade screen and may vary by region. You'll always see the exact price and billing period before you confirm any purchase.

How do subscriptions work?
Cube IQ Premium is an auto-renewing subscription. Payment is charged to your Apple ID at confirmation of purchase, and your subscription renews automatically unless you cancel at least 24 hours before the end of the current period.

How do I cancel my subscription?
Subscriptions are managed through your Apple ID, not inside the app. To cancel, open your device's Settings, tap your name, tap Subscriptions, select Cube IQ, and choose Cancel Subscription. You'll keep Premium access until the end of your current billing period.

How do I restore a purchase?
If you've reinstalled the app or switched devices, open Settings in Cube IQ and tap Restore Purchases. Your Premium access will be restored using your Apple ID.

How do I get a refund?
All purchases are handled by Apple, so refunds are requested through Apple rather than through us. Visit reportaproblem.apple.com, sign in with your Apple ID, find your Cube IQ purchase, and follow the steps to request a refund.

Your Data & Privacy

Where is my data stored?
Your progress, streaks, ranks, and custom decks are stored locally on your device. Cube IQ is designed to work without an account.

Will I lose my progress if I delete the app?
Deleting the app removes its local data, including your custom decks and study history. Please be aware of this before uninstalling.

How do I reset my data?
The app includes a reset option in Settings that clears your study progress, streaks, and ranks. This action is permanent and cannot be undone.

Where can I read your Privacy Policy and Terms?
Our full Privacy Policy and Terms & Conditions are available on this site and within the app.

Troubleshooting

The app isn't working as expected.
First, try closing and reopening the app. If the issue continues, make sure you're running the latest version from the App Store and that your device software is up to date. If problems persist, email us with a description of what's happening and your device model, and we'll help you sort it out.

My purchase isn't showing up.
Open Settings in the app and tap Restore Purchases. If your Premium access still doesn't appear, make sure you're signed in with the same Apple ID used for the original purchase, then contact us if you still need help.

A card looks incorrect.
We work hard to keep our content accurate. If you spot something that looks wrong, please email us the topic and the question so we can review and fix it.

Still Need Help?

We'd love to hear from you whether it's a question, a bug, a content correction, or a feature idea.
