Are there any in-app purchases or subscriptions?
No. You pay once and every deck is included, along with every future word update. There are no ads.
Tilting doesn't work. What can I do?
Hold the phone sideways (landscape) on your forehead with the screen facing out, then nod it clearly down or up and bring it back to level before the next card. You can also tap the right side of the screen for "Got it" and the left side for "Pass".
The round didn't start by itself.
The countdown starts once the phone is held upright on your forehead for a moment. You can always tap "Tap to start" instead.
Is it OK for kids?
Yes. All words are family-friendly. The Little Kids deck always shows big pictures, and you can turn on Picture Mode for any other deck so younger kids who can't read yet can play too.
How long is a round?
Choose 30 seconds, 1 minute, 1½ minutes or 2 minutes before you start.
Can I use it in my classroom?
Yes! The Classroom decks (School Day, U.S. History, Math & Shapes) work great for review games and indoor recess.
There's no sound.
Head Bonk! follows your phone's silent switch. Turn off silent mode and check that Sound is on in Settings (gear icon).
Will cards repeat?
Cards don't repeat until you've seen every card in that deck. To start fresh, open Settings and tap "Reset best scores & card history".

Head Bonk! (“the App”) is provided by an independent developer (“we”). This policy explains how the App handles information.
We do not collect any personal information. The App has no accounts, no sign-in, no ads, no analytics and no tracking, and it does not connect to the internet.
Motion sensor
During a round, the App reads your device's motion sensor to tell when you tilt the phone down (got it) or up (pass). These readings are used instantly on your device and are never stored or sent anywhere.
Scores and settings
Your best scores, settings and the list of cards already shown are stored only on your device. They are never sent to us or to any third party.
Purchase
The App is purchased through the App Store. Apple processes the payment, and we do not receive your name, email address or payment information. Please see
Apple’s Privacy Policy for details.
The App is a family party game that may be played by children. Because we do not collect, store or share any personal information from anyone, including children under 13, no personal information is collected under the Children’s Online Privacy Protection Act (COPPA).
You can clear best scores and card history at any time from Settings → “Reset best scores & card history”. Deleting the App removes all data stored on the device.
We may update this policy when the App changes. Updates will be posted on this page with a new “Last updated” date.
