Is there anything to buy after I download RadRush?

No. RadRush is a one-time purchase — no subscriptions, no in-app purchases, no ads.

No. RadRush runs entirely offline — the question bank and every microgame are bundled with the app.

Yes. Tap the EXTRA TIME button on the main menu to double every round's timer. Everything else about the game stays the same.

Yes. Tap TOPICS from the main menu to pick specific domains, categories, or subcategories across X-Ray, MRI, CT, and Mammography content.

RadRush does not collect, store, or transmit any personal data.

No account or sign-in of any kind.
No internet connection is used during gameplay — there is nothing to send data to.
No analytics, tracking, or third-party SDKs of any kind.
Your high score, RadCoins, and topic preferences are saved only on your own device, and are never transmitted anywhere.
Deleting the app permanently removes all locally saved data.

If this policy ever changes, this page will be updated and the date below will reflect it.
