Things to know first
- 01
The pass is digital content that opens the moment you pay, so once you begin using it the right of withdrawal may be limited. We say this again on the screen before payment.
- 02
Payment and refunds are handled by Apple on the App Store and by Google on Google Play — each store's own process applies.
- 03
When the 30 days end you simply return to the free plan — nothing is charged again. To continue, just buy another pass.
- 04
Studying in the app stays free — ads cover the cost. Nobody should be unable to prepare for the exam because of money.
