After the placement test, using the App requires a paid subscription. Several plans are offered (for example monthly, quarterly and yearly). The price, the billing period and what is included are shown in the App before you confirm, in your local currency and including the taxes that apply.
Payment is handled by Apple (App Store) or Google (Google Play) and charged to your store account when you confirm the purchase. We never see your payment details.
Your subscription renews automatically at the end of each period, at the then-current price, unless you cancel it at least 24 hours before the period ends. You can manage or cancel it at any time in your App Store or Google Play account settings. Cancelling stops the next renewal: you keep access until the end of the period already paid.
If you move to a longer plan, the change takes effect immediately and the store credits the unused part of your current period. If we change our prices, we will tell you in advance, and the store will ask for your consent where the law requires it.
