Questions about Premium
How does the free trial work?
The annual plan starts with 7 free days. You get a reminder 2 days before the trial ends, and you can cancel before then without paying.
What happens if I stop paying?
You keep everything you made and everything you studied. Premium extras such as sync and extended decks stop, and the free plan carries on.
Why is there a lifetime option?
Many people prefer to pay once. Lifetime gives you Premium for as long as the app exists, with the same fair-use limit on AI cards.
Do prices differ by country?
Yes. In the app stores, prices follow each store’s local price tiers. On the web they are shown in your currency at checkout.
