Quick answers
I paid but I don’t have Sumo Kanji Pro
Open Settings → Subscription and tap “Restore purchases”, on the same Apple Account you paid with.
How do I cancel Sumo Kanji Pro?
On iPhone and iPad: Settings → your name → Subscriptions. On a Mac: the App Store → your name → Account Settings → Subscriptions. Cancel at least 24 hours before it renews.
How does the free trial work?
The trial opens every notebook for free. Cancel at least 24 hours before it ends and you won’t be charged. With notifications on, we remind you two days before.
I have a new phone, iPad or Mac. Where is my progress?
Your progress lives on the device you learn on, and each device keeps its own - there are no accounts, so nothing about you is stored anywhere else. Sumo Kanji Pro comes with you: tap “Restore purchases” on the new one, signed in with the same Apple Account.
How do I delete my data?
Everything is on this device. Settings → About → Reset progress erases it, and so does deleting the app.
