Contact us
Questions, problems, purchases, refunds: email [email protected]. Please mention your device (iPhone or Android) and, if you can, the app version from Settings → About.
Restore a purchase
If you bought Shikken before — on another device, or before reinstalling the app — use the same Apple ID or Google account and tap Restore on the purchase screen, or open Settings → Purchases → Restore purchase. There is no Shikken account: your purchase is tied to your Apple ID or Google account.
Cancel a subscription
Subscriptions are managed by Apple or Google, not by us, so we cannot cancel them for you. Deleting the app does not cancel a subscription.
- iPhone / iPad: Settings → your name → Subscriptions → Shikken → Cancel Subscription.
- Android: Google Play → profile icon → Payments & subscriptions → Subscriptions → Shikken → Cancel subscription.
In the app, Settings → Purchases → Manage subscription opens the same page.
Refunds are handled by the store too: on iOS at reportaproblem.apple.com, on Android through Google Play.
Report an error in a card
If a meaning, reading, example or audio looks wrong, tap Report an error on the card. The app opens your email app with a pre-filled message (the word, its card number, the deck version and the app version) — add what is wrong and press Send. Nothing is sent until you do. Without an email app, write to [email protected] with the word.
