Contact support
Email support@mjdapps.com with your device model and a short description of the issue.
How do I restore Gold Version?
Open Settings and tap Restore Purchases while signed in with the Apple Account that made the purchase.
Where are my decks and battles stored?
Decks, battle history, favorites, tags, and preferences remain on your device.
Does analysis need an internet connection?
No. Building, importing, organization, history, and analysis work offline. Videos and external links need a connection.
Why did opening a deck leave the app?
Deck links open Clash Royale. Video playback connects to YouTube, and purchase links open Apple services.
Is Clash Decks available on Android?
The Android version is being prepared for Google Play. Until its store listing is live, download links on this site lead only to Apple’s App Store.
