Privacy
Your deck data stays on your device.
No account, no developer-operated analytics, and no advertising tracking.
Last updated: August 11, 2026
This policy explains how MJD Apps handles information when you use Clash Decks, visit this website, or contact support.
Information stored on your device
Saved decks, deck names, favorites, tags, archive status, battle results, opponent archetypes, private notes, preferences, and Gold entitlement status are stored locally. They are used to provide app features and are not uploaded to a developer-operated account or server.
Information we do not collect
The app does not ask for your name, address, phone number, location, contacts, photos, microphone, advertising identifier, or payment-card details. We do not sell personal information, build advertising profiles, or use developer-operated analytics or tracking SDKs.
Customer support
If you email support, we receive your email address and the information you choose to include. We use it to respond, troubleshoot, prevent abuse, and keep an appropriate support record. Do not send sensitive information that is not needed for your request.
YouTube and external services
Video thumbnails and embedded playback connect directly to YouTube. Google or YouTube may receive network, device, request, and interaction information under their own policies. Deck links can open Clash Royale or Supercell pages, and App Store links can open Apple services.
Gold Version purchases
Apple processes StoreKit purchases, payment methods, purchase history, refunds, revocations, and restoration. MJD Apps does not receive your payment-card details. The app receives only the transaction and entitlement information needed to determine whether Gold should be active.
Website information
The website has no account registration, advertising trackers, or forms. Its hosting provider may process ordinary server-log information such as IP address, requested page, browser type, and request time to deliver and protect the site.
Retention, deletion, and security
Local information remains until you delete records, reset relevant data, or remove the app. Device backups may retain data according to your settings. The app relies on iOS and iPadOS security protections, but no storage or transmission method is completely secure.
Children, choices, and changes
Clash Decks does not knowingly collect children’s personal information through a developer-operated service. You can manage local records in the app and control backups in device settings. We may update this policy when the app, law, or third-party services change.
Android and Google Play
The Android version stores decks, battle history, preferences, and entitlement state on the device. Google Play may process download, device, diagnostic, and account information under Google’s own policies. The Android release does not currently offer Gold purchases.
