Data controller: Arcana Mentor.
The local core
Arcana stores the tracker, catalog, deterministic recommendations and history on your computer. You do not need an account to use the free core or factual overlay.
What it reads
The application may read the detailed logs Arena writes on your computer to detect drafts, matches and public cards. It does not read memory, intercept traffic or automate actions.
What leaves your computer
The local core does not automatically upload logs, deck names, cards, opponent identifiers or screenshots. Remote features activate only after you sign in, have the corresponding entitlement and allow remote explanations in Settings. A remote query sends only the minimum necessary context; the service stores quota metadata and a cached response to avoid duplicates, with limited operational retention.
Accounts and payments
An account is only needed to activate Arcana Plus. Secure checkout is hosted by Stripe; Arcana does not receive or store your full card number. Plus is offered at €5.99 monthly or €49.99 annually; you can manage or cancel the subscription through the Stripe portal. Checkout shows the price and applicable terms before you confirm any charge.
Control and deletion
From Settings, you can export your data without tokens and request deletion of account data and associated remote content. To fully remove the local core, uninstall Arcana or delete its data folder after using the deletion option. Do not share credentials or full logs with third parties.
