Privacy & Saves

Your Progress

The Campaign, Risk and Planet X save in this browser. Clearing site data removes those local copies. Export a backup in the game. Signing in enables private Firebase cloud copies, with explicit choices when devices disagree. Cloud restore replaces this browser’s current game only after you confirm; an automatic local recovery copy is retained.

Your Account

Firebase Authentication manages sign-in. Your saves are readable only by your account. Other players cannot browse them. The Big Leagues stores authoritative league state on the server and shares only permitted views with league members. Its offline mode keeps views and unsubmitted plans, and needs a connection to commit decisions.

A Quiet Corner

No advertising, analytics or third-party tracking is included. Firebase processes authentication, hosting and game data. Cached game assets help return visits stay fast; your browser may evict cached data when storage is low.

Moving From Data

Open Data’s former Arcade address, export the migration file, then choose Bring Saves From Data in the Games Room. Browsers separate storage by origin, so the new domain cannot read the old app’s saves directly. The original copies remain in Data’s browser storage.
