Privacy

Spark Nexus authenticates you with the AT Protocol (for example, a Bluesky handle). We store your DID, handle, self-attested birthdate (for mature-content gating), role, Spark balance, card collection, decks, trades, friends, and game results on our servers.

Card art you upload is stored on our server and, when possible, published as a blob on your own Personal Data Server. Profile display name, avatar, and bio live on your AT Protocol profile — when you edit them here we write to your PDS; we do not keep a separate canonical copy. Avatar bytes may be proxied briefly so your profile can render before public AppViews index your account.

We do not sell personal data. Session cookies are used only to keep you signed in. In-app notifications stay on our database; we do not email you unless that changes and we update this page.

You can stop using the service at any time. Contact the site operator to request deletion of your local account data.
