Cookie Policy

Strictly necessary session cookie

bs_refresh keeps you signed in after you log in. It is written by the server, it is HttpOnly so the game's JavaScript cannot read it, it is limited by SameSite=Lax, and in production it requires a secure connection. Its default lifetime is 30 days. Signing out clears it from the browser. Blocking this cookie means signing in again every time your session expires.

Device preferences

astera.language holds the language you picked, astera.music the sound setting, and astera.quality the graphics level. Guide progress, which panels are open, the last commander or world you looked at, season notifications and crash reports recorded on the device may also be kept in browser storage. You can clear these from your browser settings; clearing them does not delete your game account from the server.

Analytics and advertising

Where Google Analytics is configured, it may use measurement cookies such as _ga. When Google advertising is enabled, Google or other advertising providers may use cookies and similar technologies for ad serving, measurement and personalisation. Durations and providers vary with Google's settings and with a visitor's choices, so a fixed list of advertising cookies would not be accurate here.

No storage that could identify you is used before you choose. One exception, named because it is real: Google's ad loader sets a short-lived test_cookie on doubleclick.net to check whether your browser accepts cookies at all. It carries no identifier, expires after about 15 minutes, and is not used to recognise you or to personalise advertising. Google Consent Mode starts with ad_storage, ad_user_data, ad_personalization and analytics_storage all set to denied, and they are only updated after an explicit choice. In the European Economic Area, the United Kingdom and Switzerland that choice is collected by Google's certified consent message; elsewhere, including Türkiye, the game asks with its own privacy notice. You can reopen the choice at any time from Privacy & cookie settings in the game menu.

You can also manage personalised advertising through Google My Ad Center, and delete or block cookies from your browser settings. For more detail see the Privacy Policy and Google advertising technologies.
