What Slipstream keeps in your browser, and how to remove it.
No tracking cookies
Slipstream has no advertising or behavioural analytics. It uses necessary browser storage for sign-in, saving and settings, rather than tracking cookies. This page was updated on 9 November 2026.
Local storage for your game
The browser stores a sign-in session, game preferences and temporary unsent progress. Older local careers and recovery points remain until you delete them. Online careers are stored on the server and are not removed by clearing browser storage.
What each entry is for
slipstream-auth holds your sign-in session and a related code-verifier entry supports authentication links. slipstream.clientId identifies this browser for save conflicts. slipstream.cloud.pending.<user>.<slot> buffers unsent careers, slipstream.cloud.importOffered.<user> remembers the old-save import offer, and slipstream.stats.pending.v1 buffers game-statistics submissions. Existing slipstream.save slots and backups, activeSlot, settings, tutorial, unlocked modes, race panel preferences and realStandings cache remain for their original purposes. Pending data is sent to your account service and removed after acknowledgement.
Strictly necessary
This storage exists only to provide the game you asked for. Under UK rules on cookies and similar technologies, storage that is strictly necessary to provide a service you request does not need consent, which is why there is no cookie banner.
Our hosting provider
Cloudflare, which hosts the site, may occasionally set a short-lived security cookie, for example when checking that a visitor is not an automated bot. These cookies are strictly necessary for security and are not used for tracking or advertising.
Your choices
Sign out through the account panel to clear the local sign-in session. Check for unsaved progress before doing so. Browser site-data settings remove local storage but leave acknowledged cloud saves on your account. Delete online slots or your account through the game. Downloaded exports and reports remain on your device until you delete them.
Future changes
Accounts and online saves are active; automatic crash reporting and behavioural analytics are not. If other storage is introduced, this notice will explain its purpose before use. Questions can be sent to contact@slipstream.games.
