Understand what stays in your browser.
A practical guide to authentication storage, preferences, the installed app and optional analytics.

Necessary authentication storage
Firebase uses browser storage to maintain authentication sessions. Consent choices are saved in trade_diary_cookie_consent. Signing out changes authentication state; clearing browser storage can remove access to a guest identity.
Preferences and PWA assets
trade_diary_theme remembers Light, Dark or System. Form settings and drafts may be saved by journal features. The installed-app service worker stores safe static assets and its offline screen, never private API or Firestore responses.
Optional analytics
Microsoft Clarity analytics cookies, including _clck and _clsk, are optional. Analytics is off until consent is given and is restricted to public pages. You can change consent using the preferences control below. Withdrawing consent stops tracking; previously created cookies may also be removed through your browser settings.
