Current storage inventory
em_session
Essential, first-party, HttpOnly server session. Used for authentication, eligibility and CSRF binding. Expires after the configured session period.
em_consent_v1
Essential local storage. Records the consent-policy version, optional category choices and saved time until cleared or replaced.
em_house_mode
Essential preference local storage. Keeps the guest Frequency Lens choice on the current device until cleared.
Google OAuth handshake
Essential, short-lived server record only when sign-in begins. Holds digested state, PKCE verifier, nonce and safe return path, then is consumed.
Optional analytics
No analytics cookie or GA4 tag is active in this local build. If the runtime later enables GA4, the strict/basic consent posture prevents the Google script and route events from loading until Analytics consent. The policy and inventory must be updated with the actual provider cookies before activation.
Optional marketing
No marketing technology is installed. The category exists so the control surface does not silently broaden if a separately approved integration is added later. Approval, updated disclosure and consent would be required first.
Change or withdraw
Use the separate Cookie Preference Centre at any time. Withdrawing a category stops future optional use; it does not erase essential account, security or ledger records.
