Cookies & browser storage
What this website stores on your browser, why it is used and how to control optional analytics.
Your choices
Optional analytics are off by default. Use “Privacy choices” in the footer to allow them or turn them off again. Declining does not prevent browsing, sending an inquiry or signing in. Browser Global Privacy Control and Do Not Track signals also keep optional analytics off.
Your choice applies to this website on this browser. Businesses hosted under separate /s/ addresses have separate choices. We remember a choice for up to 180 days, then analytics stay off until you choose again. Clearing browser storage resets it.
| Storage | Purpose and duration |
|---|---|
| Privacy choice | immersyn-privacy:* in local storage: analytics choice, policy version and time chosen. Effective for 180 days. |
| Requested preferences | immersyn-theme remembers a selected light/dark theme until cleared. immersyn-newsletter-dismissed-at remembers a dismissed signup prompt for seven days; the stored timestamp remains until cleared. |
| Sign-in | Supabase sb-*-auth-token cookies, which may be split into numbered parts, maintain requested account sessions. Cookie lifetime and active session validity are separate; signing out ends the browser session. These are used for authentication, rather than optional analytics. |
| Chat, where available | immersyn:chatbot-session:* in session storage links messages in a chat you request. It remains for the browser tab session. Chat messages and any contact details you submit are also processed on the server. |
| Optional Vercel Web Analytics | Loaded only after analytics permission on Immersyn’s public marketing pages. It uses a server-generated daily hash rather than an analytics cookie. This is separate from how long analytics reports are retained. |
Essential security processing and features you request do not depend on the optional analytics setting. Payment checkout and external sites have their own privacy and storage practices. We do not load advertising pixels or embedded maps in the current website; a directions link opens the map provider when you choose it.
