Lumen Notes
Cookie Policy
Effective date: June 12, 2026
Short version: only essential cookies are set — the ones required for the site and app to function. We use cookieless, privacy-preserving analytics (Vercel Web Analytics): no cookies, no cross-site tracking, no ad networks, and no identifier that follows you across sites. Optional cookie-based tools would load only after you consent through the banner, and as of the effective date above, we use none. Declining changes nothing about how the site works.
Essential cookies and storage we use
| Name | Type | Purpose | Lifetime |
|---|---|---|---|
| Session / auth cookies (lumen.1labs.app) | Cookie | Keeping you signed in to the Lumen app securely. | Session, or up to 30 days with "remember me" |
| lumen-cookie-consent | localStorage | Remembering your accept/decline choice so the banner doesn't reappear. | Until you clear browser storage |
| lumen-promo-founding50-dismissed | localStorage | Remembering that you dismissed the Founding Clinician announcement bar. | Until you clear browser storage |
| lumen-exit-prompt-shown | localStorage | Ensuring the one-time offer reminder is never shown again. | Until you clear browser storage |
Analytics — cookieless by design
We use Vercel Web Analytics to understand aggregate page traffic. It is cookieless and privacy-preserving: it sets no cookies, stores nothing on your device, performs no cross-site tracking, and shares nothing with ad networks. Because it uses no cookies or persistent identifiers, it operates independently of the consent banner, which governs optional cookie-based tools only.
Optional cookies
None today. If we ever add cookie-based tools to the marketing site, they will load only after you choose "Allow optional cookies" in the banner, this page will be updated first, and your earlier "essential only" choice will continue to be honored.
Third-party cookies
Our marketing pages set no third-party cookies. When you check out, Polar (our merchant of record) sets the cookies needed to process payment on its own domain, under Polar's privacy policy.
Managing cookies
You can change your choice anytime by clearing this site's data in your browser — the banner will reappear. Blocking essential cookies in your browser will prevent sign-in to the app.
