Cookie Notice
Effective date: July 24, 2026 · Last updated: July 24, 2026
This Notice explains how Lantern uses cookies and similar technologies (local storage and session tokens) on the Service. It supplements our Privacy Policy.
1. What we use today
| Category | Purpose | Examples | Can you disable it? |
|---|---|---|---|
| Strictly necessary | Sign-in and session management (magic-link and passkey sessions), security, and fraud/abuse prevention. | Session and authentication cookies. | No — sign-in cannot function without them. You can clear them in your browser, which signs you out. |
| Functional | Remembering non-essential preferences on your device. | Theme choice (light/dark) in local storage (lantern-theme). | Yes, via your browser’s site-data settings. |
| Analytics | Privacy-respecting, aggregate usage and performance measurement (Vercel Analytics and Speed Insights). These are cookieless — they do not set cookies or track you across sites, and we see aggregate patterns, not profiles. | Cookieless beacons. | Content blockers typically block them; the Service works fine either way. |
| Advertising | Not used. We do not use advertising cookies, and we never use health-related data for advertising of any kind. | — | Not applicable. |
2. Your controls
- Browser settings: every major browser lets you block or delete cookies and site data. Blocking strictly necessary cookies will break sign-in.
- Global Privacy Control (GPC): where the law gives you an opt-out of sale, sharing, or targeted advertising, we honor GPC signals. (We do not sell data or use targeted advertising, so there is nothing to opt out of — the signal is respected regardless.)
- Do Not Track: we do not respond to legacy DNT headers, which lack a settled standard; GPC is the supported signal.
3. Changes
If our use of cookies changes materially, we will update this Notice and its “Last updated” date, and provide any notice or consent mechanism the law requires.
