This is a research site. You can read every part of it — the cross-asset study, each market’s page, the straddle simulation, the conditional lookup — without an account and without giving up any personal information. An account is optional and does one thing: sync the lookup views you save across devices.

Without an account

Saved lookups are stored in your browser (localStorage) and never sent to us. The only analytics is Cloudflare Web Analytics: privacy-preserving, cookieless page-view counts with no cross-site tracking and no personal data. There are no advertising cookies, tracking pixels, or other third-party trackers. Our hosts (Vercel, Render) keep short-lived standard request logs — IP address, timestamp, URL path — which rotate automatically.

With an account

Sign-in is a one-time email link (no password). If you create an account we store your email address (used only to sign you in — never sold, never used for marketing) and the lookups you save — a name, which market, and the three axis selections. Nothing else. It’s held in a Supabase (PostgreSQL) database with row-level security, readable only by your logged-in session, and not shared with anyone.

Deleting your data

On the Account page, “Delete account and all data” permanently removes your login record and every saved lookup, immediately. Signing out on its own deletes nothing. Lookups stored only in your browser are cleared when you clear site data for this domain.
