Cookies policy.
We use only one cookie, and it's the kind every login-based service legally needs (a session cookie). No tracking cookies, no advertising cookies, no third-party cookies. This page explains what's actually being set in your browser.
1 · The session cookie
Cookie name: fxbd_session
Purpose: remembers that you're signed in so you don't have to log in on every page. Stores a signed reference to your session — not your password, and not your personal data.
Set when: you sign in (email/password or Google).
Expires: 30 days after the cookie was set. We also invalidate it when the London date rolls over (so a session is good for the rest of "your day" but expires overnight, forcing a fresh login each trading day).
Without it: the site doesn't work. You'd have to log in on every page-load. There is no opt-out for this cookie specifically because it's "strictly necessary" under UK GDPR / PECR rules — the consent requirement doesn't apply to cookies that are essential for the service the user is requesting.
2 · Local storage (not technically a cookie, but related)
fxbd:theme— remembers your light/dark theme choice so the next page-load doesn't flash the wrong colours.fxbd:lastSeenAt— a timestamp used by the mid-session "welcome back" recap modal. It only stores a timestamp; no personal data.
These live in your browser's localStorage, not as
cookies, so they never get sent to the server. You can clear them
any time via your browser's developer tools or by clearing the
site data for fx-bias-dashboard.fly.dev.
3 · Third-party cookies we don't set
- No Google Analytics, no Mixpanel, no Hotjar, no advertising pixels. You won't be remarketed at across the internet because of visiting this site.
- No Facebook pixel, no LinkedIn tag, no TikTok pixel.
- No CDN-side tracking cookies. Our CSS / fonts are loaded from Google Fonts and unpkg.com — those services may log requests for caching purposes, but they don't drop a cookie on your browser through us.
4 · How to control cookies
Every modern browser lets you block or delete cookies. If you
block the fxbd_session cookie specifically, the
dashboard won't let you stay logged in — that's not a privacy
issue, it's a feature of how login works. There's no way to use
a login-based service without a session cookie.
