Cookie Policy
Last updated 26 October 2026
quant.trading uses only the cookies and browser storage it needs to work. There are no advertising, analytics or social-media cookies, so we don't ask you to accept any.
Cookies
| Name | What it does | How long |
|---|---|---|
connect.sid | Keeps you signed in. Set only when you sign in. | 7 days |
ih_trust | Remembers a device you said you trust, so you aren't asked for an emailed sign-in code every time. | 30 days |
Both are strictly necessary for a service you asked for, and are only ever read by quant.trading.
Browser storage
The app keeps your settings in your browser's local storage: things like your theme, layout, watchlist, chart and panel choices, drafts, the email you last requested access with (so the form remembers it), and the Hyperliquid trading key if you use Live trading. This stays on your device; clear it at any time in your browser's settings.
Third parties
Pages load fonts and scripts from quant.trading's own servers. A few signed-in tools load code libraries from public code servers (unpkg.com, cdn.jsdelivr.net), which see your IP address as any website you load files from would, but set no cookies. Live trading connects to Hyperliquid, and payments open Stripe's checkout, each under its own policy.
If this changes
If we ever add analytics or other cookies that aren't strictly necessary, we will ask for your consent first and update this page.
