Cookie Policy
Last updated: 30 October 2026
Applies to: xΛTrader's pages
In short. xΛTrader sets the cookies it needs to sign you in and to keep its forms and the Service safe, one that remembers your theme, and Google Analytics cookies that measure how the Service is used.
1. What cookies are
Cookies are small pieces of text a website asks your browser to keep and to send back on later visits. Some are needed for a website to work; others remember a choice, or measure how a website is used.
2. The cookies xΛTrader uses
| Cookie | Set by | What it does | Kind | How long |
|---|---|---|---|---|
xATC_Token | xΛTrader | Keeps you signed in. Scripts on a page cannot read it, and it is sent only over encrypted connections | Strictly necessary | 30 minutes, or 30 days if you choose "Remember me" |
.AspNetCore.Session | xΛTrader | Holds short-lived state between pages | Strictly necessary | Until you close the browser; its contents expire after 30 minutes without use |
.AspNetCore.Antiforgery.… | xΛTrader | Proves that a form was sent from xΛTrader's own page, so another website cannot submit it in your name | Strictly necessary (security) | Until you close the browser |
xat_vid | xΛTrader | Tells one browser from another, so that misuse — scripts, floods of requests, forged links — can be found and limited. A random number signed by our server; nothing about you is in it, and scripts on a page cannot read it | Strictly necessary (security) | 180 days |
.AspNetCore.Mvc.CookieTempDataProvider | xΛTrader | Carries a one-time message, such as "saved", to the next page | Strictly necessary | Removed as soon as it has been shown |
xat-theme | xΛTrader | Remembers the light or dark theme | Preference | 1 year |
_ga, _ga_… | Google Analytics (Google) | Tell visits apart, so that Google Analytics can count how pages are used | Analytics | Up to 2 years |
__cf_bm, cf_clearance | Cloudflare | Once xΛTrader is open to the public: set only when Cloudflare checks whether traffic comes from a person or an automated program | Strictly necessary (security) | 30 minutes (__cf_bm); as long as a check is valid (cf_clearance) |
3. Your browser's storage
xΛTrader also keeps a few display preferences in your browser's local storage, such as the theme and the order of the market tabs on the home page. They stay on your device and are not sent to us.
4. Managing cookies
You can block or delete cookies in your browser's settings. If you block the strictly necessary ones, you cannot sign in. To stop Google Analytics, block its cookies in your browser, or use Google's Analytics opt-out browser add-on; xΛTrader works the same without them.
