Cookie Policy
Last updated: March 14, 2026
This Cookie Policy explains how TradingWizard AI ("the Platform") uses cookies and similar technologies when you visit tradingwizard.ai. Essential cookies are always active. Analytics and marketing cookies are only set with your consent — we ask for it via the cookie banner on your first visit, and you can change your choice at any time.
What Are Cookies
Cookies are small text files stored on your device by your web browser. They help websites remember your preferences, keep you logged in, and understand how you use the site.
Essential Cookies
These cookies are required for the Platform to function and cannot be disabled.
| Cookie | Purpose | Duration |
|---|---|---|
| next-auth.session-token | Keeps you authenticated and maintains your login session. This cookie is set when you sign in and is essential for accessing your account. | Session / 30 days |
| next-auth.csrf-token | Protects against cross-site request forgery (CSRF) attacks during authentication. | Session |
| next-auth.callback-url | Stores the page you were visiting so you can be redirected back after login. | Session |
Referral Tracking Cookie
When you arrive at the Platform through a referral or affiliate link, we set a cookie to record the referral source. This is used solely for affiliate attribution — crediting the person who referred you.
| Cookie | Purpose | Duration |
|---|---|---|
| tw_ref | Stores the referral code from affiliate links for attribution purposes. | 30 days |
Analytics Cookies (consent required)
With your consent, we use analytics tools to understand how visitors interact with the Platform so we can improve it. These are only loaded after you accept the "Analytics" category in the cookie banner.
- PostHog — product analytics and session insights (page views, feature usage, session duration). Inputs are masked. Hosted in the EU.
- Google Analytics 4 — aggregate traffic measurement. Runs under Google Consent Mode, so no analytics cookies are set until you consent.
We also use Vercel Web Analytics and datafa.st for basic traffic counts. These are cookieless — they set no cookies and store no personal identifiers — so they run without consent.
Marketing Cookies (consent required)
With your consent, we measure the performance of our advertising so we know which campaigns bring people to TradingWizard. These are only loaded after you accept the "Marketing" category in the cookie banner.
- Google Ads — conversion measurement for our ad campaigns. Runs under Google Consent Mode (denied until you consent).
- Meta Pixel — conversion measurement for Facebook / Instagram campaigns. Only loaded after you accept marketing cookies.
Managing Cookies
You can review or change your choice at any time using the button below, the "Cookie Settings" link in the footer, or by clearing the tw_consent cookie. If you reject or later withdraw consent, analytics and marketing cookies are not loaded.
You can also control cookies through your browser settings. Most browsers allow you to block or delete cookies. However, if you block essential cookies (such as the NextAuth session cookie), you will not be able to log in to the Platform.
