Cookies are small text files placed on your device by websites you visit. They are widely used to make websites work efficiently and to provide information to site owners. We also use browser local storage, which serves a similar purpose.
SportChartz uses cookies and local storage for three purposes: essential functionality, user preferences, and analytics. We only load analytics cookies after you provide consent.
These are required for the Service to function. They cannot be disabled.
| Cookie / Storage | Provider | Purpose | Duration |
|---|---|---|---|
| Auth0 session cookies | Auth0 (Okta) | Authenticate your login session and maintain secure access | Session |
| Auth0 transaction cookies | Auth0 (Okta) | Secure the login/logout flow against cross-site request forgery | Session |
auth0.is.authenticated |
Auth0 (localStorage) | Remember that you are logged in | Until logout |
| Auth0 token cache | Auth0 (localStorage) | Cache your authentication token to avoid repeated login prompts | Until logout or token expiry (1 day) |
These remember your preferences to improve your experience. They do not track you across other websites. All functional data is stored in your browser’s localStorage and is never transmitted to our servers.
| Storage Key | Purpose | Duration |
|---|---|---|
Chart overlays (chart-overlays-{game_id}) |
Remember your overlay settings (SMA, EMA, odds) per game | Until cleared |
Chart indicators (chart-indicators-{game_id}) |
Remember your indicator settings (RSI, MACD, momentum) per game | Until cleared |
Chart attributes (chart-attributes) |
Remember global chart preferences (line thickness, colors) | Until cleared |
| League and team filters | Remember your selected league and team preferences | Until cleared |
| Game favorites | Remember which games you’ve marked as favorites | Until cleared |
These help us understand how the Service is used so we can improve it. They are not loaded until you provide consent via the cookie consent banner.

Google Tag Manager is only loaded on production domains (app.sportchartz.com, app.nextbetz.com) and only after you consent to analytics cookies.
We do not use cookies for advertising delivery, remarketing, or cross-site ad targeting. We do use one first-party cookie for marketing attribution (see sc_attr in Section 4.1), which records how you arrived at the site but does not track you across other websites.
The marketing site may set additional cookies:
| Cookie | Provider | Purpose | Consent Required |
|---|---|---|---|
| WordPress session cookie | WordPress | Maintain site session | No (essential) |
| X (formerly Twitter) widgets.js | X (formerly Twitter) | Embedded tweets and social content | Yes — only loaded after consent |

SportChartz (first-party, 6 months) | Records your first-touch acquisition source (the campaign, referrer, or ad that brought you to the site) so signups can be attributed to a marketing channel. Not used for ad delivery, remarketing, or cross-site tracking. | Yes in the EU/UK/EEA (set only after you accept the Advertisement category); set by default with an opt-out elsewhere. |
X’s embedded content may set its own tracking cookies. These are governed by . We defer loading X widgets until you consent to third-party cookies.
We use CookieYes to manage your cookie preferences. CookieYes sets its own cookie to remember your consent choice:
| Cookie | Purpose | Duration |
|---|---|---|
cookieyes-consent |
Stores your cookie consent preferences | 1 year |
You can change your cookie preferences at any time by clicking the cookie settings link in the footer of the Service, which will reopen the CookieYes consent banner.

Some browsers send a “Do Not Track” (DNT) signal. There is no industry standard for how websites should respond to DNT signals. We do not currently respond to DNT signals, but we do not load analytics cookies without your explicit consent regardless of DNT settings.
We may update this Cookie Policy from time to time. When we do:
We will update the “Last Updated” date and version number at the top of this page
If we add new categories of cookies or change how we use existing ones, we will reset your consent preferences and ask you to consent again
