What Are Cookies?
Cookies are small text files stored on your device by your browser when you visit a website. They help websites remember information about your visit - such as whether you are logged in - so you do not need to re-enter details on every page.
Cookies We Use
Yestercharts uses a small set of cookies: the ones needed to run the service, plus Google Analytics to understand how visitors use the site. We do not use advertising or social media tracking cookies.
| Name | Purpose | Type | Expires |
|---|---|---|---|
| sb-*-auth-token | Keeps you logged in. | Strictly necessary | Session |
| sb-*-auth-token-code-verifier | Secures sign-in. | Strictly necessary | Session |
| _ga | Google Analytics: tells visitors apart. | Analytics | 2 years |
| _ga_* | Google Analytics: remembers your session. | Analytics | 2 years |
We use no advertising cookies and no social media tracking pixels. Analytics cookies are optional and only help us improve the site.
Local Storage
In addition to cookies, Yestercharts uses browser localStorage to store non-sensitive UI preferences (e.g., chart settings, selected contest type). This data never leaves your device and is not transmitted to our servers.
How to Control Cookies
The login cookies are required to use Yestercharts, so disabling all cookies will prevent you from signing in. Analytics cookies are optional. You can clear or block cookies at any time via your browser settings - clearing them will sign you out.
