4. Third-Party Cookies
Some features of CrackChart rely on third-party services that may set their own cookies. These include:
Vercel Analytics: Used for anonymised, privacy-first analytics about platform performance. Vercel does not sell data or use it for advertising purposes. See vercel.com/legal/privacy-policy.
Payment Processors: If you interact with wallet top-up or withdrawal flows, our payment processors (e.g., Stripe) may set session cookies to process your transaction securely. These are governed by the processor's own privacy and cookie policies.
We do not load third-party advertising scripts, social media tracking pixels, or any cookies from ad networks.
5. Your Cookie Choices
Essential cookies cannot be disabled as they are required for the Platform to function. For all other cookie categories, you have the following options:
Browser Settings: Most web browsers allow you to refuse or delete cookies through their settings. Refer to your browser's help documentation for instructions. Note that disabling certain cookies may affect the functionality of the Platform.
Opt-Out Tools: You can opt out of analytics tracking via Vercel's privacy controls at vercel.com/legal/privacy-policy.
Do Not Track: We respect the Do Not Track (DNT) signal where technically feasible. When DNT is enabled, we will not load non-essential tracking scripts.
6. Updates to This Policy
We may update this Cookie Policy from time to time to reflect changes in our practices or for operational, legal, or regulatory reasons. When we make material changes, we will update the "Last updated" date below and notify registered users via the Platform or by email.
Your continued use of the Platform after the effective date of any update constitutes acceptance of the revised Cookie Policy.
