Cookie Policy

Last updated: April 25, 2026


What are cookies?

Cookies are small text files stored on your device by a website. They help websites work, keep you signed in, and remember preferences. We also use similar browser-storage technologies such as localStorage and sessionStorage. This Policy explains what we use and how you can control it.

How we use cookies on MineralCache

  • Essential (required): Keep you signed in, protect your account, and let checkout, billing, auctions, and vendor tools work. Without these, the site cannot function correctly.
  • Preferences: Remember choices such as theme, layout state, legal-prompt progress, and dismissed notices so you do not have to set them every time.
  • Payments and security: Support secure payments, saved payment methods, payout onboarding, fraud prevention, and checkout reliability through providers like Stripe.
  • Performance and analytics: MineralCache does not currently run a separate non-essential analytics or advertising cookie tool. If we enable non-essential analytics later, we will update this Policy and provide any choices required by law.
  • Advertising: We do not use third-party advertising cookies on MineralCache at this time.

Cookie-like technologies

  • localStorage or sessionStorage: stored in your browser by the site. We use these for non-sensitive flow state and preferences, such as theme preference, agreement prompts, auction EU/UK notice acknowledgement, dismissed notices, and UI collapse state.
  • Third-party scripts required for payments and security: checkout, saved-card flows, and vendor payout onboarding may load Stripe scripts or related storage needed for secure payment and fraud prevention.
  • No separate advertising or analytics pixel tool is active today: if that changes later, we will update this Policy and any consent choices required by law.

Names and durations may change as we improve the site or our providers update their services. We will keep this page current and describe the categories of storage and cookies we actually use.

Your choices

  • Browser settings: most browsers let you block or delete cookies and clear localStorage or sessionStorage. Doing so may break essential features like login, checkout, billing, auctions, or vendor tools.
  • Payment flows: blocking third-party cookies or scripts used by Stripe may interfere with checkout, saved payment methods, and vendor payout onboarding.
  • Non-essential analytics or advertising: MineralCache does not currently run a separate analytics or advertising cookie preference center because those non-essential tools are not active today. If that changes later, we will update this Policy and provide any choices required by law.
  • Global Privacy Control (GPC): where required by law, we honor supported global opt-out signals like GPC for applicable processing.

How we keep cookies secure

Sensitive cookies, like session cookies, are set with security attributes where supported, including HttpOnly, Secure, and SameSite. We regularly review our use of cookies and providers to maintain security and privacy.

International visitors

If you access MineralCache from outside the United States, information associated with cookies or similar technologies may be processed in the United States and in other countries where our service providers operate. Depending on your location, local law may provide additional rights or consent requirements relating to cookies, browser storage, or similar technologies.

Children

MineralCache is for users 18+. We do not knowingly use non-essential cookie or browser-storage technologies on children's accounts.

Changes to this Cookie Policy

We may update this page as our site or laws change. Material updates will be posted here, and your continued use of MineralCache means you accept the updated Policy.
