COOKIE POLICY

Last Updated: January 26, 2026

1. Introduction

This Cookie Policy explains how Miew ("Company", "we", "us", and "our"), the developer of the Koltena platform, uses cookies and similar technologies to recognize you when you visit our website at .

Since Koltena is a Web3 gaming platform involving financial interactions and external gaming profiles, we use specific technologies to ensure security, authentication, and gameplay integration.

2. What are Cookies and Local Storage?

Cookies:

Small data files placed on your device to help websites work efficiently.

Local Storage:

A standard web technology that allows us to store data in your browser. Unlike cookies, this data is not sent to the server with every request.

Why we use them:

In the world of Web3 and Gaming, Local Storage is critical. It allows us to keep you logged in to your Blockchain Wallet and maintain your connection to services like Steam and Discord without forcing you to re-authenticate constantly.

3. Key Integrations & Data Sources

Our platform integrates with several third-party providers to function correctly. These providers may set their own cookies or use local storage on your device:

  • Authentication (Social Login): We allow you to log in using Google (Gmail) and Discord. These services use cookies to verify your identity and maintain your session.
  • Gaming Profiles: We integrate with Steam via OAuth to verify your gaming statistics and ownership. This connection requires session tokens to validate your Steam ID.
  • Blockchain Wallets: We interact directly with browser extensions like MetaMask.

4. Categories of Technologies We Use

A. Strictly Necessary (Essential)

These are vital for the platform to function. They cannot be switched off.

  • Session Management: To keep you logged in after you authenticate via Google, Discord, or Email.
  • Security: To prevent Cross-Site Request Forgery (CSRF) and protect your account from unauthorized access.
  • Wallet State: We use Local Storage to remember which wallet (e.g., MetaMask) you have connected, ensuring a seamless experience when you refresh the page.

B. Functionality & Integration (Social & Gaming)

These are used when you actively choose to use a specific feature.

  • Steam Integration: When you link your Steam account, we store a token that allows us to read your public gaming data (as permitted by you) to verify tournament eligibility or asset ownership.
  • Discord Integration: Used to map your Discord role to your Koltena Team status.
  • Google Auth: Used strictly for authentication purposes if you choose to sign in via Gmail.

C. Performance & Analytics

Vercel Analytics: We use Vercel (our hosting provider) to monitor the technical performance and speed of our application. This data is aggregated and anonymous.

5. Blockchain Transparency

Please be aware that Koltena operates on public blockchains (Base/Ethereum).

  • Public Ledger: Transactions you sign with MetaMask are recorded on the blockchain forever. This is not a "cookie" and cannot be deleted by us.
  • Privacy: While your wallet address is public, we do not link it to your real-world identity (Google/Steam ID) on the public blockchain without your explicit action (e.g., creating a visible Team Profile).

6. Third-Party Policies

When you use social logins or gaming integrations, you are also interacting with those platforms. We encourage you to read their policies:

7. Managing Your Preferences

You can control cookies through your browser settings. However, please note:

Blocking Local Storage or Strictly Necessary Cookies will break the application. You will not be able to connect your MetaMask wallet, link your Steam account, or log in via Discord.
