Introduction

BiuBiu Tools is committed to protecting your privacy. This Privacy Policy explains how we collect, use, and safeguard your information when you use our Web3 tools and services.

Data We Collect

We collect different types of data depending on your consent preferences:

Essential Data (Always Collected)

  • Session data required for website functionality
  • Consent preferences to remember your choices
  • Theme preferences (light/dark mode)
  • Language preferences
  • RPC performance metrics for optimal network selection

Analytics Data (Cookie-Free, Always Enabled)

  • Aggregated, non-identifiable visitor metrics
  • Referral source tracking for our referral program

Local Storage (Necessary)

We use your browser's local storage to save data that is essential for the app to function. This data stays on your device and is not transmitted to our servers:

  • Custom token lists you've added (required for token operations)
  • Session data for multi-step operations (required to resume interrupted tasks)

Analytics

We use Rybbit (tj.appsdata.org), a privacy-focused, cookie-free analytics service to understand how visitors use our website. Rybbit does not use cookies, does not collect personally identifiable information, and is always enabled as it complies with GDPR without requiring consent. If we add additional analytics services in the future that use cookies, they will only be loaded with your consent. We interact with blockchain networks (Ethereum, Polygon, etc.) as required by our tools, but we do not store your private keys or seed phrases on our servers.

Under GDPR, CCPA, and similar regulations, you have the following rights:

  • Right to access: You can request information about what data we have about you
  • Right to erasure: You can clear your local data at any time through your browser settings
  • Right to withdraw consent: You can change your cookie preferences at any time
