Privacy Policy

Last updated: March 24, 2026

1. Introduction

0xArchive.io ("we", "our", or "us") is committed to protecting your privacy. This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our website and API services.

2. Information We Collect

Account Information

When you create an account, we collect:

  • Email address
  • Username (optional)
  • Password (stored securely using industry-standard hashing)
  • OAuth profile information (if you sign up via GitHub or Google)
  • Ethereum wallet address (if you sign up via SIWE/web3)
  • Marketing communication preference

Usage Information

We automatically collect:

  • API request logs (endpoints accessed, timestamps, response codes)
  • IP addresses
  • Browser type and version
  • Device information

Payment Information

We support two payment methods. For card payments, processing is handled by Stripe — we do not store credit card numbers or banking information, and receive only transaction confirmations and subscription status. For cryptocurrency payments, we process USDC payments on Base via the x402 protocol — we record your wallet address, transaction hash, and payment amount.

3. How We Use Your Information

We use the information we collect to:

  • Provide and maintain our services
  • Process transactions and manage subscriptions
  • Send important service updates and security alerts
  • Send marketing communications (only with your opt-in consent)
  • Enforce rate limits and prevent abuse
  • Improve our services and develop new features
  • Respond to customer support requests
  • Comply with legal obligations

4. Information Sharing

We do not sell your personal information. We may share information with:

  • Payment Processors: Stripe for card payments; on-chain transaction data for x402/USDC payments (publicly visible on Base)
  • Analytics Providers: Google Analytics (GA4) for website usage analytics and attribution, and Microsoft Clarity for public-page session replay and heatmaps
  • Customer Support: Tidio for live chat on public pages
  • Legal Requirements: When required by law or to protect our rights and safety
  • Business Transfers: In connection with a merger, acquisition, or sale of assets

5. Data Security

We implement appropriate technical and organizational measures to protect your personal information, including:

  • Encryption of data in transit (TLS/SSL)
  • Secure password hashing (Argon2)
  • API key hashing (SHA-256)
  • Regular security audits
  • Access controls and monitoring

6. Data Retention

We retain your account information for as long as your account is active. Usage logs are retained for 90 days for operational purposes. You may request deletion of your account and associated data at any time.

7. Your Rights

Depending on your location, you may have the right to:

  • Access your personal information
  • Correct inaccurate data
  • Delete your account and data
  • Export your data
  • Opt out of marketing communications

To exercise these rights, contact us at [email protected]

8. Cookies and Tracking

We use the following types of cookies:

  • Essential cookies: Session management and your cookie consent preference. These are always active.
  • Analytics cookies: Google Analytics (GA4) and Microsoft Clarity help us understand how visitors use our public site. GA4 loads on public pages to measure site usage and campaign attribution. Clarity also loads on public pages so we can understand product and content friction.
  • Functional cookies: Tidio live chat is available on public pages so visitors can contact us for support.

We do not use advertising cookies. Our consent banner lets you keep analytics storage enabled or reject it. If you reject, we deny optional analytics storage for future public-page usage and stop Clarity on public routes. Rejecting does not mean nothing loaded before your choice, and you can also clear cookies at any time through your browser settings.

9. International Transfers

Your information may be transferred to and processed in countries other than your own. We ensure appropriate safeguards are in place to protect your information in accordance with this Privacy Policy.

10. Children's Privacy

Our services are not intended for individuals under 18 years of age. We do not knowingly collect personal information from children.

11. Changes to This Policy

We may update this Privacy Policy from time to time. We will notify you of any material changes by posting the new policy on this page and updating the "Last updated" date.
