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.
0xArchive is operated by Archive Labs Inc., a Delaware corporation.
2. Information We Collect
Account Information
When you create an account, we collect:

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.
0xArchive never asks for seed phrases or private keys and does not custody customer funds.

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

We share a hashed email and conversion events with OpenAI Ads to measure ad performance; we do not share raw email addresses for this purpose
- Customer Support: email, Telegram, and support requests
- Legal Requirements: When required by law or to protect our rights and safety

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.
- Advertising measurement cookies: the OpenAI Ads pixel loads on public pages only after you accept, to measure the performance of ads that brought you to the site. It records conversion events (such as sign-ups and purchases) for attribution. We also report these conversions to OpenAI Ads from our servers using a hashed email; we do not send raw email addresses.
- Functional cookies: account, checkout, and security workflows may store the state required for those service features.
Our consent banner lets you keep optional analytics and ad-measurement cookies enabled or reject them. If you reject, we deny optional analytics and ad storage for future public-page usage and stop Clarity and the OpenAI Ads pixel 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.
