Privacy Policy

Effective as of: March 12, 2024

About this Privacy Policy

This Privacy Policy describes the privacy practices of Arkham Intelligence, Inc. (“Arkham,”) , and the Arkham Foundation (“the Foundation”) (collectively, “we,” “us” and “our”), and how we collect, use, and disclose personal data on our platform (collectively, the “Services”). We may update this Privacy Policy from time to time, as detailed below. You should not use the Services if you have any objections to our Privacy Policy, which is binding upon all users of the Services. If you have a question about how your personal data is being used, you can contact us through the methods provided in the “Contact Us” section at the end of this Privacy Policy.

Our Privacy Approach

First, here are a few key points about Arkham’s and the Foundation’s privacy practices:

  • Our Services are designed to provide a software platform for accessing blockchain information and analysis on entities, individuals, and transactions. We provide technology for linking cryptocurrency activity to real world individuals and institutions, including a searchable database of crypto users and their activities, customizable alerts for on and off chain activity, and network maps of crypto currency transactions across entities, individuals and geographies.
  • To provide you with our Services, we collect information directly from you, your use of the Services and public sources, such as blockchains.
  • We respect the privacy of our users. User labels, user created entities, and user imported addresses are stored securely and will not be used for the public dataset on the Arkham platform. We do not sell user personal information.

What Do We Mean by “personal data”?

Personal data is information that identifies, relates to, describes, is capable of being associated with, or could reasonably be linked, directly or indirectly, with a particular individual or household. Personal data that is publicly available, processing in connection with journalistic purposes or expression or a matter of public concern, aggregated, or de-identified is not considered personal data for the purposes of this Privacy Policy.

What Personal Data Do We Collect and How Do We Collect It?

Information you provide us.

Personal data you may provide to us through the Services includes:

  • Account and contact data, such as your first and last name, organization name (if applicable), biography (if you choose to add one), email and mailing address, Ethereum public address, phone number, profile picture, and username.
  • Interests, usage, and connections, including information about how you use the Services, such as the types of content you engage with, content you share, features you use, actions you take, and people or accounts you interact and connect with.
  • Marketing data, such as your preferences for receiving our marketing communications, and details about your engagement with them.
  • ‍Communications that we exchange with users when they contact us, including with questions or feedback.
  • Transaction information. Please note that for conducting any transactions through the Service, we work with third-party electronic wallet extensions such as MetaMask and WalletConnect. Your interactions with third-party electronic wallet extensions are governed by those businesses’ own privacy policies.
  • Blockchain addresses, including account information from third party wallet providers, and the associated crypto holdings and transaction data.
  • Other data not specifically listed here, which we will use as described in this Privacy Policy or as otherwise disclosed at the time of collection.

Intel Marketplace. Our platform provides a web app interface for users to interact with the Arkham Intel Exchange, a decentralized smart contract system, to facilitate—between users—the exchange of information, potentially including personal data, about individuals who are not users of the Services (“non-users”). In these instances, we may not know how or from where the personal data was originally collected. Personal data collected about non-users may come from a variety of internet or other sources. This information could include: non-users’ personal identifiers and the details of non-users’ blockchain transactions, including current and historical point-in-time holdings; balance history and historical profit and loss; and transaction history.  The Foundation processes this personal data of non-users when it uses its proprietary technology to verify a user’s intelligence. The Foundation may contract the Company to provide services related to the Intel Exchange which may involve the Company processing Intel Exchange data.  ‍

Third party sources. We may combine personal data we receive from or about you with information we obtain from other sources, such as:

  • Public sources, including blockchains and social media companies.
  • Marketing partners, such as companies that have entered into joint marketing relationships with us.

Automatic data collection. We, our service providers, and our business partners may automatically log information about you, your computer or mobile device, and your interaction over time with the Services, our communications, and other online services, such as:
