Privacy Policy for Electrum-CAT (V4.5.9)

Last updated: September 12, 2025

Thank you for using Electrum-CAT, a lightweight and secure Catcoin wallet based on the proven Electrum architecture. This Privacy Policy explains how Electrum-CAT handles your personal information - which, in short, is very minimal. We believe in privacy by design.

About Electrum-CAT

Electrum-CAT is a desktop and mobile Catcoin wallet forked from Electrum-GRS v4.5.4 in February 2025, which in turn is a derivative of the original Electrum BTC wallet. It is developed and maintained by:

No Personal Data Collection

Electrum-CAT is a self-custodial, open-source, and non-custodial cryptocurrency wallet. We do not collect, store, or transmit any of your personal data. Specifically:

  • No account registration is required.
  • No name, email, phone number, or address is collected.
  • No telemetry or analytics are embedded.
  • No usage data or behavioral data is recorded.

Self-Custody and Local Encryption

  • Your wallet's private keys and seed phrase are generated and stored locally on your device.
  • These sensitive credentials are never transmitted to our servers or third parties.
  • Private data is encrypted using strong industry standards (e.g., AES-256) and is decrypted only when required to sign a transaction.

Network Privacy and IP Address

While Electrum-CAT does not track users, it connects to ElectrumX servers to retrieve blockchain data and broadcast transactions.

  • When you connect to public Electrum servers, your IP address may be visible to those servers.
  • You can optionally run your own ElectrumX server for enhanced privacy, completely eliminating reliance on third-party nodes.

Optional Server Hosting

To enhance privacy, advanced users may:

  • Host their own ElectrumX server.
  • Configure Electrum-CAT to connect only to trusted nodes.
  • Use anonymity networks (e.g., Tor or VPNs) to obfuscate IP addresses.

Third-Party Access

  • Electrum-CAT does not share your data with any third party.
  • There are no embedded analytics, ads, or tracking libraries.
  • We do not use cloud-based infrastructure that processes user wallets or transactions.

Your Responsibilities

You, the user, are fully responsible for:

  • Backing up your 12-word seed phrase securely.
  • Preventing unauthorized access to your device.
  • Not sharing your private keys or passwords.

If you lose your seed phrase, we cannot help you recover your wallet.

Security Disclaimer

Although Electrum-CAT is designed with security in mind:

  • No software is immune to vulnerabilities.
  • Users are encouraged to download the wallet only from the official website or GitHub repository.
  • Always verify the wallet signature or checksum before installing any binary.

Compliance and Distribution

Electrum-CAT is designed to meet privacy and data protection standards required by major software distribution platforms, including the Microsoft Store, GitHub, and third-party open-source aggregators.

Inheritance of Electrum Privacy Practices

As a fork of Electrum-GRS and ultimately Electrum BTC, Electrum-CAT inherits the core privacy and security philosophy of Electrum:

  • You control your private keys.
  • No central server or authority can access your funds.
  • Trust minimization and client-side verification are central to its design.

Changes to This Privacy Policy

This Privacy Policy may be updated occasionally. When updated, we will post the revised policy with the new "Last Updated" date. Continued use of Electrum-CAT implies acceptance of any revised terms.
