Every installer above lists the SHA-256 its build produced. Compare it against the file you received before running it — if the two differ, do not run the file.

Before you install

System requirements

macOS

macOS 13 or later on an Apple silicon Mac, and an administrator password. The installer refuses an older macOS and Intel Macs.

Windows

Windows 10 or later, or Windows Server 2016 or later, on an x64 PC, with administrator rights. Set up Windows Hello (a PIN, fingerprint or face) before you add your first passkey.

Linux

Ubuntu 24.04 or Debian 13 or newer, on amd64 (glibc 2.38 and systemd 242), with sudo, and zenity or kdialog for the companion's dialogs. Other Linux systems and arm64 can use pipx install privacyfence, which runs as you and is not privilege-separated.

Platform support has every supported version, where PrivacyFence keeps its data, and its logs.

What the installer does

What ends up on your computer

macOS

The DMG holds PrivacyFence.pkg and the Claude Desktop extension, PrivacyFence.mcpb. The package installs /Applications/PrivacyFenceApp.app, creates the _privacyfence service account, runs PrivacyFence under it, and starts the menu-bar icon at each login.

Windows

The installer puts PrivacyFence in %ProgramFiles%\PrivacyFence\, runs it as the PrivacyFence Windows service under its own account, keeps your data in %ProgramData%\PrivacyFence\, and starts the tray icon at each sign-in. Its last page offers the Claude Desktop extension.

Linux

The .deb puts a self-contained PrivacyFence in /opt/privacyfence, runs it as the privacyfence-daemon system service under the privacyfence account, keeps your data in /var/lib/privacyfence, and adds a PrivacyFence entry to your Applications menu.

Every installer runs PrivacyFence under its own service account, so an AI client running as you cannot read or change its policy, passkeys, audit log or connector credentials. Log out (on Windows, sign out) and back in once after installing, so your account can reach it.

After you install

Next steps

  1. Follow the install guide for your platform: macOS, Windows or Linux. Each one covers the first start, troubleshooting and uninstalling.
  2. Connect Gmail, Slack or another service from PrivacyFence's Settings: Connecting a service.
  3. Connect your AI client. AI agents has a page for each tested client, with its setup steps.
