What we collect

When you join the waitlist, we collect your email address and first name. These are stored in Resend Audiences and used only to send you updates about Haiku.

Analytics

We use Vercel Analytics to collect anonymous page-view data. No personal information is included in analytics events.

Install telemetry

When you install Haiku, the installer sends one ping at the start of the install and one at the end so we can measure adoption and diagnose install failures. The same happens when you run haiku uninstall.

Each ping includes only: your macOS version, CPU model, RAM size, free disk size, whether Xcode is installed, the Haiku version being installed or removed, an anonymous install ID (see below), and your country. The country is derived server-side from your IP address, which is then immediately dropped — we never store your IP.

The anonymous install ID is a one-way SHA-256 hash of your machine's hardware UUID:

sha256("haiku-install-v1::" + <your IOPlatformUUID>)

You can reproduce this locally to verify what we receive. The original hardware UUID never leaves your machine; the hash is stable across reinstalls so we can count unique machines without identifying you.

We never collect: your username, hostname, IP address, MAC address, hardware serial number, file paths, the contents of your .haiku files, or anything you do inside the Haiku CLI.

To opt out, set HAIKU_NO_TELEMETRY=1 in your environment before running install.sh or any other Haiku command. The pings will not be sent.

The source code for both the script that sends these pings and the Cloudflare Worker that receives them is open in the repo —applications/haiku/build/install.sh and applications/haiku/platforms/cloudflare/telemetry/worker.ts. Verify for yourself.

Email communications

After joining the waitlist you will receive a confirmation email sent via Resend from hello@haiku.run. You can unsubscribe at any time by replying to any email.
