# Licensing

> FOAM trial, activation, and licensing

## How Licensing Works

FOAM uses server-managed licensing through nomn.jp. To produce sound you need a valid trial or full license key entered in the plugin.

If you launch FOAM without entering a key, you'll see **"Unlicensed"** in the credits bar at the bottom and audio output will be muted. Click that text to open the license dialog.

## Free Trial

1. Visit [nomn.jp](https://nomn.jp) and register a free account
2. Go to the FOAM product page and click **Free Trial**
3. A 5-day trial license key will be issued to your account immediately
4. Copy the key from your account dashboard
5. In FOAM, click **Unlicensed** in the credits bar and paste the key

The trial gives you full functionality for 5 calendar days. No payment information is required.

## Purchasing

1. Visit [nomn.jp](https://nomn.jp)
2. Create an account (or log in)
3. Navigate to FOAM and click **Buy**
4. Complete checkout via Stripe
5. Your full license key appears immediately in your account dashboard
6. Enter the key in FOAM the same way as a trial key

## Activation

1. In FOAM, click the **Unlicensed** text (bottom credits bar)
2. Paste your license key (format: `FOAM-XXXX-XXXX-XXXX`)
3. FOAM contacts the nomn.jp server to validate
4. On success, the credits bar updates to **Licensed** or **Trial** with days remaining

## Offline Use

After initial activation, **full licenses** work fully offline — your license is cached locally and does not require an internet connection for subsequent launches.

**Trial licenses** revalidate against the server periodically. If you're offline when your trial period ends, the plugin will continue to work until it can reach the server again.

## Multiple Machines

Each license supports up to 3 activations across different machines.
