# Licenses and updates - Bookline 1.x documentation

> Activate your license key for updates, move it to another site, and what happens when it expires.

> [!NOTE]
> This is part of **Bookline Pro**.

Your license lets your site download Bookline Pro updates. The features keep working without it.

## Activate

1. Go to **Plugins**. Under **Bookline Pro** there's a box asking for your key.
2. Paste the key from your purchase email and click **Activate** (or press Enter).

The box turns green and shows the key's last characters and when updates run until. Updates then appear on **Dashboard → Updates** like any other plugin's.

An **All Access** key works too: it covers every Extendiment plugin. Enter it under each plugin you use; on one site they all share a single activation, so a 1-site key covers every plugin on that site.

## Move it to another site

Click **Deactivate license** under Bookline Pro on the old site, then activate the key on the new one. (With an All Access key, deactivate it under every Extendiment plugin there: the activation is freed with the last one.) Deleting the plugin with "Delete it permanently" chosen frees the activation too.

## When it expires

Updates stop, and the box says so. Renew from your purchase email, then activate the key again. Bookline Pro keeps working in the meantime.

## Troubleshooting

- **"This license key is already active on all the sites it allows."** Deactivate it on a site you no longer use (or in your Lemon Squeezy customer portal).
- **"Couldn't reach the license server."** Your host blocks outgoing connections to extendiment.com; ask them to allow it.

## Staging and development sites

Staging and local sites don't count toward the sites your key allows. Activate the key there as on any site; the Plugins screen then says it's a staging site. Each key gets three of these. Extendiment tells them apart by the site's address: a `staging`, `dev` or `test` subdomain or folder, a `.local` or `.test` address, a local address, or your host's staging domain. Beyond three, a staging site counts like any other.

You can also leave the license inactive on a staging copy: the features work without it, only updates don't download there.

## Notices from Extendiment

Now and then Bookline Pro shows a short notice from Extendiment at the top of the dashboard, to admins who can manage plugins: a security update to install, or a sale on All Access. Close one with its **×** and it stays closed, for every Extendiment plugin on the site. A security notice has no **×**: it goes once the update is installed. These notices come with the update check, so nothing extra is sent.

## What's sent, and when

The license check sends **only your license key, the plugin's name and your site's address**, and only to extendiment.com, which checks the key with Lemon Squeezy. It happens at three moments: when you activate the license, when you deactivate it, and once a week to check it's still valid.
