# Activating Your License

Astro PM can be explored in trial mode, and a license key unlocks the full product. This page covers purchasing, entering your key, and what changes when you activate.

### Purchasing a License

Licenses are sold on the [**Buy License**](https://astro-pm.com/astro-pm-license/) page. After checkout your license key is emailed to you. Keys look like this:

`ASTROPM-XXXX-XXXX-XXXX`

### Entering Your Key

Open Astro PM’s license screen, paste your key exactly as it appears in the email, and apply. Activation validates the key online, so make sure the computer has an internet connection at that moment.

### Trial vs. Licensed

Trial mode includes the full planning experience with some capacity limits – for example, the number of targets that can be pushed to the cloud for NINA is reduced. Activating your license lifts these limits for your whole setup: the desktop app, the NINA plugin, and the phone app all recognize your licensed account through the cloud sync.

### Moving to a New Computer

Install Astro PM on the new machine and activate with the same key. If you run into an activation limit after a rebuild or hardware change, contact [support](https://astro-pm.com/contact-us/) and we will reset it for you.
