Activation

Your license key looks like:

PRSM-XXXX-XXXX-XXXX-XXXX

It was emailed to the address you used at checkout (and shown on the post-purchase download page).

Activate

  1. Open PowerPoint and click refractions in the Home ribbon.
  2. Paste your license key into the Enter License Key field.
  3. Click Activate.

The daemon contacts https://refractions.app/api/validate-license/, registers your Mac, and the task pane switches to the normal chart editor.

How seats work

Tier Seats
Individual 1 Mac
Lab 5 Macs

Each Mac is identified by a SHA-256 fingerprint of its hostname and primary MAC address — it's stable across reboots and is not personally identifying.

The daemon re-validates the license once every 24 hours. If refractions.app is unreachable, refractions uses the cached validation for up to 7 days.

Activating on a new Mac

If you've used all your seats and need to activate a new Mac:

  1. Email [email protected] with the license key and the hostname of the Mac you want to deactivate.
  2. We'll free a seat within one business day.
  3. Activate the new Mac as usual.
