license upgrade

Keep your writing tools current for less.

Enter the license key you already own. Checking it here sends a one-time discount code to the email address from your original purchase — you will enter that code below to continue to checkout. Starting from the app instead skips this step: an already-activated installation can request the code itself and open checkout with it already applied.

However you get the code, the new key it buys is delivered to your original purchase email or straight to the app, never to whatever email you use at checkout.

Paid upgrades have a 30-day refund window. A refund revokes only the new key from that purchase and reopens this key's discount eligibility; this key is untouched and keeps working for the major version it already owns.

1. Check your license

Use the key from your original purchase email or from Thruline’s Settings → License section.

Do not have your key? Recover it by email first, then return here.
