License and fulfillment

What do I receive after I buy?

Lemon Squeezy emails your receipt, a license key, and a link to the installer. Card data never touches discivia.com — Lemon Squeezy is the merchant of record.

Is this a subscription?

No. The listed price is a one-time license for the current major version. Recurring billing is not used.

How many computers can I use?

The default license is for one person on up to two machines (for example a desktop and a laptop). Seat counts can be adjusted later in Lemon Squeezy if we publish a family or classroom SKU.

Where do I find my key later?

In the original Lemon Squeezy email, or in the customer portal linked from the Download page. Keep that email.

Can I get a refund?

Refunds are handled by Lemon Squeezy under their buyer protection policy. Contact us at the address on the Contact page if something went wrong with fulfillment.
