You pay once. The key arrives by email and you enter it once.
You buy once. There is no subscription. It is a lifetime license, valid for 100 years from the day it is issued.
After the payment goes through, your license key is emailed to the address on the order. Open the app and paste it in.
The app is made by Veue Management Corp. The sale is handled by our merchant of record, who is identified at checkout, so their name is what appears on your statement, and they handle the receipt, the tax and any refund.
A Personal license is for one person and covers all your personal Macs. Each person needs their own. For a company, see Buying for a team.
