How buying once works
- €69, once. VAT included where it applies. No subscription, no account, no activation. The licence is a short text you paste into the app, on every computer you use.
- A year of updates. Every version released within a year of your purchase is yours. The app fetches them when you ask. The versions of that year keep working for good: nothing ever expires.
- After the year, the app keeps working as it is. It never updates itself to a version your licence does not cover. If you want the newer ones, another year is €39. It starts where the old one ended, so renewing early loses nothing.
- The free version is the trial. Try everything with one receiver for as long as you like. If Full turns out not to be for you, there is a 14-day refund.
- One licence per person, on the computers they use. A business buys one per user.
The full version is coming shortly. Until then, the free version has no time limit.
