License activation and transfer.

Three license tiers, one-time payment, no subscription. Activation takes 30 seconds.

1 · The three tiers

  • Annual · €99/year · 1 device · renew yearly
  • Lifetime · €149 once · 1 device · for life, no subscription
  • Practice · €199 once (intro, regular €249) · 3 devices in parallel · for practice PC + laptop + backup

All tiers include all updates of this app version (0.x). Major updates (1.0) free for Lifetime/Practice users.

2 · Get the activation code

After purchase you receive an email with code in format:

HTL-XXXX-XXXX-XXXX-XXXX

HTL = Lifetime, HTJ = Annual, HTP = Practice. Save the code — you'll need it for device transfers.

3 · Activate in the app

  1. Start app (license-gate appears without active license)
  2. Enter code (case auto-converted)
  3. Click „Activate"
  4. App contacts our servers briefly (1-3 sec), validates, registers your device
  5. License-gate disappears, app opens cockpit

Activation requires internet once. After that, app works fully offline — license stored as signed token locally.

4 · Device transfer (Lifetime / Annual)

  1. On OLD device: Settings → License → „Deactivate on this device"
  2. On NEW device: install app, enter same code

If your old device is broken and you couldn't deactivate: log in to the LemonSqueezy customer portal with the email from your purchase. You'll see your license there and can flag the activation for support — the device reset itself (as of 2026) still goes through the vendor backend, but is usually done within one business day.

5 · Practice license: 3 devices

Practice license allows 3 parallel activations. License dashboard online (login page) shows: active devices list, activation date per device, „Deactivate" button per device.

6 · No license = no app

Without activation, app shows license-gate — features unreachable. Not a trial mode with watermark — all or nothing.

7 · Refund

14-day refund period. Request the refund in the LemonSqueezy customer portal — open your order, request a refund. We confirm, money goes back to the original payment method (5-7 business days), license is centrally deactivated.
