The trial
Section titled “The trial”When you launch RDPMaster for the first time, RDPMaster issues itself a 15-day trial licence automatically. Every feature is available during the trial — there is no nag screen, no watermarks, no feature gates. You can use RDPMaster exactly as a paid customer would.
The trial pill in the top-right title strip shows Trial · N day(s) left. When N reaches 0, the next launch shows a Trial expired screen with three options: Buy, Activate, Export profiles.
Buying a licence
Section titled “Buying a licence”Click Buy in the trial-expired screen, or click the trial pill at any time during the trial. Your default browser opens to the Hudson Enterprises product page where you pick a tier:
| Tier | Price | Devices |
|---|---|---|
| Personal | $39 | 2 |
| Pro | $69 | 5 |
| Team 5-pack | $249 | 5 named seats |
Checkout is handled by Lemon Squeezy (Merchant of Record — they handle global VAT/sales tax). You’ll receive an email within seconds containing your licence key in the form XXXXX-XXXXX-XXXXX-XXXXX-XXXXX.
Activating
Section titled “Activating”Two ways into the activation dialog:
- Click the trial pill or Activate button after expiry.
- From the main window: Settings → Licence → Activate licence.
Paste the licence key. Click Activate.
What happens: RDPMaster computes a hardware fingerprint (BIOS UUID + motherboard serial + primary NIC MAC + Windows install ID, SHA-256 hashed), sends {licence_key, instance_name=fingerprint} to api.lemonsqueezy.com/v1/licenses/activate, receives an activation response, signs it locally with the embedded Ed25519 verifier, and writes a LicenseBlob to %APPDATA%\RDPMaster\license.dat. The pill in the title strip switches from “Trial” to your tier name.
Weekly re-check
Section titled “Weekly re-check”RDPMaster phones home to api.lemonsqueezy.com/v1/licenses/validate once a week to confirm the licence is still active (i.e. hasn’t been refunded or disabled).
- Success: silent. The licence’s offline-grace window extends by 14 days.
- Failure (network down, captive portal, etc.): silent. The 14-day offline grace handles short outages.
- Lemon Squeezy says “disabled” or “expired”: the licence enters a 14-day countdown. You see a warning banner. Email
support@hudsonenterprisesllc.comto dispute.
Moving to a new machine
Section titled “Moving to a new machine”Each licence tier has an activation limit (Personal = 2, Pro = 5, Team-5 = 5). If you replace a machine and exhaust your limit:
- Open the Lemon Squeezy customer portal (link in your purchase receipt email).
- Find your RDPMaster licence.
- Deactivate the slot for the old machine.
- On the new machine, activate as normal.
If you can’t find the receipt email, search lemon squeezy receipt in your mailbox or email support@hudsonenterprisesllc.com with your purchase email address; we can look it up.
Offline activation
Section titled “Offline activation”If your machine doesn’t have outbound HTTPS, contact support@hudsonenterprisesllc.com with your licence key and hardware fingerprint (Settings → Licence → Copy fingerprint). We’ll send back a pre-signed activation blob you can drop into %APPDATA%\RDPMaster\license.dat directly. Allow a business day for offline activation.
Refund window
Section titled “Refund window”Per the EULA + Lemon Squeezy customer portal, you have 14 days from purchase to request a refund. Open the LS portal, find your licence, click Request refund — no questions, no haggling.
Deactivating
Section titled “Deactivating”To stop using RDPMaster on a machine and free up the activation slot:
- Settings → Licence → Deactivate this device — RDPMaster calls Lemon Squeezy’s deactivate endpoint, then wipes the local
license.dat. Use this before reformatting or selling a machine.
