The Premium subscription is tied to the e-mail address of the Virtual Regatta account logged in to eSail4VR. With that account, it applies to all your devices: phone, tablet, Mac and Windows PC.
To prevent abuse, one subscription can be used with 5 Virtual Regatta accounts at most. Each time you log in to another Virtual Regatta account in eSail4VR, on a device where your App Store or Google Play subscription is active, that account is attached to your subscription.
At the 6th account, the subscription is blocked. Our server no longer records any update of this subscription, for any of the attached accounts, the buyer’s included. On PC and on your other devices, eSail4VR keeps the last recorded expiry date, then falls back to the free version: wind limited to 5 days, no expert mode.
If you think your subscription is blocked, write to us from the app: Settings > Contact us.
