How can we help?

Answers about your account, payments and the app. If you can’t find what you need, write to us and a real person will reply.

Contact support

We usually reply within 1–2 days. Tell us the email you bought with and, if something isn’t working, what you see (a screenshot helps a lot).

Buying and your account

I’ve paid. What happens now?

Your account is created automatically with the email you used to pay. In a few minutes you’ll get an email from [email protected] with a button to choose your password.

  1. Choose your password with that button.
  2. Download the app and install it.
  3. Open it and sign in with your email and that password.

If you already had an account with that email, you don’t get a new one: your license is simply activated.

The email hasn’t arrived

Check your spam or “Promotions” folder and search for kaidanisland. If it isn’t there after 15 minutes, open the app and use “Forgot your password?” with the same email: you’ll get a new link. Still nothing? Write to us.

I forgot my password, or the link expired

On the app’s sign-in screen, click “Forgot your password?” and enter your email. The link in that email is valid for a limited time; if it expires, just ask for another one.

Can I change the email of my account?

Yes. Sign in to your account and go to Sign-in and security › Email › Change. We’ll send a link to the new address; your email changes when you open it, and we let the old one know.

Plans and payments

How does the free trial work?

You get 7 days free and then it’s 7.99 € a month. We ask for a card to start the trial, but nothing is charged during those 7 days; if you cancel before the trial ends, you pay nothing.

The free trial is once per person: if your email, card or PC has already used one, you can still subscribe, but you’re charged from the first day.

Which payment methods do you accept?

Credit and debit cards (Visa, Mastercard, American Express…) and the other methods shown on the payment page, depending on your country. Payments are processed securely; we never see your card details. Prices include VAT.

Where can I get my invoice or receipt?

You get a receipt by email after each payment. Your receipts and invoices are also in your account, under Payments. If you need an invoice with your company details, write to us.

How do I cancel my subscription?

In your account on the website: Plan › Cancel subscription. From the app you get there with Settings › Account › Manage account. There you can also change your card, switch plans or see your invoices. You keep access until the end of the period you’ve already paid for and you won’t be charged again.

Can’t open the app? Write to us from your account’s email and we’ll cancel it for you.

I want a refund

You can ask for a full refund within 14 days of your first purchase, for any reason: write to [email protected] from the email you bought with. More details in our Refund Policy.

I have a discount code

On the payment page, click “Have a discount code?”, type it and press Apply before continuing. Each code is valid only for the plans it says.

The app

Requirements

Windows 10 (version 2004 or later) or Windows 11, 64-bit. It works with one or more screens and at any display scaling.

On how many PCs can I use it?

On up to 2 PCs at the same time with the same account. If both are in use and you sign in on a third one, the app offers “Use on this PC”: it replaces the PC you’ve gone longest without using. You can do that once every 7 days.

How do updates work?

Automatically. The app checks for new versions, downloads them and lets you know; you can install right away or later. It never updates while you’re in a game or watching something in full screen.

The app says my license has expired

That happens if your subscription was cancelled or a payment failed. Open your account to check your card, or choose a plan again. If you think it’s a mistake, write to us.

Windows says “Windows protected your PC”

Windows shows that warning with new apps it doesn’t know well yet. Click More info and then Run anyway. The installer only downloads Kaidan-Island from our server and checks that it’s the genuine app, signed by us, before installing it. You only see this the first time: updates install by themselves.

How do I uninstall it?

Windows Settings › Apps › Installed apps › Kaidan-Island › Uninstall. If you were using the Kaidan-Island taskbar, the Windows one comes back exactly as it was.
