COMMON QUESTIONS
Avoid duplicate payments and account confusion.
Where do I start?
Install NurViewer for free and sign in. Choose Standard or Pro in Settings → Purchase & licence. The app opens a short-lived account-bound payment link. This information page does not collect payment.
Is this a subscription?
Current Standard and Pro offers are one-time purchases with no automatic renewal. Free has no trial expiry. Compare capabilities first; Paddle shows final currency, tax and total.
How do I upgrade Standard?
Use the upgrade option in the same NurViewer account. Eligible customers can pay the difference for Pro; avoid purchasing a second full licence with another account.
Why does the app still say Free?
Return to the same account that started the purchase and refresh its licence. Wallet authorisation can precede final capture and server verification. A browser success message alone does not establish paid access.
What if checkout is slow or a wallet is missing?
Use a desktop system browser, your real billing country and an eligible currency/device. See the connection guidance below. If already charged, check your receipt and licence before submitting another order.
Do I repay after changing devices?
Usually no. Sign in to the original account, manage devices and refresh the licence. Plan-specific device and simultaneous-use limits still apply.
Where are receipts, refunds and support?
Keep the transaction reference in your Paddle receipt. Existing refund policies and applicable rules govern requests. Send support the reference, app version and failing step, never card numbers, passwords, verification codes or licence tokens.
CONNECTION TROUBLE
Identify the step that is slow.
The website, Microsoft/Google sign-in and Paddle/payment-provider pages use different services. Try another trusted network or supported desktop browser; check date/time and keep security verification enabled. Contact support with the failing service and approximate time. A faster website cannot guarantee a third-party login or payment connection.
