HELIOS
Customer guide
How payment, renewal, cancellation, downloads, installation, activation and support work.
Choose one plan, create or sign in to your HELIOS account, review the legal documents and continue to Stripe’s secure checkout. HELIOS does not receive or store your full card number.
After Stripe confirms payment, your order, licence and download appear under Purchases. Keep the payment receipt from Stripe for your records.
Monthly and yearly plans renew automatically at the end of each paid period unless cancelled. The next payment date appears in Purchases.
To stop renewal, open Purchases, choose Cancel subscription, and confirm your password. No further renewal is taken and access continues until the displayed paid-period end.
If a renewal fails, the account shows a warning while Stripe retries. When online billing management is available, choose Update payment details to open Stripe’s secure portal. Otherwise contact support. Never email card details.
Sign in, open Purchases and choose Download HELIOS. Download links are private and expire quickly; return to Purchases to generate a new link when needed.
Open the downloaded release package and follow its included installer and release instructions. On first launch, sign in with the account used for purchase and enter the licence key shown in Purchases. Keep the key private.
If your access has expired or been revoked, licence reveal, new downloads and application access are blocked. Restart an eligible subscription from Purchases to restore access.
Use Forgot your password? on the sign-in screen. Verification and reset messages may take a few minutes; check the spam folder before requesting another.
From Your details, choose Request account deletion and confirm your password. HELIOS reviews the verified request and removes eligible data while retaining only records required by law or needed for tax, fraud prevention, disputes and security.
Email support@helios-nt.com from the address on your HELIOS account. Include the problem, approximate purchase date, plan, operating system, app version and any customer-safe error message.
Do not send your password, full licence key, authentication token, complete card number or security code. Support may ask you to verify account ownership before discussing an order.
