Refund policy

Refunds

OmniDICOM is sold with a 14-day free trial of the complete Professional feature set, so you can establish that it works for you before any money changes hands.

The trial comes first

You can start with a 14-day trial of full Professional, with no card and no account. Nothing is withheld during it. If OmniDICOM cannot open your studies, cannot talk to your PACS, or does not do what you need, you will know before you buy. If 14 days is not enough to evaluate it — a team pilot, an institutional review — write to us and we will extend it.

If you still want a refund

We will refund a purchase in full, for any reason, within 30 days of the payment date. Write to contact@omnidicom.com from the address you bought with and tell us the order reference. You do not have to give a reason.

• Refunds are issued to the original payment method.
• Processing is handled by Paddle, our reseller and merchant of record, and usually takes 5–10 business days to appear on a statement.
• The licence is deactivated when the refund is issued.
• A refund of unused Basic time when you upgrade to Professional does not deactivate your licence key, which carries on as Professional.

Renewals

Subscriptions renew automatically. If a renewal takes you by surprise, tell us within 30 days of the charge and we will refund it in full, for any reason. You can turn off automatic renewal at any time from the link on your receipt.

Cancelling a subscription

You can cancel at any time; the licence keeps working until the end of the period you have already paid for, and is not renewed after that. Cancelling is not the same as a refund — it stops the next payment rather than returning the last one. An upgrade to Professional started in OmniDICOM, paid with the email address you bought Basic with, is the exception: Basic ends straight away and its unused part is refunded, because your licence carries on as Professional.

Upgrading from Basic to Professional

Upgrading moves your existing licence key to Professional as soon as payment completes. We then cancel your Basic subscription and refund the unused part of your current Basic billing period to your original payment method. Your key and activated computer stay the same.

• Start the upgrade from OmniDICOM. It opens checkout with Professional selected, on the same billing period as your Basic subscription, and shows “How the upgrade works” above the payment button with all of this before you pay. Only a checkout that shows it is an upgrade.
• An upgrade link is personal: OmniDICOM makes it for your Basic licence, so do not pass it on. The upgrade only applies when you pay with the same email address as your Basic purchase. Otherwise you receive a separate Professional licence key, and Basic stays active.
• The Professional price is charged in full at checkout. The unused Basic amount is refunded afterwards; it is not taken off that charge.
• The unused part is the share of your current Basic billing period that is still to run when the upgrade completes, applied to what you paid for that period. Nothing is refunded for a period you did not pay for, or when the amount is smaller than the smallest unit of your currency.
• The refund follows Paddle's processing times, like any other refund on this page. It does not deactivate your licence key, which carries on as Professional.
• We email you a confirmation that your licence is now Professional, with any refund due.
• If, after you pay through that checkout, we cannot move your licence (for example because the link was already paid for, Basic had already ended, or you paid with a different email address), you still get Professional: we email you a new Professional licence key as for any purchase. If you still have an active Basic subscription, it is not cancelled automatically: cancel it using the link on its Paddle receipt, which stops renewal but refunds nothing, or write to us from the email address you bought Basic with and we will cancel it and refund its unused part. A Professional payment you did not need, such as a second payment for the same upgrade, can be refunded in full as described above.
• The Professional payment has the same 30-day refund window as any other payment. Once Basic has been cancelled, refunding it deactivates your licence key, as any refund does, and does not bring Basic back: Basic was already cancelled and its unused part refunded. To go back to Basic, buy it again; it comes with a new key. If that refund is made before we have cancelled Basic, the upgrade is undone instead: your key goes back to Basic, and Basic carries on as before.

Buying Professional without upgrading. A Professional purchase through a checkout that does not show “How the upgrade works” — from the plans on this website, or from a version of OmniDICOM that could not upgrade your licence — is a separate subscription with its own new licence key. Your Basic subscription is not changed: it keeps renewing until you cancel it using the link on its Paddle receipt, and nothing is refunded automatically. A Basic payment made in the last 30 days can still be refunded in full, as described above.

What we do not refund

• Periods you have already used, beyond the refund window above.
• Academic licences, which are issued free of charge.
