Supporter key
What a supporter key is, what it does and what it does not do.
Last updated: 17 October 2026 Version: 1
The terms of sale apply to supporter keys in full. This page replaces sections 3, 4 and 5 of the terms of sale.
What it is
Our free products cost nothing and run in full, and they show a small supporter triangle. If you want to support the development, you can buy a supporter key.
- You choose one of the fixed amounts shown on the page before payment, currently €5, €10 or €20. The smallest amount is €5.
- It is a purchase, not a donation. The payment is not tax-deductible as a donation.
What it does
- It hides the supporter triangle.
- The supporter key does not expire. If you ask us to delete your data, the supporter key can no longer be activated, but computers that are already activated keep hiding the triangle, and versions released after a computer's last check show it again on that computer.
- It adds no other feature. Every free product works the same with or without a supporter key.
- One supporter key works in all free products of Irrvogel Interactive, and several free products on the same computer count as one computer.
Computers and activation
A supporter key works on up to two of your computers at the same time.
- A computer is activated with the supporter key. Activation needs an internet connection once, and again after you install a newer version. The computer can make it itself or, with offline activation, another device can, for example another computer or a phone. This does not apply once the switch-on file is published.
- When the computer happens to be online, the software checks the supporter key silently about once a day and right after you install a new version. If the check does not get through, the software tries again once an hour, and you can also start this check yourself. If there is no connection or the server cannot be reached, nothing changes.
- Only a signed message from our license server can make the supporter triangle show again, which happens when you removed the computer, when the supporter key was reset, or when the supporter key was blocked.
- You can deactivate a computer inside the software at any time and then activate another one, and there is no limit to this.
- A computer you no longer have can be removed remotely (remote removal), which is possible twice in any 30 days, and each use becomes available again 30 days later. How often you activate a computer is not limited, as long as no more than two are activated at the same time.
- A computer that someone else activated with your supporter key without your consent can be removed remotely as not yours ("That wasn't me"). This does not count as a remote removal, and we are told and check the supporter key. A computer that you activated yourself, or that was activated with your consent, stays yours in this sense, also after you sold it or gave it away. To remove such a computer, use a remote removal or write to support.
- A reset removes all computers of a supporter key at your request, for example when support helps you.
- A computer counts from its activation until it is deactivated in the software, removed remotely (also as not yours) or removed by a reset, even if the software no longer runs on it. After that you may use the supporter key on it again only after a new activation. If you cannot remove a computer you no longer have because both remote removals are used up, write to support@irrvogel.com and we reset the supporter key.
- If your supporter key is lost or someone else has it, you can get a replacement key once every 30 days. The old key stops working, but computers that are already activated keep working.
- Each new version of a free product needs a confirmation issued after the release date of that version. A computer that is online gets this confirmation automatically, and until then the new version shows the supporter triangle and otherwise works in full. A computer that is never online gets this confirmation through a new offline activation, which is free and does not use another of your two computers. This does not apply once the switch-on file is published.
- The supporter key is personal. You may not publish it or pass it on to others.
- You may block the software from the internet, for example with a firewall, and the software keeps working, but this does not extend your right to use the supporter key.
Without our license server
Activated computers keep working without the license server. While the license server is out of service, new activations, the confirmation for new versions and the license management page wait until it works again.
Every free product already contains a second way to activate a supporter key without the license server. This way stays switched off while the license server works and is switched on by a file that we sign (the switch-on file). Anyone may pass this file on, and the software checks our signature.
"Out of service" means that our license server does not answer requests from the internet in general, and a problem with the connection or network of a single customer does not count. If our license server is out of service for more than 60 days in a row, we publish this file within a further 30 days, and before we close our business or shut the license server down for good, we publish it first. From then on your supporter key works in every version of our free products without the license server, including versions that we publish after the file, and it works with the supporter key that was valid on the last day the license server worked. In this mode the software cannot count computers, but the limit of two computers still applies. From then on the software no longer contacts the license server.
The license management page, replacement keys and remote removal need the license server and are no longer available after a final shutdown.
Withdrawal and refunds
The rules on withdrawal, the three boxes before payment and refunds in the terms of sale apply (sections 8 and 9).
After a withdrawal or a full refund the supporter key is blocked and the triangle shows again, and nothing else changes in the software. If a chargeback ends in our favour, for example because you withdraw it, and the payment is restored, the supporter key continues and we lift the block.
Your right to use the supporter key ends after a withdrawal, after a full refund of the price (also a refund by Link), after a chargeback unless the payment is restored, after you end the contract because of a defect, and after a justified block. This applies even if a computer has not yet received the block, for example because it is offline or behind a firewall.
Blocking
A supporter key can be blocked for the same reasons and in the same way as a license key (withdrawn, refunded or misuse, see section 12 of the terms of sale). A blocked supporter key only means the triangle shows again.
Changes
We may change these supporter key terms for future purchases, and each version has a number, shown at the top. Your purchase keeps the version that applied when you bought, and a new version applies to your purchase only if you agree to it. Your statutory rights are not affected.
