Terms of Service
Plain terms for a one-machine licence. If something here is unclear, email us before you buy and we will answer it.
What you are buying
A Kurm Optimizer licence is a right to use the software on one specific computer. It is not a sale of the software itself, and it is not a subscription that renews - nothing is charged again automatically.
Normal and Maximum licences run for 30 days from the day the key is issued. A Forever licence does not expire. The tier you bought determines which panels unlock; the current split is listed on the pricing page and in your account.
Machine binding
Your key is generated from the Machine ID you supply at checkout. The binding is part of the key's mathematics, not a check performed afterwards, which means the key cannot be made to work on a different computer by us or by anyone else.
If you replace your motherboard, CPU, or reinstall Windows in a way that changes your Machine ID, your existing key will stop validating. Contact us with your order reference and we will re-issue a key for the new Machine ID at no charge for the remainder of an unexpired licence.
Because a key is worthless on any machine but yours, we do not restrict how you store it. We do ask that you do not publish it, since doing so tells others what your machine's fingerprint is.
What the software does to your computer
Kurm Optimizer changes Windows settings. Depending on the tier and the panels you use, that can include registry values, service startup states, power and scheduling settings, network stack parameters, display colour pipelines, and - on the Maximum tier - processor and memory clock and voltage targets.
Overclocking carries real risk. Running hardware outside its rated clocks or voltages can cause instability, data loss, shortened component life, or permanent damage, and typically voids the hardware manufacturer's warranty. The Overclock panel is opt-in and is not applied unless you choose to apply it.
The software creates restore points before registry changes and provides a documented way to revert its tweaks. You remain responsible for maintaining your own backups.
Refunds
If your key has not been activated, you may request a full refund within 14 days of purchase for any reason. Email us with your order reference and we will process it.
Once a key has been activated on your machine, we refund only where the software does not work as described and we cannot resolve the problem with you. We will always try to fix it first.
If you are a consumer in the UK or EU, these terms do not affect your statutory rights, including the statutory right to cancel a digital purchase. Where you have asked for immediate delivery of the key and it has been delivered, the statutory cancellation right may no longer apply.
Acceptable use
Do not resell, sublicense, or redistribute keys. Do not attempt to extract the key-signing secret, generate keys yourself, or circumvent the licence check. Do not use the software on a machine you are not authorised to modify.
We may revoke a licence without refund if it was obtained fraudulently, through a reversed or disputed payment, or in breach of this section.
Liability
The software is provided as is. To the maximum extent permitted by law we exclude liability for indirect or consequential loss, lost data, and lost profits. Nothing here excludes liability for death or personal injury caused by negligence, for fraud, or for anything else that cannot lawfully be excluded.
Where liability cannot be excluded, it is limited to the amount you paid for the licence in question.
Support and response time
We answer support email within one business day. Activation problems - a key that will not validate, a Machine ID that has changed - are treated as priority and are usually resolved the same day.
Changes to these terms
These terms are versioned. Your order records the version you agreed to, and a later change does not alter the terms of a purchase already made. Material changes are reflected in a new version number and effective date at the top of this page.
