Terms of use

Last updated 29 October 2026.

The software

Qulok is desktop software for Windows, made by Sundry Mill and licensed to you for personal and commercial use on up to two computers you own or control. You may not redistribute modified copies under the Qulok name.

Plans and payment

Qulok is sold through Polar, our merchant of record, on two plans:

Monthly: USD 3 a month, starting with a 7 day free trial. A payment method is taken at checkout and nothing is charged during the trial. Unless you cancel before the trial ends, the subscription starts at the end of it and renews at USD 3 a month until you cancel. If you cancel during the trial you are not charged, and the licence key stops working when the trial ends. After a cancellation the key keeps working until the end of the period already paid for.
Lifetime: USD 19 once, for the life of the product, with every update included.

Prices may include tax depending on where you are; the checkout shows the total before you pay. Subscriptions are managed and cancelled from the link in your Polar receipt.

No warranty

Qulok changes window state and a few Windows settings on your behalf and restores them afterwards. It is provided as is. To the extent the law allows, we are not liable for any loss arising from its use, including a setting that was not restored. If something is not restored, relaunching Qulok runs the restore again, and every setting it touches can also be changed back by hand in Windows Settings.
