Terms
Last updated 13 November 2026
Short, because the page is a calculator that runs in your browser.
Using the page
You may use this page and the CSS it produces for anything you like, personal or commercial, at no cost. No account is needed and none is offered. You do not have to credit us, though a link is welcome.
The values are a starting point
The export is valid CSS, and how it looks depends on the surface, the display, the brightness of the room and the eyes in front of it. Check the result in the browser and on the device where it will be used, and check the contrast of any text over a glass panel yourself.
Do not rely on this page where a visual mistake costs money, health or safety. It is a bench, not a design review.
What you make stays yours
The values you set and the CSS you copy are yours. We claim no licence over them, because we never receive them. The page, its text, its design and its code belong to Pikkola.
No warranty
The page is provided as it is, without warranty of any kind, express or implied, including fitness for a particular purpose. To the extent the law allows, Pikkola is not liable for any loss arising from use of the page.
Fair use
Please do not use the page to attack anything, to disguise traffic, or to present it as a paid service of your own. Embedding a link is fine. Copying the whole page and hosting it as your product is not.
Changes and availability
The page may change or be withdrawn at any time without notice. Terms may change; the date at the top is the record. Continuing to use the page after a change means the new terms apply.
Law
These terms are governed by the laws of the Republic of Korea, without regard to conflict of law rules. Disputes belong to the courts of Seoul.
