Privacy Policy

Last updated: October 22, 2026

GLPKit is a static website with no accounts and no forms that collect personal information. This policy explains, in plain language, the small amount of data involved in running it.

Calculator inputs stay in your browser

Every calculator on GLPKit runs entirely on your device, in your web browser. The numbers you type, such as your weight, are used only to show your result on the page. They are not sent to a server, not stored, and not shared with anyone.

Anonymous analytics

Like most websites, GLPKit may use a privacy respecting analytics service to understand which pages and tools are useful. Analytics data is aggregated and anonymous: pages visited, approximate country, device type and how visitors arrived. It is used only to improve the site. It is not used to identify you, and it is never combined with your calculator inputs, which never leave your browser in the first place.

Cookies

GLPKit does not set advertising cookies. If analytics or embedded third party services are used, they may set limited cookies needed for their operation. You can block or clear cookies in your browser settings at any time, and the tools will still work.

Advertising and affiliate links

If the site later carries advertising or affiliate links, those partners may use their own cookies under their own privacy policies, and outbound clicks to retailer or provider sites are governed by those sites. Any such links will be clearly part of the page content, and using them is always your choice.

What we never do

• We never ask for an account, password or payment details.
• We never collect health information. Calculator inputs never leave your device.
• We never sell or rent personal data, because we do not hold any.

Changes to this policy

If this policy changes, the updated version will be posted on this page with a new date at the top. Material changes, such as adding a new category of data collection, will be described clearly rather than buried in legal language.

Questions

If you have a question about privacy on GLPKit, you can reach the team through the contact details published on the site. Please do not send personal health information by email.
