Cookie policy
Last updated: September 2026. This page lists everything this site stores in your browser and why.
Local storage (not a cookie, but similar)
This site saves the height, unit and optional child name you enter in your browser’s local storage, so the checker remembers them the next time you visit on the same device. It also remembers your choice from the cookie banner below. None of this is sent to this site’s server.
Advertising cookies
This site runs Google AdSense. Once you accept ads via the banner shown on your first visit — or if you’re a returning visitor who has already accepted — Google and its advertising partners may set cookies or use similar technologies in your browser to serve ads, limit how often you see the same ad, measure ad performance, and, where permitted, personalise ads based on your browsing activity on this and other sites.
If you choose “Essential only”, or haven’t made a choice yet, ads are still shown but requested as non-personalised, using Google’s standard requestNonPersonalizedAds setting.
You can change your choice at any time by clearing this site’s data in your browser settings (the banner will reappear on your next visit), and you can review or reset Google’s ad personalisation for your Google account directly at adssettings.google.com.
How Google uses this data

Managing cookies and local storage
You can clear cookies and local storage for this site at any time through your browser’s settings, or use browser-level controls such as blocking third-party cookies if you’d prefer not to receive advertising cookies at all. Doing so may reset your saved height and reshow the consent banner.
See the Privacy Policy for more on what information this site does and doesn’t collect.
