Privacy Policy

Last updated: September 2026.

We keep this simple, just like the rest of the site.

What we collect

• Analytics: we use Google Analytics to see which pages people visit, so we can improve the site. This is aggregated and anonymous.
• No accounts: the calculators run entirely in your browser. Nothing you enter, your pump, your CGM, your trip dates, is sent to us or stored anywhere.

Cookies

Google Analytics sets cookies to measure visits. Amazon affiliate links on some pages may set cookies so Amazon can credit us if you buy something, that's how the site stays free.

What we never do

We never sell your data, because we don't collect data that could identify you in the first place.
