This site sets no cookies on an ordinary visit.
No advertising pixels and no cross-site tracking. The calculators run entirely in your browser and keep nothing between visits — reload the page and every field is back to its default.
We do count page views, using Vercel Analytics. It records which pages were opened and roughly where in the world from, and it does it without cookies and without identifying you. There is no profile, nothing that follows you between visits, and nothing that can be tied back to a person.
One cookie exists and only for people who sign in: the session that keeps you logged in. It is strictly necessary for a login to work, which is why it needs no consent, and it is set only after you ask to sign in.
That is why you have not been shown a cookie banner. Consent is required for cookies that track you, and there are none.
When accounts and a cart are added, a login session cookie and a cart cookie become necessary for those features to work. Both are strictly functional. This page will be updated before either ships, and if anything non-essential is ever added, you will be asked first.
Questions about data generally are answered on the privacy page.
