Privacy

The short version: the numbers you type stay in your browser. The site sets no cookies, doesn't use Google Analytics and shows no ads.

Your calculations

Every calculator runs entirely in your browser. The amounts, volumes and doses you enter aren't sent to this site or anyone else, and nothing is saved when you leave the page.

Two exceptions are under your control:

• Copy result puts a line of text and a link on your clipboard. The link carries the numbers you entered (for example ?vial=10&water=2&dose=250) so it opens with the same result. Anyone you share it with sees those numbers, and opening the link sends them to the web server like any web address.
• If you open a page from such a link, the numbers come from the link, not from anything stored.

Cookies, analytics and ads

The site sets no cookies and loads nothing from other websites: no Google Analytics, no advertising, no tracking pixels, no third-party fonts. Visits are counted with Vercel Web Analytics, which sets no cookies, doesn't track people across sites, and only reports totals such as page views, referrers, country and device type. If that changes, this page will be updated first.

Hosting

The site is hosted by Vercel. Like any web host, Vercel's servers receive standard request information when you visit, such as your IP address, browser type and the address requested, and may keep it in logs for security and operations. See Vercel's privacy policy for how long and why.
