Calculators
Everything you type into a calculator stays in your browser. Nothing is sent to us, stored, or logged. Reload the page and it is gone.
If you request the printable dose chart, we store your email address with our email provider to send it and to send occasional updates when a page or an FDA status changes. Every email has an unsubscribe link, and unsubscribing deletes the address from our list.
Analytics
We use privacy-respecting page analytics to count visits and see which pages are read. We do not use advertising identifiers or sell data. If display advertising is enabled, the ad network's own policy applies to its scripts and is linked here when that happens.
Affiliate links
Clicking a labeled affiliate link may set a cookie on the provider's site so that a referral can be credited. That cookie belongs to the provider and is governed by their privacy policy.
