Privacy Policy

Nothing you type into the calculators ever leaves your browser. The calculators run entirely on your device — vial weights, doses, and compound names are never transmitted to us and never stored anywhere.

We have no sign-up, no login, no accounts, and no contact forms. The only way to send us personal information is to email us, and then we hold only what you chose to put in the email.

We use Cloudflare Web Analytics to count page views and see which pages people find useful. We chose it specifically because it is privacy-preserving: it sets no cookies, uses no localStorage, no device fingerprinting, and no cross-site identifiers. It cannot follow you to other websites and it does not build a profile of you.

It reports aggregate figures only — page URL, referrer, and general country, browser, and device type. We cannot single you out from that data, and it is not sold, shared, or used for advertising. Cloudflare processes it as our provider; see Cloudflare's own privacy documentation for their handling. Because no cookies or identifiers are set, no consent banner is required.

We set no cookies. There is nothing here for you to opt out of.

When you click a partner link we send you through a page on this site (a /go/ address) and then on to the seller. That hop lets us count clicks in the same aggregate analytics described above; it sets nothing on your device.

Once you land on the seller's site you are subject to their privacy policy, not ours. They will typically record that the visit came from us so they can attribute a commission, and they may set their own cookies. We never receive your name, email, address, order contents, or payment details from them — only aggregate counts of referred orders. See the Affiliate Disclosure.

The site is a set of static files hosted on Cloudflare Pages. Cloudflare processes server logs, including IP addresses, as part of delivering and protecting the site — standard for any web host, and retained by them on their schedule rather than ours.

Depending on where you live you may have rights to access, correct, or delete personal data an operator holds about you. In practice we hold none — there are no accounts and the analytics cannot be traced back to an individual — so there is generally nothing for us to retrieve or erase. If you have emailed us and want that correspondence deleted, ask and we will delete it.

This site is not directed at children and we do not knowingly collect information from anyone under 16.

If this policy changes materially the date at the top of the page will change. Questions or requests: crocodileburpcloth@proton.me.
