Privacy policy
Last updated 2026-07-26
Who runs this site
PharmCalc is operated as an independent project from Texas, United States. For any privacy question, or to make a request about your data, email [email protected].
What we do not collect
The values you enter into any calculator are processed entirely in your browser using JavaScript. They are never transmitted to us, never stored on a server, and never logged. There is no sign-up, no login, and no user account. We hold no database of anything you have calculated.
We do not use analytics, we do not fingerprint devices, and we do not run session recording of any kind.
What is stored on your own device
PharmCalc uses your browser's local storage to remember a few preferences between visits. This information stays on your device, is never sent anywhere, and you can erase it at any time from the About page or by clearing your browser data.
| Stored | Why |
|---|---|
| Theme and display density | To keep the interface as you set it |
| Preferred units | So you need not reselect kg or lb each visit |
| Decimal-place preference | Rounding display setting |
| Favourites | The calculators you have pinned |
| Last 20 calculations | Shown on the home page for quick return. Includes the values you entered |
Server logs
Like every website, PharmCalc is served by a hosting provider (Cloudflare) which keeps standard request logs for security and reliability. These typically record the IP address making the request, the time, the page requested, and the browser user-agent string. We do not use these logs to build any profile of you, and we do not combine them with anything else. They are held by the hosting provider under its own retention policy.
Advertising and cookies
This site currently displays no advertising and sets no advertising or tracking cookies. If that changes, this policy will be updated before any ad code is loaded, and visitors in the European Economic Area, the United Kingdom and Switzerland will be asked for consent through a Google-certified consent management platform before any advertising cookie is set.

Health information
PharmCalc provides no field for a patient name or any other identifier, and none should be improvised. Because calculator inputs are never transmitted or stored by us, PharmCalc does not create, receive, maintain, or transmit protected health information on behalf of any covered entity under HIPAA. This describes how the site behaves; it is not legal advice, and an organisation deploying or relying on PharmCalc should reach its own compliance determination.
Your rights
Because we hold no personal data about you, there is nothing for us to access, correct, export, or delete on your behalf. Everything PharmCalc stores is on your own device and entirely under your control.
Texas residents. Under the Texas Data Privacy and Security Act you have rights to confirm, access, correct, delete, and obtain a copy of personal data a controller holds about you, and to opt out of targeted advertising, sale of personal data, and certain profiling.
California residents. Under the CCPA as amended by the CPRA you have rights to know, delete, correct, and to opt out of the sale or sharing of personal information.
EEA and UK residents. Under the GDPR and UK GDPR you have rights of access, rectification, erasure, restriction, portability, and objection.
We do not sell or share personal information, and we do not use it for cross-context behavioural advertising ourselves. To exercise any right, or to ask what we hold, email [email protected].
Children
PharmCalc is intended for pharmacists, pharmacy students, and other healthcare professionals. It is not directed at children, and we do not knowingly collect information from anyone under 13.
Changes to this policy
If this policy changes materially — in particular if advertising or any analytics were introduced — the updated date at the top of this page will change and the new terms will be published here before the change takes effect.
