Cookie Policy

1. What Are Cookies?

Cookies are small text files that a website stores on your browser or device when you visit. They are widely used to make websites work more efficiently and to provide information to website owners.

We also use localStorage — a similar browser-based technology that stores data locally on your device. Unlike cookies, localStorage data is not sent to our servers with each request.

2. How We Use Cookies and Local Storage

MedicalCalculators.net uses the following types:

3. What We Do NOT Use

• No advertising or targeting cookies
• No social media tracking pixels
• No fingerprinting or cross-site tracking
• No third-party remarketing cookies
• We do not sell or share cookie data for commercial purposes

4. Essential Cookies and localStorage

Some cookies and browser storage are strictly necessary for the site to function or to record your privacy preferences. These do not require your consent and cannot be disabled without affecting site functionality:

• Consent record (mc_consent) — stores your accept/reject decision for analytics cookies
• Recently used calculators (mc_recent) — stores a list of calculators you have visited, displayed on the homepage for convenience. This data never leaves your device.

Because mc_recent is stored solely in your browser's localStorage and is never transmitted to our servers, it does not constitute personal data processing by us under UK/EU GDPR.

5. Analytics Cookies

With your consent, we use Google Analytics to collect anonymised usage data. This helps us understand:

• Which calculators are most frequently used
• General geographic regions of our users (country/region level only)
• Device types (mobile, desktop, tablet)
• How visitors navigate between pages
• Session duration and bounce rates

We have enabled IP anonymisation in Google Analytics, meaning your full IP address is never stored. Google Analytics data is processed by Google LLC. See Google's Privacy Policy.

If you decline analytics cookies via our consent banner, Google Analytics will not be loaded.

6. Your Consent Choices

When you first visit MedicalCalculators.net, a cookie consent banner will appear. You can:

• Accept — enables analytics cookies
• Reject — only essential functions are active; no analytics cookies are set

Your choice is saved in your browser's localStorage. You can change your preference at any time by clearing your browser's localStorage or site data (see your browser's privacy settings).

7. How to Control Cookies in Your Browser

You can manage or delete cookies directly through your browser settings. Instructions for common browsers:

• Google Chrome
• Mozilla Firefox
• Apple Safari
• Microsoft Edge

Note: disabling all cookies may affect how some websites function. Our calculators will continue to work without cookies — you will simply not have the recently-used history on the homepage.

You can also opt out of Google Analytics tracking across all sites using the Google Analytics Opt-out Browser Add-on.

8. Updates to This Policy

We may update this Cookie Policy if we change the tools or cookies we use. The "Last updated" date at the top will reflect any changes. Continued use of the site after updates constitutes acceptance.
