Cookie Policy
1. What this policy covers
This cookie policy explains the cookies and similar tracking technologies that Porosimetry.com sets when you visit the site, what they are used for, and how to disable them. It is a companion document to the privacy policy, which describes the broader handling of personal information.
2. What cookies are
Cookies are small text files stored by your browser when you visit a website. They allow the site, or a third-party service the site uses, to remember information about your visit — for example to keep an authenticated session active, to count unique visits for analytics, or to attribute an ad impression for billing.
Similar technologies include local storage, session storage, web beacons, and pixel tags. References to "cookies" below cover all of these.
3. Categories of cookies in use
3.1 Strictly necessary
None at present. The site is a static reference and does not require authentication, shopping carts, or other features that depend on essential first-party cookies.
3.2 Analytics
The site uses Google Analytics 4 (measurement ID G-LX1TFZ6GEN) to count page views and broad usage patterns — for example, which articles are read most often. Google Analytics sets cookies in the _ga family on the visitor's browser.
| Cookie | Set by | Purpose | Typical lifespan |
|---|---|---|---|
_ga | Google Analytics | Distinguish unique visitors | Up to 2 years |
_ga_<id> | Google Analytics 4 | Persist session state for the property | Up to 2 years |
_gid | Google Analytics | Distinguish users (24-hour granularity) | 24 hours |
3.3 Advertising
The site does not currently display advertising and sets no advertising cookies.
Third-party vendors selected by Google may also set their own cookies for the same purposes. The current list of vendors that Google works with is published in Google's Ad Tech Providers reference and is updated by Google.
3.4 Functional / preference
The site does not currently set first-party preference cookies (no theme switcher, no language selector, no logged-in state). If this changes the table above will be updated.
4. Lawful basis (EEA, UK, Switzerland)
Strictly necessary cookies do not require consent. Analytics cookies are set under one of the following lawful bases, depending on your jurisdiction:
- Consent — in jurisdictions that require prior opt-in for non-essential cookies (most of the EEA, UK, and Switzerland), analytics cookies should only be set after consent. The site does not currently run a consent banner; you can block Google Analytics with the browser settings or opt-out add-on described below.
- Legitimate interest — in jurisdictions that allow opt-out for analytics, the legitimate interest is in measuring how the site is used to improve content quality.
5. How to control cookies
5.1 Browser controls
All major browsers let you view, block, or delete cookies. The relevant settings can usually be found under "Privacy" or "Site settings". Blocking all cookies will disable analytics on this site, and may break functionality on other sites you visit. Browser-level instructions:
5.2 Opting out of Google Analytics
You can prevent Google Analytics from collecting data about your visits by installing the Google Analytics Opt-Out Browser Add-On.
6. Changes to this policy
If the cookies set by the site change — for instance, if a new analytics or advertising vendor is added — this page will be updated and the "Last reviewed" date at the top will change. Material changes that affect what is collected or shared will be flagged in the privacy policy as well.
