Cookie policy
This site sets no cookies of its own. What follows is what the third parties that fund it can set, and how to control them.
Last updated 30 August 2026
Calcumetryx itself stores nothing in a cookie. No login, no account, no first-party tracker. A calculation you share puts its values in the page’s URL fragment, which stays in your browser and is never sent to a server.
What a cookie is
A small piece of data a site asks your browser to store, then reads back on a later visit — used here only by the two third-party services below, never by Calcumetryx directly.
Cookies this site uses
Calcumetryx is funded by advertising and measures which calculators get used with Google Analytics. Both are built on Google infrastructure and both can set the cookies below in your browser.
Analytics — Google Analytics 4
| Cookie | Set by | Purpose | Typical duration |
|---|---|---|---|
| _ga | Distinguishes one visitor from another | 2 years | |
| _ga_[container id] | Persists session state for GA4 | 2 years |
We configure Analytics to anonymise IP addresses. The events it records are aggregate — “a calculator was viewed”, “a result was generated” — and never include the numbers you typed into a calculator. Full detail is in the privacy policy.
Advertising — Google AdSense
| Cookie | Set by | Purpose | Typical duration |
|---|---|---|---|
| __gads / __gpi | Frequency-capping and basic ad measurement | up to 13 months | |
| IDE, test_cookie and similar | Google / ad partners | Ad personalisation and delivery, where permitted | varies by partner, typically up to 24 months |
Google and its advertising partners may use these cookies to serve ads based on your visits to this and other sites. Ad slots on this site are placed only below or between content sections — never inside a calculator’s controls, and never between an input and its result.
Managing cookies
You can opt out of personalised advertising at Google Ads Settings, opt out of third-party vendor cookies generally at aboutads.info (youronlinechoices.eu for EU visitors), or block cookies entirely in your browser’s settings. Blocking analytics and advertising cookies does not break any calculator — every tool runs the same either way.
