Cookie policy
What is stored in your browser when you use CALCSLIP, who stores it, and how to refuse it.
Last updated November 10, 2026
In short
The calculators themselves need no cookies. Two things are kept in your browser's local storage to make the site work the way you left it, and Google sets cookies for analytics and advertising. In the European Economic Area, the United Kingdom and Switzerland those Google cookies stay off until you agree to them.
Stored by CALCSLIP (local storage, not cookies)
- cv.currency: the currency you picked, so the next calculator opens in it. Kept until you clear your browser data.
- cv.recent: your last few calculations (the calculator, its result and its link), shown on the home page. Clear it there with one click, or by clearing your browser data.
Neither leaves your device. If your browser blocks storage, the calculators still work; they just will not remember these choices.
Analytics: Google Analytics 4
We use Google Analytics to count visits and learn which calculators are used. It sets first-party cookies named _ga and _ga_<ID>, kept for up to two years, to tell a returning visitor from a new one. We send it the page path only, never the part of the address that holds the numbers you typed. Google's explanation is at policies.google.com/technologies/cookies.
Advertising: Google AdSense
CALCSLIP is paid for by ads served by Google. Third-party vendors, including Google, use cookies to serve ads based on your previous visits to this and other websites. Google's advertising cookies (such as __gads, __gpi and cookies on doubleclick.net) let Google and its partners show ads based on those visits, limit how often you see the same ad, and measure results.
You can turn off personalized advertising at Google Ads Settings, and opt out of other vendors' personalized ads at aboutads.info. Non-personalized ads still use cookies for frequency capping and fraud prevention.
Your consent
Visitors in the European Economic Area, the United Kingdom and Switzerland see a consent message from a Google-certified consent platform. Until you agree, Google Analytics and advertising run in a cookieless mode (Google Consent Mode, with storage denied by default). You can change your choice at any time from the privacy link that the consent message adds to the page.
Turning cookies off in your browser
Every browser lets you block or delete cookies and site data in its privacy settings. Blocking them does not stop any calculator from working.
