Cookie Policy
Last updated: July 10, 2026
This page explains, specifically, what cookies and browser storage Calixo uses. For the broader picture of what information we do and don't collect, see our Privacy Policy.
What's a cookie, and what's local storage?
A cookie is a small piece of data a website asks your browser to store and send back on future visits. Local storage is similar but stays entirely on your device and is never automatically sent to any server — that's the mechanism most of Calixo's own features actually use, which is why our footprint here is smaller than most sites.
Cookies/storage we set directly
| Key | Purpose | Type |
|---|---|---|
| calixo-theme | Remembers your light/dark mode preference | Local storage, functional |
| calixo-favorites | Calculators you've bookmarked | Local storage, functional |
| calixo-history | Recently viewed calculators | Local storage, functional |
| calixo-scenarios | Named input snapshots you've saved | Local storage, functional |
| calixo-stats | Visit counts per category, powering Library badges | Local storage, functional |
| calixo-ad-consent | Your accept/decline choice in the consent banner | Local storage, functional |
| calixo-sticky-ad-dismissed | Whether you've closed the mobile sticky ad | Local storage, functional |
| calixo-install-dismissed | Whether you've dismissed the "install app" prompt | Local storage, functional |
None of these are cookies in the strict HTTP sense — they're all browser local storage, meaning they're never transmitted to our (or anyone else's) servers automatically. They exist purely so the Site remembers your preferences between visits.
Google Analytics cookies
| Cookie | Purpose | Typical duration |
|---|---|---|
| _ga | Distinguishes unique visitors for aggregate traffic reporting | 2 years |
| _ga_<container-id> | Persists session state for Google Analytics 4 property tracking | 2 years |
Unlike the local-storage keys above, these are genuine HTTP cookies set by Google's own domain, used to measure aggregate site traffic (which pages are popular, how visitors typically navigate) — not to identify you personally. See Privacy Policy → Analytics for how to opt out.
Third-party advertising cookies
When advertising is active on the Site (via Google AdSense), Google and its advertising partners may set their own cookies — including the DoubleClick DART cookie — to serve and measure ads, including based on your visits to this and other sites. These are genuine HTTP cookies set by Google's domains, not by us directly, and only load after you accept the consent banner. Google's own documentation covers exactly what these cookies do: policies.google.com/technologies/ads.
How to control or clear cookies
You can accept or decline advertising cookies via the consent banner shown on your first visit — declining doesn't affect any calculator's functionality. You can clear everything listed above at any time by clearing your browser's site data for calixo.cloud, or from the "Your Library" page on the Site. Every major browser also lets you block cookies entirely or per-site:
