Privacy policy
The short version
There are no accounts, no sign-up and no login. Nothing you type into a calculator is stored or transmitted.
- This site sets no cookies of its own.
- This site runs no analytics or tracking scripts.
- Calculations happen in your browser. The numbers you enter are not sent to us.
- One small signal is sent when you first change a control on a calculator — which page it was, and nothing else. See "The one signal this site sends" below.
- No advertising is served on this site at present. If that changes, this page changes first — see "If this changes" below.
What is processed
Like any website, this one is reached over the internet, and the request has to pass through a content delivery network before a page can be returned. That network processes the ordinary technical data of a web request — the requested address, an IP address, a user agent, and a timestamp — in order to serve the page and to absorb abusive traffic. This is how the page reaches you at all; it is not a profile, and it is not used to build one.
We do not maintain a separate store of that data. There is no analytics product attached to this site, no session recording, no heatmap, and no advertising pixel. The one thing this site does send is described in the next section, and it is the only outbound request any page makes.
The one signal this site sends
The calculators run in your browser, so the site has no other way to tell whether a page was used rather than merely loaded. Each calculator therefore sends one small signal the first time you change a control on the page: which calculator it was. That is the whole payload — the name of the page. It is sent once per page, at most, and it carries no value you entered, no identifier for you or your device, and nothing that links this page to any other page you visit.
What it is for: an answer to whether a calculator works for anyone at all. A page that is visited and never used looks identical to a page nobody has found yet, and those two call for opposite responses. This signal is the only thing that separates them.
What you type
The values you enter into a calculator stay on your device. The formula and the arithmetic are part of the page you downloaded, so the answer is computed locally and never has to leave your browser to exist. If you are offline after the page loads, the calculator still works — which is the simplest proof of the claim.
Advertising and third parties
No advertising is served on this site at present. It may be introduced later; the section below describes what applies when it is.
Advertising and third-party cookies
No advertising is served on this site at present. This section describes what applies when it is, and is required to be here before then.
This site may display advertising served by third-party vendors, including Google. Those vendors are the ones who place and read cookies on your browser when an ad is shown — this site does not do that itself, and has no access to what they store.
Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this website or other websites. Google's use of advertising cookies enables it and its partners to serve ads to you based on your visit to this site and/or other sites on the internet.
These vendors may also use web beacons, and may collect the IP address from which a request was made, in the course of serving an ad and measuring it.
You can opt out of personalised advertising by visiting Google's Ads Settings. You can also opt out of some third-party vendors' use of cookies for personalised advertising at aboutads.info.
Source: Google Advertising Policies — Privacy disclosures — the policy this is restated from. Read 2026-11-04; due to be re-read by 2027-02-04. This section is a restatement of that document, not a description of anything this site does.
If this changes
This page is generated from the same description of the site that the build itself uses, and the build refuses to publish a privacy page whose central claims do not hold of the artifact it is publishing. So a change to what this site collects cannot land without this page changing in the same build. The "last updated" date on each page reflects when its text last changed.
