Privacy

Calculations run in your browser. The values you enter are not transmitted, stored, or logged by us during ordinary calculation. The site sets no cookies and runs no third-party analytics.

The site does count how it is used, so we can see which calculators and pages are worth improving. Each page view (view), each percentile you get for an entry you made (result), and each link followed to another site (out) is sent as a small count to this site's own address. A count carries the page's path, the referring site's name and your country, and no cookie, no ID, no IP address and no amount, age or height you entered, and it is not linked to any other count. One click turns it off. The full list of what a count holds is below.

What is counted

Every page loads one small script of this site's own, /count.js. It sends short counts to this site's own address, /_c, and to nowhere else. There is no third-party analytics, tag manager, pixel or advertising script. Your browser enforces that part: the Content-Security-Policy served with every page allows connections to this origin alone, so a request to any outside origin is blocked. The embeddable calculators that other sites show in a frame do not load the counting script.

A count is sent when a page is viewed, when a calculator shows a percentile for an entry you made, and when you follow a link to another site or an email link. One count holds these fields and nothing else:

• Site. This site's name, whatsyourpercentile.com, so its counts can be told apart from other sites' counts.
• Copy. Whether the count came from whatsyourpercentile.com itself or from a preview copy of the site made while it is being changed.
• Kind of count. A page view, a calculator result, or a link followed to another site.
• Page. The address of the page, without anything after a question mark or a # sign, such as /income/. A shared result link keeps your entry after the # sign, and that part is never in a count.
• Start of a visit. For a page view, whether you arrived from another site or from nowhere (a typed address or a bookmark), rather than from a page on this site, a reload or the back button.
• Kind of referring site. For the first page of a visit only, which kind of site sent you: one name from a short fixed list of search engines, AI assistants and social sites, or direct, or other.
• Referring site. For the first page of a visit only, the name of the site that sent you, such as duckduckgo.com. Never the address of the page you came from, and never what you searched for.
• How the page was opened. For a page view, whether the browser followed a link, reloaded the page or used the back or forward button.
• Result or link. For a calculator result, one word, at most once per page view: networth when a net worth percentile is shown, income when a household income percentile is shown, earnings when an earnings percentile is shown, or height when a child's height percentile is shown. The word is all that is sent; the amount, age or height you entered and the percentile you got are not. For a link, the name of the site it leads to, or mailto for an email link.
• Format. The version number of this list of fields.
• Country. The two-letter code of the country the request came from, such as US, as the company that hosts this site already works it out to deliver the page, or XX when it cannot tell. Never a region, city, postal code or position.
• Time. When the count was received, added by the service that stores it.

A count holds no cookie or other identifier, no IP address, no network name, nothing finer than the country, no browser or device details, no screen size, no amount, age, height or other value you entered, no percentile you got, no text you type, and no full referring address. Nothing in one count ties it to another count or to you, so the counts add up to totals per page and per day and cannot be joined into a history of one person's visits.

Where counts are kept. Counts are written to Cloudflare Workers Analytics Engine, a storage service of the company that hosts this site, which keeps each count for three months. Daily totals may be kept longer. Counts are read only as totals.

Turning it off. One click turns counting off in this browser, and a second click turns it back on:

The switch writes one entry, count-off, holding 1, to this browser's local storage for this site. While it is there, /count.js sends nothing at all, on any page; the second click deletes it. Clearing this site's data in your browser deletes it too, and turns counting back on. If your browser sends Global Privacy Control or Do Not Track, the script sends nothing at all without any click. Blocking /count.js with a content blocker does the same, and with JavaScript off nothing is counted. Every calculator on the site works the same way without it.

Automated visitors. A count from software that names itself a bot or crawler is dropped, and so is a count from the hosting network our own test browsers run on: the code that receives a count compares the request's network number with that one network and stores neither. Other automated visits can still be counted, so the totals are approximate.

Hosting and server logs

The site is served by Cloudflare Pages. Like any web host, Cloudflare processes standard technical data (IP address, user agent, requested URL) to deliver pages, including the counts above, and to protect against abuse, subject to Cloudflare's privacy policy. Those server logs are outside our control. The code that receives a count reads the user agent only to drop self-declared bots, and stores neither the user agent nor the IP address. The values you enter are not in any request while you calculate.

When you choose to share

A result link contains the number or measurement you entered and its comparison settings. New links keep those values after the # in the address. Browsers do not send that part to the host, so the values are not in the HTTP request. Anyone who has the link can still read them, and the link may stay in browser, clipboard, or message history. Older links put entered values after a ? in the address, which makes them part of the HTTP request; avoid reusing those links.

The money-result PNG leaves out the entered amount unless you check “Put my number on the card”. The result link contains your value whether or not that box is checked.
