THE SHORT VERSION
There are no accounts and no sign-up. Everything you type into a calculator is worked out inside your own browser and is never sent to us. We use Google Analytics to understand which calculators people find useful, which sets cookies — section 8 explains how to opt out. We run no advertising scripts. Apart from that, the only information that reaches our servers is what you deliberately send — a thumbs up or down, an error report, or a search term. This summary is here for convenience; the sections below are the actual policy.
EagleCalculator (eaglecalculator.com, and the short domain eaglecalc.com) is operated by Chetan Kumbhar, sole proprietor, based in Goa, India. In this policy “we”, “us” and “our” refer to that operator, and “you” refers to anyone visiting the site.
For any question about this policy or your data, write to eaglecalculator@gmail.com. We are the party responsible for deciding how the limited data described below is handled.
Stating this plainly, because it covers most of what people worry about:
Sections 7 and 8 describe what would change if advertising or analytics are introduced later. This policy will be updated, and the date at the top revised, before that happens.
Every calculation runs locally, in the browser on your device. Salaries, ages, weights, loan amounts, medical figures and every other number you enter are used to render the result on your screen and are not transmitted to us, not written to our database, and not visible to us at any point.
One consequence worth understanding: if you use the share feature, the link you generate may contain the values you entered so that the recipient sees the same result. Anyone you send that link to can therefore see those numbers. That is your choice to make each time, and nothing is shared unless you press the button.
The site keeps a small amount of information in your browser’s local storage. This never leaves your device, is not transmitted to us, and is not linked to any identity.
All of it can be erased at any time by clearing site data for eaglecalculator.com in your browser settings, and it is removed automatically if you clear your browsing history. Because this storage is strictly functional and is not used to profile or track you across other websites, no consent is required for it.
Two strictly necessary cookies
The site sets two small cookies that exist only to operate the cookie choice itself. One records whether your country requires an opt-in before analytics may run. The other records the choice you made. Neither identifies you, neither is unique to you, and neither can be used to follow you to another website. They are the mechanism by which your preference is respected, so they are set without asking.
Three actions send something to our servers. All three are optional.
Feedback votes
Pressing thumbs up or thumbs down records which calculator it was, which way you voted, and the time. Nothing identifies you.
Error reports
Reporting a problem records which calculator it was, the time, and the message you wrote. That message is a free-text box, so whatever you type into it is stored exactly as written — including a name, an email address or any other personal detail you choose to include. Please do not put anything into that box that you would not want us to hold. We only need enough to reproduce the problem.
Search
Using the search box sends what you typed to our server so that matching calculators can be returned. It is used to answer that request; we do not build a search history against you, and there is no account for one to attach to.
Like any website, ours cannot be reached without our infrastructure providers seeing the technical details of the connection. We use Vercel for hosting and Neon for the database. In the ordinary course of delivering pages, their systems process information such as your IP address, browser and device type, the page requested, the referring page and the time of the request.
This is standard server logging, used to deliver the site, keep it secure and diagnose faults. We do not use it to build profiles of individual visitors. These providers act as processors on our behalf and operate infrastructure outside India, including in the United States and Europe; their own privacy policies govern their handling of that data.
As of July 26, 2026 no advertising is served on this site and no advertising scripts are loaded. This section describes what will apply if and when advertising is introduced.
We intend to fund the site through advertising, most likely Google AdSense. When that begins, Google and its partners may use cookies or similar technologies to serve advertisements based on your prior visits to this or other websites. Google’s use of advertising cookies enables it and its partners to serve ads based on your visits.
This policy and the date above will be updated before any advertising goes live.
We use Google Analytics 4, a service provided by Google, to understand how the site is used — which calculators are opened, which pages are slow, roughly where visitors come from, and what sort of device they use. Our interest is in improving the site, not in identifying individuals, and we do not attempt to link this data to a named person.
To do this, Google Analytics sets cookies on your device and processes information including a randomly generated identifier, your approximate location derived from your IP address, your browser and device type, and the pages you view. Google processes this data on our behalf and as described in its own privacy policy at policies.google.com/privacy. IP addresses are truncated by Google Analytics 4 before being stored.
You can prevent this in several ways:
If you are in the European Economic Area or the United Kingdom, none of this happens until you agree. Analytics cookies are withheld until you press Accept on the banner shown on your first visit, and pressing Decline keeps them off. Elsewhere, analytics runs by default and the opt-outs above remain available to you at any time.
Refusing analytics does not restrict any part of the site. Every calculator works exactly the same either way.
Our calculators can be embedded on other websites. When you use one inside a third-party page, the calculator itself is loaded from our servers, so section 6 applies to that request. Your inputs still stay in your browser and are still never sent to us.
The website hosting the embed is not operated by us, and its own privacy practices, cookies and analytics apply to your visit there. We have no control over, and take no responsibility for, how a third-party site handles your data.
Depending on where you live, you may have rights to access, correct, delete or restrict the use of your personal data, including under India’s Digital Personal Data Protection Act, 2023, the EU and UK GDPR, and California law. We honour these requests regardless of where you are.
There is a practical limit worth being honest about. Because we operate no accounts and collect no identifiers, we usually have no way to connect stored data to a particular person. A feedback vote cannot be traced back to you, so it cannot be found and deleted on request. The exception is an error report in which you included your own details — if you tell us roughly when you sent it and what it concerned, we can locate and delete it.
Write to eaglecalculator@gmail.com and we will respond within 30 days. If you believe we have handled your data improperly, you may complain to your local data protection authority; in India this is the Data Protection Board.
The site is a general-audience reference tool and is not directed at children. We do not knowingly collect personal data from anyone under 18. Since there are no accounts and no profiling, there is very little for a child to disclose — but if you believe a child has sent us personal information through an error report, contact us and we will delete it.
The site is served entirely over HTTPS. Our database is hosted by Neon and is not exposed publicly. Administrative areas are password protected. The most meaningful protection, though, is structural: we hold almost nothing worth stealing, because your calculations never reach us in the first place. No system can be guaranteed perfectly secure, and we make no such guarantee.
This policy will change as the site does — in particular when advertising or analytics are introduced. The date at the top shows when it was last revised. For anything that materially affects your privacy, we will make the change before the practice begins, not after.
