CalcVerdict is a free calculator platform. This policy explains, in plain language, what information reaches us when you use the site, why it reaches us, how long it is kept, and what you can do about it. We have written it to be read rather than skimmed past, and we have kept the site’s data footprint small enough that the honest answer to most questions is “we do not collect that.”
The short version
You do not need an account to use any calculator here, and we do not ask for one. Every calculation runs from values you type into a form; the result is rendered on our server and handed back as a shareable web address. We do not store the numbers you enter in any database tied to you, and we do not sell personal information to anyone.
Information we collect
Information you provide
The only information you actively give us is what you type into a calculator form or into the form on our contact page. Calculator inputs travel in the address bar as query parameters so that a result can be bookmarked or shared. They are processed to produce the answer and are not written to a user profile. If you email us, we hold that message and your reply address for as long as it takes to answer you and to keep a record of the exchange.
Optional calculator follow-up
After a calculator produces a result, you may optionally give us your name and email so we can send relevant follow-up resources. We record the calculator ID and category that brought you to the form so we can understand which tools are useful. Review-invitation consent and marketing consent are separate choices; we do not send either without the corresponding opt-in. These details are delivered to CalcVerdict’s lead inbox and are not stored in the calculator URL or in your browser.
Information collected automatically
Like nearly every website, our servers and our hosting provider record technical details about each request. That typically includes your IP address, the approximate region it resolves to, your browser type and version, your operating system, your device screen size, the page you requested, the page that referred you, and the date and time. We use this to keep the site available, to diagnose errors, to measure page speed, and to detect abuse such as automated scraping. We do not use it to build a marketing profile of you.
Cookies and similar technologies
A cookie is a small text file a site asks your browser to keep. CalcVerdict itself uses cookies sparingly. The one cookie we set by default records your light or dark theme preference so the page does not flash the wrong colours when you return. It contains a single word, holds nothing that identifies you, and can be cleared at any time.
Third parties may set their own cookies through this site, principally for advertising and for aggregate measurement. Those cookies are governed by the policies of the companies that set them, which are linked below.
Advertising, Google AdSense, and the DART cookie
CalcVerdict may display advertising served by Google AdSense. Google is a third-party vendor, and as such it uses cookies to serve advertisements on this site. Google’s use of advertising cookies — historically known as the DART cookie — enables it and its partners to serve advertisements to you based on your visits to this site and other sites on the internet.
Third-party vendors and advertising networks other than Google, which may include ad exchanges, analytics providers, and social platforms such as Facebook, may likewise use cookies, web beacons, or comparable identifiers to measure ad performance and to serve ads they believe are relevant to you. We do not hand these vendors your name or your email address; what they observe is browser-level activity such as which pages loaded and which ads were shown.
You can control this directly:
- Opt out of personalised advertising in Google’s Ads Settings, and read the full terms at policies.google.com/technologies/ads.
- Opt out of many participating networks at once through the Network Advertising Initiative or the Digital Advertising Alliance opt-out pages.
- Disable or delete cookies in your browser settings. Every major browser lets you block third-party cookies, clear existing ones, or reject all of them. Blocking cookies does not break any calculator on this site — the tools are server-rendered and work without JavaScript, let alone without cookies.
Consent
Where the law requires it, including for visitors in the European Economic Area, the United Kingdom, and Switzerland, non-essential cookies are set only after you have given consent through the consent notice presented on your first visit. You can change or withdraw that consent at any time by clearing this site’s cookies and making a new choice when the notice reappears. Essential cookies — the theme preference, and anything strictly required to serve the page securely — do not depend on consent, because the site cannot function correctly without them.
How long data is kept
Retention is deliberately short. Our theme cookie expires one year after it is set. Server request logs are retained for up to ninety days and then deleted or aggregated into counts that identify nobody. Email you send us is kept for up to twenty-four months so that we can follow up on a bug report or a formula correction, then deleted. Cookies set by advertising vendors are retained according to those vendors’ own schedules, which are described in their policies; Google’s advertising cookies generally expire within two years of the last activity.
Your rights
Depending on where you live — under the GDPR in Europe and the UK, and under comparable state laws in the United States including the CCPA and CPRA in California — you may have the right to ask what personal data we hold about you, to have it corrected, to have it erased, to restrict or object to its processing, to receive a copy in a portable format, and to withdraw consent you previously gave. We do not sell personal information and we do not share it for cross-context behavioural advertising in exchange for money.
Because we do not operate accounts, in most cases we simply hold no personal data tied to you, and the honest answer to an access request is that there is nothing to return. Where we do hold something — an email thread, for example — write to us and we will act on the request within thirty days.
Children
This site is intended for a general audience and is not directed at children under thirteen. We do not knowingly collect personal information from children. If you believe a child has sent us personal information, contact us and we will delete it.
Security and international transfers
The site is served over HTTPS everywhere, so traffic between your browser and our servers is encrypted in transit. Our hosting and advertising providers operate globally, which means technical data such as an IP address may be processed on servers outside your country, including in the United States, under the safeguards those providers publish. No method of transmission or storage is perfectly secure, and we do not claim otherwise.
Links to other sites
Our articles cite primary sources — statutes, standards bodies, government agencies, and academic publications — and those links lead away from CalcVerdict. We do not control those sites and this policy does not apply to them. Read their own privacy notices before giving them information.
Changes to this policy
If this policy changes materially, we will update the date at the top of the page and, for significant changes, note them on the site. Continued use of CalcVerdict after a change means you accept the revised policy.
Contact
Questions about privacy, or a request relating to your rights, can be sent through our contact page. Our terms of service govern your use of the calculators themselves, and about CalcVerdict explains who builds them.
