Your privacy is important to us. This Privacy Policy explains how we handle your information when you use our website and calculators.
1. No Registration Required
Our website does not require users to create an account or provide any personal information to use the calculators.
2. Cookies and Local Storage
We do not use cookies to track users across sessions for our own purposes. However, we may use Google Analytics or similar tools to understand how visitors interact with our site. These third-party services may set cookies or use similar technologies in your browser. You can manage or disable cookies through your browser settings.
3. Data Collection
We do not collect, transmit, or store any input values entered into our calculators. All computations are performed locally in your browser using JavaScript.
However, anonymized usage data such as page views, traffic sources, and general interaction patterns may be collected by third-party analytics providers (e.g., Google Analytics) to help us improve our services. This data does not include calculator inputs or personally identifiable information.
4. Advertising and Third-Party Services
5. External Links
Our site may contain links to external websites. We are not responsible for the privacy practices of those sites and encourage you to review their privacy policies separately.
6. Contact
If you have any questions about this Privacy Policy, feel free to contact us at team@calculatorsconverter.com.
Introduction
This Privacy Policy explains, in plain language, what information the Calculators Converter+ website handles and how we treat it. The short version is this: our calculators run entirely in your browser, we do not require accounts, and we do not collect or sell personal data.
This policy applies to the website calculatorsconverter.com and all pages within it. By using the site you agree to the practices described here. If anything is unclear, you are welcome to contact us through the About Us page.
What We Do Not Collect
The most important thing to know is what we deliberately do not collect:
- No calculation data. The numbers you enter into any calculator never leave your device. They are processed in your browser and discarded when you leave the page.
- No accounts. We do not ask for names, emails, or passwords. There is nothing to sign up for.
- No tracking for advertising. We do not sell personal data, because we have no personal data to sell.
If we ever add features that collect information, this policy will be updated first — never silently.
What Little Data May Be Handled Automatically
Like most websites, our hosting infrastructure may automatically keep basic technical logs — for example, the date and time of a request, the page requested, and general connection information — to keep the site secure, diagnose problems, and measure rough traffic levels. These logs do not identify you personally, are kept only as long as needed, and are not sold or shared with third parties for advertising.
We do not use cookies to track you across the internet. Small local storage entries may be used for conveniences such as remembering your chosen theme on your own device. You can clear these at any time through your browser settings.
How Your Device Is Used
All calculator logic runs as code in your browser. That means when you press Calculate, the work happens on your own device — your values are not transmitted to our servers. This is the core of our privacy promise: your numbers are your business, and they stay yours.
Because the calculation is local, results appear instantly, and there is no database of calculations anywhere for anyone to access.
External Links
Some pages include one external link to an official reference — for example a standards body or a health organisation. Once you click an external link, you leave our site, and the privacy practices of that third-party website apply. We recommend checking the policy of any site you visit.
We choose external references carefully and only link to sources we consider reputable and relevant.
Children's Privacy
Our calculators are general-purpose tools used by people of all ages, including students. We do not knowingly collect personal information from children, and because the calculators do not collect any data at all, there is no personal information to gather. If you have concerns about how a child uses the site, the same privacy protections apply to them automatically.
Changes to This Policy
We may update this Privacy Policy from time to time to reflect changes in the site or the law. When we do, the 'last updated' date at the top of the page will change. We encourage you to review this page occasionally, but you can rest assured that our principles will not change: no selling data, no hidden tracking, and calculators that work on your device.
Your Choices and Rights
Because we collect no personal data and hold no calculation history, there is very little to manage — but your choices still matter:
- Clear local data. You can clear site data or storage for calculatorsconverter.com through your browser settings at any time. This removes small conveniences like your saved theme.
- Disable JavaScript. The calculators need JavaScript to run, but if you disable it, the pages themselves will still load and read normally.
- Contact us. If you have any question about how your information is handled, ask us directly — we respond in plain language.
You are never locked in and never required to share anything to use the site. If that ever changes, this policy will say so clearly and in advance.
Security
Security is simpler when there is less data to protect. Because calculations never leave your device, there is no central database of user values that could be exposed. The site itself is served over HTTPS, encrypting the connection between your browser and the site.
We follow sensible maintenance practices — keeping software updated and responding quickly to reported issues — so that visiting the site stays safe. If you ever notice something that looks wrong from a security perspective, please tell us.
Contact Us
If you have any questions about this Privacy Policy or about how the site handles information, please contact us through the About Us page. We are happy to explain our practices in more detail — in plain language, as always.
Frequently Asked Questions
Does this site collect my personal information?
No. The site does not collect personal information. You can use every calculator without an account, and the numbers you enter never leave your device.
Are the numbers I enter into a calculator stored anywhere?
No. Calculations run entirely in your browser. Nothing you type is sent to a server, stored in a database, or kept after you leave the page.
Does the site use cookies?
The site does not use cookies to track you across the internet. Small local storage entries may be used for device-level conveniences such as remembering your theme, and you can clear them in your browser settings.
Do you sell my data to advertisers?
No. We do not sell data, because we do not collect personal data. There is nothing to sell.
Do I need to create an account to use the calculators?
No. There is no sign-up, no email, and no login anywhere on the site.
Does the site track my browsing across other websites?
No. We do not use cross-site tracking cookies or advertising trackers.
Can I use the calculators without an internet connection?
Once a calculator page has loaded, most calculations work offline because they run in your browser.
Why do calculators work in my browser instead of on a server?
Processing in the browser is faster, more private, and cheaper to run — and it means your numbers never travel across the internet.
Do you keep server logs?
Our hosting infrastructure may keep basic technical logs for security and troubleshooting, such as request times and pages requested. These do not personally identify you and are not sold or shared for advertising.
How long is log data kept?
Only as long as needed for security and operational purposes, and then it is discarded.
Do you use analytics tools?
If basic, anonymised analytics are used at any point, they measure site-level traffic patterns only — never individual users and never calculation inputs.
What happens when I click an external link?
You leave our site and the third-party website's own privacy policy applies from that point. We link only to references we consider reputable.
Do you collect data from children?
No. The site does not collect personal information from anyone, including children. Students can use the calculators with the same privacy protections as everyone else.
Can I request deletion of my data?
There is nothing to delete: we hold no personal data and no calculation history. If you entered values into a calculator, they were discarded the moment you left the page.
Do you share data with third parties?
We do not share personal data with third parties because we do not collect it.
Is my activity on the site anonymous?
Yes. Your calculations are private and stay on your device, and we do not build profiles of visitors.
Do you use fingerprinting or similar tracking?
No. We do not use browser fingerprinting or other covert tracking techniques.
Can I opt out of anything?
There is nothing to opt out of — no tracking cookies, no data collection, and no accounts. Your privacy is the default, not a setting.
Will this policy change?
If the policy changes, the 'last updated' date at the top of the page will change, and significant changes will be described clearly in the policy itself.
Who can I contact about privacy?
Use the contact details on the About Us page. We are happy to answer privacy questions in plain language.
Do you have a GDPR or CCPA notice?
Because we collect no personal data, GDPR and CCPA obligations around personal data simply do not arise. We comply with applicable laws wherever we operate.
Is the connection to the site secure?
The site is served over HTTPS, which encrypts the connection between your browser and the site.
Do you store calculations in the cloud?
No. Calculations are processed locally in your browser and are never uploaded to the cloud.
Can someone else see my results?
No. Results appear only on your screen and are not stored or transmitted anywhere.
What if I enter sensitive numbers, like health or financial values?
The same rule applies to all values: they are processed on your device and never leave it. Health and financial numbers get exactly the same protection as any other input.
Do you send emails or newsletters?
We do not collect email addresses, so we cannot and do not send newsletters.
Are there ads that track me?
The site currently keeps advertising minimal or absent by design. We do not use ad trackers that follow you around the web.
How can I clear local storage on my device?
Use your browser's settings to clear site data or storage for calculatorsconverter.com. This will remove small conveniences like your theme choice.
Do I have rights over data about me?
To the extent any data about you exists at all, it is limited to basic technical logs. You can contact us with any request, and we will respond promptly.
Why do you explain privacy so simply?
Because privacy policies should be readable. If a policy needs a lawyer to understand it, that is a red flag — ours is written for people.
Where is the site hosted?
The site is hosted on standard, reputable infrastructure in secure data centres. As always, no calculation data is stored there — the numbers you enter never leave your device.
Why is there no advertising on this site?
We choose to keep the site clean and focused. Advertising often comes with trackers, and trackers conflict with the privacy promise we make on every page. A free tool that respects your attention is worth more to us than ad revenue.
What should I know about third-party services?
The only time a third party is involved is when you click an external link on a page — for example, an official reference. From that moment, that site's own privacy practices apply. Our calculators themselves never call third-party services with your values.
