Your privacy matters to us. Here's how we handle your data.
Last updated: February 2026
OmniCalculator Pro ("we," "our," "us") is committed to protecting your privacy. This Privacy Policy explains how we handle information when you use our website at omnicalculator.pro.
We believe in privacy by design. Our calculators are designed to work without collecting personal information:
All calculations are performed locally in your web browser. Your data never leaves your device.
We may collect limited, anonymous information to improve our service:
This data is aggregated and cannot identify individual users.
Our website may use the following third-party services:
To keep OmniCalculator Pro free, we display advertisements through third-party advertising networks. This involves the following:
For more information on how Google uses data when you use our Site, please see Google's Privacy & Terms.
A cookie is a small text file stored on your device. We and our advertising partners use cookies to serve relevant ads, measure ad performance, and understand anonymous site usage. You can control or delete cookies through your browser settings at any time. Disabling cookies may affect the ads you see but will not prevent you from using our calculators, which run entirely in your browser.
We take security seriously:
Our calculators are safe for users of all ages. We do not knowingly collect any information from children under 13. Our educational tools are designed to be helpful for students and learners.
Since we don't collect personal data, there's nothing to delete or export. You can use our calculators with confidence knowing your information stays private.
We may update this Privacy Policy from time to time. Any changes will be posted on this page with an updated revision date. We encourage you to review this policy periodically.
If you have questions about this Privacy Policy, please contact us.
The most important thing to understand about privacy on this site is structural rather than contractual: our calculators run entirely in your browser. When you enter a salary, a weight, a loan balance or a date of birth, that information is processed by JavaScript on your own device and never transmitted to us. We do not have a copy, we cannot retrieve one, and there is nothing for us to lose in a breach.
This is a design decision rather than a policy promise, and it is the reason we can state it so plainly. There is no account system, no login, and no server-side processing behind any calculator on this site.
Like most websites, our hosting infrastructure and analytics record limited technical information when a page loads. This is aggregate in nature and used to understand how the site is performing.
| Data | Purpose |
|---|---|
| Pages visited and time on page | Understanding which calculators are useful |
| Referring source | Knowing how visitors find the site |
| Browser and device type | Ensuring pages work across devices |
| Approximate location (country or region) | Aggregate audience understanding |
We use Google Analytics for this. It aggregates data across visitors and is not used to build a profile of any individual by us. You can prevent Analytics collection entirely using Google's browser opt-out tools or standard browser privacy settings.
You have meaningful control over what is collected, and none of these choices prevent you from using the calculators.
Depending on where you live, you may have specific rights under laws such as the GDPR in Europe or the CCPA in California, including rights of access, correction and deletion. Because we do not hold personal information tied to individuals, there is generally little for us to retrieve or delete. If you have a question about data associated with your visit, contact us and we will explain what does and does not exist.
This site is intended for general audiences and is not directed at children under 13. We do not knowingly collect personal information from children. Because the calculators collect no personal information from anyone, there is no child-specific data held. If you believe a child has provided personal information through correspondence with us, please contact us and we will delete it.
The strongest security measure available to any website is not holding data in the first place, and that is the approach we have taken with calculator inputs. For the limited technical data described above, we rely on established providers with their own security practices, and the site is served over an encrypted HTTPS connection.
If our practices change, this page will be updated and the revision date amended. Material changes, such as introducing a feature that collects information we do not currently collect, will be described clearly rather than buried in amended wording.
If anything here is unclear, or you want to know precisely what happens to a particular piece of information, please contact us. Questions about privacy are welcome and we will answer them directly.
