NOXR is a digital tools company focused on building free, fast, and reliable web utilities for everyday people. We believe useful tools shouldn't be locked behind paywalls or require you to create an account. To support our mission and keep these tools 100% free for everyone, we display light, non-intrusive advertisements on our website.
Every tool we build follows three principles: it loads fast, works on any device, and gives you accurate results instantly. No bloat, no friction.
Our growing suite of free tools includes calculators and utilities covering everyday needs. All tools are built as lightweight static web pages that run entirely in your browser.
We are on a mission to make practical digital tools accessible to everyone, regardless of location, device, or internet speed. NOXR tools are designed to work on low-end devices and slow connections — because good software should be for everyone.
Have a suggestion for a new tool, found a bug, or just want to say hello? We'd love to hear from you. Reach us at help@noxr.online and we'll get back to you within 48 hours.

NOXR ("we", "our", or "us") operates the NOXR Tools website and all tools hosted under it. This Privacy Policy explains how we handle information when you use our services. We are committed to protecting your privacy and being transparent about our practices.
NOXR tools are designed to run entirely in your browser. We do not collect, store, or transmit any personal data you enter into our calculators. Specifically:
We may collect anonymous, aggregated usage data (such as page views and general geographic region) through privacy-respecting analytics tools to improve our website. Third-party advertising partners also collect technical information (see Section 3 below).
We work with third-party advertising partners (such as Google AdSense) to serve advertisements when you visit our website. These companies may use cookies, web beacons, and other tracking technologies to collect information about your visits to this and other websites in order to serve ads tailored to your interests. See our Cookie Policy for full details.
Key points regarding our advertising partners:
Additionally, our website loads fonts from Google Fonts. Google may collect limited technical information (such as your IP address and browser type) to serve these resources. Please refer to Google's Privacy Policy for more details.
Since we do not collect or store personal data, there is minimal risk associated with using our tools. All tool computations happen locally in your browser. No data is transmitted to our servers during tool use.
Our tools are suitable for all ages. We do not knowingly collect any personal data from children under the age of 13. If you believe a child has provided us with personal information, please contact us and we will take appropriate action.
We may update this Privacy Policy from time to time. We will post the updated policy on this page with a revised effective date. Your continued use of our tools after any changes indicates your acceptance of the updated policy.

By accessing or using any tool on the NOXR website, you agree to be bound by these Terms of Use. If you do not agree to these terms, please discontinue use of our services immediately.
NOXR provides free online tools for informational and personal use. You may use our tools subject to the following conditions:
Our tools are provided for general informational purposes only. While we strive to ensure accuracy, NOXR does not warrant that the results produced by our calculators are error-free, complete, or suitable for any specific purpose. Results should not be used as a substitute for professional advice — including but not limited to medical, financial, or legal advice.
Our website displays advertisements and may contain links to third-party websites, services, or offers that are not owned or controlled by NOXR. We do not endorse or assume any responsibility for any such third-party sites, information, materials, products, or services. If you access a third-party website or service from NOXR, you do so at your own risk, and you understand that these Terms of Use and our Privacy Policy do not apply to your use of such sites. Your dealings with advertisers found on the website are solely between you and the advertisers.
All content on the NOXR website, including but not limited to the tool designs, code, text, and graphics, is the intellectual property of NOXR and is protected by applicable copyright laws. You may not copy, distribute, or create derivative works from our content without our prior written consent.
Our tools are provided "as is" and "as available" without any warranties, express or implied. NOXR makes no representations or warranties of any kind regarding the accuracy, reliability, completeness, or availability of any tool on this site.
To the fullest extent permitted by law, NOXR shall not be liable for any direct, indirect, incidental, special, or consequential damages arising from your use of, or inability to use, our tools — even if we have been advised of the possibility of such damages.
NOXR reserves the right to modify these Terms of Use at any time. Changes will be effective immediately upon posting. Your continued use of our tools after changes are posted constitutes your acceptance of the revised terms.
These Terms of Use shall be governed by and construed in accordance with applicable law. Any disputes arising under these terms shall be subject to the exclusive jurisdiction of the courts in the applicable jurisdiction.

Cookies are small text files placed on your device when you visit a website. They help websites remember information about your visit, such as preferences and how you interact with the site, and are widely used to make websites work more efficiently and to support advertising.
NOXR keeps cookie use to a minimum since our tools run entirely in your browser and don't require accounts. The cookies on our site generally fall into these categories:
We work with Google AdSense to display advertisements that keep NOXR free for everyone. Google and its advertising partners may set cookies (including DoubleClick cookies) to serve ads based on your visits to this and other websites, and to measure ad performance.
Our site also loads fonts from Google Fonts, a third-party service that may process limited technical information such as your IP address and browser type to deliver these resources.
You can control or delete cookies through your browser settings at any time — most browsers let you block all cookies, block third-party cookies only, or clear cookies that have already been set. Note that blocking all cookies may affect how some parts of the site behave.
To opt out of personalized advertising specifically, visit Google Ads Settings or www.aboutads.info, where several ad networks let you manage your preferences in one place.
We may update this Cookie Policy from time to time to reflect changes in the cookies we use or for legal reasons. We will post the updated policy on this page with a revised effective date.
If you have any questions about this Cookie Policy, please contact us at help@noxr.online.
