Flux Media Systems ("we," "us," or "our") operates the website fluxmediasystems.com and its subdomains (including calculator subdomains). This Privacy Policy explains how we collect, use, and protect your information when you use our free online tools and guides.
Our tools are designed to work entirely in your browser. We do not collect, store, or transmit any personal data you enter into our calculators or tools. All calculations are performed locally on your device and no input data is sent to our servers.
We may automatically collect non-personal information including: browser type and version; operating system; pages visited and time spent; referring website; and general geographic location (country or region level only, via Google Analytics).
We use Google AdSense to display advertisements on our website. Google AdSense uses cookies to serve ads based on your prior visits to our website and other sites on the internet. Ads help keep our tools free to use.
You may opt out of personalised advertising by visiting Google's Ads Settings. Google's use of advertising cookies enables it and its partners to serve ads based on your visit to our sites. For more information, visit Google's Privacy & Terms.
We use cookies for the following purposes: analytics (to understand how visitors use our site, via Google Analytics); advertising (to serve relevant ads, via Google AdSense); and preferences (to remember settings within our tools, such as tab state). You can control cookies through your browser settings. Disabling cookies may affect the functionality of some features and ad personalisation.
We use Google Analytics to analyse website traffic. Google Analytics collects information such as how often users visit the site, which pages they visit, and how they arrived. We use this information to improve our tools and content. Google Analytics collects the IP address assigned to you on the date you visit, but not your name or other personally identifying information. We do not combine the information collected by Google Analytics with any personally identifiable information.
If you use our contact form, the information you submit (name, email address, and message) is transmitted to us via a third-party form service. We use this information only to respond to your enquiry. We do not add contact form submissions to mailing lists or share them with third parties.
Our website may contain links to third-party websites, including links to official government sources (HMRC, GOV.UK, IRS) and reference materials. We are not responsible for the privacy practices or content of those sites. We encourage you to read the privacy policies of any third-party sites you visit.
Our services are not directed to children under the age of 13. We do not knowingly collect personal information from children under 13. If you believe we have inadvertently collected such information, please contact us immediately via our contact page.
We do not retain personal data entered into our tools. Contact form submissions are retained only as long as necessary to respond to your enquiry. Analytics data is retained in accordance with Google's standard data retention policies.
If you are located in the UK or EU, you have rights under data protection law including the right to access, correct, or delete personal data we hold about you. Since we do not collect personal data through tool use, these rights primarily apply to any contact form submissions. To exercise your rights, please contact us via our contact page.
We may update this Privacy Policy from time to time. We will notify you of significant changes by posting the new policy on this page with an updated date. Your continued use of our services after any changes constitutes your acceptance of the updated policy.
