The short version
This site does not collect, store, or transmit any personal information. All calculations happen locally in your browser. Advertising is provided by Google AdSense, which may use cookies in accordance with their own privacy policy.
No personal data is collected or stored by this application. All LED system calculations are performed entirely within your browser. No configuration data, system specifications, or build parameters are transmitted to any server operated by us.
This site displays advertisements served by Google AdSense. Google may use cookies to serve ads based on your prior visits to this and other websites. You can opt out of personalised advertising by visiting Google's Ads Settings or aboutads.info.
This site uses Google AdSense (advertising) and Google Fonts (font delivery). We do not sell, share, or otherwise disclose any user data to third parties beyond these integrations.
Because we do not collect personal data, there is nothing to retain or delete. All calculator state is held in your browser's memory and discarded when you close or refresh the page.
Depending on your location, you may have rights to access, correct, or delete personal data we hold about you, and to object to or restrict certain processing (for example, under GDPR for EU/UK visitors or CCPA for California residents). Since we do not require accounts or store calculation inputs server-side, there is generally little personal data to request — see "Information we collect" above. For any request, use the contact method below.
This site is not directed at children under 13, and we do not knowingly collect personal information from children. If you believe a child has provided personal information to us, please contact us so we can remove it.
We may update this Privacy Policy as the site's features change, for example if we add new analytics or advertising integrations. Material changes will be reflected by updating the "last updated" date on this page.
If you have questions about this privacy policy, please reach out via the contact details provided on the About page.
