Privacy Policy
This site is a static calculator experience. If you have questions about privacy, data requests, or deletion inquiries, please use the Email Us button in the footer to contact support directly.
Local-first data handling
MatrixLab Exact uses a local-first architecture. Matrix entries, calculator operations, and transformations run inside your browser memory during normal use. The site does not use a dedicated application backend to receive matrix input values for processing.
You remain responsible for the browser, extensions, plugins, local device settings, and surrounding operating environment used to access the utility. Avoid placing sensitive or regulated personal data in the calculator unless your own device context is appropriate for that use.
Analytics and metadata
If you opt in, this site uses Google Analytics 4 to measure usage and improve the utility. That service may process technical metadata such as page views, browser characteristics, device class, approximate geography, and interaction events according to your browser settings, consent choices, and Google’s systems.
You can reject analytics tracking from the privacy choices banner and reopen that choice later through the footer link labeled Privacy Choices.
Contact for privacy requests
California residents and all users can contact support for privacy-related requests, including questions about data handling, opt-out concerns, or deletion inquiries, by using the Email Us button in the footer.
