Summary
This page describes how the Mac-Cel marketing website at mac-cel.app handles information. We do not collect personal data from visitors to this site.
What this website does not do
We do not ask you to create an account on this site, submit a contact form, or join a mailing list.
We do not run advertising trackers, analytics pixels, or behavioral profiling on this site.
We do not sell, rent, or share visitor information with data brokers or marketers.
What may be processed automatically
Like most websites, this site is hosted on GitHub Pages. GitHub may process standard technical information—such as IP address, browser type, and pages requested—to deliver the site and maintain its infrastructure. That processing is governed by GitHub's privacy policy, not by Mac-Cel collecting data for our own use.
If you follow a link from this site to GitHub, Microsoft, or another third party, their policies apply once you leave mac-cel.app.
The Mac-Cel add-in
Formula and risk analysis in the Mac-Cel add-in runs in Excel on your machine. Mac-Cel does not upload your workbook to our servers for that analysis.
Download and install instructions are provided through GitHub. If you download software or open an issue there, GitHub's terms and privacy policy apply.
For a factual map of what stays on your machine versus what may use Mac-Cel Cloud when you use the add-in, see the Security page.
Children
This site is intended for professional users. We do not knowingly collect personal information from children.
Changes
We may update this page when the site or our practices change. The date at the top of this page shows when it was last revised.
