Privacy Policy
Last updated: October 2026
1. What we collect
StackMatrix is a static informational website. We do not require accounts, and we do not collect names, email addresses, or payment details. The interactive cost calculator runs entirely in your browser — your inputs never leave your device.
2. Cookies & analytics
We may use privacy-friendly analytics and standard browser cookies or local storage to understand aggregate usage (e.g. which pages are visited). This data is aggregated and never sold to third parties. You can disable cookies in your browser settings at any time.
3. Affiliate link tracking
Some outbound links on this site are affiliate links. When you click one, the destination vendor or affiliate network (such as PartnerStack or Impact) may set cookies or use tracking parameters to attribute any resulting signup to us, which may earn us a referral commission at no extra cost to you. Their own privacy policies govern that tracking.
4. Third-party vendors
Clicking a "Visit" button takes you to a third-party vendor's website, which operates under its own privacy policy. We are not responsible for their data practices.
