Privacy Policy
Effective Date: September 2026 · Transparent data handling practices
1. Overview & Commitment
MixTally ("we", "our", or "the Platform") respects your privacy. This Privacy Policy discloses what information is processed when you visit our website, utilize our interactive calculators, or communicate with us.
2. Information We Process
Calculator Dimensions & Parameters: Dimensions entered into calculators (such as slab length, wall height, or coat counts) are executed client-side inside your web browser. We do not transmit or store your job site measurements on remote databases.
Local Storage (Essential): We use browser localStorage solely to preserve your interface preferences: selected unit system (Imperial vs. Metric), color theme (Dark vs. Light mode), and cookie consent preferences.
Voluntary Correspondence: If you contact us directly via email, we collect your email address and any text provided to respond to your inquiry.
Technical Server Logs: Standard web hosting infrastructure automatically logs routine technical telemetry: IP address, browser user-agent, operating system, and HTTP request headers for security defense and denial-of-service prevention.
3. Advertising & Google AdSense
MixTally may partner with third-party advertising vendors, including Google AdSense, to display non-intrusive advertisements that support the hosting of free construction engineering tools.
Google and third-party vendors use cookies to serve ads based on prior visits to this website or other sites on the Internet. Google's use of advertising cookies enables it and its partners to serve ads to users based on their visits to websites.
Users may opt out of personalized advertising by visiting Google's Ads Settings or by utilizing our on-site Consent Preferences banner.
4. International Data Rights (GDPR & CCPA/CPRA)
Depending on your geographic jurisdiction (such as the European Economic Area, UK, or California), you may have statutory rights regarding your personal information, including the right to request access, rectification, erasure, or restriction of processing. Because MixTally does not maintain user accounts or persistent identifiable profiles, we do not sell or share personal data.
5. Children's Privacy
Our services are directed to adults, contractors, builders, and engineering students. We do not knowingly collect personal identifiable information from children under the age of 13 (or under 16 where applicable by law).
