Privacy
Short version: what you type into the calculators never leaves your device.
What you type
Every calculation runs in your browser. Recipe names, materials, amounts and pyramids are not sent to any server, and the tools make no network requests of their own.
What is stored on your device
The site uses your browser's local storage, not cookies, to remember your colour theme, your current blend and pyramid, the tab you last used, and any recipes or pyramids you save. This data stays on your device. You can delete it with the Delete buttons on each tool or by clearing this site's data in your browser. Exported recipe files are saved only where you choose.
Analytics
The site uses Cloudflare Web Analytics, which counts page views without cookies or cross-site tracking. It never receives what you type into the tools. Cloudflare, which hosts the site, also processes standard connection data such as IP addresses to deliver pages and protect against abuse.
Links to other sites
Links to sources, sister sites, CleanTempMail and WebTraceCheck open other websites with their own privacy policies. Nothing is passed to them except the click itself.
