Privacy policy

Project Calculators does not require an account. Calculator project information and calculator usage totals are stored on your device through browser storage.

Information stored locally

Saved project sections, display preferences, and usage totals can remain in your browser until you clear site data. Usage totals are limited to pour shape, dimension-unit selection, and mix selection. They do not include project dimensions, prices, names, or notes.

Website analytics

Cloudflare Web Analytics is enabled to help measure site traffic and performance. Cloudflare may process limited request and technical information such as an IP address, browser, device, referring page, and page-load performance. Calculator field values are not intentionally sent through the calculator's local usage-total feature.

Share links

If you create and send a share link, information encoded in that link can be seen by its recipients and may appear in browser history or server logs. Review a link before sharing it and avoid private information.

External services

External websites, including affiliate retailers, apply their own privacy policies after you follow a link. Project Calculators may earn from qualifying purchases through disclosed affiliate links.
