Privacy

No account, no server-side calculation

There is nothing to sign up for and no account to create. Every project tool on this site calculates its result using code that runs in your own browser. A measurement, a product price, or any other value you type is used to compute that page's result on your device and is never transmitted to a server, because this site has no server that performs calculations to send it to.

Prefilled values and local storage

When a value you enter on one tool, such as a room's dimensions, is also used by another tool, this site can prefill that later field for you so you do not have to retype it. That prefill value is written to your browser's local storage on the device you are using, not to any account or remote database, and it is never transmitted anywhere. Clearing your browser's stored data for this site, or using a private browsing window, clears any prefilled values along with it; nothing is lost beyond that, since every tool still works correctly from a blank field.

What analytics does and does not see

Where analytics is active, it records anonymous, aggregate page-view information, which pages are visited and roughly how, so the site's usefulness can be judged over time. It never receives a measurement, a product choice, a price, a saved plan, or any other value you enter into a tool. There is no mechanism on this site that connects a calculator's inputs or results to an analytics event.

Regional defaults and your choices

Analytics storage defaults to denied for visitors in the European Union, the European Economic Area, the United Kingdom, and Switzerland, without relying on a cookie-consent banner to accomplish that. If your browser sends a Global Privacy Control signal, analytics storage is disabled regardless of region. Everyone, anywhere, can also turn off anonymous analytics for their own visits using the "Privacy choices" control in the site footer. This site never uses advertising cookies, remarketing audiences, or ad-personalization signals.

Hosting

This site is served as static files through a content delivery network, which may keep routine technical logs, such as an IP address and the path requested, for its own security and reliability purposes. Those infrastructure logs are not accessed or repurposed by this site beyond that hosting provider's ordinary operation.
