The calculators work without an account. Project values and preferences are designed to remain in your browser unless you deliberately create a shared link.
Calculator values and local storage
The site uses browser local storage to remember the selected unit system, currency, and recent values for each calculator. This data is stored on your device, not submitted to a project database. If storage is blocked, the calculator continues for the current page session. Reset and clear controls remove saved calculator data from the browser.
Shared links
A shared link places an approved subset of calculator inputs in the URL query. Product prices and personal identity data are excluded by default. Anyone who receives the URL can read the encoded project values, so inspect the address before sharing it. Project labels and notes remain local and are not included in shared links.
Advertising and consent
The site is designed to use Google AdSense after a real publisher identifier and consent system are configured. Advertising technologies may use cookies, device information, or similar identifiers where permitted. In regions that require consent, non-essential advertising storage must not load before the visitor makes a choice. Consent can be changed through the privacy controls when advertising is active.
Optional analytics
Privacy-conscious aggregate analytics may be enabled after a real measurement identifier is configured. Analytics are intended to measure page use and calculator interactions, not capture field values, prices, shared-link queries, project dimensions, or personal identity. Where consent is required, analytics remain disabled until consent is granted.
Server and delivery logs
The hosting and security providers may process network information such as IP address, request path, user agent, timing, and security signals to deliver the site, prevent abuse, and diagnose failures. Their retention and processing practices depend on the production providers and configuration.
Retention
Browser local storage remains until you clear it, reset saved values, or browser policies remove it. Shared links remain wherever recipients or services retain them. Aggregate analytics and advertising retention will follow the configured providers, consent settings, applicable law, and documented account controls.
Your choices
You can use private browsing, block or clear local storage, avoid shared links, decline non-essential consent, and clear site data through browser controls. Blocking storage may remove convenience features but does not disable the core formulas.
