Calculator inputs
The System Designer runs in the visitor’s browser. ChillSizer does not require an account and the supplied site does not send calculator inputs to a ChillSizer database.
Google Analytics
ChillSizer uses Google Analytics 4 with measurement ID G-R24S8XEL54 to understand aggregate site usage such as page visits and interactions. Google Analytics is loaded with Google Consent Mode v2. Optional analytics storage is denied by default and is updated only after a visitor makes a choice in the site’s analytics-cookie notice.
Google may process information under its own terms and privacy policies. Retention and other Google Analytics property settings are controlled in the site’s Google Analytics account.
Local storage
The site stores the visitor’s analytics choice in first-party browser storage under chillsizerConsent so the same question does not need to be asked on every page. Browser storage may also be used for local interface preferences.
Hosting and security logs
The hosting provider may retain ordinary server logs for operations, security and abuse prevention. Those logs are separate from calculator inputs processed in the browser.
Advertising
Google AdSense is not enabled in this release. If advertising is enabled later, this privacy notice and the consent implementation must be reviewed and updated for the actual advertising services in use.
