This release stores a small preference on your device so VentTools can remember your cookie choice. The website may also use browser storage needed for normal app behaviour and service-worker caching so pages and assets load reliably.
Essential storage supports security, network delivery, saved consent choices and core site operation. It cannot be switched off through the preference panel because the website may not function correctly without it.
Analytics is optional. Google Analytics is connected to the consent control and only loads after you choose Accept analytics. Microsoft Clarity is not included in this release.
No advertising cookies or AdSense ad-serving script are included in this release. The publisher-verification meta tag and ads.txt record do not serve adverts or set advertising cookies. Before AdSense is enabled, VentTools will add the relevant disclosures and, where required, a Google-certified consent-management platform.
You can change the optional analytics preference at any time. The updated choice applies when you next open a calculator page.
