Privacy policy

ColsonSuperApps LLC ("Tavenza", "we") built this site to be private by default. You can use every calculator without an account, and we don't ask for your name, email or any personal details.

What we collect

Your calculator inputs stay in your browser. All estimates are computed client-side; we do not send, receive or store the numbers you enter. We keep no user accounts and no database of personal information.

Analytics

We use privacy-friendly analytics (Google Analytics 4 and/or Cloudflare Web Analytics) to understand aggregate, non-identifying traffic — pages viewed, country, device type. Google Analytics may set cookies; Cloudflare Web Analytics is cookieless. We never sell your data.

Advertising

Tavenza is ad-supported. Third-party vendors, including Google (AdSense), may use cookies or device identifiers to serve and measure ads. In the EEA, UK and Switzerland we use Google Consent Mode v2 with a certified consent dialog, and personalized advertising storage defaults to denied until you choose. You can learn more and opt out of personalized Google ads at Google Ads Settings.

Affiliate links

When you choose to get a real quote, we may route you to a partner via an affiliate link; that partner's own privacy policy then applies. We never pass them data you didn't choose to provide. See our affiliate disclosure.

Your choices

You can block cookies in your browser, use the consent controls where shown, and opt out of personalized ads via the link above. Because we hold no personal data about you, there's nothing for us to delete on request — but you can contact ColsonSuperApps LLC with any question.
