Summary

DengTTSTools does not collect, store, transmit, or sell any data you enter into our calculators. All calculations happen locally in your browser.

What we don't collect

• No financial inputs (sale price, COGS, weights) — calculations are 100% client-side.
• No account, no email, no name.
• No IP-based tracking beyond anonymous aggregate analytics.
• No cookies set by this site.

What we do collect

• Aggregate, anonymized page-view counts via a privacy-respecting tool.
• Standard server logs retained briefly for security. Deleted after 30 days.

Advertising

This site may show ads in the future. If we add Google AdSense or any advertising network, we'll update this policy and serve ads only on tool pages — never on pages that ask you to enter financial data.
