Privacy Policy

Last updated: 2026-05-08

Short version

Kdp.Cool and the kdp.cool family of tools (including calc.kdp.cool) run entirely in your browser. We do not ask for accounts, do not collect personal information, and do not sell data. Anything you enter into a tool stays on your device.

What we collect

• Anonymous traffic analytics via Cloudflare's built-in Web Analytics (no cookies, no fingerprinting).
• Tool state in URL parameters when you change inputs on a tool page — this is so you can share scenarios. Nothing is sent to a server beyond the static page request.
• Advertising via Google AdSense. AdSense may use cookies and third-party identifiers to serve personalized ads, subject to Google's privacy policy. You can opt out of personalized ads at Google Ads Settings.

What we don't collect

• Email addresses
• Names
• The values you enter into our tools (these never leave your browser)
• Account credentials (we have no accounts)

Cookies

Kdp.Cool itself does not set cookies. Google AdSense may set cookies to serve and measure ads. If you're in the EU, EEA, or UK, AdSense will show a consent prompt before personalized ads are served.

Children

Kdp.Cool is not directed at children under 13. We do not knowingly collect any information from children.

Your rights (GDPR / CCPA)

Because we don't store personal information, there's typically nothing to access, delete, or export. If you have questions, see Contact below.

Changes

If we change this policy, we'll update the "Last updated" date above. Material changes will be highlighted on the homepage.
