Your calculation stays in your browser.

Calculator values are processed on your device and are not sent to SkipperCalc. The hosting provider may process technical access logs such as IP address and user agent to serve and protect the site.

The suggestion form sends the data you enter to SkipperCalc via FormSubmit. Email is optional and only used so we can reply. Do not include sensitive data in the message.

Google Analytics is prepared with denied consent by default. We only activate visit measurement if you accept the privacy notice. If you reject it, analytics permission is not granted. Your preference is stored in your browser so you are not asked on every page.

This version does not use advertising. External links have their own policies. If AdSense or another advertising service is introduced, this information will be updated and consent configured before those services are activated.
