Worksheet data
The engine compression worksheet performs its calculations in the visitor's browser. Form entries are not intentionally transmitted to a site database or account system. Pressing “Save on this device” stores the current worksheet in your browser's local storage. “Restore” reads from that same device and browser. Clearing your browser's website data can erase the saved worksheet.
Hosting and usage information
As with other websites, the hosting provider may process network request information to deliver the site and prevent abuse. If privacy-preserving website analytics is enabled through the hosting provider, aggregated pageview and technical performance measurements may be collected. The diagnostic worksheet itself does not contain a third-party advertising or marketing tracker at initial release.
Future advertising and affiliate links
This site does not currently display paid advertisements or active affiliate tracking links. If advertising or monetized referral links are introduced later, this notice should be updated to describe the applicable partners, cookies, disclosures and any visitor choices required by law.
Your choices
You may use the calculator without saving any worksheet locally. Browser settings let you remove saved website data. Printing or copying results is an action on your own device. The site does not provide an account-management or deletion request feature because no website account is created.
