List comparison data
Text entered into the DiffLists comparison workspace is processed locally by JavaScript running in your browser. The comparison feature does not transmit, store, or log that text on our servers.
Technical data
Our hosting provider may process ordinary request information needed to deliver the website, such as IP address, browser type, requested URL, timestamps, and security logs. This preview does not include advertising or behavioral analytics.
Downloads and clipboard access
Clipboard and download actions happen only when you select them. Your browser may ask for permission before allowing clipboard access. Export files are created on your device.
Policy changes
This policy will be updated before a final public launch if analytics, contact forms, accounts, or other data-processing features are introduced.
