Local means local.

Sheet Zipper is designed to process workbooks on your device.

Workbook data

• Workbook and XLZ contents are read only from paths you select.
• Analyze, Optimize, Archive, and Restore run on the local device.
• Evernivo does not intentionally receive workbook contents, filenames, analysis results, job history, or diagnostics.
• Original source files are never overwritten.

Local application data

Preferences, activity history, trial state, and the random installation identity remain in local application storage. Sensitive licensing state is stored using operating-system credential protection.

Store licensing

When distributed through Microsoft Store, purchase and durable license ownership are handled by Microsoft. Workbook contents and local file paths are not part of license checks.
