Data processed by the browser
When you create a ZIP, extract an archive, or compress a file, the browser gets access only to files you selected through the system picker or dropped into the workspace. Their contents, names, relative paths, and processing results are used inside the current Packlet browser session.
The application server is not intended to receive, store, analyze, or log file contents, file names, folder structure, archive contents, or generated results.
Local processing
- Files are not uploaded to Packlet servers for archiving, extraction, or compression.
- ZIP creation and supported compression tasks run in the browser.
- Supported archive extraction can run locally, including through a WebAssembly engine.
- Results are downloaded from locally created browser objects.
Saved sessions
If you save a workspace session, Packlet may store operation state in this browser's IndexedDB. Small sessions may include selected files or results; large sessions may keep metadata only. These data remain on the user's device.
You can clear the session inside the workspace or remove site data through browser settings.
Analytics and advertising
If analytics or advertising is enabled, connected services may collect technical interaction events such as page views or operation starts. These integrations should not receive file names, relative paths, file contents, archive contents, or processing results.
Analytics and advertising systems may use cookies or similar browser identifiers. See the Cookie Policy for details.
Security
Local processing reduces unnecessary network transfer, but it does not replace user caution. Do not open archives from untrusted sources unless you are prepared to process them on your device. Processing capabilities depend on the browser, available memory, and supported Web APIs.
