Your files stay local.

What this application does

Selected CSV and image files are read into browser memory and processed on your device. This build has no file-upload endpoint, account system, email form, analytics tag, ad script, or external JavaScript dependency. Generated exports are saved only when you choose to download them. Closing or reloading the page clears the loaded data.

Language preference

Only your interface language is kept in localStorage on this device. No uploaded file content is saved there. You can remove the preference through your browser’s site-data settings. No cookies are created by this application.

Hosting and external checkout

When opened online, your browser requests the website files from its hosting provider. The provider may process connection metadata such as IP addresses under its own policy; local file processing does not eliminate ordinary web-server logs. An external checkout or support link, if later enabled, opens a separate provider with its own terms and privacy policy. This build does not send your input files to those providers.

Product status and contact

This is a pre-launch build. A seller contact and checkout must be configured before enabling sales. There is no active payment collection in the default package.

Do not submit restricted data unless your own institutional policies allow local browser processing. Verify results before use.
