Your data stays in this browser

Parsing, calculations, plots and exports run locally. Datasets, group labels, filenames and results are not sent to a calculation server, analytics, error collector or AI service. This release uses no remote fonts, advertising, tracking pixels, session replay, accounts or cloud storage.

Memory and local files

Datasets stay in memory by default. There is no dataset persistence in cookies, localStorage or IndexedDB. Download a project to save your work; closing or reloading the page loses unsaved work. Project and results files contain your original input and exclusions, so manage those files appropriately on your own device.

Hosting still involves requests

Your browser requests this app and its bundled JavaScript/assets from the host. Host access logs may contain IP address and request metadata. This is not a claim of total anonymity or legal-compliance certification. No data is put into URLs or application console logs.

An optional support link is shown only after a successful export if the owner configured a genuine HTTPS destination. It includes no data, query parameters or referrer. Visiting an external reference or support site is governed by that site's practices.
