Cookies and local storage
The website sets no tracking cookies. What the checker stores in your browser (session storage and an offline cache), and why no consent banner is needed.
Cookies
The public pages and the free checker set no cookies. When you sign in, we set one cookie that keeps you signed in; it is removed when you sign out or when the session expires. We use no analytics, advertising or tracking tools.
Other storage in your browser
| What | Why | How long |
|---|---|---|
| Session storage, one entry | Passing a file from a free tool to the checker, when you ask to open it there | Deleted when the checker reads it, or when the tab closes |
| Offline cache (service worker) | So the checker keeps working without a connection, at your request | Until the next version of the site replaces it, or you clear site data |
None of these contain your files, apart from the one-off hand-off from a tool to the checker, which never leaves your browser. Each is strictly necessary for a service you asked for, so no consent is required.
