Your email stays yours
Most inbox cleaners run on someone else's server and read your mail to do it. MailClean is different: it runs entirely on your computer and talks directly to your email provider.
- ✓ No MailClean server, account or tracking
- ✓ Reads only sender, date and size — never subjects or content
- ✓ Passwords encrypted on your device (AES-256-GCM)
- ✓ Nothing permanently deleted — Trash keeps mail for ~30 days
- ✓ Open source: anyone can check the code

FAQs
›Is MailClean free?
Yes. It is free and open source under the MIT license. There are no accounts, subscriptions or limits.
›Does MailClean read my emails?
No. It reads only each email's sender, date, size, read status and the sender's unsubscribe link. Subjects, message text and attachments are never downloaded, and nothing is sent to any MailClean server — there isn't one.
›Why an app password instead of “Sign in with Google”?
An app password lets the app on your own computer talk directly to your mail server, with no third-party service in between. You can revoke it any time in your Google, Yahoo or Apple account settings.
›Does this website track me?
Only if you accept cookies: the website then uses Google Analytics to count visits and download clicks. The MailClean app itself has no analytics or tracking of any kind.
›Can I undo a clean-up?
Yes. Trash moves emails to your provider's Trash folder, where they stay for about 30 days. Archive just removes them from the inbox.
›Why do macOS or Windows warn me when I open it?
The current builds are not yet code-signed. On macOS right-click the app and choose Open the first time; on Windows click More info → Run anyway.
›Does it work with Outlook or Hotmail?
Not yet. Microsoft no longer allows app passwords for Outlook.com, so it needs Microsoft sign-in, which is in progress.
