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
- ✓ Saves only sender, date, size and flags — never subjects or content
- ✓ Starred and important emails are kept when you clean up
- ✓ Optional 6-digit PIN locks the app on shared computers
- ✓ Passwords encrypted on your device (AES-256-GCM)
- ✓ Nothing permanently deleted — Trash keeps mail for ~30 days
- ✓ Open source: anyone can check the code
How MailClean compares
Most inbox cleaners scan your mailbox from their servers — and some free ones pay for it with your data.

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. MailClean asks your provider only for each email's sender, date, size, read/starred status, Gmail tab and unsubscribe link, and saves only those. Subject lines are never saved or shown — Yahoo and AOL send the whole header block, so MailClean picks out the sender and unsubscribe link and discards the rest. Message text is never downloaded, attachments only when you ask to save them, and nothing is sent to any MailClean server — there isn't one.
›Can I clean only my Gmail Promotions tab?
Yes. Pick Promotions (or Updates, Social, Forums, Purchases) in the category filter and everything — totals, senders and clean-ups — covers only that tab. Other providers have no tabs, so the filter applies to Gmail mail.
›Will it delete my starred or important emails?
No. “Keep starred & important” is on by default: when you trash or archive a sender, emails you starred or Gmail marked important stay where they are. You can turn it off on the Senders page.
›Can MailClean clean up automatically?
Yes. Add a rule — for example “always trash emails from this sender” or “archive Gmail Promotions older than 30 days” — and MailClean applies it after every sync, and every 6 hours while the app is open. Starred and important emails are always kept.
›Can MailClean show which apps have access to my account?
MailClean links straight to Google's, Yahoo's, Apple's and Microsoft's own pages that list the apps with access to your account, so you can review and remove them there. It also lists every company that has emailed you, flags security alerts and accounts you haven't heard from in a year — built from sender addresses it already has.
›Can I lock MailClean with a PIN?
Yes. In Security → App lock, set a 6-digit PIN and MailClean asks for it every time it opens; after 5 wrong tries you have to wait before trying again. If you forget it, you can reset MailClean from the lock screen — that removes your connected accounts and scanned data from the app (your mailboxes aren't changed) so you can start fresh.
›How does bulk unsubscribe work?
Select the senders and click Unsubscribe. MailClean first shows which ones it can unsubscribe automatically (one-click, RFC 8058) and which need you to confirm on the sender's page, then does the automatic ones and gives you a button for each of the rest.
›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?
MailClean is free, and code-signing certificates cost a yearly fee, so the downloads aren't signed yet. On Windows, the easiest way is to install MailClean from the Microsoft Store — it's signed by Microsoft, shows no warnings and updates itself. If you use the downloaded file, click More info → Run anyway. On macOS, open the app once, then go to System Settings → Privacy & Security and click Open 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.
