What it does

Some of the cool stuff

🧹 Real inbox cleanupWorks on your actual Gmail, Yahoo or Outlook inbox (over IMAP, with an app password). Not a demo.
⏱️ Sweeps when you open itOpening the app checks your mail, at most every 3 hours. Swipe down on Home or tap Run now any time.
🗑️ Junk to Trash, unsubscribedMail that matches your Clear rules, bulk or sales mail with an unsubscribe link, and scam pitches go to Trash, and it unsubscribes you when it can.
🛡️ Never touches the real stuffYour Keep senders, receipts, bank mail, sign-in codes, shipping updates and personal-looking mail are never auto-removed.
🤔 You decide the unsure onesAnything it isn't sure about waits in Review: Keep, Remove, or Remove & unsubscribe, with "Always for this sender".
↩️ Restore anythingThe Auto-removed list has Restore: the message goes back to your inbox and the sender is added to Keep.
📋 Keep and Clear rulesAdd a sender or a domain to always keep it, or to always sweep it.
📊 Removed vs real mailA daily or weekly chart of what got swept and what was real, from your own sweeps on that phone.
🔎 Breach heads-upA free XposedOrNot lookup of your email address in known public breaches. It never sees your password. Old breaches stay on the list even after you change your password: it's a heads-up, not a fix.

What's in the works

What's next

Connect your mail with an app password

This is the only tricky part, and it takes about 5 minutes. Pick your email below and follow the numbered steps. You can do it right on your phone.

Why won't my normal password work?

Gmail, Yahoo and Outlook block your regular password in outside apps, to protect you. Instead, they let you make an app password: a separate 16-letter code that only works for mail apps. It doesn't change your normal password, you don't have to remember it, and you can delete it any time to cut Fatal Sweep off.

It looks like this: abcd efgh ijkl mnop (Gmail shows it in four groups; spaces are fine).

🔒 It stays on your phoneFatal Sweep saves the app password in its storage on your phone, nowhere else.

📨 Only sent for the checkWhen a sweep runs, the app password goes to the mail checker just for that check, then it's dropped. It's never stored on the server.

✂️ You can cut it offDelete the app password at Google, Yahoo or Microsoft and Fatal Sweep can't get in any more. How to revoke it.

Before you start

Fatal Sweep is installed and you've made your account (install steps).
You know your email password, because Google, Yahoo or Microsoft will ask you to sign in again.
Your phone is nearby for a sign-in code.
Use the web browser (Safari or Chrome) for the provider steps, not the Gmail, Yahoo Mail or Outlook app.

Gmail Yahoo Outlook / Hotmail Troubleshooting

Gmail @gmail.com · about 5 minutes

You'll need

2-Step Verification turned on. Google hides App passwords until it's on (step 1).
A personal Google account. Work or school accounts may have it turned off by the admin (see Troubleshooting).

Make the app password

Open myaccount.google.com/signinoptions/two-step-verification and sign in. If it says 2-Step Verification is on, skip to step 3.
Tap Turn on 2-Step Verification and follow Google's prompts (a text code to your phone is fine).
Open myaccount.google.com/apppasswords (Google Account → Security → App passwords). Sign in again if asked.
In App name, type Fatal Sweep and tap Create. (On older screens, choose Other (custom name) first, then type the name and tap Generate.)
Google shows Generated app password: a 16-letter code in four groups. Copy it: on a phone, press and hold the code → Copy. Then tap Done. Google only shows it once; if you lose it, just make a new one.
IMAP: nothing to do on personal Gmail. Google keeps IMAP always on (since January 2025). Only if your Gmail settings still show an IMAP option: on a computer, Gmail → Settings ⚙ → See all settings → Forwarding and POP/IMAP → Enable IMAP → Save Changes.
Now paste it into Fatal Sweep: tap Gmail and paste the code in the field labeled App password.

On a computer instead? Same steps and links. Then send the code to yourself or type it into your phone; spaces don't matter.

Yahoo Mail @yahoo.com · about 3 minutes

You'll need

Your Yahoo sign-in. Yahoo may ask you to confirm with a code to your phone or recovery email.
No IMAP setting to change: Yahoo allows it already.

Make the app password

Open login.yahoo.com/account/security (Yahoo Account security) and sign in.
Scroll to External connections and open the App passwords tab. Not Sign in with Yahoo, that's something else.
Tap Create app password, the purple link next to "What are app passwords?". (Older screens call it Generate app password or Manage app passwords.)
Type Fatal Sweep as the app name and tap Generate password.
Yahoo shows a 16-letter code. Tap Copy (or press and hold → Copy), then Done. It's shown once; you can always make a new one.
Now paste it into Fatal Sweep: tap Yahoo and paste the code in App password, not your Yahoo password.

Heads-up: Microsoft may block this. Microsoft has moved Outlook.com, Hotmail and Live mailboxes to its newer sign-in (OAuth) for mail apps, and many of these accounts now reject app passwords. This version of Fatal Sweep connects with an app password only; it doesn't do Microsoft's newer sign-in. It's worth a try: if your account blocks it, Fatal Sweep tells you right away, and it's Microsoft's setting, not something you did wrong.

You'll need

Two-step verification turned on. Microsoft only shows App passwords when it's on (step 1).
A personal Microsoft account. Work or school (Microsoft 365) mail is controlled by your admin.

Make the app password

Open account.live.com/proofs/manage/additional (Advanced security options) and sign in. If Two-step verification is off, turn it on and follow the prompts.
On the same page, under App passwords, tap Create a new app password.
Microsoft shows the code on the next screen. Copy it (press and hold → Copy), then tap Done.
Allow IMAP, if your account has the switch: open outlook.live.com → Settings ⚙ → Mail → Forwarding and IMAP → turn on Let devices and apps use IMAP → Save.
Now paste it into Fatal Sweep: tap Outlook and paste the code in App password. Never use your Outlook or Hotmail sign-in password.

Got "IMAP is blocked for this account"? Microsoft turned off app-password sign-in for your mailbox. Fatal Sweep can't switch that back on. Gmail or Yahoo will work instead.

Paste it into Fatal Sweep

Open Fatal Sweep from your home screen and unlock it (Face ID or PIN).
On Home, tap Connect mail. (Or tap the Settings gear → Mailboxes.)
Tap Gmail, Yahoo or Outlook. The same steps are on screen there too.
Type your full email address in Email.
Press and hold the field labeled App password → Paste. Spaces are fine. Tap Show to double-check it.
Tap Save in this browser. Fatal Sweep tests the login before it saves. When it works you'll see Connected. Saved in localStorage on this device. and your mailbox under Mailboxes.
Go back to Home and swipe down (or tap Run now) for your first sweep. Check Review for anything it wasn't sure about.

More than one account? Go to Settings → Mailboxes and tap the provider again (for example Add Gmail). Each account needs its own app password.

Troubleshooting

When it fights back

I can't find "App passwords"

2-Step Verification (Google) or two-step verification (Microsoft) is off. Turn it on first; App passwords shows up after.
Use the direct link in your provider's steps above. The menu can be hard to find.
Work or school account (Google Workspace, Microsoft 365): your admin may have turned app passwords off. Only they can change it.
Google Advanced Protection, or 2-Step Verification with security keys only: Google doesn't offer app passwords on those accounts.
Yahoo: make sure you're on the App passwords tab under External connections, not Sign in with Yahoo.

"Wrong app password. The mail server rejected it."

You may have used your normal email password. Use the 16-letter app password.
Check the email address is the same account you made the app password on.
Copy and paste rather than typing; tap Show to check it. Spaces don't matter.
Still stuck? Delete that app password and make a fresh one. It's free and takes a minute.

"IMAP is blocked for this account"

Gmail: IMAP is always on for personal Gmail. If your settings still show an IMAP option, choose Enable IMAP and Save Changes (Gmail step 6).
Outlook / Hotmail: Microsoft blocks app-password sign-in on many accounts. Turn on Let devices and apps use IMAP (Outlook step 4) and try again. If it still fails, Microsoft won't allow it for your account; this version of Fatal Sweep doesn't support Microsoft's newer sign-in (OAuth).

"Network problem. Could not reach the mail checker."

Your phone lost its connection, or the network blocks it. Try again on Wi-Fi or mobile data.

"App password is missing on this device"

App passwords are saved on each phone (and each browser) separately. If you set it up somewhere else, cleared website data, or reinstalled, add the mailbox again: Settings → Mailboxes → tap the provider → paste a new app password. On iPhone, the home-screen app keeps its own storage, separate from Safari, so set it up inside the home-screen app.

Adding more than one account

Settings → Mailboxes → tap the provider again (for example Add Gmail). You can add more than one of each. Make a separate app password for each account.

Changing or removing a mailbox

Settings → Mailboxes → Edit to paste a new app password, or Disconnect to remove it from Fatal Sweep.

Revoking an app password later

Gmail: myaccount.google.com/apppasswords → tap the trash can next to Fatal Sweep. Changing your Google password also cancels your app passwords.
Yahoo: Account security → External connections → App passwords → remove Fatal Sweep.
Outlook: Advanced security options → App passwords → Remove existing app passwords (Microsoft removes all of them at once).
Then Disconnect the mailbox in Fatal Sweep (Settings → Mailboxes), or it will show a wrong-password error.

I lost the code before pasting it

No problem. Providers only show it once, so make a new one with the same steps. You can delete the old one.

FAQ

Questions from the crypt

Is it free?

Yes. No ads, no subscription, and it doesn't sell your data. There's an optional Donate button if you want to support it.

Which email works?

Gmail, Yahoo and Outlook / Hotmail. Some Microsoft accounts block app-password sign-in (see the Outlook steps). Other providers aren't supported yet.

Why do I need an app password?

Gmail, Yahoo and Outlook don't let outside apps use your normal password. An app password is a separate code just for mail apps, and you can delete it any time. Step-by-step guide.

Where is my app password kept?

On your phone only, in Fatal Sweep's storage. It's sent to the mail checker only for a check you start, then dropped. It's never stored on a server.

Does it delete my mail forever?

No. Removed mail goes to your mailbox's Trash, and the Auto-removed list has Restore to put it back in your inbox (and add the sender to Keep).

Does it run when the app is closed?

No. A web app can't run while it's closed. It sweeps when you open it (at most every 3 hours), when you swipe down on Home, or when you tap Run now.

Will it remove me from people-search sites by itself?

No. It walks you through each opt-out step by step (Spokeo, TruePeopleSearch, FastPeopleSearch, Whitepages) and tracks where you are. You send the request. With your mail connected, it spots the site's confirm email and moves you to the next step.

What does the breach check do?

A free XposedOrNot lookup of your email address in known public breaches. It never sees your password. It's a heads-up: old breaches stay listed even after you change your password.

What if I forget my PIN?

Reset it with Face ID. Without Face ID, a forgotten PIN can't be recovered: you'd erase the app's data on that phone and set it up again.

New phone?

Everything lives on the phone you set it up on, so set it up again on the new one and make new app passwords.

Is it made by Google, Yahoo or Microsoft?

No. Fatal Sweep is an independent app by Fatal, not affiliated with Google, Yahoo or Microsoft.

Sweep it clean.

Open it, add it to your home screen, and connect your mail.
