Stealth Mode Pass
Stealth Mode. Delete without them noticing.
Stealth Mode removes your Facebook Messenger messages from the oldest first, with randomized 5 to 7 second delays between each removal. The recent visible part of the chat, the part the other person actually sees when they open the conversation, stays intact until the very end. They notice nothing unless they scroll years back into the history. Works on messenger.com and facebook.com/messages, across encrypted and legacy threads.
Free extension. Stealth Mode unlocks with a Pass.
The problem
The problem with deleting Messenger messages fast.
Messenger's native Remove for everyone is one message at a time, and it always operates on the most recent visible bubble. If you panic-delete your last twenty messages by hand, the other person sees gaps right at the bottom of the chat, exactly where they look when they reopen the conversation. The recent timeline is the visible timeline, and that's where the damage shows.
A bulk deleter that respects this default order has the same problem at scale. Remove 500 recent messages in 50 minutes, and the other person opens the chat to a wall of "You removed a message" markers right where their eyes land. Their own replies sit there orphaned, with nothing left to answer. Speed without order is a confession.
Stealth Mode solves this by flipping the deletion order. It starts from the bottom of the scrollback, the messages from months or years ago, and only reaches the recent visible part if the job runs long enough to get there. By then you can already stop. The cleanup hides in the dead zone that nobody re-reads.
How it works
How does Stealth Mode work, step by step?
Stealth Mode is a deletion order plus a delay policy. Two ingredients, both deliberate. Here is the exact mechanism Unsay uses when you toggle it on.
-
01
Full thread scan, both threads
Unsay walks through your conversation to build a sorted index of your own messages, across the encrypted thread and the migrated legacy thread. Nothing is deleted during the scan. At the end you see a count: "47 messages found, oldest from 2018-08-14, most recent from today".
-
02
Reverse the deletion order
With Stealth Mode ON, the removal loop starts at the oldest message in the index and walks forward in time. With Stealth Mode OFF (free default), the loop starts at the most recent message and walks backward. Same removal, opposite direction.
-
03
Randomized 5 to 7 second delay
Between each removal, Unsay waits a random number of milliseconds between 5,000 and 7,000. The jitter is real randomization, not a fixed pause, so the rhythm doesn't look mechanical to Messenger's detection. This matches roughly the speed of a human deleting by hand.
-
04
Official Remove for everyone
Each deletion uses the same Remove for everyone action you get when you long-press a message in Messenger. The message is removed from both sides of the conversation, permanently, on encrypted and legacy threads alike.
-
05
Pause, resume, stop, at any time
The side panel shows live progress: "28 / 47 removed". Click Pause and the loop stops at the current message. Click Resume and it picks up at the next pending one. Click Stop and the job ends, with everything already removed staying removed (Messenger has no undo).
Definition
Stealth Mode is a deletion mode that processes Facebook Messenger messages from the oldest to the most recent, with randomized 5 to 7 second delays between each removal, so the recipient's currently visible chat view stays intact while old messages are removed for everyone at the far end of the scrollback.
Notifications
Does Messenger notify the other person when you remove a message?
No. Messenger sends no push notification, in-app alert, or email when you use Remove for everyone. The message is quietly replaced by a small "You removed a message" line on both sides. There is no badge, no alert, and nothing that pulls the other person back to the conversation.
That small marker is the one trace Remove for everyone leaves behind. It sits exactly where the deleted bubble used to be. So the question isn't whether a trace exists, it's where that trace lands: in the recent part they're staring at, or buried years deep in a scrollback nobody opens.
The only ways the recipient can notice are: (1) they happen to have the chat open at the exact moment you delete a message still on their screen, (2) they scroll back and stumble on a run of "You removed a message" lines, or (3) they had a push preview of the message before you removed it. Stealth Mode minimizes cases (1) and (2) by removing in the part of the scrollback that's almost never on screen.
Comparison
Stealth Mode vs Standard Mode: what's actually different?
Both modes use the same Messenger Remove for everyone action and the same 5 to 7 second delay. The difference is the order, the visibility, and the tier. Here's the side-by-side.
| Dimension | Standard Mode (free default) | Stealth Mode (Pass) |
|---|---|---|
| Deletion order | Most recent first | Oldest first |
| Visible part of chat | Cleared immediately, markers appear at the top | Stays intact until the very end |
| Per-message delay | 5 to 7 seconds, randomized | 5 to 7 seconds, randomized |
| Underlying action | Remove for everyone | Remove for everyone |
| Encrypted and legacy threads | Both | Both |
| Pause / resume | Yes | Yes |
| Weekly limit | 50 messages | Unlimited |
| Detection risk | Higher (recent gaps obvious) | Lower (old markers unread) |
| Tier | Free | Pass, from $30 |
Use cases
Who is Stealth Mode for?
Stealth Mode exists for situations where the deletion itself would say something. Four archetypes show up again and again in the people who pay for it.
The ex who regrets the long thread
Years of confessions, drunk texts, "I miss you" at 3am, and old replies that don't match who you are now. You want them gone, but you still occasionally cross paths in Messenger. If the recent part of the chat suddenly thins out, they will scroll up to check, and that's the worst possible moment for them to find your latest messages gone. Stealth keeps the recent banter intact while the embarrassing archive quietly disappears.
The privacy-conscious user
You don't have anything dramatic to hide, you just don't like the idea of a decade of your private conversations sitting on Meta's servers. You want to clean up periodically, on principle, without making it look like a sudden purge that triggers questions. Stealth treats your privacy the way it should be treated, quietly and without fanfare.
The public figure pruning old takes
Someone with an audience whose Messenger chats occasionally surface in screenshots. You want to remove old hot takes, half-baked opinions, and statements that don't represent you anymore, without putting up a billboard saying "I'm deleting evidence". Oldest-first deletion lets you clean the archive without disturbing active conversations.
The person leaving a relationship slowly
You're not ready to block, unfriend, or have a final conversation, but you don't want to leave a trail of vulnerable messages either. Stealth lets you walk out of the past quietly, removing your own contributions while everything they sent stays where it was. No drama, no announcement.
Honest limits
What Stealth Mode does NOT do.
Stealth Mode is a real feature with real limits. Here is what it doesn't do, so nobody buys it for the wrong reason.
-
Not invisible during deletion
If the recipient has the chat open at the same moment Stealth is processing a message that's currently on their screen, they will see the "You removed a message" marker appear in real time. Stealth lowers this risk by deleting where they're not looking, but it doesn't cloak the removal itself.
-
Not reversible
Messenger has no undo for Remove for everyone. Once Stealth removes a message, it's gone from both sides, permanently, on encrypted and legacy threads alike. Make sure you actually want a message gone before you start the job, because there is no getting it back.
-
Doesn't delete voice or video calls
Messenger does not expose Remove for everyone for voice or video call entries in the conversation, only for text, photo, video, voice message, and share bubbles. Call rows in your scrollback are counted separately and left alone by Stealth Mode (or any other mode).
-
Not instant on big threads
A 1,000-message conversation takes about 1 hour 40 minutes. A 10,000-message thread takes 16 to 17 hours. Stealth runs at the same speed as Standard Mode, because the bottleneck is the discreet delay between removals, not the order. You can pause and resume, but you can't sprint.

FAQ
Stealth Mode, answered honestly.
Does Messenger notify the other person when you remove a message?
No. Messenger sends no push notification or alert when you use Remove for everyone. The message is replaced by a small "You removed a message" line on both sides, with no badge and no alert. The other person only notices if they happen to be looking at that exact spot in the conversation. Stealth Mode keeps those small markers deep in the old scrollback, away from the visible part of the chat.
Why does Stealth Mode delete from the oldest first?
Because Messenger shows the most recent messages when the other person opens the chat. If you remove those first, your latest replies vanish from their view, like you ghosted them mid-conversation. Deleting from the oldest first keeps the recent visible part intact and hides the cleanup far back in the scrollback, where nobody scrolls.
Does Stealth Mode work on encrypted Messenger chats?
Yes. Stealth Mode works on both the end-to-end encrypted thread and the migrated legacy thread, on messenger.com and on facebook.com/messages. Unsay never reads or decrypts your messages, it only asks Messenger to remove the ones you sent, in oldest-first order.
How long does Stealth Mode take on a large conversation?
Roughly 6 seconds per message on average, due to the randomized 5 to 7 second delay between each removal. A 1,000-message thread takes about 1 hour 40 minutes. A 10,000-message thread takes about 16 to 17 hours. You can pause, close Chrome, and resume later, the job state survives.
Can I use Stealth Mode in group chats?
Yes. Stealth Mode works the same way in group chats. Only your own messages are removed, and the order is still oldest first. The other participants' messages are never touched.
Is Stealth Mode against Messenger's terms of service?
Stealth Mode uses the same Remove for everyone action Messenger gives you when you long-press a message. It does one removal at a time, with human-like 5 to 7 second pauses, so it stays under Messenger's automated radar. The order in which you delete your own messages is your own choice. That said, you should always check Facebook's terms before automating any action on your account.
Is Stealth Mode free?
No. Stealth Mode unlocks with a Pass: $30 for 7 days or $60 for 30 days (launch prices, regular $60 and $120). Each Pass is a one-time payment with nothing to cancel, it just expires on its own. The free tier removes in the default order, most recent first, up to 50 messages per week. You can install the free extension and unlock Stealth Mode anytime by activating a Pass key from the side panel.
What happens if I close Chrome during a Stealth Mode job?
The job pauses and resumes when you reopen the Unsay side panel. Progress is persisted, so a half-finished cleanup picks up where it left off. If the browser was forced to close mid-removal, the job restarts the next pending message, never re-deleting one that already succeeded.
