"If I leave the group, does all that chat history just vanish?" "Will the other members lose my messages too?" "If I rejoin later, will the old messages come back?"
These are some of the most-searched LINE-group questions, and a lot of people get the actual behavior wrong. Let's clear it up.
Bottom line
| You vs. them | Can you see it after leaving? |
|---|---|
| Your copy of the group chat on this phone | Wiped — gone permanently, can't be recovered inside LINE |
| Your account signed in on a different phone | Also gone (account-level sync) |
| Other members' copies of the chat | Fully intact, including every message you ever posted |
| What you'd see if you rejoined the group later | Only new messages after rejoining — old ones don't come back |
Translation: leaving a group only wipes your own phone's copy. The group's full history still exists, just not for you.
4 common misconceptions about chat history
Misconception 1: "Leaving the group recalls my messages"
No. Leaving is "I'm out," not "undo." Every message, sticker, photo, and file you ever sent to that group stays on every other member's phone. If you want to recall a specific message, use LINE's Unsend feature (available within 24 hours of sending) — that's a completely different action from leaving the group.
Misconception 2: "If I rejoin, my old messages will come back"
No. The moment you leave, LINE actively wipes the group chat on your phone. If you rejoin later, you only see messages from the moment you rejoined onward. Conversations from 2020 don't come back.
The only exception is the LINE OpenChat setting "Show chat history to new members" — if the OpenChat admin has enabled this, you can scroll up and read older messages when you (re)join. Regular LINE groups don't have this setting.
Misconception 3: "After I leave, the other members won't see my old messages anymore"
Wrong. Other members' chat histories are completely unaffected by your exit. Every message you posted, every photo you shared, every sticker you used — they're all still there on their phones. If you're worried about exposed content, leaving the group doesn't help.
The only way to actually remove a message is to Unsend it within 24 hours of sending, and only for messages you sent yourself.
Misconception 4: "I can still see the group from another phone if I sign in there"
No. LINE syncs at the account level — when one device leaves the group, every device signed into that account leaves at the same time. No "leftover" device keeps the chat history.
2 backup steps to do before you leave
If the group contains anything you might need in the future — work decisions, hangout plans, payment receipts, family photos — do these two things before you tap Leave, or you'll lose access permanently.
Step 1: Back up all chats to the cloud
iOS and Android flow:
- Open the group → tap the menu icon (☰ or hamburger) in the top right
- Tap Other settings (or Settings) → Back up chat history
- iOS backs up to iCloud, Android to Google Drive
- Wait for the backup to finish before you leave
WARNING: LINE's cloud backup is account-level, and only restores when you reinstall LINE or switch phones. Backing up doesn't mean you can "still read the chat after leaving" on the same phone — backups are for moving the data to a new device, not for daily reading.
Step 2: Save the specific messages or files you actually need
If you only care about a few specific messages or photos, it's faster to just save those directly:
- Photos/videos: tap to open → Save to your photo library.
- Messages: long-press the message → Keep (LINE's personal Keep cloud storage) or Forward to a 1-on-1 chat with yourself. Keep is your private space and is unaffected by leaving the group.
- Files: tap the file → Save to Files / Drive.
Neither of these requires backing up the entire chat — just the parts you really need, much faster.
After leaving, are there any other ways to recover the chat?
Already left and just realized you needed something? A few possible recovery paths, but none are guaranteed:
| Recovery method | Viable? | Catch |
|---|---|---|
| Restore from cloud backup | Partially | You need a backup from before you left, and you have to reinstall LINE to restore — newer messages may be overwritten |
| Ask a group member to forward the messages | Yes | They're still in the group, they can forward to you one-on-one |
| Check LINE on desktop | No | The desktop client also leaves the group on sync — no leftover history |
| Third-party recovery tools | Not recommended | Mostly marketing fluff; reading the local LINE database is risky |
The most reliable recovery is to ask another group member to screenshot or forward — more dependable than any technical workaround.
Will rejoining restore my old messages?
Many "leave" decisions are impulsive, and a few hours later people want back in to read the old chats.
- Regular group: rejoining doesn't recover old messages — you only see new ones.
- Public LINE OpenChat: you can search and rejoin yourself, but whether you see old messages depends on the admin setting. Most OpenChats don't enable history-on-join by default.
- Private LINE OpenChat: same as regular groups.

Would rather not leave, just "not see it"?
If your goal is just "stop the noise" without losing the chat history, don't leave the group. Use these instead:
- Mute group notifications (long-press the group → notifications off)
- Hide the chat (swipe left on the group → Hide)
- Mute + push to the bottom of your chat list
All your chat history stays intact, the group is visually gone, and you can scroll back any time. Full comparison of all 4 alternatives in the pillar: How to leave a LINE group quietly: 2026 complete guide.
Left the group, but still worried about one person?
If you left because one specific person in the group was ignoring you or avoiding you, after exiting you might still be wondering — has this person also blocked me one-on-one?
LINE hides block status carefully — your one-on-one messages still show as "unread," their avatar still loads, everything looks normal — but nothing reaches them. The only way to confirm is with a tool.
Left the group but still can't shake the feeling? LINE Block Checker signs in once, scans your entire friend list in 5 seconds, and tells you anonymously who blocked you.
Frequently Asked Questions
After leaving, can I find my chat history in the phone's file system?
No. LINE stores group data in an encrypted SQLite database, and on exit the corresponding chat thread is flagged as cleared. Even if the file is still there, the app won't read it anymore.
What happens if the group is dissolved?
"Dissolving" the group is a separate scenario — usually triggered by the admin or when the last member leaves. The entire group disappears from LINE's system. Every member's chat history gets wiped.
Being kicked vs. leaving — is the result the same?
For chat history, yes — both wipe your phone's copy. The difference is only the system message: leaving says "XXX has left the chat," getting kicked says "XXX has been removed from the group."
Keep vs. cloud backup — what's the difference?
Keep is LINE's personal cloud storage. Anything saved there is unaffected by leaving groups and can be read any time. Cloud backup is a snapshot of your entire LINE account, only used when you reinstall or change phones — you can't read it normally.
