由于Telegram提供的功能比任何其他消息传递应用程序(messaging app)都多，因此该平台上的消息管理(message management)可能会更复杂一些。如果您还希望将消息从Telegram(Telegram)的服务器中 删除，那么像从聊天中删除消息这样的普通任务会变得更加困难。
我们将向您展示在Telegram上删除消息的所有方法，无论是与您的朋友或同事(friend or colleague)的常规聊天，还是与许多用户的群聊。
Telegram 如何存储您的消息历史记录(How Telegram Stores Your Message History)
如果您最近出于安全和隐私原因从其他(security and privacy reasons)消息应用程序(messaging app)切换到Telegram，您首先需要了解Telegram如何存储您的聊天记录，以及如何删除它。
您可以在Telegram上进行两种不同类型的聊天：普通或云聊天，以及秘密聊天。云(Cloud)聊天是您与其他用户、群聊和公共频道之间的聊天。它们存储在云端(stored in the cloud)，让您可以在不同设备上无缝使用Telegram，因为您的聊天记录可以轻松下载。根据Telegram的说法，云聊天使用存储在不同司法管辖区的多个数据中心的加密密钥进行加密。
但是，如果您想消除聊天被解密或拦截的可能性，您应该在Telegram上选择秘密聊天而不是云聊天。秘密(Secret)聊天是端到端加密的（仅在您和收件人之间），并且根本不会上传到服务器。
如何删除 Telegram 上的云聊天消息(How to Delete Cloud Chat Messages on Telegram)
如果您不希望您的消息存储在云中，您可以轻松地将它们从聊天中删除。您可以从任何一对一聊天和任何设备中删除消息。您可以删除您发送的消息和收到的消息。无论您多久前发送或接收消息 -(message –)没有时间限制(time limit)。
要从Telegram 聊天(Telegram chat)中删除消息，请按照以下步骤操作。
- 打开电报并选择一个聊天。
- 找到您要删除的消息。选择(Select)并按住消息。
- 选择删除(Delete)。
- 您可以选择只为您或收件人删除邮件。
- 选择删除(Delete)以确认。
完成后，消息将从您的设备中消失，或者从您和收件人的设备以及Telegram 服务器(Telegram server)中消失。
如果您的聊天中有超过 2 个参与者，您仍然可以删除您已经从每个人的设备发送的消息。但是，有时间限制(time limit)。您只能在发送消息后的 48 小时内执行此操作。48 小时后，您仍然可以删除您的消息，但只能从您的设备中删除。该消息将保留在其他参与者的设备以及Telegram 服务器上(Telegram server)。
这同样适用于使用5.5(version 5.5)之前的旧版本Telegram的(Telegram)Telegram用户。在这种情况下，即使是一对一聊天，也适用 48 小时规则，之后您将无法删除所有人的消息。
如果自您发送消息以来已过去 48 小时，则完全删除它的唯一方法是要求收件人（或多个收件人）从他们的设备中删除您的消息。之后，该消息也会从Telegram 服务器(Telegram server)中消失。
如何删除秘密电报聊天中的消息(How to Delete Messages in Secret Telegram Chats)
如果您追求完全的隐私，请考虑在Telegram中使用秘密聊天而不是普通的云聊天。要与某人进行秘密聊天，请在Telegram上选择他们的用户名，然后选择更多(More)（右上角的三个垂直点）>开始秘密聊天(Start Secret Chat)。
在密谈内部，删除消息的过程与上述相同。但是，如果您将消息设置为自毁，则可能不需要它。打开秘密聊天并选择(chat and select) 更多(More)。然后选择设置自毁计时器(Set self-destruct timer)。然后，您可以选择收件人在消息从聊天中消失之前的时间。
使用自毁计时器，消息将在(self-destruct timer)设定的时间(set time)后自动从您的秘密聊天中消失。它们也会从其他人的设备以及Telegram 服务器(Telegram server)中消失。
如何从电报聊天中自动删除消息(How to Auto-Delete Messages From Telegram Chats)
秘密聊天并不是您可以将消息设置为自毁的唯一聊天。您可以在Telegram(Telegram)上的任何聊天中将您的消息设置为在一段时间后自动消失。要启用自动删除功能，请按照以下步骤操作。
- 打开电报并选择一个聊天。
- 在 Android 上，选择更多(More)>清除历史记录(Clear History)>自动删除此聊天中的消息(Auto-delete messages in this chat)。
- 在 iOS 上，选择并按住聊天中的任何消息。从出现的菜单中，按照路径选择(Select)>清除聊天(Clear chat)> 启用自动删除(Auto-Delete)。
您可以选择在 24 小时、7 天或 1 个月后在您发送消息后消失。
如何删除 Telegram 中的整个聊天记录(How to Delete Entire Chats in Telegram)
如果您想摆脱Telegram上的整个对话，请打开应用程序并选择它。然后选择屏幕顶部的bin 图标。(bin icon)您将看到一条弹出消息，询问您是只想为自己删除聊天，还是为您和收件人删除聊天。如果您选择后者，聊天将从您的设备和Telegram 服务器(Telegram server)中消失。
不要忘记推送通知(Don’t Forget About Push Notifications)
能够在您发送消息后从其他人的设备中删除消息，这可能使您不必稍后再解释自己。该功能类似于Gmail Unsend，当您错误地向某人发送消息时，它是一个救命稻草。
但是，不要忘记，虽然您可以阻止收件人看到您的消息，但您不能在他们的设备上禁用推送通知。当您向某人发送消息时，它会显示在他们的通知中。根据他们的设置，即使您已将其删除，收件人也可能会看到您的邮件内容。即使您的消息不会出现在Telegram中，用户也可以截取通知并以这种方式保留您的消息副本。
永远摆脱你的电报消息(Get Rid of Your Telegram Messages for Good)
对于那些想要从Telegram中删除所有消息的人来说，最后一个选择是完全删除他们的帐户。如果您不希望Telegram存储您的任何消息的副本，请确保您也删除了您自己和其他用户的所有对话。

How to Delete Messages on Telegram
Since Telegram offers more features than any other messaging app, message management on this platform can be a bit more complex. Such a mundane task like deleting your messages from a chat becomes more difficult if you also want your messages gone from Telegram’s servers.
We’ll show you all of the ways that you can delete messages on Telegram, whether it’s in a regular chat with your friend or colleague, or in a group chat with many users.
How Telegram Stores Your Message History
If you’ve recently switched from a different messaging app to Telegram for security and privacy reasons, you first need to understand how Telegram stores your chat history, as well as how you can erase it.
You can have two different types of chats on Telegram: normal or cloud chats, and secret chats. Cloud chats are the chats between you and other users, group chats, and public channels. They’re stored in the cloud, which allows you to seamlessly use Telegram on different devices, since your chat history can be easily downloaded. According to Telegram, cloud chats are encrypted with encryption keys stored in several data centers in different jurisdictions.
However, if you want to eliminate the possibility of your chats being decrypted or intercepted, you should choose secret chats over cloud chats on Telegram. Secret chats are end-to-end encrypted (between only you and the recipient) and are never uploaded to a server at all.
How to Delete Cloud Chat Messages on Telegram
If you don’t want your messages to be stored in the cloud, you can easily delete them from the chats. You can delete messages from any one-on-one chat, and from any device. You can delete both the messages you sent, and the messages you received. It doesn’t matter how long ago you sent or received the message – there’s no time limit.
To delete messages from a Telegram chat, follow the steps below.
- Open Telegram and select a chat.
- Find the messages you want to delete. Select and hold the message.
- Select Delete.
- You can opt to only delete the message for you, or for the recipient as well.
- Select Delete to confirm.
When you’re finished, the message will be gone from either just your device, or from both your and the recipient’s devices, as well as the Telegram server.
If your chat has more than 2 participants in it, you can still delete the messages that you already sent from everyone’s devices. However, there’s a time limit. You can only do it within 48 hours after sending the message. After those 48 hours, you can still delete your message, but from your device only. The message will remain on other participants’ devices, as well as on the Telegram server.
The same applies to Telegram users who are using an old version of Telegram prior to version 5.5. In that case, even if it’s a one-on-one chat, the 48-hour rule applies, and you won’t be able to delete the message for everyone afterwards.
If 48 hours have already passed since you sent the message, the only way to completely erase it is to ask the recipient (or recipients) to delete your message from their devices. After that, the message will also disappear from the Telegram server.
How to Delete Messages in Secret Telegram Chats
If complete privacy’s what you’re after, consider using secret chats in Telegram over the normal cloud chats. To open a secret chat with someone, select their username on Telegram, then select More (three vertical dots in the upper-right corner) > Start Secret Chat.
Inside the secret chat, the process of erasing messages is the same as described above. However, you might not need it if you set your messages to self-destruct. Open the secret chat and select More. Then select Set self-destruct timer. You can then choose how long the recipient will have until the message disappears from the chat.
With the self-destruct timer, the messages will automatically disappear from your secret chat after a set time. They’ll also disappear from the other person’s device, as well as from the Telegram server.
How to Auto-Delete Messages From Telegram Chats
Secret chats aren’t the only chats where you can set your messages to self-destruct. You can set your messages to automatically disappear after a certain period of time in any chat on Telegram. To enable the auto-delete feature, follow the steps below.
- Open Telegram and select a chat.
- On Android, select More > Clear History > Auto-delete messages in this chat.
- On iOS, select and hold any message in the chat. From the menu that appears, follow the path Select > Clear chat > Enable Auto-Delete.
You can choose your messages to disappear either after 24 hours, 7 days, or in 1 month after you send them.
How to Delete Entire Chats in Telegram
If you want to get rid of an entire conversation on Telegram, open the app and select it. Then select the bin icon on top of the screen. You’ll see a pop-up message asking whether you only want to delete the chat for yourself, or for both you and the recipient. If you choose the latter, the chat will disappear from both your devices and from the Telegram server.
Don’t Forget About Push Notifications
Being able to delete a message from someone else’s device after you have already sent it can potentially save you from having to explain yourself later. The feature is similar to Gmail Unsend, and is a lifesaver when you send a message to someone by mistake.
However, don’t forget that while you can prevent the recipient from seeing your message, you can’t disable push notifications on their device. When you send a message to someone, it’ll appear in their notifications. Depending on their settings, the recipient might see the contents of your message even if you already deleted it. Even though your message won’t appear in Telegram, the user can take a screenshot of the notification and keep a copy of your message that way.
Get Rid of Your Telegram Messages for Good
One final option for those who want to erase all of their messages from Telegram is to delete their account completely. If you don’t want Telegram to store copies of any of your messages, make sure you also delete all of your conversations for yourself and for other users as well.
