 - 只有你本人登录这台电脑的这个 Windows 账号时，程序才解得开。
 - 别人就算把配置文件整个拷走，换台电脑也解不开。
 
-::: warning 代价是：换环境就解不开了
-下面三种情况，旧的密码数据会失效，需要你重新填一遍。这不是 bug：
-
-1. **重装系统，或换了新的 Windows 账户** —— 旧账户的密钥没了。
-2. **用非正常手段重置了 Windows 登录密码**（离线改密、系统修复工具改密等）——正常在系统里改密码没问题，绕过系统改就会丢。
-3. **把配置拷到别的电脑或别的 Windows 账户下用** —— 加密数据只在原来那台电脑的原账户下有效。
+::: warning 警告
+  在以下情况下，系统可能无法解密原有数据：
+
+  1.  **更换或重装系统**
+      如果您重新安装 Windows 或使用新的电脑账户，原账户的加密密钥将丢失，程序将无法读取旧数据。
+  2.  **删除或重置用户账户密码**
+      DPAPI 的加密密钥与您的 Windows 登录凭据绑定。
+      如果您使用非正常方式重置密码（如离线修改、系统修复工具修改等），Windows 无法重新解密旧的加密文件。
+  3.  **复制数据到其他电脑或账户**
+      DPAPI 加密的数据仅在原账户和计算机上有效。复制配置文件到其他环境时，数据会因密钥不匹配而无法解密。

 - The app can only decrypt the data while you are signed in to that Windows account on that computer.
 - Even if someone copies the whole config folder, they can't decrypt it on another computer.
 
-::: warning The tradeoff: change environments and it can't be decrypted
-In the three cases below, your old credential data stops working and you'll have to enter it again. This is not a bug:
-
-1. **You reinstalled Windows, or switched to a new Windows account** — the key from the old account is gone.
-2. **You reset your Windows login password by bypassing Windows** (offline password editors, system repair tools, and the like) — changing your password normally from inside Windows is fine; going around Windows to do it loses the key.
-3. **You copied the configuration to another computer or another Windows account** — the encrypted data is only valid under the original account on the original computer.
+::: warning Warning
+Existing data may fail to decrypt in the following cases:
+
+1. **Changing or reinstalling the system**
+   If you reinstall Windows or use a new computer account, the encryption key from the original account is lost and the app cannot read old data.
+2. **Deleting or resetting the user account password**
+   DPAPI encryption keys are bound to your Windows login credentials.
+   If you reset the password abnormally, such as through offline modification or system repair tools, Windows cannot decrypt old encrypted files.
+3. **Copying data to another computer or account**
+   DPAPI-encrypted data is valid only on the original account and computer. Data copied to another environment cannot be decrypted if the key does not match.
