In today's digital world, privacy has become a luxury. ziyoupark is driven by a series of simple yet powerful principles:

• True End-to-End Encryption: Using AES-GCM 128-bit encryption, messages are encrypted before sending and can only be decrypted by the recipient holding the correct key
• Complete Anonymity: No personal information is collected — no phone, email, or any authentication required
• No Server Retention: We only act as a temporary relay for encrypted messages; the server cannot read any content
• Keys Under Your Control: Your keys exist only in your browser locally and are never transmitted
• Clear to Disappear: Click "Clear Traces" and all chat history and keys are immediately deleted locally

在当今的数字世界，隐私已成为奢侈品。自由公园由一系列简单而强大的理念驱动：

• 真正的端到端加密: 采用 AES-GCM 128位加密，消息在发送前加密，只有持有正确密钥的接收者才能解密
• 完全匿名: 不收集任何个人信息，无需手机、邮箱或任何身份验证
• 无服务器留存: 我们仅作为加密消息的临时中转，服务器无法读取任何内容
• 密钥由你掌控: 你的密钥只存在于你的浏览器本地，永不传输
• 清空即消失: 点击「清空痕迹」，所有聊天记录和密钥立即从本地删除

ziyoupark uses a pure frontend encryption architecture. Your keys and chat history are stored only in the browser's LocalStorage. When sending a message:

1. The message is AES-GCM encrypted using the recipient's public key (their key)
2. The encrypted message is sent to the server for relay
3. The server cannot decrypt it and only delivers it to the correct recipient based on hash indexes
4. The recipient decrypts locally using their private key (their own key)
5. The entire process ensures: the server does not store plaintext, does not hold keys, and cannot monitor any conversation.

自由公园采用纯前端加密架构，你的密钥和聊天记录仅存储在浏览器的 LocalStorage 中。发送消息时：

1. 使用对方的公钥（即对方密钥）对消息进行 AES-GCM 加密
2. 将加密后的消息发送至服务器中转
3. 服务器无法解密，仅根据哈希索引将消息投递给正确的接收方
4. 接收方使用自己的私钥（即我的密钥）在本地解密
5. 整个过程确保：服务器不存储明文、不掌握密钥、无法监控任何对话。

How to use

1. Open https://www.ziyoupark.com
2. Copy your "My Key" and securely send it to your friend (via another channel)
3. Paste the key your friend sent you into the "Their Key" field
4. Start sending encrypted messages! Each message will show an AES encryption indicator
5. ⚠️ Important: When exchanging keys for the first time, use another secure channel (in person, encrypted messaging app, etc.) to prevent man-in-the-middle attacks.

使用方法

1. 打开 https://www.ziyoupark.com
2. 复制你的「我的密钥」并安全地发送给你的朋友（通过其他渠道）
3. 将朋友发给你的密钥粘贴到「对方密钥」框中
4. 开始发送加密消息！每条消息都会显示 AES 加密标识
5. ⚠️ 重要提示：首次交换密钥时请通过其他安全渠道（如当面、加密通讯软件等）传输，防止中间人攻击。
