  2. 2 · 本地派生密钥：钥匙在设备上生成。2 · Keys derived locally — on your device.
  3. 3 · 只有密文上云：服务器读不到明文。3 · Only ciphertext leaves — the server can’t read it.

诚实提醒：忘记密码可用助记词恢复，但服务器无法替你找回。 Honest note: a recovery phrase restores access — the server cannot recover it for you.

服务器能看到我的文件吗？Can the server see my files?

不能。文件内容、文件名、目录结构都在你的设备上加密后才上传。No. Content, names, and folder structure are encrypted on your device before upload.

忘记密码怎么办？What if I forget my password?

用注册时保存的助记词恢复。请离线妥善保存——服务器无法找回。Restore with the recovery phrase saved at sign-up. Keep it offline — the server can’t recover it.
