这是什么应用？
Cipher7 是一款「代号优先、零知识」的密码保险箱。日常界面只显示代号，真实密码与账号按需查看；所有数据以 AES-256-GCM 加密、Argon2id 派生密钥，只保存在你自己的设备上。无需注册账号即可完全离线使用，我们看不到你的任何内容。
常见问题（FAQ）
Q：我忘记了主密码，怎么办？ 创建保险箱时生成的 助记词恢复码（Emergency Kit） 就是你的后备钥匙。打开 App → 在解锁页选择「用恢复码找回」→ 按顺序输入助记词 → 即可解锁并重设主密码。请务必把恢复码离线保存（抄在纸上、存进保险柜）。
Q：恢复码也丢了，能找回数据吗？ 不能。零知识架构意味着只有你能解密数据，我们没有任何后门或备份可帮你恢复。这也是它安全的原因。请妥善保管恢复码。
Q：换新手机，数据怎么迁移？
- 如果开启了 iCloud 加密备份：在新设备登录同一 iCloud，安装 Cipher7，用主密码或恢复码解锁即可恢复。
- 如果使用自托管同步：在新设备填入你的服务器地址并解锁即可同步。
- 也可在旧设备「导出」加密文件，在新设备「导入」。
Q：数据存在哪里？你们能看到吗？ 数据只存在你的设备（及你自己的 iCloud / 自托管服务器）。我们的服务器即使参与同步，看到的也只是加密后的密文，无法解密。
Q：支持系统自动填充 / 验证码（TOTP）吗？ 支持内置 TOTP 动态验证码；系统级自动填充（AutoFill）随版本逐步开放，具体以当前版本为准。
Q：怎么删除我的数据？ 所有数据都在本地。删除 App 即删除本机数据；如开启了 iCloud 备份，请到 iCloud 设置中删除对应备份；如使用自托管，请在你的服务器上删除保险箱文件。
Q：为什么界面只显示代号？ 这是核心设计——防止肩窥。屏幕、历史、剪贴板默认只展示代号，真实内容需生物识别确认后查看，并在 30 秒后自动清空剪贴板。

What is this app?
Cipher7 is a codename-first, zero-knowledge password vault. The everyday interface shows only codenames; real passwords and accounts are revealed on demand. All data is encrypted with AES-256-GCM (keys derived via Argon2id) and stored only on your own devices. It works fully offline with no account required — we can never see your data.
FAQ
Q: I forgot my master password. What now? The passphrase recovery code (Emergency Kit) generated when you created your vault is your backup key. Open the app → choose Recover with recovery code on the unlock screen → enter the passphrase in order → unlock and reset your master password. Keep your recovery code offline (write it down, store it safely).
Q: I lost the recovery code too. Can you recover my data? No. Zero-knowledge means only you can decrypt your data — we have no backdoor or backup to restore it. That is exactly what makes it secure. Please safeguard your recovery code.
Q: How do I move my data to a new phone?
- With iCloud encrypted backup: sign in to the same iCloud on the new device, install Cipher7, and unlock with your master password or recovery code.
- With self-hosted sync: enter your server address on the new device and unlock to sync.
- Or Export an encrypted file on the old device and Import it on the new one.
Q: Where is my data stored? Can you see it? Your data lives only on your devices (and your own iCloud / self-hosted server). Even when our server relays sync, it only ever sees encrypted ciphertext and cannot decrypt it.
Q: Do you support AutoFill / one-time codes (TOTP)? Built-in TOTP one-time codes are supported. System-level AutoFill rolls out progressively by version — refer to your installed version.
Q: How do I delete my data? All data is local. Deleting the app removes on-device data; if iCloud backup is enabled, delete the corresponding backup in iCloud settings; for self-hosting, delete the vault file on your server.
Q: Why does the UI only show codenames? This is the core design — shoulder-surf protection. Screen, history, and clipboard default to codenames; real values require biometric confirmation and the clipboard auto-clears after 30 seconds.
