账号与授权 / Account & Licensing
中文
注册与购买
使用邮箱验证码注册；密码为 12–128 个字符。每款软件单独购买，雷达和触摸桌新购默认各 2 个绑定名额，实际以账号显示为准。请联系支持确认购买，当前没有在线支付。
在线绑定
在对应电脑的客户端登录后绑定或解绑。在线与离线共用该软件的名额，在线解绑成功后返还名额。在线绑定默认永久有效；限时项目可在首次绑定时填写天数，从签发时计算。账号前端可以修改项目期限，目标客户端需联网同步。已发出的旧凭据持续离线时仍可能按原期限使用；首次交付限时项目时请提前设置。到期不自动返还名额。两款正式客户端的新 SDK 接入仍在进行。
永久离线授权
从目标电脑的对应软件导出设备请求 JSON，登录用户中心选择软件并上传文件。核对设备名和完整机器指纹，阅读警告并勾选确认后创建，再把授权文件导回原电脑。
创建将永久占用 1 个名额。创建后不可解绑、撤销或返还名额，即使以后联网登录也不例外。卸载、删除文件或更换电脑不会恢复名额。
重复下载与安全
同一份授权重复下载不重复扣名额。限时凭据检查签名期限、时钟回拨和运行计时，但不能保证防止整机备份恢复。授权绑定机器和安装公钥；重装系统或丢失密钥后可能无法恢复，请先备份并联系支持，不承诺换机恢复。
退出不等于解绑。网页不持久保存密码或会话令牌，刷新后需重新登录。通过邮箱验证码重置密码；不要把密码或私钥发送给支持。

Registration and purchases
Register with an email code and a password of 12–128 characters. Products are purchased separately. New Lidar and Touch Table licenses each default to two binding seats; your account shows the actual allowance. Contact support to purchase; no online checkout is provided.
Online bindings
Bind or unbind from the client on the corresponding computer. Online and offline bindings share that software's seats. Online unbinding returns a seat. Online bindings default to perpetual validity. For limited projects, set the days during initial binding; time starts at issuance. Account changes require the target client to synchronize online. Previously issued offline copies may retain their original validity. Expiry does not return a seat. New SDK integration into both production clients is still in progress.
Permanent offline licenses
Export a device request JSON from the matching software on the target computer. Choose the software in your account, upload the request, verify the device name and full fingerprint, read the warning and confirm. Import the resulting license on the original computer.
Creation permanently consumes one seat. It cannot be unbound, revoked or returned to the balance, even after signing in online. Uninstalling, deleting files or changing computers does not restore a seat.
Downloads and security
Downloading the same license again does not consume another seat. Limited credentials check signed expiry, clock rollback and runtime elapsed time, but cannot guarantee protection against whole-system snapshot restoration. Licenses are tied to the machine and installation key. Reinstalling or losing the key may prevent recovery. Back up and contact support first; transfer is not promised.
Signing out does not unbind a device. Passwords and session tokens are not stored persistently in the browser; refresh requires signing in again. Reset passwords using an email code. Never send passwords or private keys to support.
