这是什么What it is
Seal 是一款 iOS 自签名工具。它帮你用自己的 Apple ID，把应用安装到 iPhone，并保持长期可用 —— 签名、安装、续签，全程在手机上完成，不需要电脑常驻。Seal is an iOS self-signing tool. It installs apps on your iPhone with your own Apple ID and keeps them working — signing, installing and renewing all happen on the phone, with no computer needed afterwards.
它不做这些：不修改 App 内部功能，不解锁任何系统限制，不绕过 App Store 的付费与账号机制。What it does not do: it does not modify apps, unlock any system restriction, or bypass the App Store’s payment and account systems.
免费与更新Free and updates
Seal 完全免费，无广告、无内购、无付费墙，也不售卖任何功能。工具持续更新，最新版本与更新说明见官网首页「更新日志」；使用中遇到问题，可查阅「帮助中心」，或在「讨论区」里提问。Seal is completely free — no ads, no in-app purchases, no paywall, and no paid features. It keeps being updated; the latest version and release notes are in the Changelog on the homepage. If you run into trouble, check the Help Center or ask in the discussion area.
开发与维护Development and maintenance
Seal 由 MJorb 一人开发与维护。服务器、域名与开发成本全部个人承担，没有投资方，也没有商业回报。Seal is built and maintained by one person, MJorb. Servers, domain and development costs are all paid personally — no investors, no commercial return.
这意味着：更新节奏取决于个人时间，回复可能需要等待，也不提供工单式的紧急响应。如果 Seal 确实帮你省了事，写封邮件告诉我哪里好用、哪里难用 —— 比任何评分都直接。That means updates depend on personal time, replies can take a while, and there is no ticket-style emergency response. If Seal has saved you some trouble, write me an email about what worked and what did not — that is more useful than any rating.
