Show HN: Seal – Letters and passwords that open for your family after you die

I'm a CS undergrad who has developed an interest in hardware keys ever since I used them for a school project a few years ago. I made a little chat app that only allows users to chat if they registered a key, nothing else. The backstory of how I came to work on Seal (this project): was that I was generating ideas with Claude to come up with an idea that only hardware keys could make into software.

痛点：人们担心自己去世后，密码、照片、遗言等数字资产无法安全、可控地传给家人；现有方案多依赖平台账号或云端托管，缺少实体密钥与本地控制感。

目标用户：注重隐私与安全的个人、加密货币持有者、有家庭数字资产或敏感账号需要传承安排的人。

证据：Seal is an iOS app for iPhone and iPad that lets you write an Envelope (an encrypted bundle of passwords, photos, voice memos, etc...) for all of your loved ones when you're gone.

变现：一次性买断或订阅制，如 5-10 美元/月、50-100 美元终身版；可加家庭计划、硬件密钥套装、白标/律所合作。

MVP：2 周内做一个简化 Web/iOS MVP：用户写加密信件并附密码/文件，设置定期 check-in，超时后向指定受益人发送解密链接；先不集成硬件密钥，用 passkey 或 2FA 替代。

竞品：Google Inactive Account Manager、Apple Digital Legacy、1Password Emergency Access、Bitwarden Emergency Access、LastPass Emergency Access、Dead Man's Switch 类服务

摘要：一名 CS 本科生发布 Show HN 项目 Seal，一个 iOS 应用：用户可用硬件密钥把加密的密码、照片、语音备忘录等装进信封，在长期不登录后按 90 天倒计时、21 天警告、14 天宽限期逐步向家人开放。HN 热度较低，仅 9 分 3 评论，且正文没有收入或明确付费意愿数据，但数字遗产与硬件密钥结合的方向有真实痛点和独立开发可行性，竞品较多。
