痛点：遗嘱公开导致数字密码和加密资产无法安全传承，需要一种在死后才能解封的安全传递方式。

目标用户：拥有数字资产（如加密货币、银行账户）并希望在其去世后安全传递给信任的人的用户。

证据：A will filed for probate becomes a public court record. Anyone can read it. So the password to your bank, the code to a safe, the seed phrase to a crypto wallet: none of that can legally go in one.

变现：订阅制（如每年$20-50）或一次性买断，提供多封信件和加密存储。

MVP：使用现有加密库（如libsodium）和iOS的Secure Enclave，实现本地加密信件，设置可配置的未活动天数触发，并通过Face ID或硬件密钥验证。先不做多人复杂通知，仅通过邮件或短信提醒。2周内可做出核心功能原型。

竞品：1Password Emergency Access、Bitwarden Emergency Access、Google Inactive Account Manager、SecureSafe、Everplans

摘要：一名开发者发布了iOS应用Seal，用于在用户去世后安全传递密码和信件。因遗嘱公开无法放入敏感信息，应用通过设定未活动天数后解锁密封信件，支持Face ID和硬件密钥。目前处于TestFlight测试阶段，尚无付费模式。
