Show HN: Seal - Letters and passwords that open for your family after you die
Seal is an iOS app (iPhone/iPad) that creates encrypted "Envelopes" of passwords, photos, and voice memos for family members, unlocked via hardware keys assigned per person, with a 90-day countdown, 21 days of warnings, and a 14-day grace period before designated recipients gain access. Built on Crypto Kit and CloudKit with no server besides a free Cloudflare static site, it avoids password-manager emergency access by giving each holder their own envelope with no third-party middleman. The app is free on TestFlight, open-source on GitHub, currently unaudited and authored by a CS undergrad with Claude.

score
score 5 out of 10. 0-10: how dense the facts are, multiplied by how much you can do with them after reading. 8+ means the topic's evidence bar is met: benchmarks and availability for a new model, amount and investors for a funding round, revenue figures for a solo-money story. Below 5 an item does not enter the digest. A press release scores 3 or less, a reprint loses 2, anything older than 14 days loses 1, a headline that misleads loses 3.
