Spare Keys

Dead man's switches for solo developers and one-safe-place-for-your-papers apps are on the front pages this week (Show HN and Product Hunt, Oct 2026). This one keeps no secrets at all.

Leave a spare key, not a puzzle.

If you were out of reach tomorrow - in hospital, off the grid, or gone for good - could someone you trust keep things running? Type what they would need to handle, one thing per line. Each line becomes a key on the cabinet, hung on the day it matters. Keys with a gap stay blank until you fill it. Then seal it all into a letter.

Try one:

1 Your notes

Or drop a .txt file here -

Never type a password here. Write where it is kept. If one slips in, the page removes it before anything is sent and never stores it.

    2 The key cabinet

      3 Cut the keys

      Pricing as soon as the session is ready...
