half-locket, a time-locked envelope for photos and notes

Field notes

The workflow packages photos, videos, and an optional note into a locket with an exact future opening time, using the visitor’s local time and allowing dates up to ten years ahead. Its unusual control scheme separates a cancel card from a second key half: the former can destroy the package before opening, while the latter must be kept or deliberately sent depending on who should control access. The page also offers a mode with no server involvement at all.
