Untilum is an open protocol for data that stays confidential until a chosen future date — openable after that date by anyone holding the password, withno permission from, participation of, or continued existence of any organization, this one included. Two independent factors enforce it: a public randomness signature that does not exist before the date, and a password only its owner ever holds.

RFC-0008 §4 requires two interoperating implementations of every mandatory feature before a version finalizes.
What we tell the people who use this
"Your file is encrypted on your device. Opening requires both your password and a public randomness value that will not exist until your chosen date. We never have your password, your key, or your file's contents — which also means we cannot recover them for you. Before the date, nobody — including us, our storage providers, or any single randomness network under the strict policy — can open the capsule. The mathematics, not our goodwill, enforces this."
