Promise Ledger

Write a commitment and seal it with a hash. Change one character later and verification fails — a tamper-evident record only you hold.

4 sealed2 open1 kept50% keep rate
?
keep rateOf the promises you have resolved, the share you marked kept rather than broken — that is, kept ÷ (kept + broken). It ignores promises that are still open. Shows “—” until you resolve at least one.
1 overdue
?
overdueOpen promises whose deadline has already passed (compared in UTC). Mark them kept or broken to clear this.

Seal a new promise
?
sealA seal is the SHA-256 fingerprint of your exact words plus deadline. If even one character changes later, the fingerprint changes — so the seal proves what you actually wrote.

Write your promise, then seal it.
