About the project

Add an anonymous result and difficulty rating to the public, aggregate research dataset.

We send only this answer word for puzzle verification, the puzzle number, result, difficulty vote, Hard Mode flag, timezone and a random one-puzzle receipt token. The Observatory stores no answer word, grid, guesses, account, email, IP-derived ID or reusable player identifier. The puzzle-specific receipt prevents duplicate submissions and permits withdrawal; anyone with that token can withdraw, so keep browser-data exports private. See the privacy details.
