Privacy Policy

This page explains how Sudoku Builder handles your information. We aim to collect as little as possible.

Data we store

Sudoku Builder does not require an account and does not run a user database. Your chosen theme is saved in your browser's local storage on your device only. Custom puzzles are encoded into share links — they are not stored on any server.
