Where high scores go with no login
NoCharge scores live in browser localStorage under the nocharge: prefix. How to find them, why they vanish in private windows, and how to clear them.
Bottom line: NoCharge high scores, best moves, win counts, and progress are stored in your browser’s localStorage under the nocharge: prefix. Nothing is uploaded, nothing is shared, and nothing follows you to another device. The Privacy page lists every key; “Clear game data” removes them.
The exact shape
nocharge:{game}:high— best higher-is-better score (Memory Match, Word Tile Rush, Color Flip, Beacon Lattice).nocharge:{game}:best-moves,best-time,best-length,best-tier— per-game best metrics.nocharge:{game}:games-won,puzzles-solved,puzzles-revealed— lifetime counts on this browser.nocharge:{game}:current-puzzle— in-progress boards for Sudoku 6×6 and 9×9.nocharge:passplay:match:{game}— one most-recent Pass & Play record per game.nocharge:pref:*— sound, volume, ambient, draw mode, theme, size, calm-pattern preferences.nocharge:pref:recently-played— up to four recent game IDs.
How to see them
Open the browser’s DevTools → Application → Local Storage → https://nocharge.net. NoCharge’s own localStorage inspector (when it ships) lists the same keys without DevTools.
Why they “disappear”
- Private window: temporary storage; closing it discards the values.
- Different browser or profile: storage is per origin, per browser, per profile.
- Different device: localStorage never leaves the machine.
- Site data cleared: the values are gone; there is no backup.
How to remove them
Privacy page’s “Clear game data” removes exactly the allowlisted NoCharge keys — not consent, not Google’s advertising choices, not unrelated origin data.
Limits
localStorage is not a durable “save”: it can be evicted by the browser, size-capped, and is per device. NoCharge provides no export, no cloud copy, and no recovery.
