Browser Storage and Embedded Scores: What Resets and What Stays

Where browser games actually keep your progress

Most browser games save on your device, not in a cloud account. Local storage is a small per-site bucket your browser sets aside for high scores, unlocked levels, and settings. There is usually no server-side save tied to a login. Progress sticks to one browser on one device.

That one fact covers nearly every "my save disappeared" ticket we get. The data was never on a remote server you could log back into. It lived in the browser you played in. Anything that clears that storage clears your progress.

Why a save lives with the host, not the portal

Games in iframes store data under the host domain that serves the game, not the portal you browsed to. Your score belongs to the game origin. Same host across different portals can remember you. Change the host and you start fresh.

The portal cannot read, back up, or restore in-game progress. The save is between your browser and the game host. We only provide the window.

What a page refresh does and does not reset

Reloading the page reloads the iframe and kills the run in progress. High scores and unlocks usually survive because they were already written to local storage. Losing your active run and losing your save are different events. People mix them up constantly.

Mid-write is the risky window. If a game saves only at level end and you refresh mid-level, that progress may never have been written. Finish the level before you navigate away when a milestone matters.

The settings that quietly wipe everything

"Clear browsing data," "clear site data," aggressive privacy extensions, and private/incognito mode (which discards storage when the window closes) all wipe local storage. None of them announce they are deleting game progress. They still do.

Cross-device disappointment has the same root cause. A high score on your phone will not appear on your laptop. There is no broken sync. The two browsers never shared data.

Protecting scores you actually care about

Local saves are convenient and fragile. Do not treat them as permanent. If a personal best matters, screenshot it. No privacy clear or extension can delete your camera roll.

Play titles you care about in your normal browser, not incognito. Skip cleaner extensions that purge site data on a schedule. Clearing browsing data is a clean slate for games too. Most surprises come from not knowing that.

Why we explain this on detail pages

Save behavior varies by host and trips up players often enough that our editorial copy flags when progress lives locally and may reset. Up-front honesty turns "the game lost my data" into an understood limitation of browser play.

Instant-play portals optimize for trying things in seconds with no install or account. The tradeoff is lightweight, local, occasionally disposable saving. We would rather say that plainly than pretend cloud sync exists when it does not.
