Astro Diner Save Data and Troubleshooting

What is saved

The local save can include diner funds, purchased upgrades, world progress, stars, settings, career stats, mission claims, achievement progress, recipe mastery, personal bests, recent shift history, customer discoveries, and save portability metadata.

The save belongs to the browser profile and device that created it. Astro Diner does not require an account, so export/import tools are the portable backup path when players want to move progress or protect a local save.

Why progress may disappear

Progress may be unavailable if the player uses a different device, switches browser profiles, opens private browsing, blocks site storage, clears browser data, or uses cleanup software that removes local site data.

A browser update or extension can also affect storage. Before assuming a game defect, check whether the same browser profile still has permission to store site data for astrodiner.app.

Export and import

The in-game save tools can create a versioned JSON export with a deterministic integrity hash and a readable summary. Exports intentionally exclude secrets, browser fingerprints, analytics identifiers, ad data, and unrelated local-storage values.

Import first validates the JSON, schema version, integrity hash, known recipe, achievement, and mission ids, then creates a rollback backup before replacing the active signed save.

Basic checks

Reload the page once, then return to the same browser profile where the progress was earned. Check whether storage or privacy settings are blocking local data. If playing on mobile, confirm that the browser is not in a temporary private tab.

If the game is slow, close extra tabs and reload. Astro Diner uses a live React game surface, so older devices may benefit from fewer background tasks during a busy shift.

When to contact support

Contact support when the same browser profile still has storage enabled but the game repeatedly fails to load, cannot start a shift, or loses progress after every normal reload.

Useful details include the device, browser, approximate time, whether private browsing was active, and what happened immediately before the problem appeared.

Troubleshooting examples

A common support case is a player who returns from a private tab or a different browser profile and thinks the save is missing. The guide explains that local browser storage belongs to the profile and device that created the progress.

Another common case is a normal browser cleanup that removes site data. The page tells players what to check before contacting support and what details are useful if the game repeatedly fails to keep progress after normal reloads.
