Save System & Data Safety
Where your progress lives, how auto-save works, and how to back it up before switching browsers or devices.
Where your save is stored
Tycoon Cards stores your entire game state in your browser's local storage — a small data store tied to this specific browser and device. No account, email, or server-side storage is involved; your save never leaves your device unless you manually export it.
How auto-save works
The game automatically writes your progress to local storage every few seconds, and again immediately whenever you close the tab or switch away from it. This means you rarely need to think about saving manually — it happens continuously in the background.
Exporting a backup code
- Open the Stats tab.
- Click Export Save.
- Copy the generated code somewhere safe, such as a notes app or password manager.
Importing a save on a new device
- Open Tycoon Cards in the new browser or device.
- Go to the Stats tab and click Import Save.
- Paste your previously exported code and confirm.
What causes save loss
- Clearing browser data or cookies with "site data" included.
- Using private/incognito browsing, which never persists local storage after the session ends.
- Switching browsers or devices without exporting first.
- Extremely rare storage corruption from an interrupted write.
Corrupted save recovery
Every time your save loads, Tycoon Cards runs it through a validation and repair process: any missing or malformed fields are reset to safe defaults rather than crashing the game. In the worst case, a fully unreadable save is treated as a fresh start rather than an error.
Hard reset — what it does
The Hard Reset option in the Stats tab permanently erases your local save and starts a brand-new game. This cannot be undone unless you had previously exported a backup code.

Frequently asked questions
Does clearing cookies delete my save?
+
Does clearing cookies delete my save?
+Your save is stored in browser local storage, not cookies, but many 'clear browsing data' options remove both together. Always check whether local storage is included before clearing data.
Can I play on two devices at once with the same save?
+
Can I play on two devices at once with the same save?
+Not simultaneously. You can move a save between devices using export and import, but playing on both at once will cause the two saves to diverge, and only the last one you save will persist wherever you play last.
Is my save data encrypted?
+
Is my save data encrypted?
+Your save is encoded (not encrypted) for safe transport when exporting, and validated on import to catch corruption — but it isn't designed to be cryptographically secure, since it contains no personal data.
What happens if an import fails?
+
What happens if an import fails?
+The game checks that an imported save is well-formed before applying it. If the code is invalid or corrupted, the import is rejected and your current save remains untouched.
Is there a cloud save option?
+
Is there a cloud save option?
+Not yet — see the Updates page for our roadmap. Currently, all progress lives in your browser's local storage, with manual export/import as the way to move between devices.
How often should I export a backup?
+
How often should I export a backup?
+Any time you've made significant progress you'd hate to lose — after a big prestige, a strong pack-opening session, or before trying a new browser or device.
