Is there a better way to save levels?

I've been testing my game in the browser while I build it (preview project). I've been using Local Storage to save levels, but yesterday I had to clear the cache in my browser and today I'm back to level 1.

This is not ideal. I now need to play all 22 levels again to check any new levels.

Also, when this game actually becomes an app, will the levels revert back to 1 when the player updates?

But how do I save the levels so they're not cleared with the cache?

Thank you.

You have nothing to worry about when it is on mobile because you must delete app data and doing this is usually a sign you want to delete the app and all save games. When you update the app, the previous save data remains.

Also I believe clearing just cache won't remove the local storage data. You must have cleared "site data" or "hosted app data".
