Load Construct 3 and check its About dialog - it tells you the quota available to web pages.
Hi,
On Mac OSX Safari 12.0 (14606.1.36.1.9)
I got this information:
Local storage
Storage quota (approx): (status unavailable)
Storage usage (approx): (status unavailable)
Persistant storage: (status unavailable)
Is it possible for me to get the Local storage information on Mac?
