Same problem here.
Started new simple wallet (using nanowallet 1.3.3, mac os and safari) Small test transfer from Polo. Works. Put in all my Xem from Polo. Wrote down pw. Logged out.
Tried to log back in. Oops - safari didn't download a .wlt file, also didn't download an 'unknown' file. Safari also forgot about the local cache file (basically as soon as the window is closed).
I wish I'd used Firefox - that does download the .wlt file. Stupid safari doesn't.
tried creating another wallet for testing. Safari really doesn't appear to storing anything anywhere. Nothing appears in the user/safari folder. A few large history files do update, but doesnt seem like wallet file/private key can be retrieved from there.
or it's exceedingly difficult.
Any ideas about retrieving the wallet file from somewhere inside my computer? I suppose it just hasn't been stored anywhere.
I feel so dumb, of course I need a private key - should have written that down too. And to think I was transferring my XEM in order to be safe (safer than in the exchange). Should have read the instructions more carefully. But I didn't expect to loose all practically immediately after logging off. So odd that the wallet really does not seem to be stored anywhere. Or is it?
So - I feel pretty bad. I wasn't careful enough. lost hard-earned money.
But Safari seems unsafe for using with Nanowallet...
