IMO, Privnote is fucking awesome. Easy to use and I don't have to worry about PGP codes and blah blah blah.
But my question is......Is Privnote trustable? With all the occurrences of websites like TOR mail being compromised, is this something you trust?
If not, I guess i should continue using PGP for small messages as well.
Absolutely not! Do not use privnote for anything important. There is no guarantee that they are not recording everything. The server is based in the US. They could be under a court order, like Lavabit was, to hand over the HTTPS encryption keys or to backdoor their system in other ways.
Do not use igolder.com for PGP for the same reasons.
Stay free use PGP!
