I always thought that a site that promises true anonymity and has a lucrative set of transparent terms and services for not tracking its users seemed more like a honeypot made by Big Brother.
E.g. when Hushmail was the big deal of the day i got paranoid it might be funded by the NSA, and i don't even have to hide anything.
My online footprint is pretty-much unique and if someone wants he could easily track me etc.
"Hushmail, a longtime provider of encrypted web-based email, markets itself by saying that "not even a Hushmail employee with access to our servers can read your encrypted e-mail, since each message is uniquely encoded before it leaves your computer."
But it turns out that statement seems not to apply to individuals targeted by government agencies that are able to convince a Canadian court to serve a court order on the company."
Also Lastpass and the like - i am afraid of a breach.... I prefer off cloud storing of the kdbs files and manually syncing them or sync them via Drop box, or other third parity cloud service.
