I recently closed my Coinbase.com account permanently. Or tried to. I demanded they erase all record of my data they have on their servers (except for transactions, duh, because they are on the blockchain), and they told me they planned on keeping my data for FIVE YEARS. I told them they'd be hearing from my lawyer. (Not sure if I actually want to go down that legal road yet, but I do know I'll never be talking to, or using Coinbase again.)
I've recently closed my BitPay account, too, and have asked them to delete all my data, also. BitPay is behaving more intelligently than Coinbase. They're "looking into it" and taking their time with my request (while sending me little updates letting me know that they're seriously working on it) instead of just telling me that they are going to keep my data for the duration of the life of a guinea pig. Bear in mind, though, I don't recommend you use BitPay - they are one of the supporters of the Windhover proposal to regulate your digital identity (because hey, let's discard any hope of freedom, because a bunch of companies controlling your identity in line with the corporation-state regulatory interests is so much more preferable! **sarcasm**)
In case you are wondering, yes, I posted this:

I'm currently using Electrum and OpenBazaar for BTC (and some other things that are not reliant upon websites), and am transitioning a good portion of my BTC to BCN (which has a good degree of anonymity, in the context of its Cryptonight algo and schnorr ring signature process), until such time that Zerocash is released (
http://zerocash-project.org/ for those interested, anticipated release is sometime in December 2014 or January 2015, at the moment).
BTW, for those tracking WebCrypto issues (you know, for those that are still working on handling issues relating to decentralized crypto in your browser instead of in a P2P app), the W3C just (finally) opened up to inclusion of both Curve25519 and secp256k1 in WebCrypto ~ the Curve25519 request was originally made by someone (Matt Corallo, specifically) from Open Whisper Systems and TextSecure. Link to some of that discussion is here:
https://www.w3.org/Bugs/Public/show_bug.cgi?id=25839 A variant of Curve25519 is used in BCN. For the other, secp256k1, which is used in bitcoin, a good description came from Hal Finney (R.I.P.) which he posted in bitcointalk, in which he described sec256k1 as "a variant on a so-called Koblitz curve, and 1 means it is the first (and only) curve of that type in the standard." In that same bitcointalk thread where Hal Finney made those remarks, the user ByteCoin in January of 2011 stated, "One plausible option for a future bitcoin-like system is to allow a selection from a numbered range of pre-selected curves. Smaller transactions or balances could use smaller keysizes if necessary." [[ ByteCoin is associated with development of BCN, which uses the Cryptonight algorithm (based from CryptoNote with adaptive limits) / a schnorr ring signature in the Curve25519 group ~ and has received favorable remarks from some bitcoin developers. ]]
Maybe a short way of saying all this is as follows:
Screw you, Coinbase! We're going trustless.
Admittedly TL;DR, but if you made it this far: Disclosure: I am a candidate for an Individual Director seat for the Bitcoin Foundation (election is in Jan. 2015), nominated by Mike Hayes and Jon Matonis.
