> "Woebot has moved away from Facebook and launched as a stand-alone app that only requires a first name to sign up; ... Users can also ask Woebot to delete their account history, wiping all conversations. ... Even when people email us, we're like, 'We don't know who you are!' That was a really clear decision from the outset."

So it sounds like they're doing the right thing. They're helping people with mental health issues so I want to believe good privacy practices will continue.

Time will tell. Until then, this sounds like a wonderful project.

[UPDATE] Okay, I just tried the app. The first thing it asks for is your name. Fine. Pseudonym, no problem. The second request is, "I need to send you a code. What's your phone number?"

So much for "we don't know who you are". >:

[SOLUTION/PSA] Use a service like Twilio for signup. For $1 you can pull a random SMS-compatible phone number out of a pool, get your signup code from the Twilio web console, and then release the phone number. Not anonymous but obscured identity, at least.
