I'm shooting for updates about once a month at the most, if that answers your question.
Wow nobody usually cares about that, but since you asked, your email address is stored in a database
just like on any site, but is actually stored by us in our own database and not anybody else's. You're probably like "so what?", but keep in mind that most people have their subscriber lists managed by random 3rd party services that can have data breaches or even do slimey ad-tech tracking stuff. I mean so can I, but trusting one person is safer than two. Aytwit also encrypts your email address before saving it, which is beyond what most subscriber list systems do. This means that if a database leak happens the hacker will just get a big list of random data and your email address will be impossible to extract unless the hacker penetrates a separate line of defense as well, the "vault" for the encryption key. It's kind of like locking the house door and turning on the alarm. It won't stop an Ocean's 11 hacker situation but it's two layers of defense that are better than nothing. And it's the most that can be done in an "information-theoretic complexity" kinda way anyway. So you're welcome
