No. We don't ask for or store a phone number, email, real name, or location. We run no analytics, ads, or behavioural tracking, and we never see your message content. To deliver messages, our database stores basic routing information every messenger needs — which accounts share a conversation, and message timestamps — which we never sell or profile. Push notifications strip all content; only an opaque wake signal reaches Apple's servers. Beyond that, we hold only your username, an opaque push token, and your subscription status.
