A person reads every message — probably the person who wrote the code.
We're a small workshop, and some days that means one person. We aim to reply within a few days, and sometimes it takes longer than that — if you haven't heard back, you haven't been forgotten. There's no ticket system and no chatbot: a person reads it, and a person answers.
Tell us which app you're writing about. Each app has its own site, and that's the better place for questions about that app — this address is for the workshop itself, and for anything that doesn't have a home yet.
If you're asking what an app stores about you, the answer is in that app's own privacy policy, linked from the app's site. For this website specifically, see the privacy page for this site.
