My app has no accounts, so I have no way to talk to the people using it

I'm a solo developer in Japan. My app records meetings and transcribes them entirely on your Mac, and there is no sign-in and no account anywhere in it, because the whole point is that nothing about your meetings leaves the machine. I launched it on Product Hunt three weeks ago. 123 people have downloaded it since then, 2 of them bought a license, and I cannot contact the other 121.

I knew there would be no accounts when I started building. I didn't think about what that would mean the first time I wanted to ask somebody why they didn't buy.

So the only users I can hear from are the ones who chose to speak. That turned out to be the comment thread on the launch, and I have been living off it since. Someone pointed out that my whole pitch is that no bot joins the call, but the bot in the participant list is also the thing that tells the room a recording is happening, and I had removed that without adding anything instead. He was right. Four days later I shipped a button that copies a heads-up message into the meeting chat. Someone else lost a recording when they switched from speakers to AirPods mid-call, and that got fixed the same week. Two people asked for Obsidian and markdown, so I built a command line tool. Another asked for search that works on meaning instead of exact words, and that shipped eleven days later.

None of that came from analytics. All of it came from about fifteen people who typed something under my launch. Product Hunt is still sending me traffic three weeks later, mostly because I keep posting updates there, and the comments on those are the closest thing to user research I have.

The problem is obvious. The people who comment are not the people who quietly delete the app, and those are the ones I need. Here are the numbers for the last three weeks. Roughly 800 pageviews on the site, 123 downloads, 50 people opened the buy page, and 2 bought at $49. The trial is 14 days and it starts the first time you record, not at download, so some of those people have not hit the paywall yet. I know 121 people are missing and I know nothing about any of them.

I have thought about putting an email field on the download. It doesn't actually break the promise, because the promise is about meeting content and not about my mailing list, but it would cost me downloads and it would feel like a bait to me. I have thought about an in-app "why are you leaving" prompt, which only reaches people who bother to answer, which is the same fifteen people again.

quickquill.app if you want to look at it. If you sell something that deliberately collects nothing, how do you find out why people don't buy?
