I want to talk about something that doesn't get discussed much in hobbyist circles: what actually happens to the data you log.
Most of us don't think about it. We download an app, start recording our sightings or sessions or whatever we're tracking, and get on with the hobby. The app is convenient. It syncs across devices. It just works.
Until it doesn't.
The Problem With Convenient
I've watched services I relied on change their pricing overnight. I've seen apps go into maintenance mode with six weeks notice. I've heard from fellow spotters who lost years of records because a platform shut down and the export function didn't work properly — or didn't exist at all.
This isn't a rare edge case. It's just the nature of software businesses. They need revenue. When the model changes, the users feel it. And if your data is locked in their format on their servers, you have very little recourse.
The alternative is to own your data from the start.
What Ownership Actually Looks Like
I built AirTrack Solutions around a simple idea: your data lives on your hardware. Not my servers, not a cloud provider's servers — yours. A Raspberry Pi in your home runs the software, stores the database, and serves the app to your devices.
This applies to all three of our products. AirTrack for aviation spotters. TrainTrack for railway enthusiasts. BoxTrack for parcel tracking. Same philosophy across all of them.
When you own the hardware, you own the data. There's no subscription that can lapse and lock you out. There's no company decision that can delete your history. The database sits on your Pi and you can back it up, export it, or move it whenever you like.
It's Not As Hard As It Sounds
The most common reaction I get when I describe this setup is "that sounds complicated." And I understand why — running your own server sounds like something for IT professionals.
But a Raspberry Pi costs about $80. Docker, which is what AirTrack runs on, handles most of the complexity. If you can follow a set of instructions and type a few commands into a terminal, you can have AirTrack running in an afternoon. We've written the documentation to make that as straightforward as possible.
The tradeoff is real — this isn't a zero-setup cloud app. But what you get in return is something no cloud app can offer: complete control over your own hobby records, for as long as you want to keep them.
A Note On TrainTrack and BoxTrack
AirTrack gets most of the attention because aviation spotting is such a popular hobby, but the same principles apply to TrainTrack. If you're a railway enthusiast who logs locomotive sightings, depot visits, or rolling stock details, you deserve the same ownership over that data as any aircraft spotter does.
BoxTrack is a bit different — it's an Android app for tracking parcels — but it follows the same offline-first philosophy. Your tracking data stays on your device.
The common thread is that your hobby is yours. The records you keep should be too.
If that resonates with you, take a look at what we've built on the AirTrack and TrainTrack pages, or check out pricing to get started.
