Why your GLP-1 data shouldn't live on someone else's server
Your titration schedule and weight aren't just numbers; they're sensitive medical information. Here's why where you track matters as much as what you track.
When you start a GLP-1, you start generating a quietly revealing record: your starting weight, your titration steps, the days you felt nauseous, the weeks the scale didn’t move. Most tracking apps treat that record as theirs. We think that’s backwards.
What your protocol actually reveals
Taken together, your dose history and weight trend say a lot about you, your health, your habits, even your prescription source. That’s information you might not want available to:
- an employer wellness platform,
- your insurer at renewal time,
- or any company holding it on a server you don’t control.
None of that is hypothetical. Health data is bought, sold, breached, and subpoenaed all the time. The safest data is the data that was never collected in the first place.
“Data not collected”, but how would you know?
Plenty of apps show a reassuring “Data Not Collected” label. It is worth more than a marketing sentence, because it is a declaration filed with Apple and Google that the developer is accountable for. But it still isn’t something you checked yourself.
You can check it yourself, though, and it takes about ten seconds.
Turn on airplane mode and use the app normally. If everything still works, there was nothing on the other end to begin with. If it stalls, asks you to reconnect, or quietly stops saving, you have learned where your data actually lives. On iPhone you can go further: Settings, then Privacy & Security, then App Privacy Report, which lists every domain an app has contacted. An app with no server has an empty list.
That test works on any app, including this one. Run it on whatever you are using now.
What “on your device” really means
With Lirea, there’s no sign-up and no server in the middle. Your doses, weight, and notes are stored — encrypted — on your phone. We don’t have a copy, so there’s nothing for us to leak or sell.
Your weight, your titration, your side effects — none of it on anyone’s server.
It’s a simple promise, and it’s the whole point. Track everything you need to track. Keep all of it yours.
