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 verified by whom?
Plenty of apps display a reassuring “Data Not Collected” label. The problem is that the claim is unverifiable. You’re trusting a screenshot.
The stronger pattern is the one privacy-serious software has used for years: keep the data on the device, encrypt it there, require no account, and build the app so its privacy can actually be checked. That’s the standard we hold ourselves to.
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.
