what "on your device" actually means (and why it's different)

Before you log your GLP-1 anything in an app, ask one question: where does this data actually live? 'Free tracker with a community feed' and 'stays on your device' are not the same thing, and the difference matters more here than almost anywhere.

Every app says 'privacy-first' and almost everyone scrolls past it, so let me make it concrete, because for this category it actually matters. There are two genuinely different models for how a tracker handles your data. One: you make an account, your entries upload to the company's servers tied to your name, and very often the reason the app is free is that the data, the ads, or an attached commercial offer is the business model.

Two: your entries stay on your device and aren't required to leave it for the core features to work. The quick test is whether you can use the app fully without an account. Now, why does this matter more here than for, say, a habit tracker?

Because GLP-1 logging touches some of the most sensitive data you have — a medication you're on, how your body responds, your weight and your progress. That's precisely the data you'd want to be deliberate about. A free tracker with a community feed isn't really free if the price is that this information lives on someone's server, tied to you, as part of their business.

Maybe that's a trade you're completely comfortable with — but it should be a choice you make on purpose, not a default you didn't read. Where Titra stands on this is simple and it's the whole point of the product, not a bolt-on: your data stays on your device. It's a tracker, not a data business.

Maybe that's a trade you're completely comfortable with — but it should be a choice you make on purpose, not a default you didn't read.

Your dose log, your notes, your progress — yours, on your phone, not shared, not sold. So whatever you end up using, ask the three questions before you log anything sensitive: do I need an account, where does my data go, and how does this app make money. The answers tell you what you need to know.

For something this personal, 'it stays on my device' is a perfectly reasonable thing to want — just worth checking rather than assuming.
