There is no advertising tracking, no ad networks, no third-party marketing pixels and no selling of data. What does run is Vercel Analytics & Speed Insights, and it is worth saying exactly what that is rather than hiding it behind the word “private”.
It measures technical performance: how quickly a page loads and renders on your device, which screens are slow, whether something errored, and rough device and browser class so we can tell a slow phone from a slow server. It is how we find out that, say, the Zakat screen is sluggish on older Androids before you have to tell us.
It uses no cookies and no fingerprinting, builds no profile of you, and is never joined to your account. It never sees a balance, a transaction, a metal weight or a Zakat figure. Those live behind your login and are not part of what it measures.
Separately, the app keeps a handful of anonymous counters, such as how many people finished setup. No personal information is attached to those either.
