Great work and not to hijack – are there catalogs of “privacy focused” apps that don’t collect data or make remote requests? I would love a “
Kosher” badge like OU that tells me it’s a simple app (like yours) that provides utility without snooping
Using resources like F-Droid can help you find open source apps, which generally speaking, are very privacy friendly. I believe admittance into the default F-Droid repo doesn't allow trackers at all. Certain alternative front ends to the F-Droid repos, like Neo Store, can display privacy "scores" for individual apps.
There's also many groups that produce privacy-friendly apps, such as SECUSO[0] and Fossify[1]
