Why lock Secret Diary-Gratitude Journal?
Secret Diary-Gratitude Journal is a journal & diary app, the kind of app that tends to hold personal information you would not want on screen if someone borrows your unlocked phone. Journals collect your private thoughts, moods and often your location and photos. A lock screen inside the app is not the same as encryption of the synced entries.
Utilities range from calculators to VPNs, so their labels vary more than any other category. A simple tool that collects identifiers and usage data for tracking is a sign of advertising SDKs.
A lock answers one question — who can open the app on this iPhone. It does not change what Secret Diary-Gratitude Journal sends to its developer; for that, see Secret Diary-Gratitude Journal's full privacy report.
