Why lock Color Notes With Lock & To Do?

Color Notes With Lock & To Do is a encrypted notes app, the kind of app that tends to hold personal information you would not want on screen if someone borrows your unlocked phone. Notes apps quietly collect some of your most personal writing. 'Encrypted' can mean encrypted in transit, at rest on the server, or end-to-end — only the last keeps the developer out.

Productivity apps tend to collect the work you do in them — documents, notes and files — so User Content is common. The question is whether it syncs to the developer's servers and how it is protected there.

A lock answers one question — who can open the app on this iPhone. It does not change what Color Notes With Lock & To Do sends to its developer; for that, see Color Notes With Lock & To Do's full privacy report.
