How that compares to other email apps
Of the 5 email apps compared here, Proton Mail declares collecting data in 5 categories against a median of 6. It declares sharing no data with third parties.
A higher count is not automatically worse — an app that syncs your own data between your devices declares collection just as an ad-funded one does. The sharing column is the sharper signal, because it means the data left the developer.
