Encrypted email services

The cluster comprises encrypted email and secure communication services that emphasize end-to-end encryption for personal and business use. The dated history shows five entries scattered from 2012 to 2025, appearing intermittently with no clear trend. Proton Mail, Atomic Mail, and PreVeil lead in traction, though all currently show zero stars.

Each bar is the month a member carries, which is a creation date where the source published one and a crawl date otherwise. Nothing in the index was found before 11 August 2026, and coverage broadened sharply on 14–15 August, so a bar from then on reports how much we found that month, not how much was built; an earlier bar reports how far back a member's own source dated it — not how long we have been watching.
