OVERVIEW

About Proton Mail

**Proton Mail** is the original product within the **Proton AG** ecosystem (Geneva, Switzerland) and the flagship of the privacy-first email category — **end-to-end + zero-access encryption** (Proton itself cannot read user emails or attachments), 100M+ users, 100,000+ organisations. Since June 2024 Proton AG is controlled by the **Proton Foundation**, a Swiss non-profit, which structurally rules out future VC / PE acquisition pressure. Pricing: Free (1GB), Mail Plus (~€4.99/mo, 15GB + custom domain), Proton Unlimited (~€9.99/mo bundle with Mail + Drive + Pass + Calendar + Docs + Sheets + VPN). For the full Proton ecosystem profile see `proton-drive` and `protonvpn`. Swiss jurisdiction places `ownership_signal: other` (Switzerland is non-EU but strong-privacy-law); CLOUD Act exposure none.
