Proton Mail
Proton Mail is a desktop email and calendar app for Mac that gives you focused access to your Proton inbox and schedule.
What is Proton Mail?
Proton Mail is a secure email app for Mac that lets you read, send, and organize email from a dedicated desktop window instead of a browser tab. It is made by Proton Technologies AG and is designed for people who use Proton Mail for personal communication, work, or privacy-focused messaging. The Mac app also includes Proton Calendar access, so you can move between your inbox and schedule in one place. Common tasks include managing folders and labels, handling attachments, switching between accounts, and receiving desktop notifications for new mail. It fits users who want a native desktop workflow for encrypted email while keeping their mailbox synchronized with Proton’s web and mobile services.

Safety overview
Status: Safe
Proton Mail is legitimate email software. It handles your messages, attachments, and account data as part of its normal purpose, and desktop notifications or background activity are expected for a mail app. As with any email service, the main practical precaution is to protect your account with a strong password and two-factor authentication and sign out on shared Macs if others can use the computer.
Recommendation: Keep Proton Mail if you use a Proton email account on this Mac. Remove it only if you no longer want desktop access to your Proton inbox and calendar; doing so will stop local notifications and app-based access, but your account and web access remain available.
