About

An unofficial desktop client for ProtonMail done with electron nativefier.

I just did it because I didnt want to open the browser every time I wanted to check my protonmail, I dont like to use Proton Bridge which is buggy and I prefer to access protonmail without an intermediary software while keeping desktop notifications and a dedicated app.

Security

No known CVEs for ProtonClient.

Coverage is best-effort and depends on a winget package mapping to an NVD CPE entry. Absence here is not a guarantee of safety.
