About Aionda Mail
Aionda Mail provides email, calendar and contacts with end-to-end encryption using ML-KEM-1024 combined with X25519. It also offers disposable addresses, encrypted drive storage and video meetings that can be shared by link, with servers in Germany.
The provider describes a zero-knowledge design where the password stays in the browser. Access depends on saved recovery words if the password is forgotten, and the AI assistant is enabled by default with server processing that can be turned off.
