Create email aliases to protect your online identity and prevent tracking across different web services.

SimpleLogin is an open-source, self-hosted application that allows users to create email aliases to protect their online identity. It functions as an email proxy service that intercepts incoming messages sent to a specific alias and forwards them to a designated primary email address. This process ensures that the primary address remains hidden from the sender, reducing the risk of spam and unauthorized data collection.
The software is deployed as a server-side web application and manages the routing of mail between different domains. Users interact with the system through a web interface to generate new aliases for different websites or services. This setup allows for the isolation of communication channels, meaning a user can assign a unique alias to every service they join to prevent tracking across the web.
The architecture relies on the Flask framework to handle the web interface and the logic required for mail redirection. By hosting the server independently, users maintain full control over their alias database and the routing rules applied to their incoming traffic. The system is designed for users who have the technical capacity to manage their own server infrastructure and who require a dedicated layer of abstraction between their public interactions and their private inbox.
Because it operates as a complete email solution for identity management, the software is suitable for privacy advocates and developers. It provides a concrete method for managing digital footprints by ensuring that no single service possesses the user's actual email address. The use of a self-hosted model ensures that the mapping between aliases and the primary address remains under the user's direct supervision.
