Open Source Kotlin Anti-Spam Software

addy.io is a free, open-source Android and Wear OS application for managing email aliases through the addy.io email forwarding service. It helps users protect their primary email addresses by creating disposable or reusable aliases for different websites and contacts. The application connects to hosted addy.io accounts or compatible self-hosted instances. Users can create, edit, deactivate, and delete aliases while managing recipients, domains, usernames, and forwarding rules. Notifications report failed deliveries, domain errors, and other account events. Email sending through aliases is supported using configured addresses. Biometric locking and encrypted local preferences protect sensitive account information. Wear OS integration provides convenient alias management and quick access through smartwatch tiles.
