You can use Tuta to send and receive end-to-end encrypted emails, manage a private calendar, and store contacts — all without ads or data tracking. It uses quantum-resistant encryption and a zero-knowledge architecture so only you can access your data. You can use it on Android, iOS, Windows, macOS, Linux, or in a browser. It supports custom domains, alias email addresses, and is fully open source. Businesses can also use it to protect professional communications under GDPR.
