About Proton Calendar

Deep Dive with Clara AI

Proton Calendar is a privacy-focused digital calendar that helps you organize your life while keeping your schedule completely private. Unlike mainstream calendar apps that scan your data for ads or insights, Proton Calendar uses end-to-end encryption, ensuring that only you can see your events, reminders, and details — not even Proton can read them. It’s part of the wider Proton ecosystem, so if you already use Proton Mail, VPN, Drive, or Pass, your calendar integrates smoothly with those services. You can access it on the web or via Android and iOS apps and keep your schedule in sync across devices. Key features include: ✅ Create and manage events and reminders ✅ Recurring events and customizable notifications ✅ Sync across multiple devices and platforms ✅ Import calendars from other services ✅ Share calendars with others (with privacy controls; paid plans let you share more flexibly)
