Introducing Proton Duo: Unlimited privacy for two

You might think protecting your online privacy is a personal responsibility, but there’s a good chance that your loved ones are still entangled with Big Tech companies. These companies exploit your friends and family’s most sensitive, valuable data to show them tracking-based advertising or expose them to unscrupulous, information-scraping AI tools.

If a partner or family member is still using Google to send emails, store documents, or offload photos, it’s likely they’re inadvertently exposing the sensitive, valuable information you took precautions to protect.

That’s why we’re introducing Proton Duo, a new plan designed to make online privacy easy for two people with 1 TB of storage space. You both get to enjoy your own encrypted email address, calendar, secure storage for files, photos, and passwords, and a VPN to browse securely. With Proton Duo, you will have the peace of mind that comes with knowing your digital lives are truly private. 

For a limited time only, we are offering Proton Duo for $14.99/month with a one-year plan: That’s $60 in annual savings. This is a forever discount, so if you sign up for the promotion, you’ll keep this price forever.

Online privacy made easy

Proton makes online privacy easy. Our apps use end-to-end and zero-access encryption, meaning that no one — not even Proton — can access you or your partner’s information without your explicit permission. Encryption works automatically in the background, so you can send emails, plan your day, or share files as usual while we handle the rest.

Proton Duo includes:

  • Up to 2 users
  • 1 TB of storage space, with 15 GB of bonus storage every year
  • Everything that’s in Proton Unlimited
  • Full access to Proton Mail, Proton Drive, Proton Calendar, Proton Pass, and Proton VPN

And you will save $60 yearly compared to two Proton Unlimited subscriptions.

Proton Duo gives you separate login information, so you can keep your emails, calendars, and files to yourself. You get to decide what to share with your partner or family member. You’ll both enjoy online privacy made easy and get access to unique perks:

  • Get a personal email identity: Share a custom email domain for a more personal family identity to send messages in Proton Mail.
  • Back up your files and photos: Back up your files and photos with 1 TB of end-to-end encrypted storage space. Access them from any device in Proton Drive.
  • Share your calendar: Keep track of schedules and plan events and vacations with a shared Proton Calendar.
  • Secure your passwords: Share a Proton Pass vault with login details for shared online accounts and subscriptions.
  • Collaborate on documents: Plan vacations, manage your budget, or brainstorm together in real-time with Docs in Proton Drive.
  • Browse the web privately: change your IP address and your location, avoid targeted ads and stay safe from malware.
  • Keep your family safe: The Proton Sentinel account protection program and Dark Web Monitoring can protect you from account takeover attacks and data breaches.

Get started today with Proton Duo

Start enjoying the benefits of the Proton Duo plan today. Here’s how to get started:

Making the internet better for everyone

At Proton, we’re on a mission to make the internet better for everyone by offering privacy-focused alternatives to Big Tech — such as the recently launched photo backup or document editor in Proton Drive — and making privacy more accessible with plans that best fit your needs, like Proton Duo.

Unlike other free services that make you pay with your data, you pay Proton to give you security and privacy, which means we’re only incentivized to keep your information safe. Our first and only obligation is to you — and everyone in the Proton community. We recently moved to a not-for-profit structure with the launch of the Proton Foundation to cement our commitment to your privacy even further(new window).

By choosing Proton Duo, you’re not only giving yourself and your partner or family member control over your most sensitive, valuable information, you’re also helping build the internet of the future, where privacy is the default.
