Proton Sheets Launched — Plus 60% Off Proton Drive

Proton has expanded its privacy-focused suite with Proton Sheets, a new spreadsheet tool built directly into Proton Drive. Alongside the launch, Proton is offering a limited 60% discount on Proton Drive plans, making this a good moment to take a closer look at what Sheets offers and who it’s for.

This post explains what Proton Sheets is, why it matters, and how the current Proton Drive offer works.

What Is Proton Sheets?

Proton Sheets is a privacy-first spreadsheet tool available inside Proton Drive. It’s designed to feel familiar to anyone who has used mainstream spreadsheet apps, while keeping data protected with end-to-end encryption.

With Proton Sheets, your spreadsheet data is encrypted in a way that prevents Proton — or any third party — from accessing the contents. Only you and the people you explicitly share a file with can see what’s inside.

Key features include:

• Familiar spreadsheet functions and formulas
• Charts and basic data visualisation
• Real-time collaboration
• Built-in version history
• End-to-end encryption by default

The goal isn’t to reinvent spreadsheets, but to offer a secure alternative for users who want more control over their data.

Why Proton Sheets Matters

Spreadsheets are widely used for budgets, planning, inventories, and sensitive business or personal information. Most mainstream spreadsheet tools store this data unencrypted, allowing providers to scan content for analytics, advertising, or AI training.

Proton Sheets takes a different approach. By encrypting spreadsheet data end-to-end, Proton removes visibility into file contents and reduces the risk of data being accessed, analysed, or repurposed without your consent.

For privacy-conscious users, journalists, small businesses, or anyone storing sensitive information, this distinction matters.

How Proton Sheets Compares (Briefly)

Most popular spreadsheet tools prioritise convenience and integration across large ecosystems. Privacy-focused tools like Proton Sheets prioritise data protection and user control, even if that means a more deliberate feature rollout.

Proton Sheets may not yet replace every advanced spreadsheet workflow, but it offers a strong foundation for everyday use where privacy is a priority.

The 60% Off Proton Drive Offer Explained

To mark the launch of Proton Sheets, Proton is currently offering a 60% discount on Proton Drive plans. Valid until 5th Jan 2026

Here’s what that means in practical terms:

• Discount: 60% off
• Applies to: Proton Drive Plus (annual plans)
• Includes: Proton Drive storage + Proton Sheets
• Availability: Limited-time launch promotion

Proton Drive Plus also includes the same encryption model used across Proton’s ecosystem, keeping files private by default.

As with most Proton promotions, this offer is aimed at new or upgrading users and may not be permanent.

Who Is Proton Sheets Best For?

Proton Sheets is a good fit if you:

• Want encrypted spreadsheets by default
• Store sensitive personal or work data
• Prefer privacy-first tools over ad-supported platforms
• Already use Proton Mail or Proton Drive
• Want a simple, secure alternative for everyday spreadsheet tasks

If you rely heavily on advanced macros or complex enterprise integrations, you may find Proton Sheets more limited — at least for now.

Final Thoughts

Proton Sheets adds an important piece to Proton’s growing productivity ecosystem. It won’t replace every spreadsheet tool overnight, but it offers something most mainstream platforms don’t: strong privacy by design.

If encrypted storage and data control matter to you, Proton Sheets is worth exploring — and the current Proton Drive discount makes it easier to try without a long-term commitment.
