Proton Drive Privacy Policy Explained: What Therapists Need to Know

April 26, 2026 • 9 min read

If you are a therapist considering Proton Drive for storing client files, you need to understand exactly what their privacy policy covers—and what it doesn't.

This article breaks down the Proton Drive privacy policy in plain English, specifically for UK health practitioners who must comply with GDPR and maintain client confidentiality.

What Is Proton Drive?

Proton Drive is end-to-end encrypted cloud storage built by the team behind Proton Mail. Unlike Google Drive or Dropbox, Proton Drive encrypts your files on your device before they reach Proton's servers. This means Proton cannot read, scan, or access your stored data—even if compelled by law enforcement.

For therapists handling sensitive client notes, intake forms, and session recordings, this architecture is fundamentally different from mainstream alternatives.

What the Proton Drive Privacy Policy Covers

Proton's privacy policy is built on several core principles that matter directly for health practitioners:

1. End-to-End Encryption by Default

All files uploaded to Proton Drive are encrypted on your device before upload. Proton holds the encrypted data but does not hold the decryption keys. Only you (and anyone you explicitly share with) can decrypt and read your files.

This is the critical distinction from services like Google Drive, where the provider holds the keys and can access your content at any time.

2. Swiss Jurisdiction

Proton AG is headquartered in Switzerland. This matters for two reasons:

3. Minimal Data Collection

Proton's privacy policy states they collect only the minimum data necessary to provide the service:

Key takeaway for therapists: Proton does not build advertising profiles, does not scan file content, and does not log access patterns. This is the opposite of how Google Drive and Dropbox operate.

4. Open Source and Independently Audited

Proton Drive's encryption code is open source, meaning independent security researchers can inspect it for vulnerabilities. Proton also undergoes regular independent audits to verify their privacy claims.

For practitioners who need to demonstrate due diligence to regulators, this transparency is valuable. You can point to published audit reports as evidence that your storage provider meets security standards.

5. GDPR Compliance

Proton Drive data is stored within the European Economic Area (EEA), specifically in Switzerland and Germany. This ensures full GDPR compliance for UK and EU practitioners. Data does not leave EEA jurisdiction at any point.

What the Privacy Policy Does NOT Cover

No system is perfect. Here are the limitations therapists should be aware of:

For therapists: Never use public sharing links for sensitive client documents. Use Proton Drive's encrypted sharing features, which require authentication and maintain end-to-end encryption.

Completing Your Privacy Stack

Proton Drive secures your files. But a therapy practice needs more than secure storage. To build a fully compliant operation, you need every layer protected:

From Secure Storage to Secure Presence

Proton Drive protects your files. But your website is where clients first encounter your practice. If your files are encrypted but your website runs on shared hosting with no data sovereignty guarantees, your privacy stack has a gap.
