Your files are training AI. They shouldn't be.
End-to-end encrypted and based in Europe, Proton Drive keeps your photos, documents, and memories away from Big Tech algorithms, AI training, and US surveillance laws.
A secure encrypted home for your files
From birthday party photos to medical records and passport scans, your personal files belong to you— not to ad platforms or AI models.
Proton Drive uses end-to-end encryption to keep your data private. Only you hold the keys to access your files — not even Proton can see them — so you control your memories, identity, and privacy.
